How to detect android cpu speed?

I would like to detect how fast is the device on which my Android application is running?

Is there any API to do it on Android? Or do I have to benchmark it by mysel

Try reading /proc/cpuinfo which contains cpu information:

   String[] args = {"/system/bin/cat", "/proc/cpuinfo"};
   ProcessBuilder pb = new ProcessBuilder(args);

   Process process = pb.start();
   InputStream in = process.getInputStream();
   //read the stream
