5 | ## Code Guide : How to create Snapchat-like image stickers and text stickers
6 |
7 | After spending 2000+ hours and releasing 4+ successful apps working with
8 | image transformations, we’ve decided to share our experience with the community.
9 |
10 | ## Task
11 |
12 | So the task is pretty simple: **add the ability to move, scale and rotate stickers on Android**.
13 |
14 | Even though it sounds easy, there are a couple of challenges as well.
15 | First, there is a zillion of screen sizes of Android devices, and we’d better
16 | support them all (or as many as we can). Moreover, it could be the case
17 | that you would need to enable users to save/edit their selfies. And if
18 | they open their custom works on other devices — the screen size might
19 | change, the loaded images might be of a different quality, etc.
20 |
21 | As you might have guessed, the task is getting more complicated now.
22 |
23 | **The solution needs to work on different screen sizes and be independent of the image quality**.
24 |
25 | **In the second part we've also added an ability to create text stickers,
26 | update them, and manipulate in the same way as with image stickers**.
27 |
28 | ## Solution
29 |
30 | **MotionViews-Android** - is fully functional app that meets the requirements.
31 |
32 | Check the Medium articles [How to create Snapchat-like stickers for Android](https://medium.com/uptech-team/how-to-create-snapchat-like-stickers-for-android-50512957c351)
33 | and [How to create beautiful text stickers for Android](https://medium.com/uptech-team/how-to-create-beautiful-text-stickers-for-android-10eeea0cee09) about the details of the implementation.
34 |
35 | Feel free to use the code for your own purposes.
36 |
37 | Check out the app on [Google Play](https://play.google.com/store/apps/details?id=team.uptech.motionviews).
38 |
39 | Play with the online app emulator on [Appetize.io](https://appetize.io/app/kd51amwzp7fg4f8wrrb5mz673w).
