Android: Permission Denial: starting Intent with revoked permission android.permission.CAMERA

Posted by: admin April 23, 2020 Leave a comment

Questions:

I’m trying to start a ACTION_IMAGE_CAPTURE activity in order to take a picture in my app and I’m getting the error in the subject.

Stacktrace:

FATAL EXCEPTION: main
Process: il.ac.shenkar.david.todolistex2, PID: 3293
java.lang.SecurityException: Permission Denial: starting Intent { act=android.media.action.IMAGE_CAPTURE cmp=com.google.android.GoogleCamera/com.android.camera.CaptureActivity } from ProcessRecord{22b0eb2 3293:il.ac.shenkar.david.todolistex2/u0a126} (pid=3293, uid=10126) 
with revoked permission android.permission.CAMERA

The camera permissions is added to the manifest.xml fie:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />

Here is the call to open the camera:

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.statusgroup);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId)
        {
            RadioButton rb = (RadioButton) findViewById(R.id.donestatusRBtn);
            if(rb.isChecked())
            {
                Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
                    startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
                }
            }
        }
    });
How to&Answers:

hi you can use these permission in your manifest file with other permission,

<uses-feature
    android:name="android.hardware.camera.any"
    android:required="true" />
<uses-feature
    android:name="android.hardware.camera.autofocus"
    android:required="false" />

If still it not working then may be you are using android M,SO you need to programmatically add permissions.

here is example

hi here is few steps for setup permission for android M and remember you should declare same permission in manifest file as well.

Step 1. Declare global variable :

 public final int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 1;

//requests for runtime time permissions

 String CAMERA_PERMISSION = android.Manifest.permission.CAMERA;


 String READ_EXTERNAL_STORAGE_PERMISSION = android.Manifest.permission.READ_EXTERNAL_STORAGE;


String WRITE_EXTERNAL_STORAGE_PERMISSION = android.Manifest.permission.WRITE_EXTERNAL_STORAGE;


// for security permissions
@DialogType
private int mDialogType;
private String mRequestPermissions = "We are requesting the camera and Gallery permission as it is absolutely necessary for the app to perform it\'s functionality.\nPlease select \"Grant Permission\" to try again and \"Cancel \" to exit the application.";
private String mRequsetSettings = "You have rejected the camera and Gallery permission for the application. As it is absolutely necessary for the app to perform you need to enable it in the settings of your device.\nPlease select \"Go to settings\" to go to application settings in your device and \"Cancel \" to exit the application.";
private String mGrantPermissions = "Grant Permissions";
private String mCancel = "Cancel";
private String mGoToSettings = "Go To Settings";
private String mPermissionRejectWarning = "Cannot Proceed Without Permissions</string>
<string name="explanation_permission_location_request">We are requesting the location permission as it is necessary for the app to perform search functionality properly.\nPlease select \"Grant Permission\" to try again and \"Cancel \" to deny permission.";

// create dialog like this.

// type of dialog opened in MainActivity
 @IntDef({DialogType.DIALOG_DENY, DialogType.DIALOG_NEVER_ASK})
 @Retention(RetentionPolicy.SOURCE)
 @interface DialogType {
    int DIALOG_DENY = 0, DIALOG_NEVER_ASK = 1;
 }

Step 2. Use this code in your main activity

@TargetApi(Build.VERSION_CODES.M)
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED && grantResults[2] == PackageManager.PERMISSION_GRANTED) {
                // Call your camera here.
            } else {
                boolean showRationale1 = shouldShowRequestPermissionRationale(CAMERA_PERMISSION);
                boolean showRationale2 = shouldShowRequestPermissionRationale(READ_EXTERNAL_STORAGE_PERMISSION);
                boolean showRationale3 = shouldShowRequestPermissionRationale(WRITE_EXTERNAL_STORAGE_PERMISSION);
                if (showRationale1 && showRationale2 && showRationale3) {
                    //explain to user why we need the permissions
                    mDialogType = ValueConstants.DialogType.DIALOG_DENY;
                    // Show dialog with 
                    openAlertDialog(mRequestPermissions, mGrantPermissions, mCancel, this, MyActivity.this);
                } else {
                    //explain to user why we need the permissions and ask him to go to settings to enable it
                    mDialogType = ValueConstants.DialogType.DIALOG_NEVER_ASK;
                    openAlertDialog(mRequsetSettings, mGoToSettings, mCancel, this, MyActivity.this);
                }
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

//check for camera and storage access permissions
@TargetApi(Build.VERSION_CODES.M)
private void checkMultiplePermissions(int permissionCode, Context context) {

    String[] PERMISSIONS = {CAMERA_PERMISSION, READ_EXTERNAL_STORAGE_PERMISSION, WRITE_EXTERNAL_STORAGE_PERMISSION};
    if (!hasPermissions(context, PERMISSIONS)) {
        ActivityCompat.requestPermissions((Activity) context, PERMISSIONS, permissionCode);
    } else {
        // Open your camera here.
    }
}

private boolean hasPermissions(Context context, String... permissions) {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

Step 3. Call this method in your oncreate method,

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            checkMultiplePermissions(REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS, MyActivity.this);
   } else {
            // Open your camera here.
   }

Step 4. Dialog for permission deny

public static void openAlertDialog(String message, String positiveBtnText, String negativeBtnText,
                            final OnDialogButtonClickListener listener,Context mContext) {

    AlertDialog.Builder builder = new AlertDialog.Builder(mContext, R.style.AlertDialogCustom);
    builder.setPositiveButton(positiveBtnText, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            dialogInterface.dismiss();
            listener.onPositiveButtonClicked();
        }
    });
    builder.setPositiveButton(positiveBtnText, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            dialogInterface.dismiss();
            listener.onNegativeButtonClicked();
        }
    });

    builder.setTitle(mContext.getResources().getString(R.string.app_name));
    builder.setMessage(message);
    builder.setIcon(android.R.drawable.ic_dialog_alert);
    builder.setCancelable(false);
    builder.create().show();
}

// Create this interface

public interface OnDialogButtonClickListener {

void onPositiveButtonClicked();

void onNegativeButtonClicked();
}

and implement this in your activity where need to add permissions.

@Override
public void onPositiveButtonClicked() {
    switch (mDialogType) {
        case ValueConstants.DialogType.DIALOG_DENY:
            checkMultiplePermissions(REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS, MyActivity.this);
            break;
        case ValueConstants.DialogType.DIALOG_NEVER_ASK:
            redirectToAppSettings(MyActivity.this);
            break;

    }
}

@Override
public void onNegativeButtonClicked() {

}

And anyone permission you can call from here and every result you can get in override method onRequestPermissionsResult this one.

thankyou

hope this will help you (Y).

Answer:

Remove this permission

  <uses-permission android:name="android.permission.CAMERA"/>

I faced this error executing my app in android 7. After tests I noticed user permission wasn’t in project A but it was in project B, that I only tested in android 5 devices. So I remove that permission in project B in order to run it on other device that targets android 7 and it finally could open.

In adittion I added the fileprovider code that Android suggests here https://developer.android.com/training/camera/photobasics.html
Hope this helps.

4- Select Camera of the list.

5- Look for your Application in the provided list.

6- Enable Camera.

Now you can use your camera on your emulator 🙂

Answer:

private String [] permissions = {"android.permission.WRITE_EXTERNAL_STORAGE", "android.permission.ACCESS_FINE_LOCATION", "android.permission.READ_PHONE_STATE", "android.permission.SYSTEM_ALERT_WINDOW","android.permission.CAMERA"};

on your OnCreate add this:

int requestCode = 200;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    requestPermissions(permissions, requestCode);
}

Answer:

In case anyone else get’s this issue, my problem was that the app wasn’t requesting any permissions when I ran it. It seems xiaomi devices automatically deny permissions to apps installed through adb. I just enabled the permissions through settings and it worked.

Answer:

in your androidManifest, you have to add :

 <uses-feature android:name="android.hardware.camera" />

here is an full Manifest example of android camera project
