Checking if 'Unknown sources' is checked

[DKCERT]

Is it possible to check if "unknown sources" has been checked (set to true) using B4A code?

It seems like you can verify the status. Look here:

Settings.Secure | Android Developers

Maybe you can use Agraham's Reflection-library to access it?

No need for reflection, just use the phone library ie

Dim ph as Phone

if ph.GetSettings("install_non_market_apps") = 1 then 'can install from other sources

Thanks Moster67,

I have this Sub...

Sub GetAndroidId As String
   Dim p As Phone
   Return p.GetSettings("android_id")   
End Sub

... that I changed to this:

Sub GetAndroidUnknownSourceStatus As String
   Dim p As Phone
   Return p.GetSettings("install_non_market_apps")   
End Sub

It seems to work

Argh BlueJay... I had the edit window open and didn't see your post. Thanks a lot - that confirms my own code triggered by Moster67

Great! I was not even aware about the GetSettings-method. Thanks.

This post helps me a lot
And if the value is false "cannot install from unknown sources", how to call up the option setup page for user to change this option?
