Intents never fire using new GoogleApiClient ActivityRecognition

Question

Hav been trying to manually port the sample from http://developer.android.com/training/location/activity-recognition.html to the new GoogleApiClient.

Unfortunately I only got 1 update from the ActivityRecognition sometimes, most times none.

As an attempt to locate the problem I boiled the code down to as few lines as possible. No checks for Google Play Services and no error handling:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Set the main layout
    setContentView(R.layout.activity_main);


    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(ActivityRecognition.API)
            .addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
                @Override
                public void onConnected(Bundle bundle) {
                    Log.d("ActivityRecognition", "Google Play Services connected");
                    Intent i = new Intent(MainActivity.this, ActivityRecognitionIntentService.class);
                    PendingIntent mActivityRecognitionPendingIntent = PendingIntent.getService(MainActivity.this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
                    ActivityRecognition.ActivityRecognitionApi.
                            requestActivityUpdates(mGoogleApiClient, 1000, mActivityRecognitionPendingIntent);
                }

                @Override
                public void onConnectionSuspended(int i) {

                }
            })
            .build();

    mGoogleApiClient.connect();

}

The ActivityRecognitionIntentService has all the code from the sample, but have added a log to the start of onHandleIntent in the hopes to see 'something' happen.

public class ActivityRecognitionIntentService extends IntentService {

    ...

    /**
     * Called when a new activity detection update is available.
     */
    @Override
    protected void onHandleIntent(Intent intent) {

        Log.d("ActivityRecognitionIntentService", "onHandleIntent " + ActivityRecognitionResult.hasResult(intent));

       ...

    }
}

And finally the manifest:

    <uses-sdk android:minSdkVersion="19" android:targetSdkVersion="21" />
    <uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION"/>

    <application android:label="@string/app_name"
        android:icon="@drawable/ic_launcher"
        android:theme="@style/Theme.Sample">

        <activity android:name=".MainActivity"
            android:label="@string/app_name"
            android:uiOptions="splitActionBarWhenNarrow" android:description="@string/app_description">

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <service android:name=".ActivityRecognitionIntentService"></service>

    </application>

</manifest>

Any ideas to what I am doing wrong is appreciated.

Seems if the problem had to do with the construction of PendingIntent

PendingIntent.getService(MainActivity.this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);

If I change that code to:

PendingIntent.getService(MainActivity.this, (int)Math.random(), i, PendingIntent.FLAG_UPDATE_CURRENT);

The intents started firering.

From the documentation on getService() about the second parameter:

requestCode Private request code for the sender

So is no obvious reason for this parameter to have any influence on wheter or not the intent is fired.

Adding Math.Random doesn't solve the problem for me.

In my case, I forgot to add the Service to the AndroidManifest. See: https://stackoverflow.com/a/29726050/1143263
