Signed APK crashes on android 5.0

I updated an Android project to Android 5.0 and everything is fine when running directly from Eclipse in Genymotion Simulator. But when I create a signed APK and upload that, it crashes. The signed APK works on Android 4.0 Simulator, but not on 5.0. The AppCompat Library is linked with the project in Android > Library.

In the AndroidManifest.xml I have declared:

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="21" />

My base activity extends android.support.v7.app.ActionBarActivity. And this is the error I see in logcat when running on 5.0:

FATAL EXCEPTION: main
Process: com.myapp.mypackage, PID: 1414
     java.lang.AbstractMethodError: abstract method "android.support.v7.app.ActionBar ol.a()"

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:694)

What could cause this or what is the difference between running directly and installing, except the signing?

Thank you very much, your help is appreciated!

  1. Delete Eclipse and install Android Studio. ADT plugin is no longer supported by Google.
  2. You should always target latest Android version (current latest is 22)
  3. You should use latest v7 appcompat library (current latest is 22.2.0)
  4. You should extend your activity from AppCompatActivity

This is an issue with Samsung's custom android and zipalign. While using zipalign, remove the -z parameter. This apk should work.
