I'm trying to download a file received in a one to one conversation. The method isFileDescriptorAvailable returns true for the message with the file but when I get the fileDescriptor, the methods getFile and getImagePreview returns null. And when I try to download the file with RainbowSdk.instance().fileStorage().downloadFile(),
I get the following error:

01-24 17:15:13.959 25867-25867/com.ale.conversationsdemo E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.ale.conversationsdemo, PID: 25867
java.lang.NullPointerException: file == null

at com.ale.infra.manager.fileserver.FileServerMgr.downloadFile(FileServerMgr.java:663)
at com.ale.rainbowsdk.FileStorage.downloadFile(FileStorage.java:33)

SDK version: 1.50.0

Thanks for your help

  Hello Maxime,

   

  Its seems that your app isn't allowed to have storage acces. You must add this permission in your manifest

   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

  like described in the "getting started" section of the documentation. 

  
  If your device has Android 6 or superior you also need to ask the user to accept this permission at runtime (or just for testing you can go in the parameters/application/your app/autorisations/ and activate the needed permission.

   

  Look at the official Android documentation for more information: Permissions
