I am having an issue reading from a KeyValueStore directly after copying the associated filed from assets to the internal directory. Any read or write after that initial copy works as it should even when the program is re-run or a new version of the program is generated.
When the program is run for the first time, it checks to make sure the file is in the internal directory. If it is not, it copies it from assets to the internal directory. In the error below, I logged the keys stored in the file, so I know the file was copied and is open and it contains the keys at least.
My data are user types as follows:
Here is the error:
** Activity (main) Create, isFirst = true **

** Activity (main) Resume **
If I continue running, all values from the file are set to zero so I assume no values were actually read. But from here on out, I can update and read data from the file correctly even when the program terminates and re-runs. This error only shows up on a fresh install the first time it is run.
Any help on this would be greatly appreciated, I assume I am doing something boneheaded
