android – getting exception "IllegalStateException: Can not perform this action after onSaveInstanceState"

Posted by: admin March 10, 2020 Leave a comment


I have a Live Android application, and from market i have received following stack trace and i have no idea why its happening as its not happening in application code but its getting caused by some or the other event from the application (assumption)

I am not using Fragments, still there is a reference of FragmentManager.
If any body can throw some light on some hidden facts to avoid this type of issue:

How to&Answers:

This is the most stupid bug I have encountered so far. I had a Fragment application working perfectly for API < 11, and Force Closing on API > 11.

I really couldn’t figure out what they changed inside the Activity lifecycle in the call to saveInstance, but I here is how I solved this :

protected void onSaveInstanceState(Bundle outState) {
    //No call for super(). Bug on API Level > 11.

I just do not make the call to .super() and everything works great. I hope this will save you some time.

EDIT: after some more research, this is a known bug in the support package.

If you need to save the instance, and add something to your outState Bundle you can use the following :

protected void onSaveInstanceState(Bundle outState) {
    outState.putString("WORKAROUND_FOR_BUG_19917_KEY", "WORKAROUND_FOR_BUG_19917_VALUE");

EDIT2: this may also occur if you are trying to perform a transaction after your Activity is gone in background. To avoid this you should use commitAllowingStateLoss()

EDIT3: The above solutions were fixing issues in the early support.v4 libraries from what I can remember. But if you still have issues with this you MUST also read @AlexLockwood ‘s blog : Fragment Transactions & Activity State Loss

Summary from the blog post (but I strongly recommend you to read it) :

  • NEVER commit() transactions after onPause() on pre-Honeycomb, and onStop() on post-Honeycomb
  • Be careful when committing transactions inside Activity lifecycle methods. Use onCreate(), onResumeFragments() and onPostResume()
  • Avoid performing transactions inside asynchronous callback methods
  • Use commitAllowingStateLoss() only as a last resort


Looking in Android source code on what causes this issue gives that flag mStateSaved in FragmentManagerImpl class (instance available in Activity) has value true. It is set to true when the back stack is saved (saveAllState) on call from Activity#onSaveInstanceState.
Afterwards the calls from ActivityThread don’t reset this flag using available reset methods from FragmentManagerImpl#noteStateNotSaved() and dispatch().

The way I see it there are some available fixes, depending on what your app is doing and using:

Good ways

Before anything else: I would advertise Alex Lockwood article. Then, from what I’ve done so far:

  1. For fragments and activities that don’t need to keep any state information, call commitAllowStateLoss. Taken from documentation:

    Allows the commit to be executed after an activity’s state is saved. This is dangerous because the commit can be lost if the activity needs to later be restored from its state, so this should only be used for cases where it is okay for the UI state to change unexpectedly on the user`. I guess this is alright to use if the fragment is showing read-only information. Or even if they do show editable info, use the callbacks methods to retain the edited info.

  2. Just after the transaction is commit (you just called commit()), make a call to FragmentManager.executePendingTransactions().

Not recommended ways:

  1. As Ovidiu Latcu mentioned above, don’t call super.onSaveInstanceState(). But this means you will lose the whole state of your activity along with fragments state.

  2. Override onBackPressed and in there call only finish(). This should be OK if you application doesn’t use Fragments API; as in super.onBackPressed there is a call to FragmentManager#popBackStackImmediate().

  3. If you are using both Fragments API and the state of your activity is important/vital, then you could try to call using reflection API FragmentManagerImpl#noteStateNotSaved(). But this is a hack, or one could say it’s a workaround. I don’t like it, but in my case it’s quite acceptable since I have a code from a legacy app that uses deprecated code (TabActivity and implicitly LocalActivityManager).

Below is the code that uses reflection:

protected void onSaveInstanceState(Bundle outState) {

@SuppressWarnings({ "rawtypes", "unchecked" })
private void invokeFragmentManagerNoteStateNotSaved() {
     * For post-Honeycomb devices
    if (Build.VERSION.SDK_INT < 11) {
    try {
        Class cls = getClass();
        do {
            cls = cls.getSuperclass();
        } while (!"Activity".equals(cls.getSimpleName()));
        Field fragmentMgrField = cls.getDeclaredField("mFragments");

        Object fragmentMgr = fragmentMgrField.get(this);
        cls = fragmentMgr.getClass();

        Method noteStateNotSavedMethod = cls.getDeclaredMethod("noteStateNotSaved", new Class[] {});
        noteStateNotSavedMethod.invoke(fragmentMgr, new Object[] {});
        Log.d("DLOutState", "Successful call for noteStateNotSaved!!!");
    } catch (Exception ex) {
        Log.e("DLOutState", "Exception on worka FM.noteStateNotSaved", ex);



Such an exception will occur if you try to perform a fragment transition after your fragment activity’s onSaveInstanceState() gets called.

One reason this can happen, is if you leave an AsyncTask (or Thread) running when an activity gets stopped.

Any transitions after onSaveInstanceState() is called could potentially get lost if the system reclaims the activity for resources and recreates it later.


Simply call super.onPostResume() before showing your fragment or move your code in onPostResume() method after calling super.onPostResume(). This solve the problem!


This can also happen when calling dismiss() on a dialog fragment after the screen has been locked\blanked and the Activity + dialog’s instance state has been saved. To get around this call:


Literally every single time I’m dismissing a dialog i don’t care about it’s state anymore anyway, so this is ok to do – you’re not actually losing any state.


Short And working Solution :

Follow Simple Steps :

Step 1 : Override onSaveInstanceState state in respective fragment. And remove super method from it.

public void onSaveInstanceState(Bundle outState) {

Step 2 : Use CommitAllowingStateLoss(); instead of commit(); while fragment operations.



I think Lifecycle state can help to prevent such crash starting from Android support lib v26.1.0 you can have the following check:

if (getLifecycle().getCurrentState().isAtLeast(Lifecycle.State.STARTED)){
  // Do fragment's transaction commit

or you can try:

this worked for me… found this out on my own… hope it helps you!

1) do NOT have a global “static” FragmentManager / FragmentTransaction.

2) onCreate, ALWAYS initialize the FragmentManager again!

sample below :-

public abstract class FragmentController extends AnotherActivity{
protected FragmentManager fragmentManager;
protected FragmentTransaction fragmentTransaction;
protected Bundle mSavedInstanceState;

protected void onCreate(Bundle savedInstanceState) {
    mSavedInstanceState = savedInstanceState;

protected void setDefaultFragments() {
    fragmentManager = getSupportFragmentManager();
    //check if on orientation change.. do not re-add fragments!
    if(mSavedInstanceState == null) {
        //instantiate the fragment manager

        fragmentTransaction = fragmentManager.beginTransaction();

        //the navigation fragments
        NavigationFragment navFrag = new NavigationFragment();
        ToolbarFragment toolFrag = new ToolbarFragment();

        fragmentTransaction.add(R.id.NavLayout, navFrag, "NavFrag");
        fragmentTransaction.add(R.id.ToolbarLayout, toolFrag, "ToolFrag");

        //add own fragment to the nav (abstract method)


I was always getting this when I tried to show fragment in onActivityForResult() method, so the problem was next:

  1. My Activity is paused and stopped, which means, that onSaveInstanceState() was called already (for both pre-Honeycomb and post-Honeycomb devices).
  2. In case of any result I made transaction to show/hide fragment, which causes this IllegalStateException.

What I made is next:

  1. Added value for determining if action I want was done (e.g. taking photo from camere – isPhotoTaken) – it can be boolean or integer value depending how much different transactions you need.
  2. In overriden onResumeFragments() method I checked for my value and after made fragment transactions I needed. In this case commit() was not done after onSaveInstanceState, as state was returned in onResumeFragments() method.


I solved the issue with onconfigurationchanged. The trick is that according to android activity life cycle, when you explicitly called an intent(camera intent, or any other one); the activity is paused and onsavedInstance is called in that case. When rotating the device to a different position other than the one during which the activity was active; doing fragment operations such as fragment commit causes Illegal state exception. There are lots of complains about it. It’s something about android activity lifecycle management and proper method calls.
To solve it I did this:
1-Override the onsavedInstance method of your activity, and determine the current screen orientation(portrait or landscape) then set your screen orientation to it before your activity is paused. that way the activity you lock the screen rotation for your activity in case it has been rotated by another one.
2-then , override onresume method of activity, and set your orientation mode now to sensor so that after onsaved method is called it will call one more time onconfiguration to deal with the rotation properly.

You can copy/paste this code into your activity to deal with it:

protected void onSaveInstanceState(Bundle outState) {       

    Toast.makeText(this, "Activity OnResume(): Lock Screen Orientation ", Toast.LENGTH_LONG).show();
    int orientation =this.getDisplayOrientation();
    //Lock the screen orientation to the current display orientation : Landscape or Potrait

//A method found in stackOverflow, don't remember the author, to determine the right screen orientation independently of the phone or tablet device 
public int getDisplayOrientation() {
    Display getOrient = getWindowManager().getDefaultDisplay();

    int orientation = getOrient.getOrientation();

    // Sometimes you may get undefined orientation Value is 0
    // simple logic solves the problem compare the screen
    // X,Y Co-ordinates and determine the Orientation in such cases
    if (orientation == Configuration.ORIENTATION_UNDEFINED) {
        Configuration config = getResources().getConfiguration();
        orientation = config.orientation;

        if (orientation == Configuration.ORIENTATION_UNDEFINED) {
        // if height and widht of screen are equal then
        // it is square orientation
            if (getOrient.getWidth() == getOrient.getHeight()) {
                orientation = Configuration.ORIENTATION_SQUARE;
            } else { //if widht is less than height than it is portrait
                if (getOrient.getWidth() < getOrient.getHeight()) {
                    orientation = Configuration.ORIENTATION_PORTRAIT;
                } else { // if it is not any of the above it will defineitly be landscape
                    orientation = Configuration.ORIENTATION_LANDSCAPE;
    return orientation; // return value 1 is portrait and 2 is Landscape Mode

public void onResume() {
    Toast.makeText(this, "Activity OnResume(): Unlock Screen Orientation ", Toast.LENGTH_LONG).show();


I had the same problem, getting IllegalStateException, but replacing all my calls to commit() with commitAllowingStateLoss() did not help.

The culprit was a call to DialogFragment.show().

I surround it with

try {
    dialog.show(transaction, "blah blah");
catch(IllegalStateException e) {

and that did it. OK, I don’t get to show the dialog, but in this case that was fine.

It was the only place in my app where I first called FragmentManager.beginTransaction() but never called commit() so I did not find it when I looked for “commit()”.

The funny thing is, the user never leaves the app. Instead the killer was an AdMob interstitial ad showing up.


My solution for that problem was

In fragment add methods:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    guideMapFragment = (SupportMapFragment)a.getSupportFragmentManager().findFragmentById(R.id.guideMap);
    guideMap = guideMapFragment.getMap();

public void onDestroyView() {
    SherlockFragmentActivity a = getSherlockActivity();
    if (a != null && guideMapFragment != null) {
        try {
            Log.i(LOGTAG, "Removing map fragment");
            guideMapFragment = null;
        } catch(IllegalStateException e) {
            Log.i(LOGTAG, "IllegalStateException on exit");

May be bad, but couldn’t find anything better.


I got this issue.But I think this problem is not related to commit and commitAllowStateLoss.

The following stack trace and exception message is about commit().

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
at android.support.v4.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1341)
at android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1352)
at android.support.v4.app.BackStackRecord.commitInternal(BackStackRecord.java:595)
at android.support.v4.app.BackStackRecord.commit(BackStackRecord.java:574)

But this exception was caused by onBackPressed()

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
at android.support.v4.app.FragmentManagerImpl.checkStateLoss(Unknown Source)
at android.support.v4.app.FragmentManagerImpl.popBackStackImmediate(Unknown Source)
at android.support.v4.app.FragmentActivity.onBackPressed(Unknown Source)

They were all caused by checkStateLoss()

private void checkStateLoss() {
    if (mStateSaved) {
        throw new IllegalStateException(
                "Can not perform this action after onSaveInstanceState");
    if (mNoTransactionsBecause != null) {
        throw new IllegalStateException(
                "Can not perform this action inside of " + mNoTransactionsBecause);

mStateSaved will be true after onSaveInstanceState.

This problem rarely happens.I have never encountered this problem.I can not reoccurrence the problem.

I found issue 25517

It might have occurred in the following circumstances

  1. Back key is called after onSaveInstanceState, but before the new activity is started.

  2. use onStop() in code

I’m not sure what the root of the problem is.
So I used an ugly way.

public void onBackPressed() {

    }catch (IllegalStateException e){
        // can output some information here


I have got the same issue in my App. I have been solved this issue just calling the super.onBackPressed(); on previous class and calling the commitAllowingStateLoss() on the current class with that fragment.


onSaveInstance will be called if a user rotates the screen so that it can load resources associated with the new orientation.

It’s possible that this user rotated the screen followed by pressing the back button (because it’s also possible that this user fumbled their phone while using your app)



fragment.isResumed() checking helps me in onDestroyView w/o using onSaveInstanceState method.


Same issue from me and after a day long analysis of all articles, blog and stackoverflow i’ve found a simple solution. Don’t use savedInstanceState at all, this is the condition with one line of code. On the fragment code:

public void onCreate(Bundle savedInstanceState) {


This happens whenever you are trying to load a fragment but the activity has changed its state to onPause().This happens for example when you try to fetch data and load it to the activity but by the time the user has clicked some button and has moved to next activity.

You can solve this in two ways

You can use transaction.commitAllowingStateLoss() instead of transaction.commit() to load fragment but you may end up losing commit operation that is done.


Make sure that activity is in resume and not going to pause state when loading a fragment.
Create a boolean and check if activity is not going to onPause() state.

public void onResume() {
    mIsResumed = true;

public void onPause() {
    mIsResumed = false;

then while loading fragment check if activity is present and load only when activity is foreground.

 //load the fragment


Thanks @gunar, but I think there is a better way.

According to doc :

 * If you are committing a single transaction that does not modify the
 * fragment back stack, strongly consider using
 * {@link FragmentTransaction#commitNow()} instead. This can help avoid
 * unwanted side effects when other code in your app has pending committed
 * transactions that expect different timing.
 * @return Returns true if there were any pending transactions to be
 * executed.
public abstract boolean executePendingTransactions();

So use commitNow to replace:



Well, after trying all the above solutions without success (because basically i dont have transactions).

On my case i was using AlertDialogs and ProgressDialog as fragments that, sometimes, on rotation, when asking for the FragmentManager, the error rises.

I found a workaround mixing some many similar posts:

Its a 3 step solution, all done on your FragmentActivity (in this case, its called GenericActivity):

private static WeakReference<GenericActivity> activity = null; //To avoid bug for fragments: Step 1 of 3

protected void onCreate(Bundle savedInstanceState){
    //To avoid bug for fragments: Step 2 of 3
    activity = new WeakReference<GenericActivity>(this);

public FragmentManager getSupportFragmentManager(){
    //To avoid bug for fragments: Step 3 of 3
    if (this == activity.get()) {
        return super.getSupportFragmentManager();
    return activity.get().getSupportFragmentManager();


When i use startactivity in one fragment, i will get this exception;

When i change to use startactivityforresult, the exception is gone 🙂

So the easy way to fix it is use the startActivityForResult api 🙂


I was getting this exception when I was pressing back button to cancel intent chooser on my map fragment activity.
I resolved this by replacing the code of onResume()(where I was initializing the fragment and committing transaction) to onStart() and the app is working fine now.
Hope it helps.


This is fixed in Android 4.2 and also in the support library’s source.[*]

For details of the cause (and work-arounds) refer to the the Google bug report:

If you’re using the support library then you shouldn’t have to worry about this bug (for long)[*]. However, if you’re using the API directly (i.e. Not using the support library’s FragmentManager) and targeting an API below Android 4.2 then you will need to try one of the work-arounds.

[*] At the time of writing the Android SDK Manager is still distributing an old version that exhibits this bug.

Edit I’m going to add some clarification here because I’ve obviously somehow confused whoever down-voted this answer.

There are several different (but related) circumstances that can cause this exception to be thrown. My answer above is referring to the specific instance discussed in the question i.e. a bug in Android which has subsequently been fixed. If you’re getting this exception for another reason it’s because you’re adding/removing fragments when you shouldn’t be (after fragment states have been saved). If you’re in such a situation then perhaps “Nested Fragments – IllegalStateException “Can not perform this action after onSaveInstanceState”” can be of use to you.


After researching a bit the solution to this problem is to do your fragment commits in the onresume.

Source: https://wenchaojames.wordpress.com/2013/01/12/illegalstateexception-from-onactivityresult/


My use case: I have used listener in fragment to notify activity that some thing happened. I did new fragment commit on callback method. This works perfectly fine on first time. But on orientation change the activity is recreated with saved instance state. In that case fragment is not created again implies that the fragment have the listener which is old destroyed activity. Any way the call back method will get triggered on action. It goes to destroyed activity which cause the issue. The solution is to reset the listener in fragment with current live activity. This solve the problem.


What I found is that if another app is dialog type and allows touches to be sent to background app then almost any background app will crash with this error.
I think we need to check every time a transaction is performed if the instance was saved or restored.


In my case, with the same error exception, i put the “onBackPressed()” in a runnable (you can use any of your view):

myView.post(new Runnable() {
                    public void run() {

I do not understand why, but it works!


You may be calling fragmentManager.popBackStackImmediate(); when activity is paused. Activity is not finished but is paused and not on foreground. You need to check whether activity is paused or not before popBackStackImmediate().


I noticed something very interesting. I have in my app the option to open the phone’s gallery and the device asks what app to use, there I click on the gray area away from the dialog and saw this issue. I noticed how my activity goes from onPause, onSaveInstanceState back to onResume, it doesn’t happen to visit onCreateView. I am doing transactions at onResume. So what I ended up doing is setting a flag being negated onPause, but being true onCreateView. if the flag is true onResume then do onCommit, otherwise commitAllowingStateLoss. I could go on and waste so much time but I wanted to check the lifecycle. I have a device which is sdkversion 23, and I don’t get this issue, but I have another one which is 21, and there I see it.


you can use FragmentActivity.onStart before popBackStackImmediate

like this:

public void backStackFragment() {

public void start(){
    FragmentActivity a = getActivity();
    if(a instanceof DepositPlanPadActivity){
    if(a instanceof SmallChangePlanPad){
        if(a instanceof UserCenterActivity){
