android点滴(6)之获取Android系统中所有的开机自启动项

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;

      }

}
