Android定时自动启动应用程序

使用AlarmManager搭配Receiver应该可以实现定时自动启动应用程序：

import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class StartTiming extends Activity {
    
    public final String MYACTION = "android.intent.action.STARTMYAP";
    
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        Button btn = (Button)this.findViewById(R.id.btnClose);
        btn.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                StartTiming.this.finish();
            }
        });
        AlarmManager am = (AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(MYACTION);
        PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent, 1);
        am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+15000, pi);//15秒钟以后启动
    }
}
   

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class AlarmReceiver extends BroadcastReceiver
{
    public final String MYTAG = "Ray";
    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Log.v(MYTAG,"I am AlarmReceiver,I receive the message");
        Intent in = new Intent();
        in.setClass(context, StartTiming.class);
        in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(in);
    }
}
