How to get installed applications permissions

问题:

I need to develop an android application to detect malwares.

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

You can get all installed applications permissions like this.

• 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();
   }
}

You can use this REST API to get details about an app, including permissions required by the app. For instance, to see what permissions WhatsApp is requiring, locate the "permissions" node in the response from this GET request: http://playstore-api.herokuapp.com/playstore/apps/com.whatsapp

More notes about how to make API calls for this could be found on the GitHub page.
