I work almost every day on android with NDK and Qt. Tools still poor and 
there is a lot of issues. I found one critical last week in the ndk : an 
error with a python dll causing gdb launch failure, so sometimes you 
just haven't debugger...

Developing games on such devices can be a real pain, apk can't exceed 
50Mo and updating files with the obb package must be done manually.

We never got those kind of difficulties with iOS even at the beginning.

PS : I just buy a Nexus 5 to replace my old Motorola defy, and there is 
absolutely no pauses everything is perfectly smooth. I had some doubts 
if it was possible before buying it cause of Java,... No I just think 
all constructors doesn't delivers good drivers and put completely buggy 
additional components making the bad reputation of Android.
On my defy I always got bad touch events,... It was a real pain to send 
an SMS :-{
