React Native Android Build Issues 15.9.0+

[enchorb]

Current Behavior

Android apps have weird build issues on versions above 15.8.9.

First the variant/mode is ignored, by mode for @nrwl/react-native:run-android is devDebug but for whatever reason on versions above 15.8.9 it defaults to prodDebug which causes the build to fail (expecting a different signing config)

For the sake of testing what would happen if the prodDebug build completed (temp changed the signing config), I am then met with the below error

Not sure if this is due to the react-native-community/cli upgrade in 15.9.0 or some other issue but they do seem related

error isAssetFile is not a function

Issue with the wrong variant still exists.

However have discovered the isAssetFile issue is because metro 0.76.0 removed it https://github.com/facebook/metro/releases. My orgs local version was 0.76.0 whereas I assume Nx is not on that yet so we rolled back to 0.75.1 and it is working fine again

@enchorb - I am having the same issue as you. I tried changing the metro dependencies in my package.json to 0.75.1 per your note above, but I still encountered the same build issue with android. Additionally, I noticed that regardless of the version of metro included in my package.json, when I run nx :start, metro 0.73.9 is what starts. I've tried adding metro 0.75.1 in the resolutions section of my package.json, which does cause metro 0.75.1 to start rather than 0.73.9, but android still fails. Any suggestions?

i think maybe downgrade metro to 0.73.9 since it is the react native peer deps version

The variant/mode is ignored from RN CLI's run-android in version 10.2.0, that is declared as dependency of react-native 0.71.7, when using the --list-devices or --deviceId <string>.

Until a version bump of CLI or stable release of 0.72 (which uses version 12.0.0 of react-native CLI), a fix would be to set the run-android executor option "listDevices": false and let the CLI choose the emulator to launch.

I pointed the issue here facebook/react-native#37110 and it the 0.71.8 thread
