Answer 1

[WRONG:] No, it is not thread-safe by default. You shoud use locking-related SQLiteHelper methods to provide thread safety.

[EDIT]: SQLiteDatabase class provides a locking mechanism by default (see comments) and if you are running on multithread, you don't have to consider changing anything to have thread-safety.

Search for 'thread' in this document: http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html
