Fatal Exception: java.lang.IllegalStateException

Please complete the following information:

• Library Version 1.2.9
• Affected Device(s) Samsung, Xiaomi, HUAWEI, OPPO OS 8,9,10

The Bug:

I’m using only showAlignTop method, but in some cases this crash is popping on my Firebase Crashlytics.

The specified child already has a parent. You must call removeView() on the child's parent first.

Possible solution:

Was not able to full reproduce yet, but maybe we can find the right part of the library and to some parent check, like

if(tv.getParent() != null) {
    ((ViewGroup)tv.getParent()).removeView(tv); // <- fix
}
layout.addView(tv);

@Canato Hmm… I think the balloon should be shown when the contentView has no parent view for preventing the concurrency issue. I will test and add some more conditions on the show method. Thanks for your report 😃
