Android Propose Motion is a Touch Animation engine with easy motion implementation
In other words, Propose provides an API to implement dynamic-interaction.
If you use Propose, you can create motion with just a few lines of code.

One of the hardest things to think about when developing a mobile app is

• It was to create dynamic-interaction (motion) that attracted attention in the app.
• It’s not like what you’ve done in the factory.
• Developers will want to create compelling apps that are memorable for people, and active apps like games.

But I could not find a way to do it easily.

In general, you should use a code consisting of 1000 lines to create the motion as above
This is because algorithms are needed to represent physical coordinates and views.
If you need to do more, you will need to use a game engine. If you use an engine, you will not be able to use the skills and APIs and resources of Android.

Below you can see how easy it is to develop motion with the introduction video.

Benefits and Applications

A common development method for touch motion redefines canvas and consumes significant development costs, such as touch operations.
Using Propose, you can implement easy motion and simple code maintenance.
Below is a comparison of general development and Propose when developing a 3D Flip screen.

General Development VS Android Propose Motion

Android Propose Motion development environment

Development environment Android SDK 3.0 or later. You can move views simply using the animation. However, if you want to make views move with acceleration following the finger just like flinging, it won’t be simple anymore. However, with the help of Propose, you can easily implement flinging motion.

Propose grants motion properties to property animation of Android.
In other words, touch related gestures can be easily conneceted to the property animation.
If you’re aware of property animation, you’re ready to use Propose.

Android Propose Motion Import

You can import libraries by adding the following code to your Android Gradle file

compile 'com.markjmind.propose: propose: 1.1. +'

Note: Gradle is a defalut build tool for Android, and Propose is automatically downloaded from JCenter.
