开关机压力测试APK学习

        楼主身在一个手机方案公司，最近在查看一个开关机压力测试的APK，记录一下，学习一下别人的代码。功能单一，代码简单，谢谢！

布局界面较简单，一个ListView里面含有三个Textiew，一个设置总的重启次数，一个重启开关，一个用于显示标记已经重启的次数。这里就不写出了。

程序代码比较简单。此外还有一个java文件。

package com.zh.reboot;

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.util.Log;

public class BootBroadcastReceiver extends BroadcastReceiver {
	/** Called when the activity is first created. */
	static final String ACTION = "android.intent.action.BOOT_COMPLETED";//开机就启动，接收这个ACTION，检测是否需要继续开关机测试
	private String TAG = "Reboot";

	@Override
	public void onReceive(Context content, Intent intent) {
		// TODO Auto-generated method stub
		if (intent.getAction().equals(ACTION)) {
			SharedPreferences sp = content.getSharedPreferences("datafile",
					Context.MODE_PRIVATE);
			int count = sp.getInt("count", 0);
			int needreboot = sp.getInt("need_reboot",
					mainActivity.NOT_NEED_REBOOT);
			int totalnum = sp.getInt("totalnum", -1);
			Log.d(TAG, "count:" + count + " need_reboot:" + needreboot
					+ " totalnum:" + totalnum);
			if (count != 0 && needreboot == mainActivity.NEED_REBOOT
					&& count != totalnum) {
				Intent AutoRebootIntent = new Intent(content,
						mainActivity.class);
				AutoRebootIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
				content.startActivity(AutoRebootIntent);
			}
		}
	}
}

相关部分已经说明，很好理解。欢迎留言。留做标记，以后好找。
