java.lang.RuntimeException: Unable to start activity ComponentInfo when using admob sdk

Question

I'm pretty sure this is nothing about the Theme.AppCompat, because the proguard-enabled app was originally works well without com.google.android.gms:play-services-ads:7.5.0, things went wrong after added com.google.android.gms:play-services-ads:7.5.0.

With com.google.android.gms:play-services-ads included, it only works when proguard disabled.

Can someone please help? I really hate java's inability in protecting source code and wish I could never use proguard.

-keepnames class * implements android.os.Parcelable {

@justDroid sorry I didn't give enough define about @sylte/AppTheme, information updated. I did use Theme.AppCompat.Light.DarkActionBar, isn't it kind of Theme.AppCompat? — Alston
in your manifest you have applied different theme to all activities. try removing that — justDroid
@justDroid The most weirded thing is if I disable proguard, everything works fine. — Alston

The following is what you need in your proguard rules for admob:

-keep class com.google.android.gms.common.GooglePlayServicesUtil {*;}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient {*;}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient$Info {*;}

-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**
-keep class com.google.ads.** {*;}

Check if any is missing or just add all (no difference) and then check if your app works fine.

Also, which class is your Activity java file extending, if it is extending ActionBarActivity, change it to just Activity.
