Download PDFs to Android Web View

in my android application i need to upload pdf to server in webview . according to the question, I used the Google DOC view at boot time. but my problem doesn’t show the file several times in webview , while in another instance it shows up quite well. I can not understand the problem. but the code looks fine. my code segment is as follows.

WebViewLable.getSettings().setJavaScriptEnabled(true);    
    WebViewLable.getSettings().setLoadWithOverviewMode(true);
    WebViewLable.getSettings().setUseWideViewPort(true);  

    fullURL=GoogleDOCview+"https://livefarmer.com/labels/"+itemURL;
    WebViewLable.loadUrl(fullURL);

}

private class Callback extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(
            WebView view, String url) {
        return(false);
    }
}

and my webview is as follows.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/app_bg_black"
    android:orientation="vertical" >

    <include
        android:id="@+id/nav_bar"
        android:layout_width="fill_parent"
        layout="@layout/nav_bar" />


    <WebView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/webViewLable"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:windowSoftInputMode="adjustResize" />

</LinearLayout>

, , WebView , 0, URL.

        myWebView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                if (view.getContentHeight() == 0) setUrl();
            }
        });

setUrl() :

private void setUrl() {
     myWebView.loadUrl("http://docs.google.com/gview?embedded=true&url=" + pdfUrl);
}
