Google has made great strides with Android, and a ton of developers have flocked to growing mobile platform. Bu not everything is rosy, though. One major concern among developers is that piracy levels are very high on the platform. Google in July announced plans to combat piracy with DRM methods. But there's another major problem that is arguably much more problematic for Android developers when it comes to getting paid for their apps, and it isn't getting nearly as much attention as we think it should," pingdom writes.
You can only pay for apps in 13 out of the 46 or so countries where Android phones are available. For those of you who like stats, 13 in 46 works out to less than 30%. Contrast this with Apple's App Store, which supports paid apps in 90 countries. This's a huge advantage iPhone developers currently have over Android developers.
