NullPointerException when calling doneLoadingAnimation #40

Closed Lexycon closed 6 years ago

Lexycon commented 6 years ago

Well, I get a NPE when calling doneLoadingAnimation. I don't get it why, actually I have some more buttons in different fragments and they are working perfectly. If I debug and compare both circularProgressButton variables, they don't have any difference. circularProgressButton is not Null. Used version 1.8.4 and 1.12.0.

Edit: I have a callback/interface in the AsyncTask to the Fragment, which will then call this method. I guess this could be the issue?, but actually I am doing the same in the other fragments...

Well that was a fail by me. I had to call the doneLoadingAnimation inside runOnUiThread(), because my callback was obv. executed in the Asynctask...

hii i am try your library

run time exception throw java.lang.NullPointerException use in

Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.category_bg); int color = Color.parseColor("#FF4081"); btn.doneLoadingAnimation(color, largeIcon);
