Multiple flavors in Android project: no way to specify which APK to run after build

Did you verify this is a real problem by searching the NativeScript Forum and the other open issues in this repo?

yes.

Tell us about the problem

When specifying multiple flavors in the app.gradle and thus more than one APK gets generated during build, the CLI prints a warning More than one .apk found in ... directory. Using the last one produced from build.

So depending on Gradle's internal workings when doing a tns run android the APK that was built first is picked. Which may not be the right one in this case.

Would be great if the CLI would have an option to specify which flavor (or APK) to be used on tns run

Which platform(s) does your issue occur on?

macOS, Android build

Please provide the following version numbers that your issue occurs with:

• CLI: 4.0.0
• Cross-platform modules: tns-core-modules 4.0.1
• Runtime(s): tns-androd 4.0.1

lib/services/platform-service.ts の、リンクされている APK 選択ロジックの周辺から始め、tns run android が app.gradle の flavor から生成された複数の APK をどのように扱うかを確認します。CLI オプションと、flavor または APK の選択に関して期待される動作を定義し、そのうえで tns run android がビルド順に依存せず、要求された APK を一貫して起動することを検証します。
