Detox Detox can't seem to connect to the test app on android.

What happened?

i configured same as detox document for android, it run on ios perfectly but not on android. In android, detox is not able to connect.

DetoxTest.java ---->

             package <packagename>;                  
              import com.wix.detox.Detox;

                  @Rule
                  public ActivityTestRule<MainApplication> mActivityRule = new ActivityTestRule<>(MainApplication.class, false, false);
              
                  @Test
                  public void runDetoxTests() {
                      DetoxConfig detoxConfig = new DetoxConfig();
                      detoxConfig.idlePolicyConfig.masterTimeoutSec = 90;
                      detoxConfig.idlePolicyConfig.idleResourceTimeoutSec = 60;
                      detoxConfig.rnContextLoadTimeoutSec = (BuildConfig.DEBUG ? 180 : 60);
              
                      Detox.runTests(mActivityRule, detoxConfig);
                  }
              }

starter.test.js ------>

                    describe('Login flow', () => {
                      beforeAll(async () => {
                        await device.launchApp();
                      });
                    
                      it('should login successfully', async () => {
                        await expect(element(by.id('login'))).toBeVisible();
                        await expect(element(by.id('username'))).toBeVisible();
                        await element(by.id('username')).typeText('tester');
                        await expect(element(by.id('password'))).toBeVisible();
                        await element(by.id('password')).typeText('password');
                        await element(by.id('signIn')).tap();
                      });
                    });
                    
                    describe('Home flow', () => {
                      it('home screen', async () => {
                        await expect(element(by.id('welcome'))).toBeVisible();
                        await element(by.id('viewHistory')).tap();
                        await element(by.id('historyBackArrow')).tap();
                        await element(by.id('settingsBottomIcon')).tap();
                      });
                    });
                    
                    describe('Settings flow', () => {
                      it('settings screen', async () => {
                        await element(by.id('signOut')).tap();
                      });
                    });

What was the expected behaviour?

The test should have run on android.

Was it tested on latest Detox?

[X] I have tested this issue on the latest Detox release and it still reproduces.

Did your test throw out a timeout?

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

Help us reproduce this issue!

I followed the detox document for the setup and for writing tests, nothing extraordinary.

In what environment did this happen?

Detox version: 20.1.5 React Native version: 0.70.6 Has Fabric (React Native's new rendering system) enabled: (yes/no) no Node version: 16.18.1 Device model: Android version: 11.0.11 Test-runner : jest

still happens on Detox 20.9

By any chances, did you managed to fix it ? Got the same issue. With this kind of specific logs :

artifacts-manager onLaunchApp
19:58:03.366 detox[41625] i child-process:SPAWN_STDOUT INSTRUMENTATION_RESULT: shortMsg=Process crashed.
INSTRUMENTATION_CODE: 0

device An error occurred while waiting for the app to become ready. Waiting for disconnection...
  error: Failed to run application on the device
  
  HINT: Most likely, your tests have timed out and called detox.cleanup() while it was waiting for "ready" message (over WebSocket) from the instrumentation process.
