Question

我的小部件有问题，我使用的是note 8（带有nova启动器），并且每次系统要杀死我的小部件时，因为它说我的程序多次停止运行或无法回答，并且是电池浪费^ _ ^

窗口小部件只是一个简单的视图，它显示了我从另一个页面加载的文本（最后一个代码），并且应该显示给我前三行，当我单击窗口小部件时，它显示了另外三行（并且如果再次单击，它将再次下载页面并重新启动周期），这就是它的作用，但是，如果我重新启动电话，则小部件将停止工作，并且我将无法对其进行任何操作（如果我删除了小部件并再次添加到屏幕的首页仍被阻止），几个小时后又重新开始
几乎处于“ hello world”的水平，但是我不明白什么是行不通的

有任何提示吗？
