Activity Class {rcm.samapp/com.comp.android.ui....} Does Not Exist

I am trying to integrate react native and native android app. applicationId in apps build.gradle is rcm.samapp package in manifest tag is com.comp.android. Line 1 in SplashActivity

Solution 1:

You have some custom build variants with applicationIdSuffix which are changing package name. You should set them as well in your run-android command.

As far I understood, you need to run development variant. So set --variant development. applicationIdSuffix in development variant is .debug. Specify it as --appIdSuffix debug.

The full command for development variant would be: react-native run-android --appId rcm.samapp --main-activity ui.SplashActivity --variant development --appIdSuffix debug
