I am looking to develop this based on permissions used by all the applications installed. Please let me know how to identify the permissions used by other applications

推荐答案

您可以像这样获得所有已安装的应用程序权限.

You can get all installed applications permissions like this.

• 获取所有已安装的应用程序
• 迭代应用程序
• 获取每个应用的权限列表
• 迭代每个权限

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();
   }
}
