android--广播和service

广播发送

String actionString = "com.androidbook.intens.testbc";
Intent broadcastIntent = new Intent(actionString);
broadcastIntent.putExtras("message","Hello World");
this.sendBroadcast(broadcastIntent);

广播接收

private static final String tag = "TestReceiver";

public onReceive(Context context, Intent intent)
{
          
         Utils.logThreadSignature(tag);
         Log.d("TestReceiver","intent="+intent);
         String message = intent.getStringExtras("message");
         Log.d(tag,mesage);      
}

Utils类记录运行接收程序代码的线程的签名。

public class Utils
{
   public static long  getThreadId()
   {
       Thread t = Thread.currentThread();
       return t.getId();
   }
   public static String getThreadSignature()
  {
       Thread t = Thread.currentThread();
       long l = t.getId();
       String name = t.getName();
       long p = t.getPriority();
       String gname = t.getThreadGroup().getName();
       return (name+“id”+1+"priority"+p+":group"+gname);
   }
   public static void logThreadSignature(String tag)
   {
        Log.d(tag, getThreadSignature());
   }
}
