Hey, I attached a couple of our java classes that perform this function. I
had to clean up a bit and remove the package names, but i'm sure that won't
slow you down :-)
here is the database table definition:
buf.append("CREATE TABLE ").append(DbMetadata.TABLE_DEBUG
).append(" (");
buf.append(DbMetadata.DEBUG_TIME).append(" INTEGER, ");
buf.append(DbMetadata.DEBUG_TYPE).append(" TEXT, ");
buf.append(DbMetadata.DEBUG_PACKAGE).append(" TEXT, ");
buf.append(DbMetadata.DEBUG_MESSAGE).append(" TEXT)");
