Google has opened up the Android Market to those devices that did not come pre-installed with the app store. A minor update was all that was needed so users of the HP TouchPad, the Barnes & Noble Nook, or the Kindle Fire can now have access to the Android Market. All that they have to do is download and install Android Market on their device. The Android Market website has loads of third party developed applications that once a user can download and use.
However, Google does not permit other online application stores to also be used on the device that is playing host to the Android Market. What this means is that if you have installed an app on your device from any other source, Android Market will be good enough to not only recognize that, but will also offer to update it if a more recent version is available. Here problems start to crop up, since it fails to update properly.
So until Google ensures its Android Market can peacefully co-exist with other app stores, we’re waiting anxiously for another fix.
