Preview: Xamarin Profiler 0.17

Xamarin Profiler preview 0.17 is now available for download! There have been a number of fixes since our previous preview, which have been noted below.

Please note that the Mac app bundle has been renamed (from XamarinProfiler.Mac.app to “Xamarin Profiler.app”), so the old version needs to be removed before installing this new update, so that Xamarin Studio prompts the user for the new location.

iOS Hotfix for iOS 9 Preview (Xcode 6)

We are releasing an updated set of builds to the Stable channel in order to address the issues noted in our iOS9/El Capitan Technical Preview blog post. As noted in that post, we feel we’ve completed sufficient testing on the Xamarin.iOS SDK that resolves the issues affecting both 32 and 64 bit apps running on iOS 9. With this new Xamarin.iOS release, you should be able to rebuild and re-submit your apps using Xcode 6 and have them run against iOS 9 previews, ready to prepare them for the fall release of iOS 9. Head over to our developer page to read up on prepping your app for iOS 9.

We will also be posting previews of the Xamarin.iOS SDK that supports Xcode 7 and the iOS 9 APIs soon. Those builds will be distributed via a preview site, and we will have a new blog post up when they are available.


Known Issues 

  • [Xamarin.VS] – Debugging on iOS 9 devices from Visual Studio is not yet supported.

Preview: Android M Support

We are releasing our first preview with support for Google’s Android M SDK. It also includes bindings for API 22/Android 5.1. Be sure to visit the Android M page and read about all the new features M support provides. If you are looking to get started right away, make sure to check out the new Android M samples and join in on the forum discussions.

There is no target stable date for M support at this time, as we have to wait until Google finalizes and publishes their support before we can release ours. That being said, we may do additional M preview releases between now and the final Google release, so be sure to check back and see if newer versions become available in the coming months.

As with all our preview releases, this is not a product we officially support. If you encounter any issues, we recommend filing a bug in Bugzilla. You can also jump into the discussions on the forum thread posted below.


Known Issues 

  • 31002 – [Xamarin.Studio / Xamarin.VS] – Users will have to manually make sure their minimum SDK version is set to v5.1 (22) or lower, instead of v5.2 (23), in order to deploy to M devices and emulators.

Alpha Release: Cycle 5 – Service Release 2

We are releasing a preview of our next upcoming stable release, dubbed Cycle 5 – Service Release 2, to the Alpha channel. These builds contain a number of additional fixes on top of our current stable products, and we’re looking to get them into the Stable channel later this month if all goes well.

As this is an Alpha preview, there are still some known issues to be aware of. These are regressions against the previous stable release of Cycle 5 – Service Release 1. We’re looking to have these fixed in an upcoming preview, but felt they were not severe enough to hold back an Alpha containing lots of fixes people may be waiting on.


Known Issues 

  • [Xamarin.VS] – Running a WatchKit app a second time causes an error.
  • [Xamarin.VS] – Deploying an Android application a second time on other emulators or devices fails and causes an error.
  • [Xamarin.Android] – Error when building with Supportv7/Pallete sample.

iOS 9 / El Capitan Preview Technical Bulletin

Yesterday Apple released the first previews of both iOS 9 and OS X El Capitan. We are working full-speed to add support for both iOS 9 and El Capitan right now, and we’ll keep you posted as things progress.

For iOS 9, we are investigating an issue that is causing a number of Xamarin apps to crash on startup. As we’re digging into this, the issue seems to be specific to apps that include 32-bit support.

Apple made some dramatic changes to OS X by making /usr/bin read-only, even with root access, so we’re working on making support for Xamarin Studio and the Xamarin Installer available as soon as possible to get up and running on OS X El Capitan.

As always, these are preview builds and we recommend staying with the stable releases of Xamarin and OS X and iOS until we make full support available for these previews available via this release blog and their preview sites.

Update: We have identified two issues that will affect both 32-bit and 64-bit apps on iOS 9. This has been released as a hotfix which you can find more detail on our hotfix blog post.

Android Hotfixes for Android M Preview

We have pushed a new Xamarin.Android SDK release and accompanying IDEs tools to the Stable channel to provide a few additional hotfixes that were needed based on the new SDKs provided at Google I/O.


Issues Addressed

  • 30555 – New “preview channel” build/sdk tool paths can now be processed
  • 30562 – Aapt path has changed in the latest build tools release
  • 30566 – Fixed an issue with java.lang.String throwing “java.lang.UnsupportedOperationException: Use StringFactory instead.” for most common constructors.
  • 30653 – Deployment failed because of an internal error: File name has not been set is now fixed.


 

Products Released To Stable

Stable Release: Cycle 5 – Service Release 1

After extensive internal and public Beta testing, we are ready to promote our current Beta channel builds to the Stable channel for our first Service Release. Internally we refer to this as Cycle 5 – Service Release 1, as the previous Stable release was a major platform upgrade, which we called Cycle 5.

PLEASE NOTE – These builds also include an important hotfix to support the latest version of SDK tools (24.3) released by Google last week at I/O, which we also mentioned in our forum thread last week.

If you happen to encounter any issues or are seeing errant behavior, please be sure to post to the related product threads on our Forums.


Products Released to Stable

Beta Release: Cycle 5 – Service Release 1

We have been hard at work on our first Service Release to address known and newly found issues with our most recent Stable products (internally referred to as Cycle 5 – Service Release 1).

We plan on doing some more internal testing of these builds, but would love for as many people as possible to grab the Beta builds and help us give them a run through.

Make sure to check out the release notes below before updating to get an idea of what has changed. Previously released builds are also available for installation if the beta builds do not meet your current needs (see guide here for how to do that). These older builds are noted within the respective product forum threads linked below.

If you happen to still be encountering any issues we believed to be fixed, are seeing new and errant behavior, or are otherwise having problems with products from this release, please be sure to post to the related product threads on our Forums. Our Support team uses these release threads, and will be communicating through them to help triage issues and supply in progress builds not yet in preview channels that may contain additional fixes.
