Answer 1

You must need to dismiss/cancel your dialog once activity is finishing. It occurs usually if dialogs are not dismissed before Activity is ended.

Answer 2

I don't know does this help but at me problem's were causing multidex. At build.gradle

multiDexEnabled false

Answer 3

You can also get a WindowLeaked exception if you're not in the UI thread when attempting to show the dialog. Easy fix:

this.runOnUiThread(new Runnable() {
    @Override
    public void run() {
        // show dialog here
    }
});

Answer 4

You get error because ProgressDialog is running while your Activity is destroyed. You should dismiss dialog before starting new Activity.

.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
  public void onClick(DialogInterface dialog, int id) {
      if (alertDialog != null && alertDialog.isShowing()) {
          alertDialog.dismiss();
      }
      Intent i = new Intent(FirstActivity.this, SecondActivity.class);
      startActivity(i);
  }
});

I hope it helps!

Answer 5

Dismiss the alertDialog in onPause() method. i.e. call alertDialog.dismiss()

Note : WindowLeaked exceptions are occured usually if dialogs are not dismissed before Activity is ended.

Check in your manifest if you have setted internet permissions:
