基本功能: 获取设备上所有应用的开机启动完成的广播接收者,同时区分系统应用和用户应用.
然后,提供界面接口给用户,统一管理应用的自启动功能,这样可以提升系统的运行性能和待机时长;

获取所有receivers 区分是否使能

获取包含被禁止自启动receiver的信息

1
List<ResolveInfo> forbidInfoList = mPackageManager.queryBroadcastReceivers(intent,PackageManager.GET_DISABLED_COMPONENTS);

获取所有使能的 receivers

1
List<ResolveInfo> allowInfoList = mPackageManager.queryBroadcastReceivers(intent,PackageManager.GET_RECEIVERS);

两个列表比较,标志receivers是否开启

for(int k=0; k<allowInfoList.size(); k++){
	if( allowInfoList.get(k).activityInfo.packageName.equals(packageName) ){
		isEnable =true;
	}
}

判断是否为系统应用

通过ApplicationInfo.FLAG_SYSTEM标志,判断是否为系统应用

if((forbidInfoList.get(i).activityInfo.applicationInfo.flags&ApplicationInfo.FLAG_SYSTEM)==1||  
(forbidInfoList.get(i).activityInfo.applicationInfo.flags&ApplicationInfo.FLAG_UPDATED_SYSTEM_APP)==1){
	isSystem = true;
}

判断是否运行并获取内存占用大小

float memUsed = 0;
ArrayList<Integer> pid = new ArrayList<Integer>(runningApps.size());
//循环处理正在运行进程
for(int k=0; k<runningApps.size(); k++){
	if(runningApps.get(k).processName.equals(packageName)){
		// Log.e("ycltest","in runningApps list find the right process,handle it");
		pid.add( Integer.valueOf(runningApps.get(k).pid) );
	}else{
		continue;
	}
}
if( pid.size() == 0){
	isRun = false;
}else{
	//获取内存大小
	isRun = true;
	int[] pids = new int[pid.size()];
	
	for (int num=0; num<pid.size(); num++) {
		pids[num] = pid.get(num).intValue();
	}
	Debug.MemoryInfo[] mi = mActivityManager.getProcessMemoryInfo(pids);
	for (int num=0; num<mi.length; num++) {
		memUsed += (float)(mi[num].getTotalPrivateDirty()+mi[num].getTotalPss())/1024;
	}
}

关闭和开启Receiver

通过PackageManager.setComponentEnabledSetting方法,关闭和开启Receiver

	int newState = isChecked ? PackageManager.COMPONENT_ENABLED_STATE_ENABLED : PackageManager.COMPONENT_ENABLED_STATE_DISABLED;
	for (int i=0; i<packageReceiverList.length; i++) {
		if( packageReceiverList[i] != null ){
			ComponentName comName = new ComponentName(item.getPackageName(), packageReceiverList[i]);
			int flag = 0;
			if( item.getPackageName().equals("com.android.settings") ){
				flag = PackageManager.DONT_KILL_APP;

			mPackageManager.setComponentEnabledSetting(comName,newState, flag);
		}
	}
}

其他功能

其他功能包括,列表排序,列表更新,无应用列表图片显示等,不在这里详细展开!
