Thank you so much for your tutorials. I have worked up to 17 and they are the best I have found. The English is very clear and the explanations perfect. I find the way you have broken the projects down into modules that illustrate important functions very helpful. I will recommend this to all those looking for help in Android. All the best and thank you again.

And for addition, for the current version of android studio, we replace the path :
R.drawable.<imgName> into R.mipmap.<imgName>

Hi, when adding an image using New->Image Asset, I understand that from SDK 4.3 or 5.0, the images are automatically added to the mipmaps folder and not the drawables folder in the res directory. My current version of Android Studio is 1.5.1.  Thanks

[sagar]

[arapreyhan]

Terrific tutorial, as always. This example was particularly helpful because I am creating a simple app that let's users view cartoon images one at a time. If I need to display a much larger number of images, one at a time, more like 300-1000, would you recommend storing these image files in the app res folder and listing them in an array? Or would an app with a much larger collection of images need to pull them from some kind of external database? Thanks for any advice!

I began learning Java along Android developing (with these amazing tutorials), so this might be a dumb question: when and why should I use 'int' in Android Java?

Thanks.

My query is different from the tutorial. I am trying to add image into ImageView from my sd card. But the Image dimensions are not as same as the ImageView. The ImageView has height and width of match_parent. I tried scaleType = fitXY but it only filled the ImageView width wise but not height wise. If you can help me with this, it would be awesome. Thank you!

Hi I'm a bit confuse of what is going on with the code

current_image_index++;
current_image_index = current_image_index % images.length;


Now current_image_index is just an int that hasn't been assigned a number yet correct or is it 0 by default?
Would it be 1 after current_image_index++?
That means during the modulus portion image.length (which is 3) is divided by 1 where the remainder is 0 right?

Hello thanks you so much for the tutorial.

current_image_index is not initialized. so how it will understand from where to start?

[pranishshrestha]

I didn't understand the code logic for toggling image which is inside onClick() method.
