Access Context in ContentProvider

Question

I have a ContentProvider Class and a DatabaseHelper Class (extends SQLiteOpenHelper). The ContentProvider instantiates the Helper which needs access to a Context because the constructor requires it:

public DBHelper(Context context, AssetFileDescriptor db_asset) {
    super(context, DB_NAME, null, 1);

Do you know at least a single way to get the Context from the ContentProvider?

Thanks :)

Solution 1

In your ContentProvider.onCreate method you can pass the result of getContext() to the DBHelper

    @Override
    public boolean onCreate() {
        dbHelper = new DBHelper(getContext(), db_asset);
        return true;
    }

Solution 2

Do you know at least a single way to get the Context from the ContentProvider?

ContentProvider:getContext()

Solution 3

Try this my friend:

SampleClass sample = new SampleClass(this.getContext());

Where this refer to the class that extends the ContentProvider... And .getContext() will get the context of the class that extends the ContentProvider..

Hope this one helps..

thanks, I was focused on passing "this" as usual with constructors, didn't get the Idea to try something that trivial :)

"focused on passing this" - you should pass application context instead of activity context to prevent memory leaks, see this post.

Well, Julian, it's not your fault if there is not much of a consistency in "this", "getActivity()", "getContext()", etc. use.
