Android Question java in class module

Im having an issue with jave code in a class module, which works fine in an activity module.

End Sub
javac 1.8.0_111
src\b4a\RELEASE\startcar.java:361: error: cannot find symbol
WifiManager mw = (WifiManager) getSystemService(Context.WIFI_SERVICE);
^
symbol: method getSystemService(String)
location: class startcar

here's the code:

#If JAVA
import android.net.wifi.*;
import android.content.Context;
import java.util.List;
import java.lang.Object.*;
import android.widget.Toast;

public boolean ison ()
{

WifiManager mw = (WifiManager) getSystemService(Context.WIFI_SERVICE);

return mw.isWifiEnabled();

}

Thanks

The Wifimanager needs an context i guess...

So i think it will only work in an activity or an service as these runs the inline java in it´s own context.

Maybe you need to give the Activities context to the class (when initialing for ex) and then use this context. But then i think it would be better to place the java directly in the activity.

I didn´t do much with inline java so i cant´t help more on this.

After 5 hours i figure it out by adding

Context context = BA.applicationContext;


WifiManager mw = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

It works.

I tried using mlwifi library buts its buggy and didnt work, that prompted me to check his source code. From there I figured it out.
