i am working with Recognizing the User's Current Activity from http://developer.android.com/training/location/activity-recognition.html
i used folow code to create new ActivityRecognitionClient:
public class GPSLocationService extends Service implements ConnectionCallbacks, OnConnectionFailedListener {
private String TAG = "[ServiceDetect]";
//
private ActivityRecognitionClient mActivityRecognitionClient ;
private PendingIntent mPendingIntent ;
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
if (checkGooglePlayAvaible()) {
startTrack();
}
return START_STICKY;
}
#Override
public void onConnected(Bundle bundle) {
// TODO Auto-generated method stub
// code detetc user acitivity here
getActivityRecognitionClient().requestActivityUpdates((2 * 60 * 1000), createPendingRequest());
}
#Override
public void onDisconnected() {
// TODO Auto-generated method stub
mActivityRecognitionClient = null;
mPendingIntent.cancel();
mPendingIntent = null;
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
if (connectionResult.hasResolution()) {
try{
connectionResult.startResolutionForResult((Activity) this.getApplicationContext(), 0);
} catch (IntentSender.SendIntentException e) {
// it happens if the resolution intent has been canceled,
// or is no longer able to execute the request.e
e.printStackTrace();
}
} else {
// Google Play services has no idea how to fix the issue
// it rarely happens for the location service
}
}
public void startTrack() {
try {
if (!getActivityRecognitionClient().isConnected() || !getActivityRecognitionClient().isConnecting() ) {
Log.v(TAG, "getActivityRecognitionClient is not connected");
getActivityRecognitionClient().connect();
}
}
public PendingIntent createPendingRequest() {
if (null != mPendingIntent) {
} else {
Intent intent = new Intent(getApplicationContext(), ServiceFour.class);
mPendingIntent = PendingIntent.getService(getApplicationContext(), 2, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
return mPendingIntent;
}
/**
* check googleplayservices is avaible or not
*
* #return true if is avaible flase if not
*/
public boolean checkGooglePlayAvaible() {
if (GooglePlayServicesUtil.isGooglePlayServicesAvailable(this) == ConnectionResult.SUCCESS) {
return true;
}
return false;
}
#Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mIsRemove = false;
}
private ActivityRecognitionClient getActivityRecognitionClient() {
if (mActivityRecognitionClient == null) {
mActivityRecognitionClient = new ActivityRecognitionClient(getApplicationContext(), this, this);
}
return mActivityRecognitionClient;
}
So with it every 2 min User's Current Activity will be send to service four. in my service four(Intent service) :
#Override
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
if (ActivityRecognitionResult.hasResult(intent)) {
ActivityRecognitionResult result = ActivityRecognitionResult.extractResult(intent);
//
if (result != null) {
//
Log.d("Aha", "he he");
} else {
Log.d("Ohno", "T_T");
}
}
It work fine but when i uninstall app. and install again all ActivityRecognitionResult in servicefour is null it just can be work fine again if i restart device. I don't know how to fix this . Please help me and thanks for reading.
Here is your problem:
E/GooglePlayServicesUtil(18189): The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.
Your GooglePlayServices are not working.
Make sure you included them properly (post your Gradle files etc).
I will post my code for Recognizing the User's Current Activity but with newest api .
public class GPSLocationService extends Service implements ConnectionCallbacks, OnConnectionFailedListener {
private String TAG = "[ServiceDetect]";
//
private PendingIntent mActivityRecognitionPendingIntent;
// Stores the current instantiation of the activity recognition client
private GoogleApiClient mApiClient;
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
if (checkGooglePlayAvaible()) {
startTrack();
}
return START_STICKY;
}
#Override
public void onConnected(Bundle bundle) {
// TODO Auto-generated method stub
// -------------------------------------
// to remove ActivityRecognition call
// ActivityRecognition.ActivityRecognitionApi.removeActivityUpdates
//----------------------------
ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(mApiClient, 2 * 60 * 1000,
createPendingRequest());
//
mApiClient.disconnect();
stopSelf();
}
#Override
public void onConnectionFailed(ConnectionResult arg0) {
// TODO Auto-generated method stub
Log.d(TAG, "onConnectionFailed");
}
#Override
public void onConnectionSuspended(int arg0) {
// TODO Auto-generated method stub
Log.d(TAG, "onConnectionSuspended");
mApiClient.connect();
}
public void startTrack() {
if (mApiClient == null) {
mApiClient = new GoogleApiClient.Builder(getApplicationContext()).addApi(ActivityRecognition.API)
.addConnectionCallbacks(this).addOnConnectionFailedListener(this).build();
}
if (!mApiClient.isConnected() || !mApiClient.isConnecting()) {
mApiClient.connect();
}
}
public PendingIntent createPendingRequest() {
if (null != mActivityRecognitionPendingIntent) {
} else {
Intent intent = new Intent(getApplicationContext(), ServiceFour.class);
mActivityRecognitionPendingIntent = PendingIntent.getService(getApplicationContext(), 2, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
return mActivityRecognitionPendingIntent;
}
public boolean checkGooglePlayAvaible() {
if (GooglePlayServicesUtil.isGooglePlayServicesAvailable(this) == ConnectionResult.SUCCESS) {
return true;
}
return false;
}
#Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
}
}
And now in my servicefour . I receive ActivityRecognitionResult :
#Override
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
Bundle bundle = intent.getExtras();
if (ActivityRecognitionResult.hasResult(intent)) {
if (bundle.containsKey("com.google.android.location.internal.EXTRA_ACTIVITY_RESULT")) {
String activityRecognitionResult = bundle
.getParcelable("com.google.android.location.internal.EXTRA_ACTIVITY_RESULT") + "";
Log.d(TAG, "activityRecognitionResult " + activityRecognitionResult +" (^.,,.^)");
}
}

And permission in Menifest file are
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
You have to save all proximity region IDs(request code) and when u want to remove these region just call to remove from locationmanager . For e.g.
Intent intent = new Intent();
intent.setAction(AppConstants.BROAD_ACTION);
for(int i=0;i<countRegionIDArr.size();i++){
PendingIntent pendingIntent = PendingIntent.getBroadcast(AlertService.this, countRegionIDArr.get(i), intent, 0);
mlocManager.removeProximityAlert(pendingIntent);
}

I am running app using Emulator.Is it possible to run this problem in emulator,because writing to external directory
Can anyone help me?
Use
public DownloadService() {
super("DownloadService");
// TODO Auto-generated constructor stub
}
Instead of
public DownloadService(String name) {
super("DownloadService");
// TODO Auto-generated constructor stub
}
UPDATE:
You have to declare a default constructor which calls the public IntentService (String name) super constructor of the IntentService class you extend. ie. In simple words, you need to provide no-argument constuctor for your service ,without which android wont be able to instantiate your service.
you start the intentservice using startService(your_intent); And as per the documentation
You should not override onStartCommand() method for your
IntentService. Instead, override onHandleIntent(Intent), which the
system calls when the IntentService receives a start request.
IntentService

String unit_id = user.get(SessionManager.KEY_UNITID);
String regu_id = user.get(SessionManager.KEY_REGUID);
JSONObject jsondatagangguan = jmlGangguanFUnctions.getcountdata(
regu_id, unit_id);
try {
Log.d("JUMLAH_GANGGUAN",jsondatagangguan.getString(KEY_JUMLAH_DATA));
JUMLAH_GANGGUAN = jsondatagangguan.getString(KEY_JUMLAH_DATA);
} catch (JSONException e) {
e.printStackTrace();
}
return JUMLAH_GANGGUAN;
}
}
How do I call method getambil_jmlgangguan() in another activity e.g MainActivity and get result of JUMLAH_GANGGUAN periodically.
In my project I have created a widget class, a service and a remote service, however I'm not able to
call the methods for starting or stopping it. I've sample codes here
For widget
Intent intent = new Intent(context, med_service.class);
PendingIntent pi = PendingIntent.getActivity(context, 0, intent, 0);
Toast.makeText(context, pi.toString() + intent.toString(), Toast.LENGTH_SHORT).show();
views.setOnClickPendingIntent(R.id.button1, pi);
Toast.makeText(context, pi.toString() + intent.toString(), Toast.LENGTH_SHORT).show();
for remote service
public class service extends Service implements IBinder{
public IBinder onBind(Intent intent) {
Log.i("RemoteService", "onBind() called");
return new RemoteServiceImpl();
}
/**
* The IRemoteInterface is defined through IDL
*/
public class RemoteServiceImpl extends IRemoteService.Stub {
#Override
public void start() throws RemoteException {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "inside start method", Toast.LENGTH_SHORT).show();
}
#Override
public void stop() throws RemoteException {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "inside stop method", Toast.LENGTH_SHORT).show();
}
}
for service
public class med_service extends Service{
IRemoteService mService;
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
Log.i("RemoteService", "onBind() called");
Toast.makeText(getApplicationContext(), "service not bind to connection", Toast.LENGTH_SHORT).show();
return new service();
}
class RemoteServiceConnection implements ServiceConnection {
public void onServiceConnected(ComponentName className, IBinder service ) {
mService = IRemoteService.Stub.asInterface(service);
}
public void onServiceDisconnected(ComponentName className) {
mService = null;
}
};
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
try{
RemoteServiceConnection mConnection = new RemoteServiceConnection();
getApplicationContext().bindService(new Intent(IRemoteService.class.getName()), mConnection, Context.BIND_AUTO_CREATE);
}
catch(Exception e)
{
Toast.makeText(getApplicationContext(), "service not bind to connection", Toast.LENGTH_SHORT).show();
}
try {
mService.start();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return 1;
}
any kind of help is appreciated
Thank You in advance
use getService instead of getActivity
