Please follow instructions below to use the MediaPipe Solution APIs in Android
|
||
|
|
Studio projects and build the Android example apps in the supported MediaPipe
|
||
|
|
[solutions](../solutions/solutions.md).
|
||
|
|
|
||
|
|
## Integrate MediaPipe Android Solutions in Android Studio
|
||
|
|
|
||
|
|
MediaPipe Android Solution APIs (currently in alpha) are now available in
|
||
|
|
[Google's Maven Repository](https://maven.google.com/web/index.html?#com.google.mediapipe).
|
||
|
|
To incorporate MediaPipe Android Solutions 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 Hands solution.
|
||
|
|
implementation 'com.google.mediapipe:hands:latest.release'
|
||
|
|
// Optional: MediaPipe FaceMesh solution.
|
||
|
|
implementation 'com.google.mediapipe:facemesh:latest.release'
|
||
|
|
// MediaPipe deps
|
||
|
|
implementation 'com.google.flogger:flogger:latest.release'
|
||
|
|
implementation 'com.google.flogger:flogger-system-backend:latest.release'
|
||
|
|
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"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
See the detailed solutions API usage examples for different use cases in the
|
||
|
|
solution example apps'
|
||
|
|
[source code](https://github.com/google/mediapipe/tree/master/mediapipe/examples/android/solutions).
|
||
|
|
If the prebuilt maven packages are not sufficient, building the MediaPipe
|
||
|
|
Android archive library locally by following these
|
||
|
|
[instructions](./android_archive_library.md).
|
||
|
|
|
||
|
|
## Build solution example apps in Android Studio
|
||
|
|
|
||
|
|
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 the 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 the model inference on CPU.
