总结：

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()
