我的应用程序在到达线路时崩溃：

HttpEntity entity  = response.getEntity();

我不知道为什么，所以我尝试在调试模式下运行，但 Android Studio 一直告诉我：

警告：调试信息可能不可用。请关闭其他使用 ADB 的应用程序：Monitor、DDMS、Eclipse

而且我没有打开任何其他东西，实际上我只是重置了PC。

这是我的整个代码：

    @Override

        int numint = 0;
        String clientName = "";
        String email = "";
        double amount = 0;

        try {

        String text = numint + " "+ clientName + " " + email + " " + amount;

        display.setText(text);

    }

    public void initComponents() {
        display = (TextView) findViewById(R.id.textView);
    }
}
