I am trying to build an app where the strength of the nearest beacon is detected (by the signal strength) and the corresponding API must be called (with the beacon ID as a parameter). The app asks for location the first time and runs very well (detects the nearest beacon). But after I close the app and reopen it, the beacon ID will be empty always (string2 variable is being set with beacon ID). Why is it running the first time and not subsequent times?
Whenever I clear the data of the app, the app asks for location and runs fine. I have coded the entire segment again three times and yet I encounter the same problem.
I have tried to trace the flow through log statements. I observed that onBeaconServiceConnect() method isn't executing the second time (unless the app's data is cleared).
AsyncTask:
public class Navigate extends AsyncTask<String, String, String> {

while (!bid.equals(strings[1])) {
try {
imageURL=callAPI("bid1","bid3");
Log.e("BeaconID", bid); //The default value of bid will be printed and not the beacon ID.

I want my app track with beacon all the time
it seem work fine been a while when it start tracking
after that, didRangeBeaconsInRegion() has an empty beacons collection
Here my code

} catch (RemoteException e) { }
}
}

}
}
}
EDIT: It happen like this both foreground and background. But If I kill my app and open it again, I can finds beacon but just a moment too.
EDIT2: isAfterEndTime is return false while it cannot finds any beacons. But the didExitRegion is triggered swap with didEnterRegion and it finds zero beacons
PS. I want to track with only one beacon at a time
PS.2 Sorry for my bad English. I'm not sure, are you get what I want to ask clearly or not?
A few things to check:
Make sure this code is not being triggered. I cannot see the definition of the method, but if it returns true, it will cause ranging to stop:
if(isAfterEndTime()) {
stopBeaconRanging();
}
Add a debug line in the didExitRegion to make sure it is not being called. (Since it also stops ranging.) As an aside, I don't think you need code that does this -- there is no efficiency cost to just continuing ranging if you aren't detecting beacons anyway.
Make sure this line of code is only executed once, as the RegionBootstrap is not designed to be created repeatedly:
regionBootstrap = new RegionBootstrap(this, new Region("ranged region", null, null, null));
Rather than repeatedly making a new RegionBootstrap object, just create one once at the beginning of your program. If you then want to change the monitored regions, you can do so with beaconManager.stopMonitoringBeaconsInRegion(region1); and beaconManager.startMonitoringBeaconsInRegion(region2);
I need to range beacons on the background using Altbeacons library(work properly on foreground mode)
On my android monitor the log never shows the message for the didRangeBeaconsInRegion method.
On the didEnterRegion, the messages are displayed correctly.
I tried the code below but no success, can any one guide me how to do it?

It looks like the code simply needs to call:
beaconManager.setRangeNotifier(this);
I'm trying to get the bootstrap to gather id2 and id3 from iBeacons and start an activity with them. The problem is that the application wouldn't start from the intent and I keep seeing D/BeaconService﹕ Calling ranging callback D/Callback﹕ attempting callback via intent: ComponentInfo{com.rp_ds.chequeplease/org.altbeacon.beacon.BeaconIntentProcessor}
Below is my code:

I do get a didEnterRegion call but there wasn't a didRangeBeaconsInRegion call. The beacons are also recognized.
D/BeaconParser﹕ This is a recognized beacon advertisement -- 0215 seen
D/BeaconIntentProcessor﹕ got an intent to process
D/RangingData﹕ parsing RangingData
D/RangingData﹕ parsing RangingData
D/BeaconIntentProcessor﹕ got ranging data
D/BeaconIntentProcessor﹕ but ranging notifier is null, so we're dropping it.
The range notifier needs to be set like this:
#Override
public void didEnterRegion(Region arg0) {
Log.d(TAG, "Got a didEnterRegion call");
try {
beaconManager.startRangingBeaconsInRegion(arg0);
beaconManager.setRangeNotifier(this);
} catch (RemoteException e) {
e.printStackTrace();
}
}
Make sure the containing class implements the RangeNotifier interface.
I am trying to see beacons with the estimote sdk in android but with no luck!I can see all the estimote beacons but with all other beacons is not working (fobo beacons etc.) I am using the uuid for the fobo beacons inside the Region constructor and i can see in the logcat that the bluetooth can see the devices but estimode sdk is not collecting it as a beacon!Any ideas why this is happening? I m posting the code below:
private static final String FOBO_PROXIMITY_UUID = "00158800-587d-2206-d52b-fb6d6e2f0001";
private static final Region FOBOBEACONS = new Region("rid", FOBO_PROXIMITY_UUID , null, null);
public void BeaconManager(){
beaconManager = new com.estimote.sdk.BeaconManager(this);
beaconManager.setBackgroundScanPeriod(5000, 30000);
beaconManager.setForegroundScanPeriod(7000, 5000);
beaconManager.setRangingListener(new com.estimote.sdk.BeaconManager.RangingListener() {
#Override
public void onBeaconsDiscovered(final Region arg0, final List<Beacon> arg1) {
// TODO Auto-generated method stub
runOnUiThread(new Runnable() {
#Override

// Note that beacons reported here are already sorted by estimated
// distance between device and beacon.
int test=0;
if(arg1.size()<=0){
Toast.makeText(MainActivity.this, "No beacon found",
Toast.LENGTH_SHORT).show();
}else{
for (int i = 0; i < arg1.size(); i++) {
String beac=arg1.get(i).getProximityUUID();
Toast.makeText(MainActivity.this, "I found a beacon with UUID; "+beac,
Toast.LENGTH_SHORT).show();
}
}
// adapter.replaceWith(beacons);
}
});
}
});
connectToService();
}
private void connectToService() {
beaconManager.connect(new com.estimote.sdk.BeaconManager.ServiceReadyCallback() {
#Override
public void onServiceReady() {
try {
com.estimote.sdk.utils.L.enableDebugLogging(true);
beaconManager.startRanging(FOBOBEACONS);
} catch (RemoteException e) {
Toast.makeText(MainActivity.this, "Cannot start ranging, something terrible happened",
Toast.LENGTH_LONG).show();
}
}
});
}
This is Wojtek Borowicz, I'm a community evangelist at Estimote. Actually, Estimote SDK does not support Beacons from other vendors - that's why you cannot detect them.
Cheers.
Maybe check this link.. not tried it yet myself but plan to at some point.
https://github.com/AlvinBert
An Android source code of iBeacon SDK. without any limit on Android.
It can detect all iBeacons.
I am having difficulty figuring out how to resolve this issue, I am not sure if I am not setting up threads correctly or if it is even possible to resolve things properly.
This is an Android app that reads certain strings out as TTS (using the native Android TTS) at certain timings. During this TTS reading, the user should be able to barge-in with instructions such as "Stop" or "Pause." This recognition is done by using the iSpeech API.
Our current solution is to have the TTS running as a Thread that will output the proper strings. Once the user presses a button to begin the voice recognition (using an Intent), the app does voice recognition and handles it perfectly, but then TTS never again outputs anything. Logcat shows the following error:
11-28 02:18:57.072: W/TextToSpeech(16383): speak failed: not bound to TTS engine
I have thought about making the voice recognition a thread of its own that pauses the TTS, but the problem would then be that the timer controlling the TTS would become unsynced with what it should be.
Any advice or help would be appreciated.
Relevant code regarding the thread and the intent are below:
Thread

super.onCreate(savedInstanceState);
//Prevent device from sleeping mid build.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

mPlayer = MediaPlayer.create(BuildOrderActivity.this, R.raw.bing);
params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");
tts = new TextToSpeech(BuildOrderActivity.this, new TextToSpeech.OnInitListener() {
#SuppressWarnings("deprecation")
public void onInit(int status) {
if(status != TextToSpeech.ERROR)
{
tts.setLanguage(Locale.US);
tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {
public void onUtteranceCompleted(String utteranceId) {
mPlayer.start();
}
});
}
}
