Good day.I have an weird issue to which none of examples in stack overflow has worked.I am opening an gallery,after which i am redirecting user to crop intent.Important to mention that this only happens on android N and not below devices.The issue is that this exception is thrown as soon as the crop is done..I dont know what causes this,but actually here is how i start crop intent.
Intent cropIntent = new Intent("com.android.camera.action.CROP");
cropIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri outPutUri = FileProvider.getUriForFile(activity, activity.getApplicationContext().getPackageName() + ".provider", new File(output));
Uri photoURI = FileProvider.getUriForFile(activity, activity.getApplicationContext().getPackageName() + ".provider", new File(path));
activity.grantUriPermission("com.android.camera.action.CROP", outPutUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
activity.grantUriPermission("com.android.camera.action.CROP", photoURI, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
cropIntent.setDataAndType(photoURI, "image/*");
cropIntent.putExtra("crop", "true");
cropIntent.putExtra("aspectX", aspectX);
cropIntent.putExtra("aspectY", aspectY);
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, outPutUri);
activity.startActivityForResult(cropIntent, CROP_REQUEST);
I have granted the Uri permission,have added these to manifest
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
I have tried all stack over flow answer examples,there is no more issue on stack overflow with this scenario and not any of them have worked.So what is the issue with android N ?Should it be so hard?
This is the exception which is being thrown
