That's odd. Those error dialogs are always supposed to generate Java
stack traces, AFAIK.

The following is extremely hackish untested psuedoJava, suitable only
for short-term use in emergency situations involving Christians and
Galaxies:
File rootDir=new File(getFilesDir(), "..");
File dbDir=new File(rootDir, "databases");
File db=new File(dbDir, "yourdatabasenamehere");
if (!db.exists()) {
File sdDb=new File(Environment.getExternalStorageDirectory(),
"yourdatabasenamehere");
// insert binary file copy algorithm here, from sdDb to db
}
// open and use your database as normal
where the binary file copy algorithm could be:
http://exampledepot.com/egs/java.io/CopyFile.html
This presumes you put a working copy of your database in
/sdcard/yourdatabasenamehere via DDMS or adb push or mounting the SD
card in your desktop environment or whatever.
This is NOT a great way of doing this sort of thing for production, but
for the purposes of a soonish demo, it just might work.
