When it comes to UI design, it doesn’t matter if you’re designing for Android or iOS apps. UI design is vital in attracting users.

To provide you with the tools you need to create effective UI design, here are the top 15 Android UI tools that are very useful in creating the perfect mobile app user interface.

1. Android Developers (Free)

Advantages: Comprehensive material design guide & resources

As the official website for the development of Android system, Android Developers uses a new design concept inspired by paper ink to provide a feeling of peace of mind.

As the official website for the development of Android systems, this tool uses a new design concept inspired by paper and ink to provide a distraction-free environment.

Based on material design, Android Developer provides a very comprehensive mobile application UI design guide including icons, color tools, sports, styles, layouts, components, patterns, etc., thus providing the latest standards in Android interface design. Their goal is "to create a visual language for users that combines the classic principles of good design with the innovation and possibilities of technology and science."

2. Mockplus (Free-$199/year)

System: Mac & Windows

Advantage: Rapid prototype design for Android/iOS

Mockplus is a simple and quick prototyping tool for Android/iOS mobile apps with rich and comprehensive mobile application interface design components and icon libraries. It has a component library including elements for both Android and iOS application interface design, as well as the very best Android and iOS style icons and buttons.

Mockplus makes mobile application prototyping easy and simple. The material design style components follow Android official design guidelines, including the Android status bar, bottom navigation bar, and Android switch. All are ready-made for designers to use. Interaction settings between components, pages, and the interactive command panel are as plain as daylight.

In addition to rich components and icons, Mockplus also provides mobile app and web design templates to make the learning curve easy for users.

Instant preview also helps to adjust the design of the Android UI interface in order to achieve the most realistic interface design effect. So Mockplus provides 8 kinds of preview modes allowing users to view the actual design effects on different devices and in different environments.

As a brand-new collaboration and hand-off tool, Mockplus Cloud has powerful plugins that support to import files from Photoshop, Adobe XD, and Sketch. With the help of plugins, it is possible to generate specs and assets automatically for UI designer’s use.

3. Sketch ($99)

System: Mac

Advantages: Completely for "interface" design

Sketch is a lightweight, easy-to-use vector design tool that makes UI design simpler and more efficient. The platform simplifies the features used in Photoshop and Illustrator, designed specifically for UX/UI design. Before Sketch, designers had to switch between Photoshop and Illustrator to get specific features such as vector and other photo effects. Now, Sketch allows users to get rid of the bloated functionality and focus on user experience/user interface design to get the most out of their UI design. One of the best features of Sketch is the ability to install plugins to compensate for features not included in the software.

However, even though it is one of the most practical tools for designing Android App user interfaces, Sketch's support for real-time preview of the Android side is not very effective. Users need to download SkalaPreview, and only after a series of cumbersome operations can they view the actual design of the Android interface on the phone side.

4. Zeplin (Free – $100/month)

System: Mac & Windows

Advantage: Collaboration tool for UI designer and development engineer

Zeplin is very easy to use. First, the user imports the Sketch UI interface into the app. Then the application will then automatically perform a series of recognition actions. The right side displays information such as the color and font of the UI interface. When the mouse moves to the icon of the UI interface, the application will automatically display function icon position, size and other parameters. In addition, Zeplin also supports modifying rules such as adding color swatches, changing fonts, and converting programming languages between Object-C and Swift.

Users can also mark directly on the UI, add text notes, and more. For multiple users, the changes are synced so that everyone has the same version.

As a result, Android interface designers can save time focusing on the design itself without the huge time cost associated with teamwork.

5. Iconjar（Free - €24.99）

System: Mac

Advantage: Icon collection platform

Iconjar is a UI design tool that is very simple, functional and practical for Android UI design. It supports SVG/PNG/GIF icon formats. With the drag-in import management, you can set multiple "Set" combinations to manage the classification of the icon.

When you right-click or double-click on a single icon, you can only see the delete option. While you cannot see the preview function, you can control the icon display size through the icon size adjustment slider at the bottom toolbar. Other features include search and batch rename/label function (hold down the CMD key multiple choice icon, and then set the icon name and label in the right column.)

Iconjar has a detailed classification of icon, which contains material design, an important Android UI design style.

3. Pull To Refresh: drop-down list to refresh the current page content effect
