Read PDF file from SharePoint in android via graph api with java.

Question

Its my first time to work with MSAL.

i am using the graph api to read data but i'm getting a sharepoint file link .

i want to download that file into my app but it is giving 403 error code (with using MSAL auth token) but i can access that file without login with that url on chrome or any other browser .

Q1 is there any special permission required to access share point file on android ?

My Permissions :

Q2 can someone share sample auth json file or manifest file ?

i am using this auth json file.

{  "client_id" : "xxxx", 
 "authorization_user_agent" : "DEFAULT", 
 "redirect_uri" : "msauth://com.example.xxxx",  
"account_mode" : "SINGLE",
  "broker_redirect_uri_registered": false,
  "shared_device_mode_supported": true, 
 "authorities" : [  
  {      "type": "AAD",   
   "audience": {        "type": "AzureADandPersonalMicrosoftAccount",  
      "tenant_id": "common"      }   
 }  ]}

Q3 Any example to read file in android java or kotlin ?

This is my REST call with retrofit client.

@Streaming
@GET
fun downloadPdf(  
  @Url urlPdf: String,   
 @Header("Authorization") token: String,): Call<ResponseBody>

Hi @Sakshi Sharma,

You will need sites.readall permission to view the PDF file from SharePoint in android. It's same as the permission on other environment. For the samples in MSAL you can refer to the document

And since our forum is focus on C#. You can raise a new ticket in techcommunity. You might get some more professional advice there.
