Question

In my android app, there are two processes, let’s say process A and B

It is funny that if process A tries to access the sqlite database, everything is fine.
However, if process B does so, following exception will be shown

android.database.sqlite.SQLiteException: unable to open database file:
BEGIN EXCLUSIVE;

FYI, actually not my app tries to use SQLite database. Instead, I use Google Analytics to track users and it uses SQLite database.

Why does this happen? Thank You.

Answer 1

Actually what you are using is Transaction.and when transaction is in progress no other process can access the database.

I think that is why you are getting this exception

Sometimes it happens

1. when beginTransaction is called on a not-open database connection.
2. when SQL statements contain syntax errors
