Re: [android-developers] INSTALL_FAILED_DUPLICATE_PERMISSION
Thanks for sharing the link. I wasn't aware of this bug report. Yes both apps are mine, but even though they have the signature, some user complain about this error. Maybe they installed the apps form different sources, i.e. Amazon and Google Play. cheers Marten Am Freitag, 20.

Re: [android-developers] INSTALL_FAILED_DUPLICATE_PERMISSION
I'm seeing this with android:protectionLevel="normal" too. Since Android doesn't grant permissions that had not been declared yet, this forces the user to install apps declaring / using the permission in a certain order. This is a pain for the user, so the developer of one app that works with mine (and needs a permission declared there) added an identical permission declaration stanza in his app too. A clever hack, on Android prior to 5.0, it lets the user install mine and his apps in either order. Since Android 5.0, only one app can be installed at a time -- trying to install the other one fails with Play error code 505. I don't work for Google, so can only post a link to the bug tracker -- https://code.google.com/p/android/issues/detail?id=79375 -- and maybe recommend trying "signature" protection level, since both apps are yours and (as I understand) you hadn't released the new one yet, so you can still make that change. -- K On Friday, February 20, 2015 at 11:33:25 AM UTC+3, marten wrote: > > Hi Marina, > > we're using android:protectionLevel="dangerous" because that's what we > think is suitable for personal data like tasks.

Re: [android-developers] INSTALL_FAILED_DUPLICATE_PERMISSION
Hi Marina, we're using android:protectionLevel="dangerous" because that's what we think is suitable for personal data like tasks. Also, it's what the CalendarProvider uses for the permissions to read and write calendars. At present the major issue is that some users get this error even though they install the properly signed version from Google Play. The root of all this is that there is no way to grant a permission that hasn't been granted at installation time. And Google is making it worse instead of fixing it. At present the only solution seems to be to use no permissions at all and that's certainly not what this is intended for. If there is someone from Google in this Forum: How is this intended to work? thanks Marten Am Donnerstag, 19.

Re: [android-developers] INSTALL_FAILED_DUPLICATE_PERMISSION
Hi! I'm not sure how to help, because've only met this problem when there are several users set on a device. If I install my app directly from Eclipse with my debug certificates, then uninstall the app and try to install a production copy, made with the release certificate, I've got the same error message INSTALL_FAILED_DUPLICATE_PERMISSION. Until I uninstall the app in every user by hand, I can't install the new one. At least in your case the error message makes sense :) When I was trying to understand that error message, I've read that it affected permissions with android:protectionLevel declared as "signature". Are you using that? Can you change it to "normal" without affecting your business model? Marina On Wed, Feb 18, 2015 at 11:58 AM, Marten Gajda wrote: > Hi all, > > we've some problems with Android 5.

[android-developers] INSTALL_FAILED_DUPLICATE_PERMISSION
Hi all, we've some problems with Android 5. There seems to be a new policy that requires two apps that define the same permissions to be signed by the same key. Otherwise you can't install the app getting the error INSTALL_FAILED_DUPLICATE_PERMISSION. This is very annoying and I'd like to know that the suggested solution/workaround to this is. We have an Open Source task app that provides access to the tasks via a ContentProvider. The concept pretty much equals the CalendarProvider. We also have a (not yet Open Source) sync app that can sync to this task app (or its ContentProvider). The problem is that (in contrast to the CalendarProvider) our users usually install the sync app first. That means the permissions of the task app are not known when the sync app is installed. So they are not granted automatically when the task app is installed afterwards. Until Android 5 the solution was to define the same permissions in the sync app. But that doesn't work any more in some cases. If the user compiles the task app himself he can not use our sync app at the same time, because they are not signed by the same key. How can we achieve that we protect access to the task ContentProvider by permissions still allowing them to use a self compiled version? Even if both apps are signed by the same key it doesn't seem to work in some cases (does Android 5 also require both apps to be from the same source?) A similar issue exists when another developer tries to build a sync app that can sync to our task app. He can not add the same permissions, because he can't use the same signing key. But if he can't add the same permission definition his app won't get the permission if it's installed before the task app is installed. What's the solution of this mess? thanks Marten -- Marten Gajda Schandauer Straße 34 01309 Dresden Germany tel: +49 177 4427167 email: mar...@dmfs.org twitter: twitter.com/dmfs_org VAT Reg.
