我需要加载从资产的图像，以避免升级Froyo 2.2.2错误调整POT图像在某些特殊情况下。的方式，以避免它是从资产目录加载的图像文件。

i need to load a image from assets to avoid a froyo 2.2.2 bug resizing POT images in some particular cases. The way to avoid it is loading the image files from assets dir.

我想用这样的：

        String imagePath = "radiocd5.png";
    AssetManager mngr = context.getAssets();
    // Create an input stream to read from the asset folder
    InputStream is=null;
    try {
        is = mngr.open(imagePath);
    } catch (IOException e1) {  e1.printStackTrace();}

    //Get the texture from the Android resource directory
    //InputStream is = context.getResources().openRawResource(R.drawable.radiocd5);
    Bitmap bitmap = null;
    try {
        //BitmapFactory is an Android graphics utility for images
        bitmap = BitmapFactory.decodeStream(is);

    } finally {
        //Always clear and close
        try {
            is.close();
            is = null;
        } catch (IOException e) {
        }
    }

但我得到的NullPointerException就行了 is.close（）;

我捕获FileNotFoundException异常：radiocd5.png，但该文件是对我的资产目录：•

i capture a FileNotFoundException: radiocd5.png, but that file is on my assets directory :S

我在做什么不好？该文件称为 radiocd5.png ，它是在资产目录

What am i doing bad? The file is called radiocd5.png and it is on the assets directory
