Version 2.16.2

Update target sdk:
- The targetSdk version has been updated to 34.

Version 2.16.1

Improves the performance of the open() function of the NcgEpubFile class:
- If there are A1.ncg, A2.ncg, A3.ncg, ... etc. inside the AAA.epub file, it is faster to read the A2 and A3 files because the DRM header is read only when the A1.ncg file is opened for the first time.

Version 2.13.0

What's New in Version 2.13.0

Added You can register callbacks for Local File

LocaFileCallback allows you to register callbacks to access and use local files internally in the SDK, allowing for intermediate processing in your app.
You can register a callback using the setLocalFileCallback(LocalFileCallback callback) function.
LocalFileCallback
- Boolean fileOpen(String filePath, String openMode, int cloneNum)
- void fileClose(int cloneNum)
- byte[] fileRead(long numBytes, int cloneNum)

Version 2.12.2

What's New in Version 2.12.2

Added New parameter for the init function.

init(Context context, OfflineSupportPolicy policy, String deviceID, String roDbPath, String prefixPreferenceName, boolean isFirstCallAfterBoot)
From now on, prefixPreferenceName has been added to the init function parameters.
The prefixPreferenceName parameter allows you to change the SharedPreference name being used inside the SDK.
However, if you set prefixPreferenceName in init, you need to set prefixPreferenceName when using DeviceManager.

Added Added Builder pattern when creating DeviceManager

From now on, you can create it using the Builder pattern, and you can set the prefixName.
If you set the prefixPreferenceName in init, you need to set the same prefixName when using DeviceManager.

Version 2.12.1
