Android :java.lang.SecurityException: Injecting to another application requires INJECT_EVENTS permission

Question

Hi there I am new to Android Junit testing:

I have written some test code in MainActivityFunctionalTest.java file

MainActivityFunctionalTest.java:

Answer 1

I had exactly the same problem and error message when running espresso tests. One of them was always failing when running whole package, however it always passed when I was running it alone. Interesting thing was that the problem happened because I had added following line to one of my Activities in AndroidManifest.xml:

android:windowSoftInputMode="stateUnchanged|adjustResize"

After removing or changing above line to:

android:windowSoftInputMode="stateHidden"

mentioned test was passing also when running whole package.
