Question

In my test Project all methods doesn’t have the annotation UiThreadTest, the advantage is that I can perform clicks and anything else and wait then with getInstrumentation().waitForIdleSync(); for the UI. But the disadvantage is that a button in my ui opens a dialog, which calls getActivity() in his constructor – this method returns null, because my test method has not the annotation UIThreadTest, when I add it then the dialog opens, but I can’t use waitForIdleSync.

So is there any equivalent code to wait for the ui with this annotation?

Answer 1

In my experience its good to limit your use of this annotation, what i tend to do is run any code that needs to interact with the Ui thread within a runnable the format is which:

getInstrumentation().runOnMainSync(new Runnable() {
    @Override
    public void run() {
        //code that needs to run on UI thread
    }
}); 

you can then use the waitForIdleSync before and after any actions you do.
