Android app crashes with SIG 9

Question

I know, usually you would tell me to check the logs (before the crash, and see if I missed something) . . Nothing, because the app crashes no matter what, when I try to start a new activity. The only two activities that works are SplashScreen and SignIn

For the sake of trying to find out the problem to this, I did something simple

public class SplashScreen extends AppCompatActivity{
private final static String TAG = SplashScreen.class.getSimpleName();
private final static int DELAY = 2000;

@Override
protected void onCreate(@Nullable final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_screen);

    startActivity(new Intent(this, Root.class));
    finish();
}

and Root.class

public class Root extends AppCompatActivity {
private final static String TAG = Root.class.getSimpleName();
private long backPressedTime = 0;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    Log.i(TAG, "onCreate");
    super.onCreate(savedInstanceState);
    Log.i(TAG, "super.onCreate");
    setContentView(R.layout.trending);
    Log.i(TAG, "setContentView");
}

So I set up some logs and looks like I goes to the second log.. 3rd one setcontentView is not displayed in console. The problem is even more weird, because no matter what class I try to start, it happens the same.

Mentions:

• checked logs, nothing there with an exception (a warning 03-13 13:52:33.302 23233-23233/com.example.codkom.shirtex W/art: Failed execv(/system/bin/dex2oat --runtime-arg -classpath --runtime-arg --debuggable ...

• worked on the app a couple of days and tested on my personal device (working without problems, even now it does) but not on any other devices..

• if does count, I use multidex, I override my Application class and did Multidex.install(context); as per documentation (said this because I had a guess that might be cause by Multidex but tested on API 21+ without multidex and it was ok(since API 21+ handle multidex on it's own)

• I have 7 activities in my project, problem occurs on 3 of them

I got to a point where I have no idea what else to do.. so that's why I came here with this question.

Answer 1

It's Seems, You are using vector Drawables for Images. Vector Drawables doesnot have support below 5.0. To make support vector drawables in below 5.0 and all devices follow the steps.

Step 1:

First you have to mention in gradle. provide the support library

implementation 'com.android.support:appcompat-v7:23.2.0'

enable Vecor Drawable Support

android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
   }  
}

Step 2:

In design XML, when directly using ImageViews should use srcCompat instead of src for Vector Drawables.

<ImageView
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  app:srcCompat="@drawable/ic_add" />

When using it in supporting drawable of components like leftDrawable, rightDrawable of Views, you should wrap the vector in drawable.

ic_action_wrapped.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_action_search_vector"/>
</selector>

Step 3: When you're loading the vector image in runtime, you have to load the image like that.

AppCompatResources.getDrawable(mContext,R.drawable.ic_action_search_vector);

For Some Devices in Application class or your Activity.

static {
        AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
    }

In Your Case Based on log, Toolbar or FloatingActionButton having vector image change and check that.

Google Documenation : official android docs

Stack Overflow also having many reference for vector drawables.

Hope it helps.
