Dear All,
I am now reading contentProvider.java( under the base/core/java/android/content)
Ln 127 looks following:
public Cursor query(Uri uri, String[] projection,
String selection, String[] selectionArgs, String sortOrder) {
enforceReadPermission(uri);
return ContentProvider.this.query(uri, projection, selection,
selectionArgs, sortOrder);
}
I'm really confused about that contentProvider invoke this.query()
Ln 444
public abstract Cursor query(Uri uri, String[] projection,
String selection, String[] selectionArgs, String sortOrder);
Ln444 is Nothing to do the query(....), it seams this is only declare,
not yet implement.
where is it implement? How can i find it? anyone can tell me?
