# gRPC-core BinderTransport example apps |
||||
|
||||
## Build Instruction |
||||
|
||||
1. Install Android SDK and NDK. Only NDK version >= 25 is supported. We tested against SDK Platform `33` and NDK `26.2.11394342`. |
||||
2. Make sure Bazel is at least `7.0`. Use `export OVERRIDE_BAZEL_VERSION=7.3.1` to selected a supported version listed in `bazel/supported_versions.txt` if necessary. |
||||
3. Point environment variables to install locations of SDK and NDK |
||||
``` |
||||
export ANDROID_HOME=$HOME/android-sdk |
||||
export ANDROID_NDK_HOME=$HOME/android-sdk/ndk/26.2.11394342 |
||||
``` |
||||
4. To build a fat APK that supports `x86_64`, `armv7`, and `arm64`: |
||||
``` |
||||
bazel build \ |
||||
--extra_toolchains=@androidndk//:all \ |
||||
--android_platforms=//bazel/platforms/android:x86_64,//bazel/platforms/android:armeabi-v7a,//bazel/platforms/android:arm64-v8a \ |
||||
--copt=-Wno-unknown-warning-option \ |
||||
//examples/android/binder/java/io/grpc/binder/cpp/exampleserver:app \ |
||||
//examples/android/binder/java/io/grpc/binder/cpp/exampleclient:app |
||||
``` |
||||
5. `adb install |
||||
bazel-bin/examples/android/binder/java/io/grpc/binder/cpp/exampleclient/app.apk` |
||||
6. `adb install |
||||
bazel-bin/examples/android/binder/java/io/grpc/binder/cpp/exampleserver/app.apk` |
