java.lang.ClassNotFoundException under API Level 19

Question

I have an app, that starts except under API 19 and I get the stacktrace below.

I previously had to add to gradle's build:

defaultConfig {
        multiDexEnabled true

from another similar question I added also the dependency

depenencies {
   ...
   compile 'com.android.support:multidex:1.0.1'
   ...
}

But still the app crashes at start under API19.

Can someone help ?

Answer 1

According to the docs, did you either make you application extend MultiDexApplication or initialize multidex in your application class? Like so:

Either do this:

Make application class extent MultiDexApplication

public class MyApplication extends MultiDexApplication { ... }

Change manifest like so:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
</manifest>

Or this

public class MyApplication extends SomeOtherApplication {
  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(context);
     Multidex.install(this);
  }
}
