android - 如何获取已安装的应用程序权限

Question

我需要开发一个 Android 应用程序来检测恶意软件。

我希望根据所有安装的应用程序使用的权限来开发它。请告诉我如何识别其他应用程序使用的权限

Answer 1

您可以像这样获取所有已安装的应用程序权限。

• Get all installed applications
• Iterate over the applications
• Get each application permissions list
• Iterate over the each permission

PackageManager pm = getPackageManager();
List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);

for (ApplicationInfo applicationInfo : packages) {
   Log.d("test", "App: " + applicationInfo.name + " Package: " + applicationInfo.packageName);

   try {
      PackageInfo packageInfo = pm.getPackageInfo(applicationInfo.packageName, PackageManager.GET_PERMISSIONS);

      //Get Permissions
      String[] requestedPermissions = packageInfo.requestedPermissions;

      if(requestedPermissions != null) {
         for (int i = 0; i < requestedPermissions.length; i++) {
            Log.d("test", requestedPermissions[i]);
         }
      }
   } catch (NameNotFoundException e) {
      e.printStackTrace();
   }
}
