Android Fatal signal 11 (SIGSEGV) at 0x636f7d89 (code=1). How can it be tracked down?

Question

I\'ve been reading the other posts on tracking down the reasons for getting a SIGSEGV in an Android app. I plan to scour my app for possible NullPointers relate

Answer 1

For me that issue was due to a bad cast between two activities. I recently moved this method from Activity1 to another 2. Doing so, the refactor left this explicit cast as it was before. So instead of doing

((Activity1) mainActivity).hideDialog();

I was supposed to do

((Activity2) mainActivity).hideDialog();

Note: But this error did not happen on android 8.0 I'm not yet sure why.

*** Hope it helps.
