In r13 and before, aidl compilation, resources ID generation, dex’ing, packaging, etc.. Note: renderscript compilation is not yet checking for file modifications and will run all the time. The result should be much faster compilation times as developers work on their apps.
Android Data Binding creates a link between UI layer and the underlying data model that holds the information to display.
In normal Android app, it is necessary to find the view and update the content.
(Time as displayed by Ant after a successful build. PNG files) in the project, as well as amount and types of file changed will impact actual build times.
Average of 3 runs.)Note that actual build time gains will depend per project. This benchmark is simply meant to show the impact of skipping some unnecessary steps.
Every time data changes the User Interface widget (Text View, Image View etc.) bound to it is needs to be update.
Lots of hours were wasted on writing and maintaining trivial and almost useless code occupying tens or even hundreds of lines in almost all Activity.
Build performance has recently starting to be an issue for larger apps and the revision 14 has several fixes to help.
In this section, we’ll highlight the ones that are used by both Ant and Eclipse.
As mentioned above the build rules have been completely revamped.
We have merged the 3 previous rule files (for app, library and test projects) into a single file and have changed some of the existing targets to work more cohesively together, especially when a project needs to build other projects (such as library projects and tested app projects).
Same thing for a layout (unless you add a new @ id/foo reference!
