Android GCM Registration Id

Android GCM Registration Id - android

I want to use GCM. I tried with following in the client side:

}
}
It's showing no error. GCMRegistrar.getRegistrationId(this) is always returning " "(empty string). So, It always tries to register and I never got registerId.
Anything to be done?
Also, While implementing the server side code, Do I need to send this register Id and save all the id's in a database and send them?

Android Broadcast Receiver in Service

I'm trying to make service that will do something each time phone call is ended. My problem is that service doesn't receive any broadcasts.
I've implemented it like that:
package com.kubasienki.spedycja;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.IBinder;
import android.util.Log;
/**
* Created by kuba on 11/4/2015.
*/
public class FirstService extends Service {
private static String TAG = "kurwa";
final BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(action.equals("android.provider.Telephony.CALL_STATE_IDLE")){
Log.v("kurwa", "skonczono");
}
else if(action.equals(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED)){
Log.v("kurwa", "???");
}
else {
Log.v("kurwa", "??!!!?");
}
}
};
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
Log.d(TAG, "FirstService started");
IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.TelephonyManager.CALL_STATE_IDLE");
filter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
registerReceiver(receiver, filter);
//this.stopSelf();
}
#Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
Log.d(TAG, "FirstService destroyed");
}
}
Manifest:
<?xml version="1.0" encoding="utf-8"?>

And starting service :
startService(new Intent(this, FirstService.class));

Android wear module listener service not receiving data from mobile module

I am developing a sample watch face wherein a user would be able to select some color configuration on mobile app triggering changes on wear app watch face.
Here is what I have in mobile app to send configuration:
package com.quicklyjava.templatewatchface;

import com.google.android.gms.wearable.PutDataRequest;
import com.google.android.gms.wearable.Wearable;
/**

public class WearConnection {
private final GoogleApiClient mGoogleApiClient;
private String TAG = "wear.bridge";
public WearConnection(Context context) {
mGoogleApiClient = new GoogleApiClient.Builder(context)
.addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
#Override
public void onConnected(Bundle connectionHint) {
Log.d(TAG, "onConnected: " + connectionHint);
}
#Override
public void onConnectionSuspended(int cause) {
Log.d(TAG, "onConnectionSuspended: " + cause);
}
})
.addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {
#Override
public void onConnectionFailed(ConnectionResult result) {
Log.d(TAG, "onConnectionFailed: " + result);
}
})
.addApi(Wearable.API)
.build();
}
public void connect(){
mGoogleApiClient.connect();
}
public void disconnect() {
mGoogleApiClient.disconnect();
}
public void sendColor(String path, int color) {
PutDataMapRequest dataMap = PutDataMapRequest.create(path);
dataMap.getDataMap().putInt("value", color);
PutDataRequest request = dataMap.asPutDataRequest();
PendingResult<DataApi.DataItemResult> pendingResult = Wearable.DataApi.putDataItem(mGoogleApiClient, request);
pendingResult.setResultCallback(new ResultCallback<DataApi.DataItemResult>() {
#Override
public void onResult(DataApi.DataItemResult dataItemResult) {
Log.d("wear", "sent: " + dataItemResult);
}
});
}
}
Here is the manifest for mobile:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Here is the listener service I implemented in wear:
package com.quicklyjava.templatewatchface;
import android.content.Intent;
import android.content.SharedPreferences;
import android.net.Uri;
import android.preference.PreferenceManager;
import android.util.Log;

import com.google.android.gms.wearable.Wearable;
import com.google.android.gms.wearable.WearableListenerService;
import java.util.List;
import java.util.concurrent.TimeUnit;
/**

*/
public class TemplateWatchConfigListenerService extends WearableListenerService {
private static final String TAG = "DataLayerSample";
private SharedPreferences preferences;
// keys for the data map
private String KEY_DOT_COLOR="com.quicklyjava.backgroundcolor";
GoogleApiClient mGoogleApiClient;
#Override
public void onCreate() {
super.onCreate();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.build();
mGoogleApiClient.connect();
preferences = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
}
#Override
public void onDataChanged(DataEventBuffer dataEvents) {
LOGD(TAG, "onDataChanged: " + dataEvents);
final List<DataEvent> events = FreezableUtils.freezeIterable(dataEvents);
dataEvents.close();
if(!mGoogleApiClient.isConnected()) {
ConnectionResult connectionResult = mGoogleApiClient.blockingConnect(30, TimeUnit.SECONDS);
if (!connectionResult.isSuccess()) {
Log.e(TAG, "WatchFaceConfigListenerService failed to connect to GoogleApiClient.");
return;
}
}
// Loop through the events and send a message back to the node that created the data item.
for (DataEvent event : events) {
Uri uri = event.getDataItem().getUri();
String path = uri.getPath();
DataMapItem item = DataMapItem.fromDataItem(event.getDataItem());
switch (path) {
case "/backgroundColor":
putIntPreference(KEY_DOT_COLOR, item.getDataMap().getInt("value"));
break;
default:
Log.e("TempWatchList","Default");
}
getBaseContext().sendBroadcast(new Intent("com.quicklyjava.action.config_changed"));
}
}
#Override
public void onPeerConnected(Node peer) {
LOGD(TAG, "onPeerConnected: " + peer);
}
#Override
public void onPeerDisconnected(Node peer) {
LOGD(TAG, "onPeerDisconnected: " + peer);
}
public static void LOGD(final String tag, String message) {
if (Log.isLoggable(tag, Log.DEBUG)) {
Log.d(tag, message);
}
}
private void putIntPreference(String key, int value) {
preferences
.edit()
.putInt(key, value)
.apply();
}
}
Finally here is the wear manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.quicklyjava.templatewatchface" >
<uses-sdk android:minSdkVersion="21"
android:targetSdkVersion="21" />

<!-- Required to act as a custom watch face. -->
<uses-permission android:name="com.google.android.permission.PROVIDE_BACKGROUND" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<service
android:name=".TemplateWatchService"
android:label="#string/template_name"
android:permission="android.permission.BIND_WALLPAPER" >
<meta-data
android:name="android.service.wallpaper"
android:resource="#xml/watch_face" />
<meta-data

<meta-data
android:name="com.google.android.wearable.watchface.preview_circular"

<intent-filter>
<action android:name="android.service.wallpaper.WallpaperService" />
<category android:name="com.google.android.wearable.watchface.category.WATCH_FACE" />
</intent-filter>
</service>
<service android:name=".TemplateWatchConfigListenerService" >
<intent-filter>
<action android:name="com.google.android.gms.wearable.BIND_LISTENER" />
</intent-filter>
</service>
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>
The onDataChanged method is not getting triggered when the sendColor method in mobile app is called. Is there anything I am missing?

add a key-value in the data item map
map.put("system", System.currentmillions())
and send again

yeah, you are missing some important meta-data tags
In wear manifest, add these tag to the WatchFaceService's service tag:
<meta-data <!-- Companion config -->
android:name="com.google.android.wearable.watchface.companionConfigurationAction"
android:value="com.example.package.CONFIG_FACE" />
<meta-data <!-- wear config -->
android:name="com.google.android.wearable.watchface.wearableConfigurationAction"
android:value="com.example.package.CONFIG_FACE" />
And in your Companion manifest , just add only these lines to the CompanionConfigActivity's activity tag :
<intent-filter>
<action android:name="com.example.package.CONFIG_FACE" />
<category android:name="com.google.android.wearable.watchface.category.COMPANION_CONFIGURATION" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
The code :
com.example.package.CONFIG_FACE
must be same in both the manifests.

I can not find answer for this problem.
I am building some Android application based on sms services and
I found callback very difficult.
I want/need to call my primary application class MainActivity from inside function onReceive (class SMSReceiver).
Toast works perfectly but any attempt to call public void OnSmsReceived() (class MainActivity) is unsuccessful.
// Main class
public class MainActivity extends Activity {
public void OnSmsReceived() {
System.out.println(TAG + ": OnSmsReceived " + "OK ");
}
/* more not important at this moment code bellow */
}
// Brodcast class
public class SMSReceiver extends BroadcastReceiver {
private static final String TAG = "SMSReceiver";
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "SMS received.", Toast.LENGTH_LONG).show();
System.out.println(TAG + ": " + "onReceive");
//How to call MainActivity form here?
}
}

Ok, I finaly made that working:
This is really working code
Thank you for intent ...

use context in the onReceive Method and call context.startActivity(context , yourActivity.class);

you can't use context.startActivity(context , MainActivity.class);
but you can choose below method to resolve this issue:
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
context.startActivity(intent, bundle)

I experimented lots of approaches.
I did not say but it is for targetSdkVersion="8"
and some of those functions you gave me did not work on this old system
I could not find working way with use of context and intent. This always caused crash.
I found way with static fields and function in MainActivity,even that works and print something, it crushed after that....
After all this works for me very well.
Of course it is draft but this allow to work with main class.

I think i m committing a mistake in my menifest file. please have a look on this. thanks.

First, unlike other broad casted intents, for Intent.ACTION_SCREEN_OFF and Intent.ACTION_SCREEN_ON you CANNOT declare them in your Android Manifest! so You need to make a service which will keep on running like this
public static class UpdateService extends Service {
#Override
public void onCreate() {
super.onCreate();
// register receiver that handles screen on and screen off logic
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new Receiver();
registerReceiver(mReceiver, filter);
}
#Override
public void onStart(Intent intent, int startId) {
boolean screenOn = intent.getBooleanExtra("screen_state", false);
if (!screenOn) {
// your code
} else {
// your code
}
}
}
and your receiver can be something
public class Receiver extends BroadcastReceiver {
private boolean screenOff;
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
screenOff = true;
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
screenOff = false;
}
Intent i = new Intent(context, UpdateService.class);
i.putExtra("screen_state", screenOff);
context.startService(i);
}
}

Here is my complete code. Hope this helps. I was basically making a look screen app. This will disable your default lock screen. and on power button press it will start a service and runs to look for power button press event.
