Java/Android: Passing Intent Extras, then use it on another method

Hello again everyone,
This time I have a problem with Intent & Extras.

here's my first activity

Intent i1 = new Intent(RoomSetting.this, App.class);
i1.putExtra("subposition1", "right");
final int result=1;
startActivityForResult(i1, result);

and in the 2nd activity I try to get "subposition1" value

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mAccVals = new Number3d(); 
    Bundle extras = getIntent().getExtras();
    String SubPos = extras.getString("subposition1");
}

My question is, how can I use SubPos on another method?

Sorry for noobish question. Thanks in advance

There are 2 ways of doing it easyly:

First way: Use a global variable for the class:

   String SubPos;
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mAccVals = new Number3d(); 
    Bundle extras = getIntent().getExtras();
    SubPos = extras.getString("subposition1"); //note that I've deleted the 'String'
}

2n way: Pass to the method the variable:

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mAccVals = new Number3d(); 
    Bundle extras = getIntent().getExtras();
    String SubPos = extras.getString("subposition1");
    otherMethod(SubPos);
}

public void otherMethod(String s) {
    //do stuff.
}

I considered that maybe you want this variable in another class, then you could do it adding this function (having the String SubPos as global in the class):

   String SubPos;
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mAccVals = new Number3d(); 
    Bundle extras = getIntent().getExtras();
    SubPos = extras.getString("subposition1"); //note that I've deleted the 'String'
   }
    public String getSubPos() {
        return SubPos;
    }

This way you can call the instanceOfTheClass.getSubPos() in any other class that has the instance.

Just call this on your "other method".

String subposition = getIntent().getStringExtra("subposition1");

Replace 

Bundle extras = getIntent().getExtras();
String SubPos = extras.getString("subposition1");

with

String SubPos = getIntent().getStringExtra("subposition1");

declare SubPos before onCreate as:

public String SubPos=null; // or you can also declare it as static as your need
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mAccVals = new Number3d(); 
    Bundle extras = getIntent().getExtras();
    SubPos = extras.getString("subposition1");
}


   public void testmethod()
   {
      String str=SubPos; //get SubPos value  
    }

String SubPos;
// declare SubPos String as class variable and you can access anywhere in class<<<
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mAccVals = new Number3d(); 
    Bundle extras = getIntent().getExtras();
    SubPos = extras.getString("subposition1");
}

public void anotherMethod(){
//here you can access it...
}
