Android Question DirDefaultExternal and GetSafeDirDefaultExternal

[William Hunter]

This is my first experience with the new runtime permissions. I am using KeyValueStore to store settings info in File.DirDefaultExternal. I want to make “datastore” available over SDK versions 16 to 25. Below is how I am attempting to do this. Is this the correct way, or should I handle this differently? Any help greatly appreciated.

Regards

If FirstTime Then
    kvs.Initialize(File.DirDefaultExternal, "datastore")
    rp.CheckAndRequest(rp.PERMISSION_CAMERA)
    rp.CheckAndRequest(rp.PERMISSION_RECORD_AUDIO)
    rp.GetSafeDirDefaultExternal("datastore")
End If

Added this to manifest.

<uses-permission
  android:name="android.permission.WRITE_EXTERNAL_STORAGE"
  android:maxSdkVersion="18" />

EDIT: This seems to work, but DirInternal might be just as good.

If FirstTime Then
        Dim Dir As String = rp.GetSafeDirDefaultExternal("") 'safe dir device dependent
        kvs.Initialize(Dir, "datastore") 'init keyvaluestore
        rp.CheckAndRequest(rp.PERMISSION_CAMERA)
        rp.CheckAndRequest(rp.PERMISSION_RECORD_AUDIO)
End If

Your code is correct. If the camera is not needed immediately when the program starts then it is better to ask for the permission later when it is required.
