You can re-enable auto-updates for the ownCloud client
The ownCloud Android app will stick in the future to the tagging scheme oc-android-X.Y.Z
, it was just a mistake that 1.7.1 didn't follow the scheme and we will take care that it doesn't happen again. Sorry for the inconvenience but you can safely re-enable the auto update for com.owncloud.android.txt.
For reference, here we discussed the tagging scheme and agreed to stick to the scheme mentioned above: https://github.com/owncloud/android/issues/1063
