import android.os.Message;

public class JniTestHelper {
    private static Handler mHandler;
    public static void init(Handler handler)
    {

    }

    public static native void setPackageName(String packageName);

    public static native void exitApp();
    //c++    java   ，       
    private static void showTipDialog(final String title, final String text)  
    {
        Message msg = mHandler.obtainMessage();  
        msg.what = DialogBox.SHOW_DIALOG;  
        DialogMessage dm = new DialogMessage(title, text);  
        msg.obj = dm;  
        msg.sendToTarget();  
    }

}

package com.DialogBox.org;

public class DialogMessage {
    public String title;
    public String msg;

    public DialogMessage(String title, String msg) {
        super();
        this.title = title;

    }

        // GuideLayer should create stencil buffer
        glSurfaceView.setEGLConfigChooser(5, 6, 5, 0, 16, 8);

        return glSurfaceView;
    }    

    //        
    private Handler mHandler = new Handler()
    {
        @Override
        public void handleMessage(Message msg) {
            switch(msg.what)
            {

                DialogMessage dm = (DialogMessage)msg.obj;
                new AlertDialog.Builder(DialogBox.this)
                .setTitle(dm.getTitle())
                .setMessage(dm.getMsg()).setNegativeButton("cancle", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                })
                .setPositiveButton("Ok", 
                        new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                        JniTestHelper.exitApp();
                    }
                })
                .create().show();
                break;
            }
        }
    };

3、備考:Dialog_CLASS_NAMEは実際の状況に基づいて定義するmkのLOCAL_SRC_FILESはDialogを追加する.cppパス.
