Or just install the npm package ( authored by a really awesome guy btw ) ) to do that automagically for you: $ npm install -save-dev react-native-build-utils $ convert android/app/src/main/res/mipmap-xxhdpi/ic_launcher.png -shave 12x12 -bordercolor '#EF4142' -border 12 android/app/src/main/res/mipmap-xxhdpi/ic_launcher_dev.png $ convert android/app/src/main/res/mipmap-xhdpi/ic_launcher.png -shave 10x10 -bordercolor '#EF4142' -border 10 android/app/src/main/res/mipmap-xhdpi/ic_launcher_dev.png $ convert android/app/src/main/res/mipmap-hdpi/ic_launcher.png -shave 8x8 -bordercolor '#EF4142' -border 8 android/app/src/main/res/mipmap-hdpi/ic_launcher_dev.png $ convert android/app/src/main/res/mipmap-mdpi/ic_launcher.png -shave 6圆 -bordercolor '#EF4142' -border 6 android/app/src/main/res/mipmap-mdpi/ic_launcher_dev.png If you are running linux, you can use the following commands to auto generate icon versions for your dev app: $ sudo apt-get install imagemagick php5-imagick Let's do that now: Step 3: setting different icon for dev app We could still do better by changing the icon though. On windows you can use photoshop or an image editing tool of your choice for the job. You should now have ic_launcher_dev.png in all the icon folders: Android studio install two versions of same app windows# ROOT/android/app/src/main/res/mipmap-mdpi/ic_launcher_dev.png.ROOT/android/app/src/main/res/mipmap-hdpi/ic_launcher_dev.png.ROOT/android/app/src/main/res/mipmap-xhdpi/ic_launcher_dev.png.ROOT/android/app/src/main/res/mipmap-xxhdpi/ic_launcher_dev.png.Now that we got our dev icons, let's tell our app to use them instead of the production ones. Open ROOT/android/app/src/main/AndroidManifest.xml and probably know what's next. We now have two apps running side by side, and can easily distinguish between them.

So your current configuration is what you should use for development. When it's time to release a new apk, or test production version, you need to reverse all the changes we've just made. It will handle all of those things for you.įull details in the repo, but in short: $ npm run react-native-build-utils icons # generates dev icons based on prod items $ npm install -save-dev react-native-build-utils If that sounds like a lot of work, it's just because it is, that's why I've authored a package to automate the process. Android studio install two versions of same app windows#.Android studio install two versions of same app android#.
