How do you calculate the CPU temperature?
- Import these:
import java.io.BufferedReader;
import java.io.InputStreamReader;
Then use this:
@SimpleProperty(description = "Returns the CPU temperature of the device.")
public static float CpuTemperature () {
Process process;
try {
process = Runtime.getRuntime().exec("cat sys/class/thermal/thermal_zone0/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;
}
}
How do you find the Android version?
Import this:
import android.os.Build.VERSION;
Then use this:
@SimpleProperty(description = "Returns the Android version of the phone.")
public String AndroidVersion () {
if (android.os.Build.VERSION.SDK_INT == 9) {
return "2.3";
} else if (android.os.Build.VERSION.SDK_INT == 10) {
return "2.3.3";

return "4.4W";
} else if (android.os.Build.VERSION.SDK_INT == 21) {
return "5.0";
} else if (android.os.Build.VERSION.SDK_INT == 22) {
return "5.1";
} else if (android.os.Build.VERSION.SDK_INT == 23) {
return "6.0";
} else if (android.os.Build.VERSION.SDK_INT == 24) {
return "7.0";
} else if (android.os.Build.VERSION.SDK_INT == 25) {
return "7.1";
} else if (android.os.Build.VERSION.SDK_INT == 26) {
return "8.0";
} else if (android.os.Build.VERSION.SDK_INT == 27) {
return "8.1";
} else if (android.os.Build.VERSION.SDK_INT == 28) {
return "9";
} else if (android.os.Build.VERSION.SDK_INT == 29) {
return "10";
} else if (android.os.Build.VERSION.SDK_INT == 30) {
return "11";
} else if (android.os.Build.VERSION.SDK_INT == 31) {
return "12";
} else {
return "UNKNOWN";
