Autostart (BOOT_COMPLETED) does not work on the Nomi tablet

My broadcast receiver triggered by event BOOT_COMPLETED and works fine on many devices except Nomi C10103.
The message appears in the log on the device:
D/ActivityManager: send broadcast: android.intent.action.BOOT_COMPLETED, skip package: com.example.myPackageName
Sending message am broadcast -a android.intent.action.BOOT_COMPLETED com.example.myPackageName from adb shell also does not run the application.
Manifest code:
<receiver
android:name=".AutoRunReceiver">
<intent-filter android:priority="1000">
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<intent-filter android:priority="1000">
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
AutorunReceiver.java:
public class AutoRunReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
//приёмник автозагрузки
if (intent != null && intent.getAction() != null) {
final String msg="intent:"+intent+" action:"+intent.getAction();
Log.d("myLogs",msg);
Toast.makeText(context,msg,Toast.LENGTH_LONG).show();
}
}
}

I realized that the problem is not in the code, but the device itself. Autoplay not working on my tablet for any application. As a workaround I have used the event "android.intent.action.USER_PRESENT", which is triggered after the device loading and screen unlocking.

<action android:name="android.intent.action.QUICKBOOT_POWERON" />
its working fine for me.if its lenovo mobile you should wait at least 2 minutes then it will open automatically.

Start a service when phone reboot completed

I want to Start a service when phone reboot completed. I will install my app but will not launch it.
I have proceed with the following ways using Broadcast Receiver listening to BOOT_COMPLETED intent.
My Receiver is as follows...
public class MyReceiver extends BroadcastReceiver {
static final String TAG = "MyReceiver";
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Log.d(TAG, "******* OnReceive");
Log.d(TAG, "Boot Completed Caught");
context.startService(new Intent(context, MyService.class));
}
}
In Manifest I have added the following lines of code:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<service android:name="MyService"
android:enabled="true" >
<intent-filter>
<action android:name="com.example.logic.MyService" />
</intent-filter>
</service>
<receiver android:name="MyReceiver" android:enabled="true" android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
But receiver is not listening once boot is completed. Remember I have only installed my app but never launch it.But my requirement is such that I should not launch my app after installing it in my device. Anybody can help me on this.
I googled it and found that as I have not launched my app it is in stopped state and boot completed intent is ignoring my receiver. The below links that might help you in understanding my issue:

the service and MyReceiver must be full packagename,
like this

Is service is started automatically

I am new to android .Is service in android is started automatically when the mobile is switch on??if yes that's great.if no can any one explain how can i start the particular service ??

No, service is not started automatically after device boot. but you can register an android.intent.action.BOOT_COMPLETED for Starting Service when Device boot complete as:
AndroidManifest.xml :
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED">
</uses-permission>
<receiver android:name=".BootReceiver" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>
BootReceiver.java :
public class BootReceiver extends IntentReceiver
{
static final String ACTION = "android.intent.action.BOOT_COMPLETED";
public void onReceiveIntent(Context context, Intent intent)
{
if (intent.getAction().equals(ACTION))
{
context.startService(new Intent(context,YourService.class));
}
}
}

In user based application service does not start automatically
you need to add below code
<receiver android:name="com.wallpaper.StartReceiver" xmlns:android="#unknown">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>

you better read something on Broadcast receiver from here
http://www.vogella.com/articles/AndroidBroadcastReceiver/article.html
A broadcast receiver is an Android component which allows to register for system or application events(in your case the ACTION_BOOT_COMPLETED)
As soon as the Android loads up it broadcast a message that the boot is completed and all the applications that are registered to receivce that event will receive it and you can do your stuff...
It can be done using this code below by adding it to the manifest file
<receiver android:name="some_pagacakge_name" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
here are some links for it
http://www.grokkingandroid.com/android-tutorial-broadcastreceiver/

you can start your service startService(intent)
To run it on Phone restart
add following permission in manifest file
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
and declared a Broadcast Receiver like
<receiver android:name=".BootReceiver"
android:label="BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
</intent-filter>
</receiver>
and then
public class BootReceiver extends BroadcastReceiver {
private static final String TAG="BootReceiver";
#Override public void onReceive(Context context,Intent intent){
try{
context.startService(new Intent(context,yourServiceName.class));
Log.i(TAG,"Starting Service yourServiceName");
}catch(Exception e){
Log.e(TAG,e.toString());
}
}
}

Its depends on your requirement what kind of service you want to start and when you want to start that service. if you want to start particular service on startup then you have to register the reciever as Devangi Desai has mentioned and then you need to issue the startService() method.
public class Receiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String intentAction = intent.getAction();
if (intentAction.equals(Intent.ACTION_BOOT_COMPLETED))
context.startService(new Intent(context,
ConnectionService.class));
}
}
Here ConnectionService.class is class which extends a service and has the implementation of service.

They are not started automatically unless you explicitly define in the manifest that they should be started at boot time. To do this, you need to add the action
<action android:name="android.intent.action.BOOT_COMPLETED" />
in your manifest file for your service.
example:
<receiver android:name="MyStartupIntentReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
</receiver>
Please read this official guide for more detailed information about services:

android package restarted broadcast not working

I am developing an app which needs a broadcast when app opens every time. I had registered the receiver in manifest like this.
<receiver android:name="package.broadcast.example" >
<intent-filter>
<action android:name="android.intent.action.PACKAGE_RESTARTED" />
<data android:scheme="package"/>
</intent-filter>
</receiver>
But i cant able to receive the broadcast. I spent 3 hours on this still i cant find wats the mistake. Can anyone refer me the working example of this broadcast. Thanks.

Restarted Application/Package does not receive broadcast...
check the following link for details
you can check this link
http://developer.android.com/reference/android/content/Intent.html#ACTION_PACKAGE_RESTARTED

do u have the following code which extends BroadcastReceiver, if not than try the following code:
public class AutoConnection extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if ((intent.getAction() != null)
&& (intent.getAction()
.equals("android.intent.action.PACKAGE_RESTARTED"))) {
Toast.makeText(context, "Pacakge Restarted",
Toast.LENGTH_LONG).show();
}
}
}
and in android manifest file add the following code:
<receiver android:name=".AutoConnection" >
<intent-filter>
<action android:name="android.intent.action.PACKAGE_RESTARTED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>

Application calling with screen lock

I want to launch an application immediately after the screen gets unlocked and at the time of booting. How is it possible? What changes do I need to make?

To launch your application when the screen locks, you need to register a BroadcastReceiver for the Intent.ACTION_SCREEN_OFF Intent for more information check the example http://thinkandroid.wordpress.com/2010/01/24/handling-screen-off-and-screen-on-intents/
To launch your application at the time of boot you need a broadcast receiver that listens for the BOOT_COMPLETED action, please refer How to start an Application on startup?
First, you need the permission in your manifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Also, in your manifest, define your service and listen for the boot-completed action:
<service android:name=".MyService" android:label="My Service">
<intent-filter>
<action android:name="com.myapp.MyService" />
</intent-filter>
</service>
<receiver
android:name=".receiver.StartMyServiceAtBootReceiver"
android:enabled="true"
android:exported="true"
android:label="StartMyServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Then you need to define the receiver that will get the BOOT_COMPLETED action and start your service.
public class StartMyServiceAtBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent serviceIntent = new Intent("com.myapp.MySystemService");
context.startService(serviceIntent);
}
}
}
And now your service should be running when the phone starts up.
