title: How do I convert from binary to decimal in java (using android studio)
body: <p>I am making an android app and one of the components of the app is designed to take a number in binary and convert it to decimal. Every time I run it, it crashes.</p>
  
  <pre><code>public void Button0Clicked(View v)
  {
          TextView myText = (TextView)findViewById(R.id.textView);
          if (firstType == true)
      {
          myText.setText("");
          firstType = false;
      }
      myText.setText(myText.getText() + "0");
  
  }
  public void Button1Clicked(View v)
  {
          TextView myText = (TextView)findViewById(R.id.textView);
          if (firstType == true)
          {
              myText.setText("");
              firstType = false;
          }
          myText.setText(myText.getText() + "1");
  }
  public void Conversion(View view)
  {
          TextView myText = (TextView)findViewById(R.id.textView);
          int decimalValue = Integer.parseInt(myText.getText().toString(),2);
          TextView result = (TextView)findViewById(R.id.textView2);
          result.setText(decimalValue);
  
  }
  </code></pre>
  
  <p>I've narrowed the problem down to some problem with the Integer.parseint() function, is my implementation wrong?</p>
