Async Event RPC Example

This example shows you how to use the @AsyncRpc annotation of Mobly snippet lib to handle asynchronous callbacks.

See the source code in ExampleAsyncSnippet.java for details.

Running the example code

This folder contains a fully working example of a standalone snippet apk.

1. Compile the example

   ./gradlew examples:ex3_async_event:assembleDebug
   

2. Install the apk on your phone

   adb install -r ./examples/ex3_async_event/build/outputs/apk/debug/ex3_async_event-debug.apk
   

3. Use snippet_shell from mobly to trigger tryEvent():

   snippet_shell.py com.google.android.mobly.snippet.example3
   
   >>> handler = s.tryEvent(42)
   >>> print("Not blocked, can do stuff here")
   >>> event = handler.waitAndGet('AsyncTaskResult') # Blocks until the event is received
   
   Now let's see the content of the event
   
   >>> import pprint
   >>> pprint.pprint(event)
   {
       'callbackId': '2-1',
       'name': 'AsyncTaskResult',
       'time': 20460228696,
       'data': {
           'exampleData': "Here's a simple event.",
           'successful': True,
           'secretNumber': 12
       }
   }
