Android Guidelines and Tips
. Sidebars are not easy to use on touchscreens
. Fingerprints are more visible on darker backgrounds
. There must be a way to go back or undo an action, as touching the wrong item is done quickly
. The full screen should be used
. Common operations directly visible on screen
. Minimize keyboard input
Icons & Buttons
. Buttons should have the right size and be suitable to big fingers
. Buttons should remain in the same place of the screen to avoid confusion
. Natural and consistent icons
. Buttons that have the same function should have the same color
. keep text simple and clear
. Short sentences and paragraphs are better readable
. The usage of headers will make a text better readable
. Bullets for lists will make a text better readable
. Typing text in a text box should start with an uppercase letter
. The font size should be big enough, not too big and not too small
Contextual menus are used very often, it should not be overloaded because it has to be used quickly
. Confirmation messages should be avoided, a click performs the action directly
. When the app starts downloading a lot of data, the user should be warned
Android Testing Tips
Use a real Android phone, not an emulator. Some things you just can’t know if you run an app on an emulator.
Mobile apps are most often used in short snippets of time and will be opened and closed many times. Therefore, test the closing of the app from different states and check if it re-opens in the same state.
If possible try testing the app on different Android devices an operating system versions.
End users typically find more problems (bugs) than a limited set of testers, so let other users (family/friends) help. Research has shown that 6-9 users is most efficient.
If you have decided to involve more users, search for different types of users. For example, users with a different age, handicap or experience can find other usability problems. Bear in mind the target audience for the mobile application.
Android detects a change in orientation when the user turns the device so that the display is “landscape” (long edge is horizontal) instead of “portrait” (long edge is vertical). Perform this in different states and check if the screen and state is still the same.
