I have a project with some unit tests that extends ActivityUnitTestCase, but when I installed the android-support-v7-appcomapt project library to use the ActionBar, these tests have stopped working. I also have some ActivityInstrumentationTestCase2 tests and they are working fine. This is my setup
protected void setUp() throws Exception {
super.setUp();
Intent intent = new Intent(getInstrumentation().getTargetContext(), MyActivity.class);
startActivity(intent, null, null); // The exception happens here
veActivity = getActivity();
//getInstrumentation().callActivityOnStart(veActivity);
}
If I don't call startActivity, veActivity is null.

I tried many suggestions found here in StackOverflow and most of them lead me to this exception.
android.content.pm.PackageManager$NameNotFoundException: ComponentInfo{mypackage/mypackage.MyActivity}
Created a workaround using launchActivity and making sure activities launched are finished. Set the theme manually, launch the activity waiting for idle Sync, and after your tests, finish the activity.
Context context = getInstrumentation().getTargetContext();
context.setTheme(R.style.Theme_AppCompat);
mActivity = launchActivity(context.getPackageName(),
MyActivity.class, null);
getInstrumentation().waitForIdleSync();
// YOUR TESTS
// assertNotNull("The activity cannot be null.", mActivity);
sendKeys(KeyEvent.KEYCODE_BACK);
mActivity.finish();
I think your mistake is :
startActivity(intent, null, null); // The exception happens here
You must use :
setActivityIntent(intent);
You don't need to specify than you start your activity, it will be done automatically.
