使用AlarmManager搭配Receiver应该可以实现定时自动启动应用程序:
[java]
view plain
copy
- 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
- }
- }
[java]
view plain
copy
- 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);
- }
- }
[java]
view plain
copy
- <?xml version=“1.0” encoding=“utf-8”?>
- <manifest xmlns:android=“http://schemas.android.com/apk/res/android”
