Open my app automatically when in Range of certain location

I am using an intent to switch to Google Maps to get the route to a marker that's shown on a map that's implemented in my app. My question is if there is any way to let my app in background to send the location at certain intervals of time, so when the user gets close to the location, when the app is reopened to have the location updated directly, so I would be able to implement the next step of the app.( the app should do something when he is close)

You can try create and monitor geofence for detect user gets close to the location:
public class MainActivity extends AppCompatActivity {
// ...
private PendingIntent getGeofencePendingIntent() {
// Reuse the PendingIntent if we already have it.
if (geofencePendingIntent != null) {
return geofencePendingIntent;
}
Intent intent = new Intent(this, GeofenceBroadcastReceiver.class);
// We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when
// calling addGeofences() and removeGeofences().
geofencePendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.
FLAG_UPDATE_CURRENT);
return geofencePendingIntent;
}
and then, when user gets close to the location start tracking it directly from your app. Something like that:
public class GeofenceBroadcastReceiver extends BroadcastReceiver {
// ...
protected void onReceive(Context context, Intent intent) {
GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
if (geofencingEvent.hasError()) {
String errorMessage = GeofenceStatusCodes.getErrorString(geofencingEvent.getErrorCode());
Log.e(TAG, errorMessage);
return;
}
// Get the transition type.
int geofenceTransition = geofencingEvent.getGeofenceTransition();
// Test that the reported transition was of interest.
if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER) {
// Get the geofences that were triggered. A single event can trigger
// multiple geofences.
List<Geofence> triggeringGeofences = geofencingEvent.getTriggeringGeofences();
// Get the transition details as a String.
String geofenceTransitionDetails = getGeofenceTransitionDetails(
this,
geofenceTransition,
triggeringGeofences
);
// Start tracking user position directly here
...
} else if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {
// Stop tracking user position directly here
...
else {
// Log the error.
Log.e(TAG, getString(R.string.geofence_transition_invalid_type,
geofenceTransition));
}
}
}

I'm not sure it will work or not but you can try this one. my guess should work.
ActivityManager activityManager = (ActivityManager) getApplicationContext()
.getSystemService(Context.ACTIVITY_SERVICE);
activityManager.moveTaskToFront(getTaskId(), 0);

Please note that you cannot keep to get the user location in the background when the system is greater than or equal to android O

Solution : You can register a Service in the foreground.
Step 1:Create your own service
Step 2:register with Androidmanifest
Step 3:Create BroadcastReceiver receiver data
Step 4:In onResume bind and onstop unbind service

Android Geofence not triggers once location OFF and ON again [duplicate]

This question already has answers here:
How to check if Location Services are enabled?
(23 answers)
Closed 7 years ago.
I am using Android Geofencing API.After add geofence it works fine when location is ON.But If I OFF location and ON again,afterwards Geofencing not triggers when enter or exit.I have tested on my Moto G with Android 5.0.2 device. Is it Geofence will expire If location is off?
I have seen on Android document as,
In case network location provider is disabled by the user, the
geofence service will stop updating, all registered geofences will be
removed and an intent is generated by the provided pending intent. In
this case, the GeofencingEvent created from this intent represents an
error event, where hasError() returns true and getErrorCode() returns
GEOFENCE_NOT_AVAILABLE.
Document link

Yeap, geofences will be removed once location is switched off.
You should listen for location provider broadcasts using a BroadcastReceiver in your manifest, something like:
<receiver android:name="your.Receiver">
<intent-filter>
<action android:name="android.location.PROVIDERS_CHANGED"/>
</intent-filter>
</receiver>
and then register your geofences again.
public class LocationProviderReceiver extends BroadcastReceiver {
public LocationProviderReceiver() {
}
#Override
public void onReceive(Context context, Intent intent) {
if (action.equals(LocationManager.PROVIDERS_CHANGED_ACTION)) {
// if location services enabled
// restart geofences
}
}
}

Add this to the manifest:
<receiver android:name="com.aol.android.geofence.GeofenceReceiver"
android:exported="false">
<intent-filter >
<action android:name="com.aol.android.geofence.ACTION_RECEIVE_GEOFENCE"/>
</intent-filter>
</receiver>
Then in the GeofenceRequester class you need to change the createRequestPendingIntent method so that it goes to your BroadcastReceiver instead of the ReceiveTransitionsIntentService
private PendingIntent createRequestPendingIntent() {
// If the PendingIntent already exists
if (null != mGeofencePendingIntent) {
// Return the existing intent
return mGeofencePendingIntent;
// If no PendingIntent exists
} else {
// Create an Intent pointing to the IntentService
Intent intent = new Intent("com.aol.android.geofence.ACTION_RECEIVE_GEOFENCE");
// Intent intent = new Intent(context, ReceiveTransitionsIntentService.class);
/*
* Return a PendingIntent to start the IntentService.
* Always create a PendingIntent sent to Location Services
* with FLAG_UPDATE_CURRENT, so that sending the PendingIntent
* again updates the original. Otherwise, Location Services
* can't match the PendingIntent to requests made with it.
*/
return PendingIntent.getBroadcast(
context,
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
}
Then I added the GeofenceReceiver class that looks something like this:
public class GeofenceReceiver extends BroadcastReceiver {
Context context;
Intent broadcastIntent = new Intent();
#Override
public void onReceive(Context context, Intent intent) {
this.context = context;
broadcastIntent.addCategory(GeofenceUtils.CATEGORY_LOCATION_SERVICES);
if (LocationClient.hasError(intent)) {
handleError(intent);
} else {
handleEnterExit(intent);
}
}
private void handleError(Intent intent){
// Get the error code
int errorCode = LocationClient.getErrorCode(intent);
// Get the error message
String errorMessage = LocationServiceErrorMessages.getErrorString(
context, errorCode);
// Log the error
Log.e(GeofenceUtils.APPTAG,
context.getString(R.string.geofence_transition_error_detail,
errorMessage));
// Set the action and error message for the broadcast intent
broadcastIntent
.setAction(GeofenceUtils.ACTION_GEOFENCE_ERROR)
.putExtra(GeofenceUtils.EXTRA_GEOFENCE_STATUS, errorMessage);
// Broadcast the error *locally* to other components in this app
LocalBroadcastManager.getInstance(context).sendBroadcast(
broadcastIntent);
}
private void handleEnterExit(Intent intent) {
// Get the type of transition (entry or exit)
int transition = LocationClient.getGeofenceTransition(intent);
// Test that a valid transition was reported
if ((transition == Geofence.GEOFENCE_TRANSITION_ENTER)
|| (transition == Geofence.GEOFENCE_TRANSITION_EXIT)) {
// Post a notification
List<Geofence> geofences = LocationClient
.getTriggeringGeofences(intent);
String[] geofenceIds = new String[geofences.size()];
String ids = TextUtils.join(GeofenceUtils.GEOFENCE_ID_DELIMITER,
geofenceIds);
String transitionType = GeofenceUtils
.getTransitionString(transition);
for (int index = 0; index < geofences.size(); index++) {
Geofence geofence = geofences.get(index);
...do something with the geofence entry or exit. I'm saving them to a local sqlite db
}
// Create an Intent to broadcast to the app

Android Geofence cannot call IntentService and cannot work inside BroadcastReceiver

I have problem when I'm trying to use geofence with my app. I have succeed to register geofence but I have never get the notification.
First I follow the example that provide in http://developer.android.com/training/location/geofencing.html ,but the code never trigger intent service even I'm walking toward or away from area.
My code for register geofence and calling the intent service as follow :
inside manifest :
<service
android:name="com.example.zukami.apps.blynk.geofence.ReceiveTransitionsIntentService"
android:exported="true" >
</service>
in my MainActivity
private boolean registerGeofence() {
mRequestType = GeofenceUtils.REQUEST_TYPE.ADD;
if (!servicesConnected()) {
return false;
}
SimpleGeofence testGeo = new SimpleGeofence(Flag.GEOFENCE + "_"
+ 1, Double.valueOf("1.317342"),
Double.valueOf("103.841998"), (float) (200),
GEOFENCE_EXPIRATION_IN_HOURS,
Geofence.GEOFENCE_TRANSITION_ENTER);
mPrefs.setGeofence(Flag.GEOFENCE + "_" + 1, testGeo);
mCurrentGeofences.add(testGeo.toGeofence());
SimpleGeofence testGeo2 = new SimpleGeofence(Flag.GEOFENCE + "_"
+ 2, Double.valueOf("1.303961"),
Double.valueOf("103.909356"), (float) (200),
GEOFENCE_EXPIRATION_IN_HOURS,
Geofence.GEOFENCE_TRANSITION_ENTER);
mPrefs.setGeofence(Flag.GEOFENCE + "_" + 2, testGeo2);
mCurrentGeofences.add(testGeo2.toGeofence());
// end deleted this code after testing
try {
mGeofenceRequester.addGeofences(mCurrentGeofences);
Log.e(TAG, "ADDING GEOFENCE ??? YES WE DID IT");
} catch (UnsupportedOperationException e) {
Toast.makeText(this,
R.string.add_geofences_already_requested_error,
Toast.LENGTH_LONG).show();
}
return true;
}
#Override
protected void onResume() {
super.onResume();
// Register the broadcast receiver to receive status updates
LocalBroadcastManager.getInstance(this).registerReceiver(mBroadcastReceiver, mIntentFilter);
in my GeofenceRequester
private PendingIntent createRequestPendingIntent() {
Log.e(TAG, "CREATE REQUEST PENDING INTENT");
// If the PendingIntent already exists
if (null != mGeofencePendingIntent) {
Log.e(TAG, "PENDING INTENT NOT NULL");
return mGeofencePendingIntent;
// If no PendingIntent exists
} else {
Log.e(TAG, "PENDING INTENT NULL, LET'S CREATED IT");
// Create an Intent pointing to the IntentService
Intent intent = new Intent(mActivity,
ReceiveTransitionsIntentService.class);
Log.e(TAG,
return PendingIntent.getService(mActivity, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
and in class that subclass from IntentService remain same as an example.
I do search for this problem and found this solutions that describe on this link :
Android Geofence eventually stop getting transition intents ,so I change my code exactly as per suggestion, but still I cannot getting the notification, from my code inside GeofenceReceiver class, the code in this line
LocationClient.getGeofenceTransition(intent);
always return me -1 that means I never enter or leave the area (indicate GEOFENCE NEVER_EXPIRED),so I never get the notification. Please find below my GeofenceReceiver class :
public class GeofenceReceiver extends BroadcastReceiver {
public static String TAG = GeofenceReceiver.class.getCanonicalName();
Context context;
Intent broadcastIntent = new Intent();
#Override
public void onReceive(Context context, Intent intent) {
this.context = context;
broadcastIntent.addCategory(GeofenceUtils.CATEGORY_LOCATION_SERVICES);
if (LocationClient.hasError(intent)) {
handleError(intent);
} else {
handleEnterExit(intent);
}
}
private void handleError(Intent intent) {
int errorCode = LocationClient.getErrorCode(intent);
String errorMessage = LocationServiceErrorMessages.getErrorString(
context, errorCode);
Log.e(GeofenceUtils.APPTAG, context.getString(
R.string.geofence_transition_error_detail, errorMessage));
broadcastIntent.setAction(GeofenceUtils.ACTION_GEOFENCE_ERROR)
.putExtra(GeofenceUtils.EXTRA_GEOFENCE_STATUS, errorMessage);
LocalBroadcastManager.getInstance(context).sendBroadcast(
broadcastIntent);
}
private void handleEnterExit(Intent intent) {
int transition = LocationClient.getGeofenceTransition(intent);
// Test that a valid transition was reported
if ((transition == Geofence.GEOFENCE_TRANSITION_ENTER)
|| (transition == Geofence.GEOFENCE_TRANSITION_EXIT)) {
// Post a notification
List<Geofence> geofences = LocationClient
.getTriggeringGeofences(intent);
String[] geofenceIds = new String[geofences.size()];
String ids = TextUtils.join(GeofenceUtils.GEOFENCE_ID_DELIMITER,
geofenceIds);
String transitionType = getTransitionString(transition);
for (int index = 0; index < geofences.size(); index++) {
Geofence geofence = geofences.get(index);
geofenceIds[index] = geofences.get(index).getRequestId();
}
sendNotification(transitionType, ids);
// Create an Intent to broadcast to the app
broadcastIntent
.setAction(GeofenceUtils.ACTION_GEOFENCE_TRANSITION)
.addCategory(GeofenceUtils.CATEGORY_LOCATION_SERVICES)
.putExtra(GeofenceUtils.EXTRA_GEOFENCE_ID, geofenceIds)
.putExtra(GeofenceUtils.EXTRA_GEOFENCE_TRANSITION_TYPE,
transitionType);
LocalBroadcastManager.getInstance(context).sendBroadcast(
broadcastIntent);
// Log the transition type and a message
Log.e(GeofenceUtils.APPTAG, transitionType + ": " + ids);
Log.e(GeofenceUtils.APPTAG, context
.getString(R.string.geofence_transition_notification_text));
Log.e(GeofenceUtils.APPTAG, "transition");
} else {
// Always log as an error
Log.e(TAG, "TRANSITION = " + transition);
}
}
Kindly advise what should I do for fix this code and really appreciate for any kind help.

for me I just changed some lines of code in createPendingIntent method
private PendingIntent createRequestPendingIntent() {
Log.e(TAG, "CREATE REQUEST PENDING INTENT");
// If the PendingIntent already exists
if (null != mGeofencePendingIntent) {
Log.e(TAG, "PENDING INTENT NOT NULL");
return mGeofencePendingIntent;
// If no PendingIntent exists
} else {
Log.e(TAG, "PENDING INTENT NULL, LET'S CREATED IT");
// Create an Intent pointing to the IntentService
Intent intent = new Intent(mActivity,
ReceiveTransitionsIntentService.class);
Log.e(TAG,
return PendingIntent.getService(mActivity, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
So in place of return PendingIntent.getService(mActivity, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
use this piece of cake
return PendingIntent.getBroadcast(mActivity, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
and make sure you have declared your BroadcastReceiver in application manisfest file.Good luck!!!!

Beware: Geofences are indeed being removed when Location Provider Settings change or the device is restarted. Unfortunately the Android documentation doesn't mention this anywhere.
To counter this, you can register for a Boot-Completed Receiver and a Location Provider Changed Receiver:
<!-- Boot Completed Receiver -->
<receiver android:name="com.mydemoapp.geofencing.BootCompleteReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<!-- Location Service Provider Changed Receiver -->
<receiver android:name="com.mydemoapp.geofencing.LocationProviderChangedReceiver">
<intent-filter>
<action android:name="android.location.PROVIDERS_CHANGED" />
</intent-filter>
</receiver>
Inside these two BroadcastReceivers you can implement your logic of re-registering your previously deleted geofences.

In the Manifest you have registered the Service.
<service
android:name="com.example.zukami.apps.blynk.geofence.ReceiveTransitionsIntentService"
android:exported="true" >
</service>
But you have used broadcast receiver so can be an issue there. I am not sure about the broadcast receiver but with ReceiveTransitionIntent it does work as per the documentation.
However now i am stuck because when Location Service is Disabled or When Device is restarted i think Geofences are removed and I am not able to Add the Geofences back in Background.

Android Geofence only works with opened app

I'm doing a serious research on this topic for many days... I saw many topics here too...
But unfortunately I couldn't find a solution....
I'm writing an app that uses the new Google API for Geofence...
Well, I can handle "ins" and "outs" of a geofence, but only if my app is open! Even if I'm with wifi on, gps on, and 3G on, but the app, it does not trigger any event...Just if the app is open...

geofences.add(geofence);
try

mGeofenceRequester.addGeofences(geofences);
addCircleGeofence(raio);
}
catch (UnsupportedOperationException e)
{

Any help will be great!
Thanks!

I had the same exact problem. Here is what I answered over there: So after playing around with this a bit, it looks like the ReceiveTransitionsIntentService (as defined in the sample code) will stop getting the notifications when the app is not around. I think this is a big problem with the example code... Seems like that will trip folks like me up.
So I used a broadcast receiver instead, and so far it seems to be working from my tests.
Add this to the manifest:
<receiver android:name="com.aol.android.geofence.GeofenceReceiver"
android:exported="false">
<intent-filter >
<action android:name="com.aol.android.geofence.ACTION_RECEIVE_GEOFENCE"/>
</intent-filter>
</receiver>
Then in the GeofenceRequester class you need to change the createRequestPendingIntent method so that it goes to your BroadcastReceiver instead of the ReceiveTransitionsIntentService. MAKE SURE AND NOTE the change to .getBroadcast instead of getService. That got me hung up for a while.
private PendingIntent createRequestPendingIntent() {
// If the PendingIntent already exists
if (null != mGeofencePendingIntent) {
// Return the existing intent
return mGeofencePendingIntent;
// If no PendingIntent exists
} else {
// Create an Intent pointing to the IntentService
Intent intent = new Intent("com.aol.android.geofence.ACTION_RECEIVE_GEOFENCE");
//MAKE SURE YOU CHANGE THIS TO getBroadcast if you are coming from the sample code.
return PendingIntent.getBroadcast(
context,
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
}
Then I added the GeofenceReceiver class that looks something like this:
public class GeofenceReceiver extends BroadcastReceiver {
Context context;
Intent broadcastIntent = new Intent();
#Override
public void onReceive(Context context, Intent intent) {
this.context = context;
broadcastIntent.addCategory(GeofenceUtils.CATEGORY_LOCATION_SERVICES);
if (LocationClient.hasError(intent)) {
handleError(intent);
} else {
handleEnterExit(intent);
}
}
private void handleError(Intent intent){
// Get the error code
int errorCode = LocationClient.getErrorCode(intent);
// Get the error message
String errorMessage = LocationServiceErrorMessages.getErrorString(
context, errorCode);
// Log the error
Log.e(GeofenceUtils.APPTAG,
context.getString(R.string.geofence_transition_error_detail,
errorMessage));
// Set the action and error message for the broadcast intent
broadcastIntent
.setAction(GeofenceUtils.ACTION_GEOFENCE_ERROR)
.putExtra(GeofenceUtils.EXTRA_GEOFENCE_STATUS, errorMessage);
// Broadcast the error *locally* to other components in this app
LocalBroadcastManager.getInstance(context).sendBroadcast(
broadcastIntent);
}
private void handleEnterExit(Intent intent) {
// Get the type of transition (entry or exit)
int transition = LocationClient.getGeofenceTransition(intent);
// Test that a valid transition was reported
if ((transition == Geofence.GEOFENCE_TRANSITION_ENTER)
|| (transition == Geofence.GEOFENCE_TRANSITION_EXIT)) {
// Post a notification
List<Geofence> geofences = LocationClient
.getTriggeringGeofences(intent);
String[] geofenceIds = new String[geofences.size()];
String ids = TextUtils.join(GeofenceUtils.GEOFENCE_ID_DELIMITER,
geofenceIds);
String transitionType = GeofenceUtils
.getTransitionString(transition);
for (int index = 0; index < geofences.size(); index++) {
Geofence geofence = geofences.get(index);
...do something with the geofence entry or exit. I'm saving them to a local sqlite db
}
// Create an Intent to broadcast to the app
broadcastIntent
.setAction(GeofenceUtils.ACTION_GEOFENCE_TRANSITION)
.addCategory(GeofenceUtils.CATEGORY_LOCATION_SERVICES)
.putExtra(GeofenceUtils.EXTRA_GEOFENCE_ID, geofenceIds)
.putExtra(GeofenceUtils.EXTRA_GEOFENCE_TRANSITION_TYPE,
transitionType);
LocalBroadcastManager.getInstance(MyApplication.getContext())
.sendBroadcast(broadcastIntent);
// Log the transition type and a message
Log.d(GeofenceUtils.APPTAG, transitionType + ": " + ids);
Log.d(GeofenceUtils.APPTAG,
context.getString(R.string.geofence_transition_notification_text));
// In debug mode, log the result
Log.d(GeofenceUtils.APPTAG, "transition");
// An invalid transition was reported
} else {
// Always log as an error
Log.e(GeofenceUtils.APPTAG,
context.getString(R.string.geofence_transition_invalid_type,
transition));
}
}
/**

* detected. If the user clicks the notification, control goes to the main
* Activity.
*

*/
private void sendNotification(String transitionType, String locationName) {
// Create an explicit content Intent that starts the main Activity
Intent notificationIntent = new Intent(context, MainActivity.class);
// Construct a task stack
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
// Adds the main Activity to the task stack as the parent
stackBuilder.addParentStack(MainActivity.class);
// Push the content Intent onto the stack
stackBuilder.addNextIntent(notificationIntent);
// Get a PendingIntent containing the entire back stack
PendingIntent notificationPendingIntent = stackBuilder
.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
// Get a notification builder that's compatible with platform versions

// Set the notification contents

.setContentText(

// Get an instance of the Notification manager
NotificationManager mNotificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
// Issue the notification
mNotificationManager.notify(0, builder.build());
}
}
Hopefully that helps someone else.

I had a similar issue and after trying various ways I could finally fix the issue. Unfortunately, the android documentation fails to mention these issues.
The android geofences get removed every time you reboot your device or every time you toggle the location mode.
So Add a broadcast receiver to listen to device reboots and location mode changes, and add the geofences again in the receiver.
I have posted a detailed explanation here
