Question

仅在单击按钮时才尝试通过启动DetectorActivity（执行检测的主要活动）来调整应用程序。因此，在源代码中，我添加了一个类“ Main Activity”，将其设置为清单中的启动活动，并在xml中添加了一个按钮，单击该按钮应将意图发送给DetectorActivity并启动它。代码差不多是这样的：

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void on(View v){
        Intent i = new Intent(this,DetectorActivity.class);
        startActivity(i);
    }

但是，该活动从未启动，这非常令人困惑。这是模拟器的日志：
