flavorDimensions "app"
productFlavors { 
 demo {
 dimension "app"
 applicationId "com.demo"
 resValue "string", "app_name", "demo"
 manifestPlaceholders = [
 appIcon: "@mipmap/ic_launcher_demo"
 ]
 versionCode 1
 versionName "1.0"
 }
 full {
 dimension "app"
 applicationId "com.full"

 appIcon: "@mipmap/ic_launcher_full"

 versionCode 1
 versionName "1.0"
 }
}

Expected Behavior

expect different flavors of app will build on android device,

Actual Behavior

the build failed and i, i get this error
Error: Activity class {com.todo/com.todo.MainActivity} does not exist,

but I'm able to build the app successfully if i remove the productFlavors {}

any advice will be appreciate.

Thanks for posting this! It looks like you may not be using the latest version of React Native, v0.53.0, released on January 2018. Can you make sure this issue can still be reproduced in the latest version?

I am going to close this, but please feel free to open a new issue if you are able to confirm that this is still a problem in v0.53.0 or newer.

I'm writing new versions of old apps, and thus I have inherited old app id's.

My code have the package com.common.package (in source files and AndroidManifest.xml).

My build.gradle contains

 buildTypes {
 debug {
 }
 release {
 minifyEnabled enableProguardInReleaseBuilds
 proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
 }
 }

 flavorDimensions "appName"
 productFlavors {
 appAAA {
 dimension "appName"
 applicationId "com.AAA.app"
 versionCode 100
 versionName "3.0.0"
 }
 appBBB {
 dimension "appName"
 applicationId "com.BBB.app"
 versionCode 100
 versionName '3.0.0'
 }
 }

First the app can be installed with gradlew

cd android && ./gradlew installAppBBBDebug

The I can start it manually with

adb -s emulator-5554 shell am start -n com.BBB.app/com.common.package.MainActivity

This is a bloody hassle. I would rather not have to mess with it like this.

I ran into this issue and found some way to make it work:
I have two product flavors

• prod, with applicationId "com.yetno.yetnoapp" (which is the main app id)
• dev, with applicationId "com.yetno.yetno_app"

When building and running dev (react-native run-android --variant=devDebug) I was getting the error described in this issue.
Then I noticed, if I build the prod variant first and have it installed on the device, building and installing the dev variant works fine.
So the steps are:

1. cd android && ./gradlew clean
2. cd ..
3. react-native run-android --variant=prodDebug
4. react-native run-android --variant=devDebug

So this is not really an answer, but it worked for me and maybe it can help some of you guys out :)
