I have service with BroadcastReceiver.
Register actions:
BluetoothDevice.ACTION_ACL_CONNECTED
BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED
BluetoothDevice.ACTION_ACL_DISCONNECTED
After connect/disconnect with other device on the Galaxy S3 and Fly iq280 onReceived() was called, but on a Google Nexus 7 is not.
Maybe I do something wrong?
My code:
private void registerConnectionBroadcast() {
IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_ACL_CONNECTED);
IntentFilter filter2 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED);
IntentFilter filter3 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED);
IntentFilter filter4 = new IntentFilter(BluetoothAdapter.ACTION_STATE_CHANGED);
registerReceiver(mReceiver, filter1);
registerReceiver(mReceiver, filter2);
registerReceiver(mReceiver, filter3);
registerReceiver(mReceiver, filter4);
}
private BroadcastReceiver mReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
String deviceAddress = device != null ? device.getAddress() : "";
Log.d(TAG, deviceAddress);
if (!isConnected()) {
SettingsSupport.setDeviceAddress(deviceAddress, ReceiverService.this);
}
String action = intent.getAction();
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
Log.d("ConnectionBroadcastReceiver", "Device found");//Device found
}
else if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
Log.d("ConnectionBroadcastReceiver", "Device is now connected");//Device is now connected
}
else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
Log.d("ConnectionBroadcastReceiver", "Done searching");//Done searching
}
else if (BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED.equals(action)) {
Log.d("ConnectionBroadcastReceiver", "Device is about to disconnect");//Device is about to disconnect
}
else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) {
Log.d("ConnectionBroadcastReceiver", "Device has disconnected");//Device has disconnected
}
else if (BluetoothAdapter.ACTION_STATE_CHANGED.equals(action)) {
Log.d(TAG, "Bluetooth state is changed to " + state);
}
}
};
In my case it was called on Nexus 4 but wasn't on Samsung S3.
I don't think that it would make any difference, but you can try registering the receiver in the manifest xml.

I have been trying to implement a way that the application detects wake word like "Hey google" or "Jarvis". I did some research and found out porcupine helps towards solving the wake word problem but now the problem is I can't seem to trigger startRecognition() to listen again for the user input and then carry forward with it. I still tried to trigger startRecognition() but then it was asking me to do speechRecognizer.Destroy() which I tried doing with the porcupine onDestroy method but then it just stopped working. Sorry if I confused anyone, I will attach my code I will really appreciate everyone's help as I have been trying to solve this problem for a while now.
Another question is what does the following line of code do?
PendingIntent contentIntent = PendingIntent.getActivity(
this,

new Intent(this, MainActivity.class), // this line ?
0);
The code currently :(

Whenever i send message and tries to reload the activity to show the messages received or send i start activity again and have to make network request once again which i think will take much time when real user will use it. So, therefore i want to implement something else to make it instant messaging activity.
Any help would be appreciated Thanks in advance
Hei there,
I m trying to make an App with Android-Studio that can record sound using a Bluetooth-HS.
I know there are a lot of posts close to this, but i tried all the answers and it wont work for me.
My code gives me back a filled bytebuffer, however testing proves, its always the Phones Mic not the Headset-Mic.
If anyone could take a look at my code and point out why it wont use the BT-HS, that would be a huge help for me.

How to Create Geo fence(Creating and Monitoring Geo fences) on current latitude,longitude.
I am trying multiple example but not create.
Using this code:
public Geofence geofence(float radius, double latitude, double longitude) {
String id = UUID.randomUUID().toString();
return new Geofence.Builder()
.setRequestId(id)
.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER)
.setCircularRegion(latitude, longitude, radius)
.setExpirationDuration(Geofence.NEVER_EXPIRE)
.build();
}
There's this tutorial from Google, that's very easy to follow:
http://io2015codelabs.appspot.com/codelabs/geofences
There's also a course at Udacity that teaches location services, including geofences:
https://www.udacity.com/course/google-location-services-on-android--ud876-1
Add Google Play Services to Gradle File:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.google.android.gms:play-services:7.3.0'
}
Add to Manifest File:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
Add to Activity's XML Layout file:
<Button
android:id="#+id/add_geofences_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:onClick="addGeofencesButtonHandler"
android:text="Add GeoFences" />
Add to Activity's Java File:
public class MainActivity extends Activity
implements
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener,
ResultCallback<Status>{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAddGeofencesButton = (Button) findViewById(R.id.add_geofences_button);
// Empty list for storing geofences.
mGeofenceList = new ArrayList<Geofence>();
// Get the geofences used. Geofence data is hard coded in this sample.
populateGeofenceList();
// Kick off the request to build GoogleApiClient.
buildGoogleApiClient();
}

mGoogleApiClient = new GoogleApiClient.Builder(this)

entry.getValue().latitude,
entry.getValue().longitude,
Constants.GEOFENCE_RADIUS_IN_METERS
)
.setExpirationDuration(Constants.GEOFENCE_EXPIRATION_IN_MILLISECONDS)

} else {
// Get the status code for the error and log it using a user-friendly message.
String errorMessage = GeofenceErrorMessages.getErrorString(this,

Create a java file called Constans:
public class Constants {
public static final long GEOFENCE_EXPIRATION_IN_MILLISECONDS = 12 * 60 * 60 * 1000;
public static final float GEOFENCE_RADIUS_IN_METERS = 20;

// Googleplex.
LANDMARKS.put("Japantown", new LatLng(37.785281,-122.4296384));
// Test
LANDMARKS.put("SFO", new LatLng(37.621313,-122.378955));
}
}
Create a java file called GeofenceTransitionsIntentService:
public class GeofenceTransitionsIntentService extends IntentService {
protected static final String TAG = "GeofenceTransitionsIS";
public GeofenceTransitionsIntentService() {
super(TAG); // use TAG to name the IntentService worker thread
}
#Override
protected void onHandleIntent(Intent intent) {
GeofencingEvent event = GeofencingEvent.fromIntent(intent);
if (event.hasError()) {
Log.e(TAG, "GeofencingEvent Error: " + event.getErrorCode());
return;
}
}
String description = getGeofenceTransitionDetails(event);
sendNotification(description);
}
private static String getGeofenceTransitionDetails(GeofencingEvent event) {
String transitionString =
GeofenceStatusCodes.getStatusCodeString(event.getGeofenceTransition());
List triggeringIDs = new ArrayList();
for (Geofence geofence : event.getTriggeringGeofences()) {
triggeringIDs.add(geofence.getRequestId());
}
return String.format("%s: %s", transitionString, TextUtils.join(", ", triggeringIDs));
}
private void sendNotification(String notificationDetails) {
// Create an explicit content Intent that starts MainActivity.
Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
// Get a PendingIntent containing the entire back stack.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class).addNextIntent(notificationIntent);
PendingIntent notificationPendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
// Get a notification builder that's compatible with platform versions >= 4
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
// Define the notification settings.
builder.setColor(Color.RED)
.setContentTitle(notificationDetails)
.setContentText("Click notification to return to App")
.setContentIntent(notificationPendingIntent)
.setAutoCancel(true);
// Fire and notify the built Notification.
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
