A small Android library that backports Lollipop-style activity and fragment transitions to devices running Android API 14+. It lets developers launch shared-element-like transitions between screens with a few lines of Java code.
Use cases
- add activity transitions on pre-Lollipop Android devices
- implement shared element animation between activities
- animate fragment transitions on older Android versions
- add exit animations when pressing back
- use transitions with startActivityForResult
When to choose
- you maintain a legacy Android app supporting API 14+ devices without Lollipop transition APIs
- you want a minimal Java library for activity/fragment transition backporting
When to avoid
- your minSdkVersion is 21 (Lollipop) or higher, since the platform provides transitions natively
- you are starting a new project, as the library is unmaintained with no license and last released in 2017
- you prefer Kotlin-first or Jetpack-based transition solutions
