I am getting this error when hitting the “Login With Facebook” (Simple login button).
I have Google, and read other topics here – but I can not see any thing matching my issue.
I am adding Login.java class below.
public class Login extends Activity {
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_login);
CallbackManager callbackManager = CallbackManager.Factory.create();
LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions("public_profile", "email", "user_friends");
// Other app specific specialization
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.i("Login", "Logged in: ");
Intent i = new Intent(Login.this, MainActivity.class);
startActivity(i);
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
// App code
Log.i("Error" , "Error");
}
});
}
}

Answer：
This can happen when the user has the native Facebook App installed.
You can suppress the attempt to open it by initializing the LoginManager‘s LoginBehaviour:
// Don't allow the Facebook App to open.
LoginManager.getInstance().setLoginBehavior(LoginBehavior.WEB_VIEW_ONLY);
Answer：
I too had this issue. Mine however was a login call made within the FBActivity.OnResume method for callbacks to login after accepting fb perms.
I simply moved the request into the profile tracker in the onCreate method
ProfileTracker profileTracker = new ProfileTracker() {
@Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile currentProfile) {
Profile.fetchProfileForCurrentAccessToken();
if(currentProfile != null) {
String fbUserId = currentProfile.getId();
profileUrl = currentProfile.getProfilePictureUri(200, 200).toString();
Log.d("FB profile", "got new/updated profile from thread " + fbUserId);
// jump if logged in already
GetFacebookProfileAndJump(currentProfile);
}
}
};
Also ensure your OnCreate super is as follows
FacebookSdk.sdkInitialize(getApplicationContext());
mCallbackmanager = CallbackManager.Factory.create();
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fbauth_);
…
Answer：
You should add this to your acctivity
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
but if your using parse SDK add this
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
ParseFacebookUtils.onActivityResult(requestCode, resultCode, data);
}
Answer：
I had the same problem, and solved by putting the facebook_app_id to strings.xml instead of a constant:
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/facebook_app_id" />
Answer：
In my case i forgot to add application package name and class name on the developer page of facebook. After i added this information then it worked.
Answer：
I have struggled with this problem and I fixed with multidex enabled
add this in your build file
multiDexEnabled true
also this code in your activity
@Override
protected void attachBaseContext(Context context) {
super.attachBaseContext(context);
MultiDex.install(this);
}
after adding this in your build gradle dependencies
compile 'com.android.support:multidex:1.0.1'
Answer：
Actually this is happend. Because of the onActivityResult method has not implemented in side your Activity and also you must call
callbackManager.onActivityResult(requestCode, resultCode, data);
method inside this method. I am sure 100% your problem resolved.
