Ok I found the problem, the error occurs only when the activity extends
FragmentActivity from the support library. The tests works well when the
activity extends Activity.
It's an old problem of classpath conflict, I found a SO question on it [1],
the fix is to exclude the support library from the test app.
>From the gradle pov, it means adding this :
configurations {
androidTestCompile.exclude group: 'com.android.support', module:
'support-v4'
}
