I'm creating a custom plugin. The plugin worked fine as a standalone app - but when I add the code to an existing BT app, I am running into problems. I am constructing items such as TextView, TableRow + other items as follows: TextView tv = new TextView(this); Eclipse is not liking the lack of context in "this". Searching the web I can see I should alter the code to: TableRow row = new TableRow(context.this); But I can't work out what "context" is in a BT 3.0 app. Any ideas? NB. The working code in the standalone app started with public class MainActivity extends Activity { but this was changed in the BT app to public class myCustomPlugin extends BT_fragment{

I believe (this) is (getactivity)) .. or something of that nature. I'm not in front of my computer but I'm sure the Android experts will chime in soon!

>But I can't work out what "context" is in a BT 3.0 app. You are in for a funny ride. Most of the code you find on GitHub is for activities, while BT 3.0 for Android is based on fragments. "this" is a set of variables for one module, or class or package, or app... For an activity, "this" will serve just fine, it is giving you all the variables that you defined after the definition of the class. In BT 3.0 there is one app, and one class on which everything is based, and everything else is a fragment on top of that class. So, using "this" in BT will refer to that class, and not to the variables that you defined in the class section. So, how to use it? First you have to have this: import android.content.Context; then define public static Context context; in your class. Then in the beginning of your onCreateView method put the following: context = getActivity().getApplicationContext(); Instead of "this" use context and 90% of time you are good.

Perfect Dusko ;)

Thanks Dusko I'll give it a try when I'm back home and report back - but it sounds gd to me.

Yes Dusko - that worked perfectly. Thank you.

Yeah you don't need to put "this" so just declare the variable without using "this". LA
