FC on Lollipop when opening

[SanderGit]

When opening Move Certs! on Lollipop (5.0.1) on a HTC One M7 GPE, the app immediately crashes. It has been granted root (after 2 tries it prompted for it) but did not help. Just purchased version 1.0.2 from the Play Store.

This app is based on a hack, which doesn't seem to work with your phone.

Unfortunately, there's nothing I can do about this, but if anyone finds a similar, working hack, I'll happily implement that.

It likewise immediately quits on a Samsung Galaxy S7.

The problem seems to be that some manufacturers moved the user certificate store to a different folder. Unfortunately I don't have any of the affected devices. If you can find the new path on your device, I'll implement that.

on my S5+ with new Marshmallow the app also crashes on startup. With Lollipop it was working.... I checked the folder /system/etc/security/cacerts/ and it still exist and has files inside. I think it would be a good idea to catch the crash at startup and display a message depending on the error (path xy could not be opened for reading or what ever..)

okay, i search in your code for paths and found where you are searching for user cert:

https://github.com/Nutomic/movecerts/blob/master/app/src/main/java/com/nutomic/zertman/CertificateManager.java

On Marshmallow/S5+ the user certs moved to: /data/misc/keystore/user_0/ You need more information?
