Maildroid got black screen problem.

Using MailDroid AD ver 2.14

Recently running MailDroid just got a black screen with the notification bar. If I press home button can switch to other apps, but if I press the back button the system will hang, and then it'll reboot in a short while.

I have to uninstall and reinstall it, then the first time can enter MailDroid interface and recover my accounts, next time I run MailDroid, black screen again.

Please help me, thanks~

Installing the old ver (2.10) is ok.

I am very lucky to find out the old ver(2.10) apk file, after installing v2.10, everything is OK.
