With respect, this is not the only example of fragmentation in the
Android ecosystem.

ICS can't loop audio seamlessly with more than one core, when using
MediaPlayer->setLooping(true). This is a major bug that is causing
problems for my applications. I have a sample project below
demonstrating the issue.
I have included a link to a very simple eclipse project that you can
use to test for the setLooping bug. This bug doesn’t seamlessly loop
an audio file. It plays a simple sine wave that can be used to easily
detect if your device is displaying the bug. I have also provided the
direct like to the apk file as well.
I feel this bug is an important bug to get fixed. Although this is a
simple example, it has real world problems including:
*Looped music playback
*Sound machine type applications
*Game sample loops
I feel this bug hurts the Android platform and encourages the
‘fragmentation’ fault argument. Some devices/firmware don’t present
the bug while others do. For example, almost every recent Motorola
device has the bug, but most HTC devices don’t. The Xoom shipped
without the bug, but a firmware update introduced the bug (I don’t
know which version introduced it).
I have an application, SleepyTime, which used to be available on all
devices but now isn’t available on many devices on the Android Market
because the bug is present on those devices. This creates a bad user
experience for the user because:
*A user on phone A can get the app, but a user on phone B may not be
able to.
*A user with phone X paid for the app, then upgrades to phone Z, which
can’t get the app because this device has the bug, and now doesn’t
understand why they can’t download the application they paid for.
To anyone experiencing this bug, please run this application on any
device you have access to and report the Android version, kernel,
device name, and weather the bug is present. We need to give the
engineers as much information as possible if we want this to get
resolved. Please get as many people as possible to start this bug to
give it more visibility.
