Question

在我的应用程序中，我周期性地用WebView调用fragment，以显示PowerBi数据一段时间。首次调用片段时，分析器显示该应用程序使用了大约+ 60MB的内存。而且每次调用一次又一次时，它将占用+ 30MB的内存。我认为应用程序不会覆盖网页数据，而是将其存储到缓存中。

mWebView = view.findViewById(R.id.webView);
                    mWebView.setWebViewClient(new WebViewClient());
                    mWebView.getSettings().setJavaScriptEnabled(true);
                    mWebView.getSettings().setDomStorageEnabled(true);
                    mWebView.setOverScrollMode(WebView.OVER_SCROLL_NEVER);
                    mWebView.loadUrl("https://mylink");

这是堆栈跟踪：

[ERROR:gles2_cmd_decoder.cc(2009)] [GroupMarkerNotSet(crbug.com/242999)!:7C501C92]GL ERROR :GL_INVALID_OPERATION : BackFramebuffer::Destroy: <- error from previous GL command

I/art: Wrote stack traces to '/data/anr/traces.txt'

好吧，我已经创建了CountDownTimer并设置了几行要在WebView的末尾执行的代码。我加了：

mWebView.clearCache(true);
mWebView.destroy();

仍然，当应用程序运行了一整夜后，它崩溃了。这是堆栈跟踪：

这是Crashlytics中相同崩溃的代码：

我不确定问题出在哪里以及如何解决。

Android应用程序停止运行，也许WebView使用了过多的内存
