 Hi, all
I checked the logcat, I find it cannot find the jni_Onload,
Thanks for your information, I find I forget the function jni_Onload method,
it is a new requirement after jni)1.2
Now my hello world working.
Thanks
With best wishes
Jerry

1. WebView with theme doesn't show focused text field values

I have encountered a problem with focused text fields in a WebView not
showing entered text values.  As long as a WebView text field has
focus it will not show text or even the blinking cursor.  You can
select and highlight the text or unfocus the field to see it, but when
it gains focus it will not show the text... as if the foreground color
of the text is white.

The simplest code to demonstrate this is below.  With the setTheme
using a Light background, try typing values into the Email text field
to notice that the text is not visible when the field is focused.

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;

public class AndTest extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setTheme(android.R.style.Theme_Light_NoTitleBar); // <--
causes focused text fields not to show entered text

        WebView webContent = new WebView(this);
        webContent.loadUrl("http://m.myspace.com");

        setContentView(webContent);
    }
}


If the setTheme is set for a Light theme, the text in focused fields
cannot be seen.  I also have this happening in my program without the
theme if there are multiple Views within Views that have background
colors, but the above code replicates the problem.

Any suggestions or help is greatly appreciated.
