/* 备注： 
    通过 PackageInfo  获取具体信息方法：
包名获取方法：packageInfo.packageName
icon获取获取方法：packageManager.getApplicationIcon(applicationInfo)
应用名称获取方法：packageManager.getApplicationLabel(applicationInfo)
使用权限获取方法：packageManager.getPackageInfo(packageName,PackageManager.GET_PERMISSIONS).requestedPermissions
    通过 ResolveInfo 获取具体信息方法：
包名获取方法：resolve.activityInfo.packageName
icon获取获取方法：resolve.loadIcon(packageManager)
应用名称获取方法：resolve.loadLabel(packageManager).toString()
