gRPC Android test App

Implements gRPC integration tests in an Android App.

TODO(madongfly) integrate this App into the gRPC-Java build system.

In order to build this app, you need a local.properties file under this directory which specifies the location of your android sdk:

sdk.dir=/somepath/somepath/sdk

Connect your Android device or start the emulator:

$ ./start-emulator.sh <AVD name> & ./wait-for-emulator.sh

Manually test

Install the App by:

$ ../gradlew installDebug

Then manually test it with the UI.

Commandline test

Run the test with arguments:

$ adb shell am instrument -w -e server_host <hostname or ip address> -e server_port 8030 -e server_host_override foo.test.google.fr -e use_tls true -e use_test_ca true -e test_case all io.grpc.android.integrationtest/.TesterInstrumentation

If the test passed successfully, it will output:

INSTRUMENTATION_RESULT: grpc test result=Succeed!!!
INSTRUMENTATION_CODE: 0

otherwise, output something like:

INSTRUMENTATION_RESULT: grpc test result=Failed... : <exception stacktrace if applicable>
INSTRUMENTATION_CODE: 1
