APK:强制apk栈顶

需求：

1、每隔60秒判断当前apk是否在当前页面，否就拉起来

2、收到开机广播，延迟启动服务

MyBroadcast.java

package com.gatsby.galway;

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

public class MyBroadcast extends BroadcastReceiver {

    Context mContext;
    static final String BOOT_COMPLETED = "android.intent.action.BOOT_COMPLETED";

    Handler mhandler = new Handler();

    private Runnable runnable = new Runnable() {
        @Override
        public void run() {
            Log.d("gatsby", "Handler  DelayRunable!");
            Intent startService = new Intent(mContext, BootService.class);
            mContext.startService(startService);
        }
    };

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        this.mContext = context;
        String action = intent.getAction();

        if (action.equals(BOOT_COMPLETED)) {
            Log.d("gatsby", "CrushBroadcast BOOT_COMPLETED -----------!!!!");
            mhandler.postDelayed(runnable, 120000);
        }
    }

}
