Spróbuj odczytać statyczny int BatteryManager.EXTRA_TEMPERATURE

Możesz uzyskać temperaturę procesora za pomocą tej funkcji: Pobierz temperaturę procesora z urządzenia z systemem android za pomocą polecenia sys/class/thermal/temp.

public float getCpuTemp() {
    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();
        float temp = Float.parseFloat(line) / 1000.0f;
        return temp;
    } catch (Exception e) {
        e.printStackTrace();
        return 0.0f;
    }
}

Spróbuj tego:

 private class mBatInfoReceiver extends BroadcastReceiver{ 

    int temp = 0;

    float get_temp(){
        return (float)(temp / 10);
    }

    @Override 
    public void onReceive(Context arg0, Intent intent) {

      temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE,0);

    }

  };

Następnie zdefiniuj w swojej zmiennej deklaracje:

private mBatInfoReceiver myBatInfoReceiver;

I in onCreate:

    @Override 
    public void onCreate(Bundle b) { 
        super.onCreate(b);  
        setContentView(R.layout.activity_main);

        // ...
        // Add this

        myBatInfoReceiver = new mBatInfoReceiver();                                     

        this.registerReceiver(this.myBatInfoReceiver,
                              new IntentFilter(Intent.ACTION_BATTERY_CHANGED));

     }

Późniejsze wywołanie np. w onclicklistener ()

float temp = myBatInfoReceiver.get_temp(); 

String message = "Current " + BatteryManager.EXTRA_TEMPERATURE + " = " +
                  temp +  Character.toString ((char) 176) + " C";
