runOnUiThread

void runOnUiThread (Runnable runnable)

Helper for running portions of a test on the UI thread.

Note, in most cases it is simpler to annotate the test method with UiThreadTest, which will run the entire test method including methods annotated with Before and After on the UI thread.

Use this method if you need to switch in and out of the UI thread to perform your test.

Parameters
runnable Runnable: runnable containing test code in the run() method
Throws
Throwable
