MediaPipe Android Solution APIs (currently in alpha) are available in:

• MediaPipe Face Detection
• MediaPipe Face Mesh
• MediaPipe Hands

Incorporation in Android Studio

Prebuilt packages of Android Solution APIs can be found in Google's Maven Repository. To incorporate them into an Android Studio project, add the following into the project's Gradle dependencies:

dependencies {
    // MediaPipe solution-core is the foundation of any MediaPipe Solutions.
    implementation 'com.google.mediapipe:solution-core:latest.release'
    // Optional: MediaPipe Face Detection Solution.
    implementation 'com.google.mediapipe:facedetection:latest.release'
    // Optional: MediaPipe Face Mesh Solution.
    implementation 'com.google.mediapipe:facemesh:latest.release'
    // Optional: MediaPipe Hands Solution.
    implementation 'com.google.mediapipe:hands:latest.release'
    // MediaPipe deps
    implementation 'com.google.flogger:flogger:0.6'
    implementation 'com.google.flogger:flogger-system-backend:0.6'
    implementation 'com.google.guava:guava:27.0.1-android'
    implementation 'com.google.protobuf:protobuf-java:3.11.4'
    // CameraX core library
    def camerax_version = "1.0.0-beta10"
    implementation "androidx.camera:camera-core:$camerax_version"
    implementation "androidx.camera:camera-camera2:$camerax_version"
    implementation "androidx.camera:camera-lifecycle:$camerax_version"
}

If you need further customization, instead of using the prebuilt maven packages consider building a MediaPipe Android Archive library locally from source by following these instructions.

Building solution example apps

Detailed usage examples of the Android Solution APIs can be found in the source code of the solution example apps.

To build these apps:

1. Open Android Studio Arctic Fox on Linux, macOS, or Windows.

2. Import mediapipe/examples/android/solutions directory into Android Studio.

   

3. For Windows users, run create_win_symlinks.bat as administrator to create res directory symlinks.

   

4. Select "File" -> "Sync Project with Gradle Files" to sync project.

5. Run solution example app in Android Studio.

   

6. (Optional) Run solutions on CPU.

   MediaPipe solution example apps run the pipeline and model inference on GPU by default. If needed, for example to run the apps on Android Emulator, set the RUN_ON_GPU boolean variable to false in the app's MainActivity.java to run the pipeline and model inference on CPU.
