How to read cpu frequency on android device [closed]
To have frequency on Android, just read these special files in /sys directory:
#cat "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq"#cat "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq"#cat "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq"You will have current, min and max Frequency allowed.
not MHz, but at least something. bogoMIPS value can be useful for you.
private String ReadCPUinfo() { ProcessBuilder cmd; String result=""; try{ String[] args = {"/system/bin/cat", "/proc/cpuinfo"}; cmd = new ProcessBuilder(args); Process process = cmd.start(); InputStream in = process.getInputStream(); byte[] re = new byte[1024]; while(in.read(re) != -1){ System.out.println(new String(re)); result = result + new String(re); } in.close(); } catch(IOException ex){ ex.printStackTrace(); } return result; }
