NullPointerException while inflating WebCachedImageView

Hello there

I am currently working on an app and I am using this framework to get Images from the web. Unfortunately this framework throws an exception while inflating the WebCachedImageView. It is caused by a NullPointerException while getting the External Cache dir. According to the Android Context API the Method getExternalCacheDir(), which you are using and probably is returning null, returns null in case there is no external storage is mounted. To ensure that this is the problem, I’ve tested the application on a Device using an SD card as external storage and one without. Both are throwing the same following exception:

The code in the layout file:

<WebCachedImageView
    android:id="@+id/website_images"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_marginBottom="5dp"
    android:layout_marginRight="15dp"
    android:layout_marginTop="5dp"/>

Error initializing

Im try you library. Im use Emulator, API level 17, add WebCachedImageView to ListView throw ListViewAdapter

public View getView(int pos, View child, ViewGroup parent) {
        Holder mHolder;
        LayoutInflater layoutInflater;
        if (child == null) {
            layoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            child = layoutInflater.inflate(R.layout.sent_listview_item, null);
            mHolder = new Holder();
            mHolder.txt_fileName    = (TextView) child.findViewById(R.id.txt_sentLV_fileName);
            mHolder.img_preview     = (WebCachedImageView) child.findViewById(R.id.wciv);
            child.setTag(mHolder);
        } else {
            mHolder = (Holder) child.getTag();
        }
        mHolder.txt_fileName.setText(fileName.get(pos));
        return child;
    }

    public class Holder {
        WebCachedImageView img_preview;
        TextView txt_fileName;
    }

How to cacheImage when imageurl in JSON?

Direct image url is ok, I can cache it easily using this library. But my image url is listed in json, I can display it normally. But I happen to have problem to cache the image this way. Please advice.

Q: Use caching image from Cache in another ImageView

Hi!
Tell me plase, Is there a way Use caching image from Cache in another WebCachedImageView, because caching encoded filenames and I can not directly access the downloaded file, since I do not know his new filename, that would show this picture to a another ImageView.
Or how set disable encoded filename?
Thank you!

A bug in BitmapWorkerTask.cancelPotentialWork

I suppose Strings are not to be checked using == or != operator. Following code would be better:
BitmapWorkerTask task = getBitmapWorkerTask();
if(task != null) {
if(task.url != null) {
if(task.url.equals(url))
return false;
else
task.cancel(true);
}
}
return true;

Adding a WebCachedImageView programatically

Hi there! I try add a WebCachedImageView programatically in the instantiateItem method of my PageAdapter like this:

@OverRide
public Object instantiateItem(ViewGroup container, int position) {
WebCachedImageView imageView = new WebCachedImageView(context);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setImageUrl(images.get(position).getUrl());
((ViewPager) container).addView(imageView, 0);
return imageView;
}

I tried in several ways with several ScaleType's but the result was the same, show only a color, or nothing. Then I changed the method to this:

@OverRide
public Object instantiateItem(ViewGroup container, int position) {
WebCachedImageView imageView = (WebCachedImageView) inflater.inflate(R.layout.item_viewpager_page, null);
imageView.setImageUrl(images.get(position).getUrl());
((ViewPager) container).addView(imageView, 0);
return imageView;
}

And now It's working, but isn't too nice given that I have to inflate a new View in each instantiateItem call. Maybe I'm using wrong the library?. Thanks, your library rulez 👯
