Question

Is there anything like asp.net transactions in Android SQLite? I am doing some processing on an SQLite database from my Android code, but I want upon failure to rollback the transaction and return the database to it’s original state before the processing started.

Can this be achieved?

thanks

It’s already there in the methods provided by the framework.

Check the SQLiteDatabase class docs here.

Specifically what you want are the *WithOnConflict methods and use the constant CONFLICT_ROLLBACK in said methods.

When a constraint violation occurs, an immediate ROLLBACK occurs, thus
ending the current transaction, and the command aborts with a return
code of SQLITE_CONSTRAINT
