protected void launchBrowser(int id)
{
    Uri uri = Uri.parse( getStrin

For some reason you need to set the shadow packagemanager manually on your application. Create a custom test runner (by extending RobolectricTestRunner) and override the setApplicationState method:

public class MyTestRunner extends RobolectricTestRunner {   
  @Override
  public void setupApplicationstate(RobolectricConfig robolectricConfig) {
     super.setupApplicationState(robolectricConfig);
     ShadowApplication shadowApplication = shadowOf(Robolectric.application);
     shadowApplication.setPackageName(robolectricConfig.getPackageName());
     shadowApplication.setPackageManager(new RobolectricPackageManager(Robolectric.application, robolectricConfig));
  }
}

Then specify in your tests that you want to use your own test runner:

@RunWith(MyTestRunner.class)
public class MyTest { ... }
