Having experienced these ClassCastExceptions before, I'd suggest that you check that you do not have a same id being shared by different widgets. Also, check with layouts in different layout-qualifiers folders for the same condition.

Android Navigation Drawer with Page Sliding tab Strip

I'm trying to use Android Navigation Drawer with Page (Pager) Sliding tab Strip (https://github.com/Balaji-K13/Navigation-drawer-page-sliding-tab-strip), but i couldn't make it work. I'm using android studio. I made the imports in main project, and doesn't show any error, but when i run into a device (virtual or real) get this error:

So, thoughts?

I was also trying to implement it and got the same error .After lot of effort I was able to run it but received the similar error as you have received .
I resolved the issue by
1:Close and start your eclipse .
2: copying the v4 jar of main project in all the library projects and deleting the existing ones .
The error comes due to mismatch of supportv4jar. Make all the supportv4jar of same version
3:after that Delete the gen and bin folder and clean the project and run .

Android ClassNotFoundException for Support v7 TestActivity

I have an app that I just received a crash report for. I don't have the full stack trace with me right now, but it was from ActivityLoader.performLaunchActivity.
The class it is trying to launch is android.support.v7.widget.TestActivity. I certainly never try to load this activity anywhere in my app.
The device is a Samsung Galaxy Nexus running 4.1.1 rooted. The stacktrace looked normal to me (no xposed or anything like that).
Anyone ever see anything like this?
EDIT: Here's the stacktrace

After posting this in the Android issue tracker, I've gotten a response saying that it was an issue with Gradle that has been resolved, and will be reflected in the support libraries when they're updated.

This morning I have received from my BugTracker system the same exception in few seconds for several devices
Google Nexus 5 with Android 4.4.2
Galaxy Nexus with Android 4.1.1
Looks like someone have extracted the APK and installed in some simulator (I suspect this also because the reported screen size is 480x800 that is not a screen size of nexus 5.
So I think that this is not a real exception (or at least an exception thrown by our application) but some test made by someone.
The exception received is

Does anyone know how to deal with this?

Custom Application class in Dagger using ActivityIntrumentationTestCase2

I'm stuck trying to "inject" my custom Application to an ActivityInstrumentationTestCase2.
To be able to make unit tests and injections my Application implements an interface like this:
public interface DaggerGraphInjection {
public ObjectGraph getObjectGraph();
}
In the activity i get the graph using:
DaggerGraphInjection injector = (DaggerGraphInjection) getApplication();
injector.getObjectGraph().inject(this);
Using this kind of interface i'm able to inject mock dependencies in my unit tests. But when i want to run functional tests i get the next exception:

That is because, this kind of tests injects the default Application without implements my interface and my question is: Is the any possible solution to this like a custom TestRunner or something like that?
Thank you :)
