!!画面のON、ＯＦＦの変化を受け取る

 <action android:name="android.intent.action.ACTION_SCREEN_OFF"/>
 <action android:name="android.intent.action.ACTION_SCREEN_ON"/>
を入れても受け取れない。プログラムで仕掛ける必要があるみたい。
 getApplicationContext
を使わなくても動くようだけど、素直にgetApplicationContext使った方が良いかも。

!ScreenOff.java
{{code Java,
package test.screenoff;

import android.app.Activity;
import android.os.Bundle;
import android.content.*;

public class ScreenOff extends Activity
{
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    
    IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
    this.getApplicationContext().registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
          System.out.println("onReceive 2");
        }
    }, filter);
    
    filter = new IntentFilter(Intent.ACTION_SCREEN_OFF);
    this.getApplicationContext().registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
          System.out.println("onReceive 3");
        }
    }, filter);
  }
}
}}

!AndroidManifest.xml
  <?xml version="1.0" encoding="utf-8"?>
  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
