Alchemy app released (in beta)

I've finally published the beta version of Alchemy on the play store. It's still in beta, but it seems to be working well. Give it a shot if you're looking for a different way to donate to charity!

Memory leak with android linearlayout and Picasso

I recently ran into an issue using Picasso with Android's linearlayout. I was using Picasso to load images from a url into a linearlayout, handling errors with Picasso's build object as follows:

Picasso.Builder builder = new Picasso.Builder(this.mContext);
builder.listener(new Picasso.Listener()
{
    @Override
    public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception)
    {
      picasso.load(mThumbIds[0]).into(imageView); // on failure just load the default image
    }
});
Picasso picasso= builder.build();


I was recycling the images correctly with convertView (using a viewholder class), but I couldn't track down the source of a memory leak which occured every time a new image was loaded - eventually causing the app to crash. The leak however when away when I stopped using Picasso's builder, instead just using a simple try catch setup.

try{
    Picasso.with(mContext).load(logo_url).placeholder(R.drawable.alchemy).into(holder.imageView);
}
catch (Throwable e){
     Picasso.with(mContext).load(R.drawable.alchemy).into(holder.imageView);
}

Sending an SMS via Intent in Android

Alchemy allows users to donate to their chose charities via text message, which it used to do automatically using Android's SmsManager ...
