I've developed Android Wear watch face, which gets location within a Service on handheld side. I use AsyncTask code which I've got from here. This error drains about 50% battery of the phone. And I don't know why. Please help. Error:
W/MessageQueue: Handler (android.location.LocationManager$ListenerTransport$1) {93795ca} sending message to a Handler on a dead thread
java.lang.IllegalStateException: Handler (android.location.LocationManager$ListenerTransport$1) {93795ca} sending message to a Handler on a dead thread

And here is the ASyncTask:
private class Task extends AsyncTask
{
private String resp;
@Inject

@Override
protected Object doInBackground( Object[] params )
{
if (this.isCancelled()) {
return null;
}
try
{
Log.d( TAG, "Task Running" );
RoboGuice.getInjector( WeatherService.this.getApplicationContext() ).injectMembers( this );
if ( !mGoogleApiClient.isConnected() )
{ mGoogleApiClient.connect();
}
final DataMap config = new DataMap();
WeatherInfo infoNetwork = api.getCurrentWeatherInfo(latitude, longitude);
config.putInt( KEY_WEATHER_TEMPERATURE, infoNetwork.getTemperature() );
config.putString( KEY_WEATHER_CONDITION, infoNetwork.getCondition() );
config.putLong( KEY_WEATHER_SUNSET, infoNetwork.getSunset() );
config.putLong( KEY_WEATHER_SUNRISE, infoNetwork.getSunrise() );
config.putInt( KEY_WEATHER_WIND_SPEED, infoNetwork.getSpeed() );
config.putInt( KEY_WEATHER_WIND_DEGREE, infoNetwork.getDeg() );
config.putInt( KEY_WEATHER_TEMP_MIN, infoNetwork.getTempMin() );
config.putInt( KEY_WEATHER_TEMP_MAX, infoNetwork.getTempMax() );
config.putInt( KEY_WEATHER_HUMIDITY, infoNetwork.getHumidity() );
config.putInt( KEY_WEATHER_PRESSURE, infoNetwork.getPressure() );
Wearable.MessageApi.sendMessage(mGoogleApiClient, mPeerId, PATH_WEATHER_INFO, config.toByteArray())
.setResultCallback(
new ResultCallback<MessageApi.SendMessageResult>() {
@Override
public void onResult(MessageApi.SendMessageResult sendMessageResult) {
Log.d(TAG, "SendUpdateMessage: " + sendMessageResult.getStatus());
Log.v(TAG, KEY_WEATHER_CONDITION);
Log.v(TAG, "AsyncTask config in onResult: " + config.toString());
Log.v(TAG, "mGoogleApiClient, mPeerId, PATH_WEATHER_INFO, config.toByteArray()" + mGoogleApiClient + " " + mPeerId + " " + PATH_WEATHER_INFO + " " + config);
}
}
);
}catch (IllegalStateException e) {
e.printStackTrace();
resp = e.getMessage();
}
catch ( Exception e )
{
Log.d( TAG, "Task Fail: " + e );
}
return null;
}
}
Please help, I'm a new developer and trying to solve this problem and for now without any result.
