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 of the device?
Import this:
import android.os.Build.VERSION

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";
} else if (android.os.Build.VERSION.SDK_INT == 11) {

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";
}

How to enable and disable Bluetooth?
Import this:
import android.bluetooth.BluetoothAdapter;
Add this:
@UsesPermissions(permissionNames = "android.permission.READ_PRIVILEGED_PHONE_STATE, " + "android.permission.BLUETOOTH_ADMIN")
