title: After Click Button do not open the new activity
body: <p>I have some problems to lunch a new activity after click in a button, I have review hundreds of times the code but I don't find the mistake which I think it is in the manifest. </p>
  
  <p>Could you help me?</p>

  <p>MainActivity code:</p>
  
  <pre><code>case R.id.bInputInventory:
                  //Go to Input screen
                  try{
                      Class ourClass = Class.forName("com.example.productioncontrolinventory.Inputinventory");
                      Intent ourIntent = new Intent(MainActivity.this, ourClass);
                      startActivity(ourIntent);
                   }catch(ClassNotFoundException g){
                          g.printStackTrace();
                          }
                  break;
