浓缩咖啡测试中的“无法启动活动”

Question

Here is my full code , when I test following code with "Android Tests", it raise error "Could not launch activity"

//TestPlayer.kt
public class PlayerTest : ActivityInstrumentationTestCase2<Player>(Player::class.java) {
    override fun setUp() {
        super.setUp()
        getActivity()
    }

    fun testPlayer() {
        onView(withId(R.id.player)).perform(doubleClick())
    }
}

I doesn't find any output in android monitor, how to debug it?

Answer 1

You need to declare Player activity in AndroidManifest.xml like so:

<activity
    android:name=".Player"
    android:theme="@style/AppTheme.NoActionBar">
</activity>
