Android crashes on some samsung devices (5.1.1+)

[melihmucuk]

I build an android app and publish on google play, some samsung devices with android 5.1.1+ crash on app start. What is problem with it ? I'm on react-native v0.21.0. I tested with genymotion (4.4.4, 5.1 and 6.0) and I can't notice any issue. I haven't real device for debugging.

Here is my build.gradle:

compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.mobilevo.bikargo"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 3
        versionName "1.0.2"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }

here is my anr reports from google play developer console:

The crash corresponds to a Samsung Galaxy A8 which has 64bit ARM-v8 CPU. Genymotion has a different ABI which is why you don't get any crash. (RISC vs CISC)

A common problem with RN Android was that the native library wasn't generated for all ABIs and you can see more details at #2814. However your trace corresponds to a correctly loaded library which segfaulted during bridge code.

I think you will need to provide a bigger trace and possibly try to reproduce this issue with JNI / NDK debugger.

What other libraries are you using? #1 pc 0017df50 /data/app/com.mobilevo.bikargo-1/lib/arm/librealmreact.so suggests that Realm has something to do with it.

We're pretty sure this is an issue with Realm, and since @melihmucuk filed a corresponding issue with us, I think this can be closed here.
