android 4.4.2中的webview冻结

Question

null

webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setDomStorageEnabled(true);
    webView.getSettings().setPluginState(PluginState.ON);
    webView.getSettings().setRenderPriority(RenderPriority.HIGH);
    webView.getSettings().setGeolocationEnabled(true);
    webView.getSettings().setPluginState(WebSettings.PluginState.ON);
    webView.getSettings().setAllowFileAccess(true);

我设置了webclient

webView.setWebChromeClient(new WebChromeClient() {            

@override公共布尔onShowFileChooser（WebView WebView,ValueCallback filePathCallback,FileChooserParams FileChooserParams）{返回True；}@override public void onGeolocationPermissionsShowPrompt（String origin,Geolocationpermissions.callback callback）{callback.invoke（origin,true,false）；}//openFileChooser for Android 3.0+public void openFileChooser（ValueCallback uploadMsg,String acceptType）{}//openFileChooser for Android<3.0 public void openFileChooser（ValueCallback uploadMsg,String acceptType）{}//openFileChooser for其他Android版本public void openFileChooser（ValueCallback uploadMsg,String acceptType）{openFileChooser（uploadMsg,acceptType）；}公共布尔OnConSeleSessage（ConSeleSessage cm）{OnConSeleSessage（cm.message（）,cm.lineNumber（）,cm.sourceID（））；返回true；}public void onconeLoneSessage（String message,int lineNumber,String sourceID）{}}）；//End setWebChromeClient

    webView.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return true;
        }
        @Override

        public void onPageFinished(WebView view, final String url) {

            super.onPageFinished(view, url);
            CookieSyncManager.getInstance().sync();
            Log.i("finished", url);
        }
    });

这是我的xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/drawer_layout"

Answer 1

使用3.0.0及以上版本的Gradle和compileSdkVersion 26以上版本会导致此问题...

我的解不是精确解，但它解决了问题...将app gradle切换到

classpath 'com.android.tools.build:gradle:2.3.0'

将模块级切换到

compileSdkVersion 25
buildToolsVersion '25.0.2'
