Android version backward compatibility

Differences between Android support V4, V7, and v13 and their application scenarios

N has not been running Android for a long time. In the past, 2.2 was just released, and now android has been updated to 4.3. In the past, the market share of various Android SDK versions showed that, 1.6 and 2.1 still occupy a certain market, so sometimes we have to consider compatibility with these versions.

Google provides Android support library package series packages to ensure lower compatibility for SDK development in later versions. during Development of X, some features of the higher version can be used in versions such as 1.6, such as fragement and viewpager. The following describes the differences between these versions:

Android
Support V4: this package is designed to take care of version 1.6 and later. This package is the most widely used. It is included by default when eclipse creates a new project.

Android
Support V7: this package is designed to take care of Version 2.1 and later, but does not include lower. Therefore, if you do not consider version 1.6, we can add this package. Also note that, v7 depends on the V4 package, that is, the two must be included at the same time.

Android
Support v13: this package is designed for Android 3.2 and later versions. It is generally not commonly used and can be used in tablet development.
