An Android Developer's Top 10 Gripes
gkunene writes in with the plaint of a veteran mobile application developer who vents his frustration with a list of 10 things he loves to hate about Android. "1. Open Source. Leave it to Google to place all the code for their handset platform in the hands of the masses. Not only does this mean anyone can download and roll a new version of their phone firmware, but it also means absolutely any maker can roll its own Android device. ... After all's said and done, I really must admit that Android, despite its relatively few flaws, is one of my favorite platforms to work with. Quite honestly, if my complaint about how the word 'Intent' makes for awkward grammatical constructions ranks in the top 10, I'd say the Android platform is doing pretty well for itself."
Apple? The test was done by Motorola!
Generally Android's java is very optimized and is terrific and surprisingly fast
I have no idea where you get this impression. Android's dalvik engine is widely known to be roughly 20x slower than most other non-JIT'd java VMs. Its slow by any measure. And worse, most CPU intensive tasks which are commonly required for many mobile applications fall into a category where performance is especially poor for the current Dalvik implementation.
The good news is that Android's Dalvik will soon have its initial JIT offering which will speed up applications, on average, roughly 100%-150%. Once readily available, Dalvik will be 10x-500x slower than native code; depending on the nature of the code.
