Post 1.0 Compatibility
Starting with Android Studio 1.0 and the Gradle plugin for Android 1.0, compatibility is a critical requirement.
While we are still looking at finalizing our policy you should at least expect:
Studio
1.x works with Gradle Plugin
1.y
Newer versions of the Gradle plugin may require newer versions of Studio to enable the new features in the IDE, but the project should open in older versions of Studio, and build from there (since Gradle does the build). We will be very careful about this.We will determine later our compatibility story between Studio 2.x and Gradle Plugin 1.x and between Studio 1.x and Gradle Plugin 2.xWe will make every effort to keep compatibility where possible, and to provide good Quick Assist to help with migration where applicable.
Gradle plugin
1.0.0 - 1.1.3 works with Gradle
2.2.1 - 2.3.
It does not work with Gradle 2.4+
Gradle plugin
1.2+ works with Gradle
[2.2.1, 3.0[
Newer versions of the Plugin may require a newer version of Gradle to benefit from advanced features.
However the current 1.2+ should work with [2.2.1, 3.0[(We cannot guaranteed compatibility with 3.x as it may introduce breaking changes: Gradle 1.x -> 2.0 introduced Groovy breaking changes)
| Android Studio | Android Gradle Plugin | Gradle |
| 1.0.0+ | 1.0.0 - 1.1.3 | 2.2.1 - 2.3 |
| 1.0.0+ | 1.2+ | 2.2.1+ |
Post 1.0 DSL compatibility
The DSL changed a lot before 1.0, but it should be stable now.
If/When we need to change things we will have long deprecation periods, likely longer than 6 months, possibly 12 months.
Preview Compatibility
This table indicate compatibility for pre-1.0 components.
All this breaking changes happened because we tweaked the model exchanged between the IDE and Gradle a lot. All this work was to ensure stability after 1.0.
| Android Studio | Android Gradle Plugin | Gradle |
