Android Question Need android.permission.BLUETOOTH_CONNECT in android 12

[ppgirl]

Dear Erel,

Now (Sept. of 2022), Android 12 is Google Play basic requirement. I need update my app with Bluetooth function to Android 12.
I found the permissions about bluetooth add "android.permission.BLUETOOTH_SCAN" ,"android.permission.BLUETOOTH_CONNECT" and "android.permission.BLUETOOTH_ADVERTISE" in API31. Using the API31 , App will not connect if has not "android.permission.BLUETOOTH_CONNECT" permission.
I try to use rp.CheckAndRequest("android.permission.BLUETOOTH_CONNECT") to call the RuntimePermissions page , but it looks no function.
So I want know the right way to call those new runtime permissions , Thanks in advance!

When asking questions please do not address them to an individual unless it is absolutely necessary.

Have you tried putting the following in your manifest?

AddPermission(android.permission.BLUETOOTH_ADVERTISE)
AddPermission(android.permission.BLUETOOTH_CONNECT)
AddPermission(android.permission.BLUETOOTH_SCAN)

@agraham , you are friendly.

I have added those in manifest editor, there are lines in the AndroidManifest.xml.
...
<uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE"/>
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT"/>
<uses-permission android:name="android.permission.BLUETOOTH_SCAN"/>
...

PS, This is the log of connect failure.
java.lang.SecurityException: Need android.permission.BLUETOOTH_CONNECT permission for android.content.AttributionSource@331e1d8b: HidDeviceService$BluetoothHidDeviceBinder

No further ideas - sorry. As I understand it they are normal runtime permissions so you should get them when you call rp.CheckAndRequest unless the user refuses it. You should know this from the PermissionResult event. Are you getting the permission page displayed?

@agraham,

I find my bug and the CheckAndRequest work right.

I make connecting before "Wait For Activity_PermissionResult" event , so the connecting is failure.

public Sub checkConnectPermission
...
rp.CheckAndRequest("android.permission.BLUETOOTH_CONNECT")
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
If Result = False Then
ToastMessageShow("No permission, The App is about to EXIT!", False)
Activity.Finish
End If
...
end sub

public Sub main
...
checkConnectPermission
connect()
...
end sub

I've recently updated the BT example with the new permissions: https://www.b4x.com/android/forum/threads/b4xpages-bluetooth-chat-example.119014/
