Boa tarde, criei um aplicativo que baixa fotos de um link determinado, porem quero que colocar um banco de dados temporário para estas fotos, por exemplo quando eu clicar para carregar a foto ele crie um banco de dados ou temporário e armazene as fotos, dai na proxima vez que eu clicar ele nao baixe novamente a imagem, e quero criar um botão com uma forma de limpar o temporário. Sendo assim quando eu limpar ele vai baixar novamente as imagens.

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook   http://www.appinventor.org/book2 ... the links are at the bottom of the Web page.  The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro  and the aia files for the projects in the book are here:  http://www.appinventor.org/bookFiles  
How to do a lot of basic things with App Inventor are described here:  http://www.appinventor.org/content/howDoYou/eventHandling  .

Also do the tutorials http://appinventor.mit.edu/explore/ai2/tutorials.html to learn the basics of App Inventor, then try something and follow the
 Top 5 Tips: How to learn  App Inventor

You will not find a tutorial, which does exactly what you are looking for. But doing the tutorials (not only reading a little bit) help you to understand, how things are working. This is important and this is the first step to do.
