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

I've faced with SIGSEGV on Android 4.4.4 (Nexuses, Samsungs) And it turned out that fatal error was in parsing null String using DecimalFormat

 static DecimalFormat decimalFormat = new DecimalFormat("###,###.###");
 void someMethod(String value) {
...
    Number number = decimalFormat.parse(value);//value is null, SIGSEGV will happen`
...
}

On Android > 21 it was handled successfully with try/catch
