Window leaked exceptions are usually caused by dialogs which are not dismissed properly. ie if you are planning to dismiss a dialog in Onpostexecute of asynctask and the activity that created it has ended it will throw a window leak. Make sure you dimisss dialog in onPause of the activity.
4Whenever you initiate a ProgressDialog, that should be dismissed properly after the background task gets done, or even cancellation of the background running task. So,
instead of mProgressBar.hide(); use mProgressBar.dismiss();
you will not get android.view.WindowLeaked error
hope this helps
1Check if you are using finish() function before the mDialog.show() function. If it is remove the finish() and add it after the show().
whren you miss this code : mProgressDialog.dismis(); that time may be you will receive this type of error.
Another scenario where this error occurs is when the app crushes while a dialog is shown. Look above this error for additional errors.
In onStop() or onDestroy() callback, dismiss the dialog using dialogName.dismiss();
Also do a null check. That is:
if (dialogName != null) { dialogName.dismiss();
}The problem is AsyncTask.
new AsyncTask<Void, Void, String>() { CustomDialog mProgressBar = new CustomDialog(MobileConnectActivity.this, R.style.dialog); ....
}You create a progress bar inside async task which makes a problem when you move to another activity.
For this before dismiss or show()
if(!isFinishing() && dialog != null) { dialog.dismiss();}Usage of isFinishing()
* Check to see whether this activity is in the process of finishing, * either because you called {@link #finish} on it or someone else * has requested that it finished. This is often used in * {@link #onPause} to determine whether the activity is simply pausing or * completely finishing. * * @return If the activity is finishing, returns true; else returns false.Simply dismissing the dialog was not enough to get rid of the error for me. It turns out my code was holding onto a reference to the dialog even after it was dismissed. The key for me was to set that reference to null after dismissing the dialog.
The problem for me was happening because I used the android:noHistory="true" for the activity that was causing the problem, and it only happened on Android 6.0 API 23.
