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 faced this issue moment ago, after migrating from android.support to androidx.

The problem was renderscript.

Solution: I removed from my build.gradle those two lines:

renderscriptTargetApi 21
renderscriptSupportModeEnabled true

after that project building failed, because of unresolved references:

import androidx.renderscript.Allocation;
import androidx.renderscript.Element;
import androidx.renderscript.RenderScript;
import androidx.renderscript.ScriptIntrinsicBlur;

so I've changed them to:

import android.renderscript.Allocation;
import android.renderscript.Element;
import android.renderscript.RenderScript;
import android.renderscript.ScriptIntrinsicBlur;

After that all problems were gone.
