Need to read android sensors really fast

Question

Issue:-

1. I am developing a application which needs a new acceleration datum every 5 millisecond.

My Approach:-

Answer 1

Regarding the speed of the Android SensorManager, I would be more inclined to suspect the speed of the Android file I/O that is generating your log. You might try a benchmark of your sensor read code without writing to the log. Something like logging the current time in milliseconds, then doing 1,000,000 sensor reads, then logging the current time again. You might still have to use the C version to get the data, but at least you'll know definitively where the bottleneck lies.
