Android no such table (not found)

Today in the study project, has been error no such table Users. Said the users table could not be found. I was wondering, the database is copied in the past, check the table name is not written wrong. What's going on here? Check for half a day only to find that the original database path is wrong.

I copied the database to the SD card, but I used the Android to inherit the Sqliteopenhelper way in the Getreadabledatabase () method to get the database. As we all know, the default database path in Android is:/data/data/package name/databases/database name. Therefore, the Getreadabledatabase () method that comes with Android is also the database that is found by default path. So, to solve this problem, either copy the database to the default path, or write the database helper class yourself.

I chose the former.
