Hi~ tiqniya.

Registered issue are caused by the fact that the working directory has not been initialized.
From android version 6.0 higher, we need to acquire user confirm at runtime, but the working directory is initialized before the privilege is acquired therefore the diary card can not be created.
This problem can be solved by adding the work directory initialization method when generating the diary card after the authorization is completed.
Add the following code to PostCardActivity.java line 269 to generate the working directory to be initialized before calling the BitmapUtils.saveBitmapToFileCache method.
EasyDiaryUtils.initWorkingDirectory(Environment.getExternalStorageDirectory().getAbsolutePath() + Path.USER_CUSTOM_FONTS_DIRECTORY);

If you like, please request a 'pull request' after fixing the issue yourself. =)
