How to improve the user experience of Android programs

1. Do not lose the data being operated. Especially in activity.

2. do not provide raw data and use the content provider for access by other programs.

3. Do not interrupt your operations. Do not enable the activity in the broadcast receiver or service.

4. Put long operations in the new thread. If the ui fails to complete the operation within five seconds, no response error is reported.

5. Do not make an activity too bloated. We recommend that you use the system's task stack.

6. extended system themes: custom theme styles for your programs.

7. Support for multiple screen resolutions and multiple screen ui displays make users feel the best.

8. If the network is slow, the progress is displayed.

9. Do not assume that the target device only has a touch screen or a hard keyboard.

10. do not consume too much power. Minimize network access and write efficient code.
