I am trying to figure out how feasible Blackberry's rumored intent to have the Playbook tablet access the Android App store will be.

There have been several news/blog reports on this matter, but i haven't seen any feedback from the app developer community on this forum regarding what the experience will be like for Playbook users, whether apps would need to be altered by developers going forward to accommodate for the Playbook, what Google and Blackberry would have to do to ensure that the user experience is seamless.

From an app developer's perspective, I imagine this is a huge homerun, as it opens up sales opportunities to Blackberry customers. However, there are likely risks of alienating some users if the experience isn't the same as one would get on, say, a Galaxy Tab or the Motorola Xoom.

Here is an article on the topic: http://www.slashgear.com/blackberry-playbook-android-app-support-coming-in-2h-2011-tip-insiders-11132674/

What do app developers at large think about QNX facilitating this?

BlackBerry Playbook 上的 BlackBerry Tablet OS 2.0(基于 QNX)中的 Android App Player 运行良好。

我自己利用了“Android 开发者免费剧本”促销http://devblog.blackberry.com/2012/02/latest-blackberry-playbook-tablet-offer-for-android-developers/并移植了一个简单的 Android 应用程序到剧本。我很高兴地说我已经收到了剧本并且我很喜欢它。

就我而言,“移植”过程非常简单。我只需要更改应用程序的图标(Playbook 需要为 86x86),调整更大屏幕的布局(我的 Android 应用程序没有针对平板电脑进行优化),然后对应用程序进行数字签名并将其打包为 BlackBerry 的 .bar 格式。这一切都非常简单。

可以移植到 Playbook 的内容有一些限制,首先,Android 应用程序不能使用任何本机代码(没有 Android NDK):

Android 应用程序需要重新打包并提交到 BlackBerry App World,Playbook 用户不能只是去 Android Market 下载他们想要的任何东西。但是,除了 AppWorld 中提供的那些之外,还有其他方法可以运行 Android 应用程序,只需将设备置于开发模式即可,无需 root:

就用户体验而言,第一次在 Playbook 上运行 Android 应用程序时,Dalvik 虚拟机初始化需要很长时间,但随后应用程序运行速度很快,打开后续的 Android 应用程序也很快——显然是 Dalvik 进程留在记忆中。Playbook 没有“菜单”物理按钮,因此您可以通过从屏幕顶部向下滑动来访问应用程序的菜单。也没有“返回”按钮,因此他们在屏幕底部附近提供了一个虚拟按钮。

实际上,目前 PlayBook 甚至不支持为黑莓智能手机编写的 Java 应用程序。恕我直言,现在谈论 Android 支持还为时过早。
