I am trying to extract thermal information in an android application programmatically but there is not enough documentation to do so.
The things which I want to extract are like this:
vbal_low - 37.9 C
gold-virt-max-step - 28.2 C
cpu3-silver-lowf - 27.8 C
msm-therm-adc - 26 C
mdm-dsp - usr - 30.1 C
gpu0-lowf - 27.5 C
wlan-lowf - 28.1 C
and there are like other 50 or so temperature values, how to do so?
public float thermalTemp(int i) {
Process process;
try {
process = Runtime.getRuntime().exec("cat sys/class/thermal/thermal_zone"+i+"/temp");
process.waitFor();
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line = reader.readLine();
if(line!=null) {
float temp = Float.parseFloat(line);
return temp / 1000.0f;
}else{
return 51.0f;
}
} catch (Exception e) {
e.printStackTrace();
return 0.0f;
}
}
public String thermalType(int i) {
Process process;
String line = null;
try {
process = Runtime.getRuntime().exec("cat sys/class/thermal/thermal_zone" + i + "/type");
process.waitFor();
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
line = reader.readLine();
} catch (Exception e) {
e.printStackTrace();
}
return line;
}
