Windows (PowerShell / CMD):

# Universal fat APK:
.\gradlew.bat :TMessagesProj_AppStandalone:assembleAfatDebug
# 64-bit ARM APK:
.\gradlew.bat :TMessagesProj_AppStandalone:assembleArm64Debug
# 32-bit ARM APK:
.\gradlew.bat :TMessagesProj_AppStandalone:assembleArmv7Debug
# Build all variants simultaneously:
.\gradlew.bat :TMessagesProj_AppStandalone:assembleDebug

Linux / macOS:

chmod +x gradlew
# Universal fat APK:
./gradlew :TMessagesProj_AppStandalone:assembleAfatDebug
# 64-bit ARM APK:
./gradlew :TMessagesProj_AppStandalone:assembleArm64Debug
# 32-bit ARM APK:
./gradlew :TMessagesProj_AppStandalone:assembleArmv7Debug
# Build all variants simultaneously:
./gradlew :TMessagesProj_AppStandalone:assembleDebug

Output APK files will be generated under: TMessagesProj_AppStandalone/build/outputs/apk/

• afat/debug/app-afatDebug.apk (Universal)
• arm64/debug/app-arm64Debug.apk (ARM 64-bit)
• armv7/debug/app-armv7Debug.apk (ARM 32-bit)

./gradlew :TMessagesProj_AppStandalone:assembleAfatRelease \
  -Pandroid.injected.signing.store.file=/path/to/keystore.jks \
  -Pandroid.injected.signing.store.password=YOUR_PASSWORD \
  -Pandroid.injected.signing.key.alias=YOUR_ALIAS \
