Detox Android Crashing when launching app.

[Osvaldo111]

What happened?

The app is crashing due to an idling issue related to the method "launchApp". In this case, the app is being loaded by Metro, and the app can be seen on the ADB device, the app is being opened and the welcome screen is seen for more than 30 seconds, but then the app crashes when trying to execute the tests.

What was the expected behaviour?

The first test case should be executed without any issue

Was it tested on latest Detox?

• I have tested this issue on the latest Detox release and it still reproduces.

Did your test throw out a timeout?

• I have followed the instructions under Identifying which synchronization mechanism causes us to wait too much.

Help us reproduce this issue!

The error you've described suggests your app remains busy even though the main screen is visible, and therefore the app-launching part, which awaits idle, never resolves.

@Osvaldo111 am facing same issue only on android, iOS working fine
any ideas would be much helpful

@d4vidi adb logs shows
FATAL EXCEPTION: detox.primary Process: com.safarway.app, PID: 32308 java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/test/espresso/IdlingRegistry;

any ideas what to do it has been couple of days that am stuck

[d4vidi]

@FadiAboMsalam You have to reiterate the Android setup guide. Looks like something's slipped away.

[FadiAboMsalam]

@d4vidi just for anyone else facing the issue
turning minifyEnabled & shrinkResources to false made the test work

I am not sure why though

[d4vidi]

@FadiAboMsalam Actually that's not a good advice. Minification is commonly necessary in release-mode apps, and should not be removed altogether. Rather, one should do so while following our ProGuard guide.
