for Lock Screen programmatically using Android. I got some good ideas from Stackoverflow previous questions regarding this, and I did some thing well, but when I run that code, there is No Exception and Error. but also , the screen didn't lock. kindly some one point my fault in this code

I can't find what is goes wrong here. kindly help me to point out my mistake here. thanks in advance.
you can add this code into your Activity class, it's works fine for me
if(!mDPM.isAdminActive(mAdminName))
{
intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,"is locked");
intent.putExtra("force-locked", DeviceAdminInfo.USES_POLICY_FORCE_LOCK);
startActivityForResult(intent, 1);
System.out.println("The Device Could not lock because device admin not enabled");
//mDPM.lockNow();
}
else
{
System.out.println("The Device device admin enabled");
intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,"onEnabled");
mDPM.lockNow();
mDPM.setMaximumTimeToLock(mAdminName, 0);
intent.putExtra("force-locked", DeviceAdminInfo.USES_POLICY_FORCE_LOCK);
startActivityForResult(intent, 1);
}
Hope this would be helpful for you.

please help me I try everything on internet but There are no results I think this problem about permission what can I do in manifest file help me I want it this broadcast recieve to work at startup :(
The docs say:
This is a protected intent that can only be sent by the system.
https://developer.android.com/reference/android/content/Intent#ACTION_BOOT_COMPLETED
Which means that you cant send this intent.
You currently have <action android:name="android.permission.BOOT_COMPLETED" /> set as an intent filter, which won't work.
Add <action android:name="android.intent.action.BOOT_COMPLETED" /> to the intent filter of your SensorRestarterBroadcastReceiver, then reboot your device.
I've tried:
This which doesn't work on my phone:
Trying to start a service on boot on Android
This which also fails to work properly:
http://www.compiletimeerror.com/2014/12/android-autostart-app-after-boot-with.html#.VpL6sxWLTIU
And a few others which I couldn't find again. Could someone please post a working example of code which will start a MainActivity with the default HelloWorld xml layout?
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >

<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<activity
android:name=".MyService"
android:label="#string/title_activity_my_service" >
</activity>
</application>
</manifest>
package com.example;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, MyService.class);
context.startService(startServiceIntent);
}
}
package com.example;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MyService extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_service);
}
}
First：create a BroadcastReceiver, onReceive(Context context, Intent intent)，start the app you want to startup in this method
public class BootBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
xxx.class is the app you want to start
Intent service = new Intent(context,XXXclass);
context.startService(service);
Log.v("TAG", "you want to startup this app.....");
Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);
context.startActivity(intent );
} }
Secondly:configure receiver and intent-filter
<receiver android:name="BootBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>
THirdly,add permission
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
The function doWork maybe run 20s, I think the system will cause ANR problem.
I don't know what kind of technology I need use to prevent ANR, AyncTask, local server, thread, IntentService or others.
Could you give me some sample codes? Thanks!

I need to start 2 services on bootcompleted. The first service starts correctly, but second service seems is not starting.
I don't know if I have to create two BroadcastReceiver or it's enough with one.
Here is my code. I've put the two services in one BroadcastReceiver. Please, can you tell me what I'm doing wrong?
Thank you in advance

I am trying to display messages from C2DM so When I start an Activity from a non activity it works but only first time. My activity contains View and close button so if the user is not inside the app when he receive the push notification then it should start the app when he press view button or close it on close this works as well but when user press view button and enters the app after than I am unable to start the activity again, it seems like the activity is there but its not visible to user. My code is as below , hope you understand what I am saying. The C2DM code example used is taken from here

If i remove androidLaunchMode singleTop form manifest file and add set flag to multipleTask in C2DMReciver class it works but i get lots of dialog for each message. Thanks for help .
Set flag to singletop , the code to call messagedialogactivity is as under:
Intent intent = new Intent();
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setClass(context, MessageDialogActivity.class);
