我必须从 android 的 webview 上传文件。现在，除了 android kitkat 之外，这一切正常。我经历了以下。
https://code.google.com/p/android/issues/detail?id=62220
android webview中的HTML文件输入（android 4.4，kitkat）
正如第二个问题（agomes answer）中所建议的那样，我尝试使用人行横道。我正在使用 eclipse，我按照说明设置了一个简单的 Crosswalk webview，但应用程序不断崩溃。f 有人知道在 Android 4.4.2 中从 webview 上传图像的更简单/更好的方法也会有所帮助。
我不能使用cordova，因为我不能在服务器端更改代码。
//Webview Activity
public class MainXWalkActivity extends XWalkActivity{
private XWalkView mXWalkView;
@Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.fragment_falcon_management);
super.onCreate(savedInstanceState);
//
}
@Override
protected void onXWalkReady() {
// TODO Auto-generated method stub
initViews();
mXWalkView.load("http://crosswalk-project.org/", null);
}
private void initViews(){
mXWalkView = (XWalkView) findViewById(R.id.xwalkWebView);
mXWalkView.setUIClient(new XWalkUIClient(mXWalkView));
mXWalkView.setResourceClient(new XWalkResourceClient(mXWalkView));
XWalkPreferences.setValue(XWalkPreferences.REMOTE_DEBUGGING, true);
}
}
XML文件是：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/bg_app"
android:orientation="vertical" >
<org.xwalk.core.XWalkView
android:id="@+id/xwalkWebView"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#000000"
/>
</LinearLayout>
