gRPC on Android |
||||||
|
============== |
||||||
|
|
||||||
|
Note: Building the protobuf dependency for Android requires |
||||||
|
https://github.com/google/protobuf/pull/3878. This fix will be in the next |
||||||
|
protobuf release, but until then must be manually patched in to |
||||||
|
`third_party/protobuf` to build gRPC for Android. |
||||||
|
|
||||||
|
PREREQUISITES |
||||||
|
------------- |
||||||
|
|
||||||
|
- Android SDK |
||||||
|
- Android NDK |
||||||
|
- `protoc` and `grpc_cpp_plugin` binaries on the host system |
||||||
|
|
||||||
|
INSTALL |
||||||
|
------- |
||||||
|
|
||||||
|
The example application can be built via Android Studio or on the command line |
||||||
|
using `gradle`: |
||||||
|
|
||||||
|
```sh |
||||||
|
$ ./gradlew installDebug |
||||||
|
``` |
