Major Description
I have code that will reliably produce a "Corrupt database" error.
- Unpack a zip file into a very large database (provided by a forum poster), to Android external storage
- Run an integrity check on the DB. It passes
- Attempt to copy the database from external storage to internal storage (Database.copy) Copy fails with the corrupt data message
- Run an integrity check on the DB. It passes
After the attempted copy, the source database directory looks like this:
27|shamu:/sdcard/Android/data/com.couchbase.android.corruption/files/crash_test_dummies/testdb.cblite2 # ls -al

The size of the .sqlite file seems about right.
The target directory is empty.
Here is the debug-level log for the failure:
