Summary:

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

Important

Using a --device param force using a CLI (that has -d for adb install ... cmd), see:

cli/packages/cli-platform-android/src/commands/runAndroid/tryInstallAppOnDevice.ts

Line 52 in f4c4ef3

const installArgs = ['-s', device, 'install', '-r', '-d'];

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

Changelog:

[ANDROID] [CHANGED] - 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 (like -Pandroid.adbOptions.installOptions=-d)
//    }


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