The previous tutorials were aimed at beginners to android but over time have been getting more complex as the original camera_intent app has developed.
This tutorial series is more aimed towards the intermediate developers thought for those who have been following the previous tutorial series, feel free to watch this android performance series.

Android studio (1.5) is the editor of choice (IDE) for this tutorial series.

This tutorial series is the start of what I expect to be many so I encourage comments and feedback to improve the quality and viewing experience.

Can you make a tutorial for ImageView slider from images from Gallery

[drs]

I am trying to implement the zoom and pan features from this tutorial into an app I am developing. At the beginning, you created an intent to open an image from the gallery. Is there a way to tell android to open an image file automatically without having to select it manually?
I'm thinking of adding my picture to the assets folder, but I'm unsure of how to reference it from there.
Thanks!
