    Sub Activity_Create(FirstTime As Boolean)
    Dim NativeMe As JavaObject
    End Sub
    #If JAVA
    import android.content.Intent;
    import android.provider.Settings;
    public void turnGPSOn()
      Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
      intent.putExtra("enabled", true);

      String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
      if(!provider.contains("gps")){ //if gps is disabled
      final Intent poke = new Intent();
      poke.setClassName("", "");

    #End IF
    It doesn't work (as expected).

    Of course I read. The first method needs root and the second one is not working on newer devices.

    At my link's code they say that it works and no mention about root.

    Wow, you were so fast Erel! :D Thanks, I will try it too.

    I have also tried Erels code, which is the code from your stackoverflow thread as inline java code - that is a realy awesome method in the new b4a!! - but it didn't work. I think the device must be also rooted. The log say's something like this: Caused by: java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.location.GPS_ENABLED_CHANGE from pid=21326, uid=10107

    I checked the method on some devices and results are mixed. It worked on rooted phones with 4.0.3 and 4.3. There was a positive result too on a 4.1.2 without root and a negative on 4.4.2. Last one give an error code: "An error has occured in sub: java.lang.reflect.InvocationTargetException" I think it is a different error than Eurojam's, isn't it?

    Eurojam, on which version have you tried?
