What part of App is considered Context? The java file, the .xml, or a part of one or the other?

Question

I've been trying to access images from my assets folder now instead of drawable in order to possibly alleviate some memory issues I'm having.

I found this code to aid with this:

public static Drawable getAssetImage(Context context, String filename) throws IOException {
    AssetManager assets = context.getResources().getAssets();
    InputStream buffer = new BufferedInputStream((assets.open("drawable/" + filename + ".png")));
    Bitmap bitmap = BitmapFactory.decodeStream(buffer);
    return new BitmapDrawable(context.getResources(), bitmap);
}

I'm confused what the context is though. Am I to pass it my MainActivity.java? Or reference it to a specific view? If anyone could explain this I would much appreciate it.

Yes, you can just pass your activity from which you are invoking this method.

getAssetImage(MainActivity, "pilots_cropped_edited.png"); – Michael Philipps Oct 20 '16 at 18:22
so I'm in my MainActvitiy, but it says "expression expected" where I put in MainActivity. What part of the activity is it expecting. @Roman Samolyenko – Michael Philipps Oct 20 '16 at 18:23
use `MainActivity.this`. if it is in an activity. If it is a fragment. use `getContext()` – M.Waqas Pervez Oct 22 '16 at 06:15
