android how to change long to decimal and display the result

I am making an app. The app will calculate pmt function, its all working fine but the final result were not. The result could be displayed in int/long format but the request is to make it able to be displayed in currency format/decimal format that looks like currency.I am trying to display the results. However my implementation is bad and when the function called the app will crash.

editted:here is the code(just example):

   public class TableOutput extends Activity {
    TextView MyTextView ;
    String variable1;
    String todecimal;
    @Override
    protected void onCreate(Bundle bundle) {
        // TODO Auto-generated method stub
        super.onCreate(bundle);
        setContentView(R.layout.tableoutput);

        DecimalFormat formattedStuff = new DecimalFormat("#,###,###,###,##0");

        MyTextView = (TextView) findViewById(R.id.textview1);

        bundle = getIntent().getExtras();
        long CalculationResult = bundle.getLong("MyCalculationResultFromAnotherClass");

        variable1 = Long.toString(CalculationResult);

        todecimal = formattedStuff.format(variable1);

        MyTextView .setText(todecimal +" IDR");

    }       
}

the logcat:

Formater can't convert the string so use long or double.

public class TableOutput extends Activity {
TextView MyTextView ;
String variable1;
String todecimal;
@Override
protected void onCreate(Bundle bundle) {
    // TODO Auto-generated method stub
    super.onCreate(bundle);
    setContentView(R.layout.tableoutput);

    DecimalFormat formattedStuff = new DecimalFormat("#,###,###,###,##0");

    MyTextView = (TextView) findViewById(R.id.textview1);

    bundle = getIntent().getExtras();
    long CalculationResult = bundle.getLong("MyCalculationResultFromAnotherClass");

    variable1 = Long.toString(CalculationResult);

/*todecimal = formattedStuff.format(variable1);
 Formater can't convert the string so use long or double.
*/
todecimal = formattedStuff.format(CalculationResult);

    MyTextView .setText(todecimal +" IDR");

}       
}

Try below code

public class TableOutput extends Activity {
TextView MyTextView ;
String variable1;
String todecimal;
@Override
protected void onCreate(Bundle bundle) {
    // TODO Auto-generated method stub
    super.onCreate(bundle);
    setContentView(R.layout.tableoutput);

    DecimalFormat formattedStuff = new DecimalFormat("#,###,###,###,##0");

    MyTextView = (TextView) findViewById(R.id.textview1);

    bundle = getIntent().getExtras();
    long CalculationResult = bundle.getLong("MyCalculationResultFromAnotherClass");

    //variable1 = Long.toString(CalculationResult);

    todecimal = formattedStuff.format(CalculationResult);

    MyTextView .setText(todecimal +" IDR");

}
