我的应用程序包含带有全屏webview的片段。当用户单击webview中的链接时，将使用具有相同url的新webview打开新的片段。在打开新的fragment之前，我关闭软键盘以防万一。我很快打开新页面。所有操作都在主线程上执行。
对于crashlytics，问题仅适用于android 10(所有pixel系列设备和其他配备10的设备)。
在android 10之前的设备上，一切正常。我可以打开很多片段。但是在android 10设备上，这种情况会导致致命异常(在2-3次快速尝试随机打开新页面之后)：
e/androidruntime: fatal exception: pool-1-thread-1

我试图使用android系统webview的所有可用版本(稳定版，测试版，开发者，金丝雀)，但无济于事。
有人可以帮助我吗？
更新：
如果我注释隐藏软键盘的代码，则一切正常。

关于twitter这一块，自发这篇博文之后有很多人问我，有的验证成功了不跳转，或者其它原因什么的，我看了一下，这篇博文里面有写呀，下面以红色粗体文字注明一下
刚进公司，叫我先学习twitter和facebook，就类似于国内的微博，或者分享功能，点击某个按钮，出来一个提示框，可以分享到某些地方，这里实现的就是分享到twitter，当然得要使用代理，因为这是给老外做的，所以得符合他们的习惯
先说一下实现的功能吧，首先运行的时候，会检查是否登陆twitter（通过sharedpreference文件保存登陆状态），如果没有登陆的话会跳转到twitter的登陆认证页面，提示用户输入用户名和密码，这些就是oauth认证的步骤，不懂的看这儿 www blogs /and_he/archive/2011/05/22/2053477.html
做过新浪微博的都应该知道，首先要申请成为开发者，创建自己的应用，然后会给你一些比如consumer key和consumer secret之类的东西，这些东西要先记下来，代码里面要用到的，其余的不啰嗦了，只是要注意一点，创建twitter应用的时候造成不能忘了填那个callback url，我当初就没填，结果整了几天都整不出来结果，也算是我的一点经验吧，下面贴代码，以便于以后查阅
首先我们要用到twitter封闭好的一些包，这里用到两个twitter4j-core-android和twitter4j-media-support-android，百度一下就出来了
