To tell the Android Wear Watch Face my complication data has been updated, I need to use the ProviderUpdateRequester() method, but it needs a ComponentName. Which is the right component name to use?
I am building a data provider for the Complications feature in Android Wear 2.0 (complications go in Watch Faces).
You can provide an update period to the system via the manifest, but I want to only update the data when there is new data.
It states in the documentation, "You can alternatively use a "push style" to send updates, rather than requesting updates on a fixed schedule. To do so, you can set the update period to 0 so scheduled update requests do not occur (or set it to a non-zero value) and use a ProviderUpdateRequester to trigger calls to onComplicationUpdate as required.".
However, it does not give a snippet of the correct ComponentName to use. I have tried this with no luck:
Here is the code you need:
ComponentName componentName = new ComponentName(getApplicationContext(), MyService.class);
I actually wrote a sample that demonstrates how to do this on GitHub here.
The class the does the work is UpdateComplicationDataService.java class.
Here is the full code excerpt if interested:
ComponentName componentName = new ComponentName(getApplicationContext(), MyService.class); ProviderUpdateRequester providerUpdateRequester = new ProviderUpdateRequester(getApplicationContext(), componentName); // This method only updates the specific complication id, you could // update all with providerUpdateRequester.requestUpdateAll(). providerUpdateRequester.requestUpdate(complicationId);
