     startActivity(intent);

打开设置中心:

Intent intent = newIntent(

              "android.settings.APPLICATION_DETAILS_SETTINGS");

         intent.setData(Uri.parse("package:" +clickBean.getPackName()));

         startActivity(intent);

卸载软件:    用户软件          

Intent intent = newIntent("android.intent.action.DELETE");          

intent.addCategory("android.intent.category.DEFAULT");

     intent.setData(                 

     Uri.parse("package:" +clickBean.getPackName())); 

     startActivity(intent);//

系统软件:

try {        //判断是否root刷机

         if(!RootTools.isRootAvailable()) {

              Toast.makeText(getApplicationContext(),"请先root刷机",0).show();

              return;

         }   //是否root权限授权给当前apk

         if(!RootTools.isAccessGiven()) {

              Toast.makeText(getApplicationContext(),"请先root刷机",0).show();

              return;

         }   //直接可以使用命令删除apk

         RootTools.sendShell("mount -o remount rw /system", 8000);//设置命令的超时时间为8秒

         System.out.println("安装路径:" + clickBean.getApkPath());

         RootTools.sendShell("rm -r " +clickBean.getApkPath(), 8000);

         RootTools.sendShell("mount -o remount r /system", 8000);

} catch (Exception e) {
