Question

我的代码设置在API 7然后我将其更改为API 15，以便我可以onGenericMotionListener

现在我将我的活动定义如下：

  newGame.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                vibe.vibrate(vibValue);

                   if (levelStage == 1 && levelId == 1)
                   {       
                       Intent myIntent = new Intent(v.getContext(), Level.class);
                       startActivity(myIntent);
                   }
                   else
                       displayAlertForNewGame(v.getContext());
            }
        });

每当我尝试启动此活动时，我都会收到错误java.lang.NoClassDefFoundError

使用此代码启动活动

Intent myIntent = new Intent(v.getContext(),myActivity.class);
                        startActivity(myIntent);

问题来自班级com.code.global.Level。这门课来自哪里？它是在jar中，你是否在构建路径中以正确的方式包含它？

使用Generic Motion侦听器时未找到类定义
