Build Android APKs for Revyl’s cloud emulators from Android Studio or the command line.
Revyl’s cloud emulators are x86_64 and the APK must be debuggable. See Artifact Requirements for the full rules and rationale. Default ./gradlew assembleDebug satisfies both — you only need to revisit this if you’ve customized abiFilters or are uploading release builds.

​
Build via Android Studio

​
1. Open Project

Launch Android Studio and open your app.

​
2. Build APK

Choose Build → Build Bundle(s) / APK(s) → Build APK(s)
Use debug builds for Revyl. Release/non-debuggable APKs install but disable the State tab and other debug-only inspection paths.

​
3. Locate Build

Click Locate in the bottom-right notification. APK location: 
app/build/outputs/apk/debug/app-debug.apk

​
4. Upload to Revyl

  1. Go to Builds page
  2. Click Upload Build
  3. Select Android
  4. Drag and drop your .apk
  5. Done!

​
Build via Command Line

# Navigate to project
cd /path/to/your-android-project

# Build debug APK
./gradlew assembleDebug

# Find your APK at:
# app/build/outputs/apk/debug/app-debug.apk

​
Build Variants

# Debug build (recommended for testing)
./gradlew assembleDebug

# Release build
./gradlew assembleRelease

# Specific flavor
./gradlew assembleDemoDebug

​
Authenticated Test States

Revyl launch variables are available to Android emulator apps as launch intent string extras. Use them to gate a test-only myapp://revyl-auth deep link. See Auth Bypass Deep Links for the Kotlin snippet.

Troubleshooting

Revyl’s cloud emulators are x86_64. The APK must include x86_64 in its ABI set. Default debug builds ship all ABIs in one fat APK — only an issue if you’ve narrowed abiFilters.If you need an ABI filter, include x86_64:
android {
    defaultConfig {
        ndk {
            abiFilters 'x86_64', 'arm64-v8a'
        }
    }
}
See Artifact Requirements for details.
Check these locations:
app/build/outputs/apk/debug/app-debug.apk
app/build/outputs/apk/release/app-release.apk
Or search for APK files:
find . -name "*.apk"
Clean and rebuild:
./gradlew clean
./gradlew assembleDebug

# Check dependencies
./gradlew dependencies
Use the wrapper in your project:
# On macOS/Linux
./gradlew assembleDebug

# On Windows
gradlew.bat assembleDebug
If missing, regenerate:
gradle wrapper
Verify the APK contains an x86_64 slice:
aapt dump badging app-debug.apk | grep native-code
# Should include 'x86_64'
If your APK is arm64-v8a-only, rebuild without abiFilters (or with x86_64 included). See Artifact Requirements.
