Espresso --> Java.lang.SecurityException: test fails due to Package does not belong to <process>

Question

I have an Android Espresso code that attempts to click a button and it fails with a security error.

This is the Espresso command:

Espresso.onData(Matchers.allOf(Matchers.is(Matchers.instanceOf(Preference.class)), withKey(PreferenceKey.pref_custom_server_base_url.toString()), withSummaryText(Configurations.DEFAULT_SERVER_URL))).check(matches(isCompletelyDisplayed()));

This is the error I am receiving:

Any idea why this may happen? Thanks! The code runs on Emulators and Cloud devices with the same error.

I found a solution to the problem in the answer of this stackoverflow question: java.lang.SecurityException: Permission Denial: getIntentSender() when using UiAutomation in a test

When specifying the location of the database, use getTargetContext() instead of getContext() i.e.

File dbFolder = InstrumentationRegistry.getInstrumentation().getTargetContext().getExternalCacheDir();

instead of

File dbFolder = InstrumentationRegistry.getInstrumentation().getContext().getExternalCacheDir();
