Summary:

Super annoying issue:

yarn android --active-arch-only --port 8081
# ^^^ fails with `INSTALL_FAILED_VERSION_DOWNGRADE` if the installed app has a newer version

yarn android --active-arch-only --port 8081 --device emulator-5554
# but if you add `--device` param 💥 NO ERROR at all

Using a --device param force using a CLI (that has -d for adb install ... cmd), see: https://github.com/react-native-community/cli/blob/f4c4ef37ccf98e0205d4a8bc5d9f40f24f1120fd/packages/cli-platform-android/src/commands/runAndroid/tryInstallAppOnDevice.ts#L52

Without--device the app:installDebug task will be used to install an app on all connected devices

Changelog:

[ANDROID] [ADDED] - Allow version code downgrade during run-android

Test Plan:

// 1. New App
npx @react-native-community/cli init --pm yarn --version 0.88.0-rc.6  RN88downgrade
cd RN88downgrade
// 2. Edit `android/app/build.gradle`
// android {
//  defaultConfig {
//        versionCode 999 // <-bump it
//        versionName "9.9.9"

// 3. Run
yarn android --active-arch-only --port 8081
// No error

// 4. Edit one more time `android/app/build.gradle`
//        versionCode 888 // <-lower it
//        versionName "8.8.8"

// 5. Ran again
yarn android --active-arch-only --port 8081
// Error: `INSTALL_FAILED_VERSION_DOWNGRADE`

// 6. Edit one more time `android/app/build.gradle` 
// android {
//    installation {
//        installOptions.add("-d") // <- ADD THIS
//    }


// 7. Ran again
yarn android --active-arch-only --port 8081
// 💥 NO ERROR!

@cortinico Could you please review this pr

[retyui]

@cortinico Do you need anything else from my side to move forward with this PR?

[cortinico]

This change should not go inside the template. Instead it should be added in the run-android command inside the React Native Community CLI here https://github.com/react-native-community/cli

[retyui]

Unfortunately no CLI code is used during run-android (for all devices) (for single device run the CLI have a fix already)

So, I created this PR: react/react-native#59796

Oh so the problem is for all devices only?

"all devices" - meant to run the run-android cmd without --device arg.
So only ./gradlew app:installDebug will be exec

I didn't know how to pass a -d argument thought that cmd

but I hope this will help: react-native-community/cli#2882
