java.lang.NoClassDefFoundError: android

Question

I'm developing an app, that should support multiple android sdk versions. It uses the ActionBarSherlock library and sliding menu. On android 4.0+ the app runs just well. But when I try to run it on all of the devices with lower sdk version, the app crashes with strange error. Here is the stack trace:

</application>

I thought, that it was because of the sliding menu. I've tried to use native SlidingPaneLayout, but the issue is the same. I read a lot about this and nothing really helps. Please, help !!!

Answer 1

Thanks everyone, I've found the solution. It was the problem with SearchView. You should use one from ActionBarSherlock or SupportLibrary

Answer 2

This is a pretty elusive problem. You mentioned that it works on Android 4.0+, and that sets off an alarm that you might be using something that's not supported in older versions of Android.

But before all that, if you're using Eclipse, you should refresh your project and do a clean build. Sometimes Eclipse has trouble picking up AndroidManifest changes and you might be loading an older version on your emulator/device.

If it still fails, it might be that you're importing something not supported in older APIs, or perhaps the AvatatorActivity class extends something only available in newer APIs. Can you post some code for your AvatatorActivity (namely, the imports and what AvatatorActivity extends)?

It would also help to know what you set for android:minSdkVersion and android:targetSdkVersion.

======== EDIT ========

Thanks for posting the code. The SlidingFragmentActivity is very suspicious, and chances are this library is missing. The easiest way to debug this would be to save a copy of the current AvatatorActivity.java and replace it with the following to see if you can launch the activity.

public class AvatatorActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setTitle(R.string.app_name);
    }
}

If this bare-bone Activity launches, then there's a problem with your SlidingMenu setup.

Answer 3

Are you using eclipse adt plugin? if so, just right click the project->properties->Java Build apth ->Order and export, then make the Android Dependencies is checked.

EDIT: as you are using Intellij, have you checked if you have imported the SlidingMenu library as a module?

ps. , I am using Android studio & Maven, I think you can just import the project as library if you are not using maven.

Answer 4

StrictMode was introduced in API level 9 (version 2.3) so the older versions you're testing on must not be able to call it...

08-08 11:54:12.346: ERROR/dalvikvm(4782): Could not find class 'android.os.StrictMode$ThreadPolicy$Builder', referenced from method ru.arsenalmedia.proto.Utils.enableStrictMode

When you call your Utils.enableStrictMode() method you should first check if the users device is running a version that has access to StrictMode.

EDIT: Something like this may also be causing a problem; using xml attributes that didn't exist in older platforms in your styles.xml, per this line:

08-08 11:54:11.696: ERROR/ResourceType(4782): Style contains key with bad entry: 0x010102ce

It still doesn't explain your NoClassDefFoundError
