Users must remember that Android is still in its infancy. The first year's worth of Iphone Apps were not exactly that numerous or stellar. However, there is some truth to the statement that the lowest bar of Android apps may be a bit lower. This is due to two reasons:
1. The fact that the initial barrier to entry to create an android app might be a bit easier (due to all of the released source and the free SDK)
2. The fact that it is more difficult to support such a varying range of hardware and software
Time will help all of this as developers pool their knowledge and experiences with some of the issues that are continually being encountered and tackled as new hardware and updates hit the market.
Another issue is the almighty dollar... Monetizing, AKA: getting paid what we deserve for our work, is also still difficult and a great unknown due to the risk of not knowing the size of the market and the long term future. It will take developers a while to flock to Android and spend all of their development time writing android code until they know that income is possible.
What we have quickly learned in our development process is that writing a GREAT app for Android is proving to be more difficult than most realize if one is trying to support ALL of the android devices across the board and the developers are dedicated to making it a high quality, well behaved, bug-free app. As more of the devices are upgraded to 2.0+ there will be a huge increase in the quality of the apps as well.
Case in point: We spent an entire morning today chasing down some issues with playing soundtracks and sound effects in 1.5. There are VERY small limits on the size of the sound pool in 1.5 and thus the way the soundtracks were coded and instantiated in the game had to be altered. The extra coding and sound editing would not have been an issue had the situation been better documented or not existed!
Luckily, issues like this will not exist in the future as the general android population progresses on to the bigger and better versions, documentation, exchange of information, etc.!
Essentially what will probably happen is that the phones that do not have dedicated graphics chips will not get the newest versions of android and thus be left behind. This is actually a good thing, because apple will at some point have to stop supporting their legacy devices to keep up - which will be a large chunk of their existing population, whereas android phones will be more of a gradual phasing out similar to the way computers (or their owners rather) are self selecting for obsolescence or new OS upgrades.
CONCLUSION: There are android app developers out there that are working very hard and are very close to releasing some HIGH quality impressive games. Just be patient. Our first app release will be early next week! It will have polished graphics, custom sounds, have all of the i's dotted and t's crossed, and will be well supported! It is all very exciting.
