Does Android ActivityRecognitionApi work , No Updates received on onHandleIntent

Question

Guys have anybody got the ActivityrecognitionAPI to work in Android. It does not give any updates. Have tried the API documents, Plenty of Examples. OnHandleIntent does not fire.

 import com.google.android.gms.location.ActivityRecognitionResult;
import com.google.android.gms.location.DetectedActivity;

import android.app.IntentService;
import android.content.Intent;
import android.support.v4.content.LocalBroadcastManager;

public class ActivityRecognitionIntentService extends IntentService{

    ActivityRecognitionResult result;
    Intent i;
    DetectedActivity mpactivity;

    public ActivityRecognitionIntentService() {
        super("ActivityRecognitionIntentService");
        i = new Intent("ACTIVITY_RECOGNITION_DATA");
        }

    private String getTypes(int type) {
        if(type == DetectedActivity.UNKNOWN)
            return "Unknown";
        else if(type == DetectedActivity.IN_VEHICLE)
            return "In Vehicle";
        else if(type == DetectedActivity.ON_BICYCLE)
            return "On Bicycle";
        else if(type == DetectedActivity.RUNNING)
            return "Running";
        else if(type == DetectedActivity.ON_FOOT)
            return "On Foot";
        else if(type == DetectedActivity.STILL)
            return "Still";
        else if(type == DetectedActivity.TILTING)
            return "Tilting";
        else if(type == DetectedActivity.WALKING)
            return "Walking";
        else
            return "";
        }

    @Override
    protected void onHandleIntent(Intent intent) {
         if (intent.getAction() == "ActivityRecognitionIntentService") {
            if(ActivityRecognitionResult.hasResult(intent)){    
                result = ActivityRecognitionResult.extractResult(intent);
                mpactivity = result.getMostProbableActivity();
                i.putExtra("Activity", getTypes(mpactivity.getType()));
                i.putExtra("Confidence", mpactivity.getConfidence());
                LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(i);
                }
            }
        }
    }       

The Main activity is as

     import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesClient;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.location.ActivityRecognition;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.content.LocalBroadcastManager;
import android.widget.TextView;
import android.widget.Toast;

public class Actrecogex extends Activity implements GooglePlayServicesClient.ConnectionCallbacks, GooglePlayServicesClient.OnConnectionFailedListener,  GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener{

    TextView textView1;
    GoogleApiClient mGoogleActclient;
    PendingIntent mActivityRecognitionPendingIntent;
    Intent i;
    LocalBroadcastManager mBroadcastManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.actrecogex);

        textView1 = new TextView(this);
        textView1 =(TextView)findViewById(R.id.textView1);   

        i = new Intent(this, ActivityRecognitionIntentService.class);  
        mBroadcastManager = LocalBroadcastManager.getInstance(this);

        mGoogleActclient = new GoogleApiClient.Builder(this)
        .addApi(ActivityRecognition.API)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .build();

        mGoogleActclient.connect();
        }

    @Override
    public void onConnectionFailed(ConnectionResult arg0) {
        textView1.setText("Failed Connection" + arg0); 
        }

    @Override
    public void onConnected(Bundle arg0) {
        i.setAction("ActivityRecognitionIntentService");
        mActivityRecognitionPendingIntent = PendingIntent.getService(this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
        ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(mGoogleActclient, 0, mActivityRecognitionPendingIntent);  
        }

    @Override
    public void onConnectionSuspended(int arg0) {
        textView1.setText("Failed Suspended" + arg0);
        }

    private BroadcastReceiver receiver = new BroadcastReceiver(){
        @Override
        public void onReceive(Context context, Intent intent) {
            Toast.makeText(getApplicationContext(), "Service", Toast.LENGTH_SHORT).show();
            String v =  "Activity :" + intent.getStringExtra("Activity") + " " + "Confidence : " + intent.getExtras().getInt("Confidence") + "\n";
            v += textView1.getText() ;
            textView1.setText(v);
            }
        };

    @Override
    public void onDisconnected() {
        textView1.setText("Disconnected" ); 
        }
    }

Manifest

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="21" />
<uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION"/>

<application

    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".Actrecogex"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>
    <service android:name="ActivityRecognitionIntentService" android:exported="false"></service>
</application>

Does the code really work, Or I am wasting time. Seriously want to go back Activityrecogntionclient. Testing the App on Gingerbread and Kitkat. Both does not budge

Answer 1

 if (intent.getAction() == "ActivityRecognitionIntentService") {
}

Was giving null value. So the periodic Error Message.

The Main Problem was the Broadcastreceiver was not receiving anything. So needed to have separate class for Broadcastreceiver. It is Working now.

<receiver android:name="ActBreceiver" android:exported="false">
            <intent-filter>
                <action android:name="ACTIVITY_RECOGNITION_DATA"/>
            </intent-filter>
        </receiver>
