Android Question reading an email account with Android 8.0

[pesquera]

Hi everyone,

I have been used this code for a long time without any issue.. now, I have an error on Android 8

The code:

Dim r As Reflector
r.Target = r.RunStaticMethod("android.accounts.AccountManager", "get", _
      Array As Object(r.GetContext), Array As String("android.content.Context"))
Dim accounts() As Object
accounts = r.RunMethod2("getAccountsByType","com.google", "java.lang.String")
r.Target = accounts(0) ' read the first record
loc_ToRetun = r.GetField("name")

The app crash on this line:

r.Target = accounts(0) ' read the first record

The debug:

Error occurred on line: 267 (zzUtil)[/COLOR][/FONT][/LEFT]

Could it be related to permissions? Witch one?

Thanks all​

Account access and discoverability
In Android 8.0 (API level 26), apps can no longer get access to user accounts unless the authenticator owns the accounts or the user grants that access. The GET_ACCOUNTS permission is no longer sufficient. To be granted access to an account, apps should either use AccountManager.newChooseAccountIntent() or an authenticator-specific method. After getting access to accounts, an app can can call AccountManager.getAccounts() to access them.

thanks @DonManfred

I'm not advanced on this issues

I found this code:
https://www.b4x.com/android/forum/threads/how-to-translate-java-accountpicker-to-b4a.89900/#content

I'm trying to replace that code with this one.. thanks again!

Sorry, I don´t know how to implement this on B4A

You did found the right thread i think.

Start using the Accountpicker Code Erel posted.
Once you get access you can try to reuse your old GET_ACCOUNTS Code.

After getting access to accounts, an app can can call AccountManager.getAccounts() to access them.

How did you get this working. I tried Erel's code and it crashes.

Need to verify the user has an Email Account setup


Found this code by Erel that gets me the Emails

  Dim r As Reflector
  Dim wAccounts As Map
  wAccounts.Initialize
  r.Target = r.RunStaticMethod("android.accounts.AccountManager", "get", Array As Object(r.GetContext), Array As String("android.content.Context"))
  Dim accounts() As Object
  accounts = r.RunMethod("getAccounts")
  For i = 0 To accounts.Length - 1
  r.Target = accounts(i)
      wAccounts.Put(r.GetField ("name"), "")
  Next
  For Each account As String In wAccounts.Keys
     Log(account)
   Next

The only problem is it always seems to return just 1 Email and I have multiple
