this is my Broadcast_Receiver
public class Broadcast_Receiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context, Notification_Intent_Service.class));
}
}
and this is my IntentService
public class Notification_Intent_Service extends IntentService {
public Notification_Intent_Service() {
super("GcmIntentService");
}
#Override
protected void onHandleIntent(Intent intent) {
Log.d("s","w");
}
}
at the end my manifest
<receiver
android:name=".Service.Broadcast_Receiver"
android:label="#string/app_name"
android:enabled="true" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:name=".Service.Notification_Intent_Service" />
i install the application and its didnt show any message tell me that's it run
did its want to start it from Activity ? if i must start it from Activity how can i make it auto start at any time without start it from Activity

I found really interesting option in Lenovo K5
When this option is active, my background services doesn't activated after restart of the device. I searched everywhere in the web, and I set some tweaks in the manifest, but nothing helps.
I notice that in some apps, that option is not activated, like Facebook or Viber. So when they can made it, I'm sure that it have some workaround of the problem.
Thanks in advance.

I tried to register the broadcast receiver in the manifest but the onReceive method isn't invoked. What am I doing wrong?
manifest.xml
<receiver

android:exported="true"
android:enabled="true">
<intent-filter>
<action android:name="zzz.yyy.xxx.ui.storyboard.discussion.GROUPCHAT" />

</receiver>
Sending broadcast as below:
Intent intent = new Intent("zzz.yyy.xxx.ui.storyboard.discussion.GROUPCHAT");
intent.putExtra(BundleKeys.notification_post_id_forum,postId);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
Receiving broadcast in Fragment class as below:
#Override
public void onPause() {
clearUnreadCount();
LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(messageRefresher);
super.onPause();
}
public class MessageCountReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
String noti_post_id = intent.getStringExtra(BundleKeys.notification_post_id_forum);
int tempCount=PreferencesIMDStar.getIntValue(getActivity(),noti_post_id);
tempCount++;
PreferencesIMDStar.setIntValue(getActivity(),noti_post_id,tempCount);
if (getActivity() != null && noti_post_id.equalsIgnoreCase(post_id)) {
discussionPresenter.fetchCommentReply(post_id, true);
}
}
}
I have tried this
Trying to start a service on boot on Android
Also I have checked with http://blog.vogella.com/2011/12/11/automatically-starting-services-in-android-after-booting/
yet my app wont restart on Phone startup. Here's the code.
AndroidManifest.xml
<service android:name=".MyService">
</service>
<receiver android:name=".Autostart"
android:enabled="true"
android:exported="false">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
MyService
public class MyService extends Service implements LocationListener {
#Override
public IBinder onBind(Intent intent) {
return mBinder;
}
private final IBinder mBinder = new LocalBinder();
public class LocalBinder extends Binder {
MyService getService() {
return MyService.this;
}
}
#Override
public void onCreate() {
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i("LocalService", "Received start id " + startId + ": " + intent);
// We want this service to continue running until it is explicitly
// stopped, so return sticky.
return START_STICKY;
}
#Override
public void onDestroy() {
// Cancel the persistent notification.
this.stopSelf();
// Tell the user we stopped.
}
MainActivity
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
startService(new Intent(getBaseContext(), MyService.class));
Am I going wrong anywhere?
Edit:
public void onReceive(Context arg0, Intent arg1)
{
Intent intent = new Intent(arg0,MyService.class);
arg0.startService(intent);
Log.i("Autostart", "started");
}
This is my BroadcastReceiver.
Yet no results.
try register BroadcastReceiver for ACTION_BOOT_COMPLETED. The you can recieve startup broadcast.
public class BootBroadCast extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
Intent service=new Intent(context, MyService.class);
context.startService(service);
}
}
second you need add this in AndroidManifest.xml
<receiver android:name=".BootBroadCast" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" >
</action>
</intent-filter>
</receiver>
I have followed the article at vogella and was able to get my service started at Boot.
First of all, you should have a BroadcastReceiver for the event android.intent.action.BOOT_COMPLETED. Just follow the steps from the blog. It seems you have started the service on your app's 'onCreate'. This will get invoked only if the user starts your app.
When the system boots up, your receiver class's onReceive() method will be invoked. Here is where you should start your activity as below.
public class BootReceiever extebds BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, YourService.class);
context.startService(service);
}
}
From the research that I have done, it is better to start your service after a short delay as many applications / services may start at boot, so chances of low memory are more. I started my service after a small delay.
I'm trying to learn to use Android BroadcasReceiver.
I wrote this code but It doesn't work... I tryed for example to change the Time etc...
What is it wrong?
I added in the Manifest:
<receiver android:name="com.example.broadcastreceiverspike.Broadcast" >
<intent-filter android:priority="100">
<action android:name="android.intent.action.ACTION_SCREEN_ON" />
<action android:name="android.intent.action.ACTION_SCREEN_OFF" />
<action android:name="android.intent.action.TIME_SET" />
</intent-filter>
</receiver>
My simple BroadcasReceiver:
public class Broadcast extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("BROADCAST", "It worked");
Toast.makeText(context, "BROADCAST", Toast.LENGTH_LONG).show();
}
}
My Main Activity (default main Activity)
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
I solved!
"unlike other broad casted intents, for Intent.ACTION_SCREEN_OFF and Intent.ACTION_SCREEN_ON you CANNOT declare them in your Android Manifest! I’m not sure exactly why, but they must be registered in an IntentFilter in your JAVA code"
http://thinkandroid.wordpress.com/2010/01/24/handling-screen-off-and-screen-on-intents/
Manifest
<receiver android:name=".Broadcast" >
<intent-filter>
<action android:name="android.intent.action.TIME_SET" />
</intent-filter>
</receiver>
Main Activity Class
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// INITIALIZE RECEIVER
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new Broadcast();
registerReceiver(mReceiver, filter);
}
}
My broadcast receiver
public class Broadcast extends BroadcastReceiver {
public static String TAG = "BROADCAST";
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_TIME_CHANGED))
{
Log.d(TAG, "BROADCAST Cambio di orario");
Toast.makeText(context, "BROADCAST Cambio di orario", Toast.LENGTH_LONG).show();
}
else if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
// DO WHATEVER YOU NEED TO DO HERE
Log.d(TAG, "BROADCAST Screen OFF");
Toast.makeText(context, "Screen OFF", Toast.LENGTH_LONG).show();
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
// AND DO WHATEVER YOU NEED TO DO HERE
Log.d(TAG, "BROADCAST Screen ON");
Toast.makeText(context, "BROADCAST Screen ON", Toast.LENGTH_LONG).show();
}
}
}
Did you add the needed premissions?
uses-permission android:name="android.permission.READ_PHONE_STATE"
This is a receiver to handle when screen is off or on or locked:
public class ScreenReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF))
{
}
else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON))
{
}
else if(intent.getAction().equals(Intent.ACTION_USER_PRESENT))
{
}
}
}
this is the manifest:
<receiver android:name=".ScreenReceiver">
<intent-filter>
<action android:name="android.intent.action.USER_PRESENT" />
<action android:name="android.intent.action.SCREEN_OFF" />
<action android:name="android.intent.action.SCREEN_ON" />
</intent-filter>
</receiver>
Check out this tutorial about broadcast receivers.
Update:
I'm not sure you're using this tutorial, because there are lots of useful stuff in this tutorial, like this:
#Override
public void onResume() {
super.onResume();
// Register mMessageReceiver to receive messages.
LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
new IntentFilter("my-event"));
}
// handler for received Intents for the "my-event" event
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// Extract data included in the Intent
String message = intent.getStringExtra("message");
Log.d("receiver", "Got message: " + message);
}
};
#Override
protected void onPause() {
// Unregister since the activity is not visible
LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
super.onPause();
}
In other words, you've created a custom broadcast receiver class, but you haven't used it.
And also please check this.
I had the same problem and I fixed it (tested on 4.3 and 5.1). I WAS able to declare "android.intent.action.USER_PRESENT" inside the manifest, as long as you have the READ_PHONE_STATE permission, it is OK!! My mini app consists of a Broadcast receiver that reacts to the screen ON/OFF state, and runs a background service that does continuous voice recognition. If the screen is off, the recognition is turned off. Here is the code, enjoy: MANIFEST:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/> <receiver android:name="classes.VoiceLaunchReceiver" >
<intent-filter>
<action android:name="android.intent.action.USER_PRESENT" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
BROADCAST RECEIVER:
public class VoiceLaunchReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context ctx, Intent intent) {
Intent service = new Intent(ctx, VoiceLaunchService.class);
// service.putExtra(action, true);
Log.i("joscsr","Incoming Voice Launch Broadcast...");
if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {
Log.i("joshcsr", "************\nCSR Resumed (BC)\n************");
ctx.startService(service);
}
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
Log.i("joshcsr", "************\nCSR STOPPED by SCREEN (BC)\n************");
ctx.stopService(service);
}
}
}
As you can imagine, my USER_PRESENT broadcast receiver is not registered anywhere else. I do register ACTION_SCREEN_OFF and ON in the onCreate method of my service, who was triggered by my receiver.
#Override
public void onCreate() {
super.onCreate();
//Register screen ON/OFF BroadCast
launcher=new VoiceLaunchReceiver();
IntentFilter i=new IntentFilter(Intent.ACTION_SCREEN_OFF);
i.addAction(Intent.ACTION_SCREEN_ON);
registerReceiver(launcher,i);
Log.d("joshcsr","VoiceLaunch Service CREATED");
}
Finally I unregister the screen on/off in the onDestroy() of my service:
#Override
public void onDestroy() {
super.onDestroy();
unregisterReceiver(launcher);}
I wan't to start service at boot on android 4.0.3 but when i boot my device it not happen in my device and service not start.Help me please thank you
here is my manifest
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="com.android.testsharedpreference.MyService"></service>
<receiver android:name="com.android.testsharedpreference.BootReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" >
</action>
</intent-filter>
</receiver>
</application>
my boardcast receiver
public class BootReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED))
{
context.startService(new Intent(context,MyService.class));
}
}
}
and my service
public class MyService extends Service
{
#Override
public IBinder onBind(Intent intent)
{
return null;
}
#Override
public void onCreate()
{
super.onCreate();
Toast.makeText(MyService.this, "onCreate Service ", Toast.LENGTH_LONG).show();
}
#Override
public void onDestroy()
{
super.onDestroy();
Toast.makeText(MyService.this, "onDestroy Service ", Toast.LENGTH_LONG).show();
}
}
you should add add android.permission.RECEIVE_BOOT_COMPLETED as it was not required before ICS so the app was working fine but starting from ICS is you don't have this permission your app wont receive the boot completed intent
Don't forget to override the method "onStartCommand" in your MyService:
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
String action = intent == null ? null : intent.getAction();
Log.d("onStartCommand", "action = " + action);
/* ... */
return START_NOT_STICKY; // for example ...
}
