Well, I have an Asus Eeee Transformer TF101 here running 3.2.1 (api 13). Audio appears to work. Building today's tip without re-running introjucer on the JuceDemo project I get Latency results of:
19699 Samples (446.7 mS)
Reports Input 8192, output 16384
So correct is -4877 (-110.59 mS)
I then rebuilt the Introjucer the required -LD libs looks like it has changed to me (__android_log... perhaps?). Set the min SDK to 10, and saved. This did pass the JUCE_ANDROID_API define on the command line (10).
That did cause an "Android OpenSL" device to appear. It appears to record and play, but Latency Test always reports "Couldn't detect the test signal". The sound 'sounds' the same. Interestingly, switching to Android Audio doesn't make a difference. Still no latency test results, though record and playback work.
I don't have time to dig any deeper today, but let me know if there is something else you would like me to test.
