获取Android系统中所有的开机自启动项
绿水本无忧，因风皱面；青山原不老，为雪白头。
思路：
a.获取系统中安装的所有的应用程序的信息(ApplicationInfo)
b.检查应用程序的Permission中是否有RECEIVE_BOOT_COMPLETED
需要使用PackageManager，ApplicationInfo类，
PM类的文档如下：
Class for retrieving various kinds of information related to the application packages that are currently installed on the device. You can find this class through getPackageManager().
中文：PM类可以用来获取安装在设备上的应用程序包相关的各种信息。可以通过getPackageManager()获取对象。
ApplicationInfo类的文档如下：
Information you can retrieve about a particular application. This corresponds to information collected from the AndroidManifest.xml's <application> tag.
中文：使用ApplicationInfo类你可以返回关于一个特定的应用程序的信息。这些信息是从AndroidManifest.xml的<application>标签收集来的。
例子：
public class BootAppEnumUtils {
private Context mContext;
private static final String permName = "android.permission.RECEIVE_BOOT_COMPLETED";
public BootAppEnumUtils(Context context){
this.mContext = context;
}
public List<String> listBootApps(){
List<String> bootAppNames = new ArrayList<String>();
PackageManager pm = mContext.getPackageManager();
//获取所有安装的App的信息
List<ApplicationInfo> appInfos = pm.getInstalledApplications (PackageManager.GET_UNINSTALLED_PACKAGES);
for(ApplicationInfo appInfo : appInfos){
int iBoot = pm.checkPermission(permName, appInfo.packageName);
if(iBoot == PackageManager.PERMISSION_GRANTED ){
String appName = pm.getApplicationLabel(appInfo).toString();
bootAppNames.add(appName);
}
}
return bootAppNames;
}
}
