"why should need context need as parameter." - It needs access to your app's internal files. — Mike M., May 23 '16 at 06:46
why needed constructor with the parameter on context... what resource is needed on that script ? — navotera, May 23 '16 at 06:49
Because `Context` is a God Object, you'll need it almost everywhere in Android. — klimat, May 23 '16 at 06:50

SQLiteOpenHelper needs a Context to create or open an existing database. It uses this method to do so. But you could have see it yourself by opening the source code of the class.

db = mContext.openOrCreateDatabase(mName, mEnableWriteAheadLogging ?
    Context.MODE_ENABLE_WRITE_AHEAD_LOGGING : 0,
    mFactory, mErrorHandler);

Context is used almost everywhere in Android, mostly for accessing application resources, as well as performing various operations.

I'm glad if it's clearer to you now. I just added a link to `SQLiteOpenHelper`'s source code as well. Cheers! – Eduard B. May 23 '16 at 06:59
