Execute "strict" queries with extra parentheses.
SQLiteQueryBuilder has a setStrict() mode which can be used to
detect SQL attacks from untrusted sources, which it does by running
each query twice: once with an extra set of parentheses, and if that
succeeds, it runs the original query verbatim.
This sadly doesn't catch inputs of the type "1=1) OR (1=1", which
creates valid statements for both tests above, but the final executed
query ends up leaking data due to SQLite operator precedence.
Instead, we need to continue compiling both variants, but we need
to execute the query with the additional parentheses to ensure
data won't be leaked.
