Android项目中WebView的内存泄漏

我正在将一个java项目应用到Android项目中。java项目使用来自Android项目的Activity对象的引用当我调用java项目上的函数时，我发送Activity引用。到目前为止还可以，但有时会出现错误。这是内存泄漏：

我也搜索过了，发现这不是开发者的错，但我不知道这两者是否有联系。堆栈跟踪中没有太多细节，但在上面的一个跟踪中，我的代码肯定是这样的

我不知道；i don’我不知道现在要尝试什么，我应该不从主线程显示webview吗

mActivity.runOnUiThread(new Runnable() {
                public void run() {
                    mWebView = MyWebViewFactory.create(mActivity, "");
                    dialog = MyWebViewFactory.showWebView(mActivity, mWebView);
                }
            });

及

谢谢

mActivity.runOnUiThread(new Runnable() {
                public void run() {
                    mWebView = MyWebViewFactory.create(mActivity, "");
                    dialog = MyWebViewFactory.showWebView(mActivity, mWebView);
                }
            });

public static Dialog showWebView(final Activity context, final WebView webView) {
        Dialog callAlert = new Dialog(context,
                android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);

        webView.getSettings().setBuiltInZoomControls(true);
        webView.getSettings().setSupportZoom(true);
        webView.getSettings().setLoadsImagesAutomatically(true);

        webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        callAlert.requestWindowFeature(Window.FEATURE_NO_TITLE);
        Window window = callAlert.getWindow();
        window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        callAlert.setCanceledOnTouchOutside(true);
        callAlert.setContentView(webView);
        callAlert.getWindow().setBackgroundDrawable(
                new ColorDrawable(android.graphics.Color.TRANSPARENT));
        callAlert.getWindow().setLayout(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT);
        callAlert.getWindow().setFormat(PixelFormat.TRANSLUCENT);
        callAlert.setCancelable(true);
        return callAlert;
    }
