<dt>General Notes:</dt>

<dd>
|
||||
<ul>
|
||||
<li>Integrated the Data Binding Plugin into the Android Plugin for Gradle. To enable it, add
|
||||
the following code to each per-project <code>build.gradle</code> file that uses the
|
||||
plugin:</li>
|
||||
<pre>
|
||||
android {
|
||||
dataBinding {
|
||||
enabled = true
|
||||
}
|
||||
}
|
||||
</pre>
|
||||
<li>Added a new <a href="http://google.github.io/android-gradle-dsl/javadoc/1.5/" class="external-link">Transform API</a>
|
||||
to allow third-party plugins to manipulate compiled <code>.class</code> files before they’re
|
||||
converted to <code>.dex</code> files. The Transform API simplifies injecting custom class
|
||||
manipulations while offering more flexibility regarding what you can manipulate. To insert a
|
||||
transform into a build, create a new class implementing one of the <code>Transform</code>
|
||||
interfaces, and register it with <code>android.registerTransform(theTransform)</code> or
|
||||
<code>android.registerTransform(theTransform, dependencies)</code>. There’s no need to
|
||||
wire tasks together. Note the following about the Transform API:</li>
|
||||
<ul>
|
||||
<li>A transform can apply to one or more of the following: the current project, subprojects,
|
||||
and external libraries.</li>
|
||||
<li>A transform must be registered globally, which applies them to all variants.</li>
|
||||
<li>Internal code processing, through the Java Code Coverage Library (JaCoCo), ProGuard,
|
||||
and MultiDex, now uses the Transform API. However, the Java Android Compiler Kit
|
||||
(Jack) doesn’t use this API: only the <code>javac/dx</code> code path does.</li>
|
||||
<li>Gradle executes the transforms in this order: JaCoCo, third-party plugins, ProGuard.
|
||||
The execution order for third-party plugins matches the order in which the transforms are
|
||||
added by the third party plugins; third-party plugin developers can't control the execution
|
||||
order of the transforms through an API.</li>
|
||||
</ul>
|
||||
<li>Deprecated the <code>dex</code> getter from the <code>ApplicationVariant</code> class.
|
||||
You can't access the <code>Dex</code> task through the variant API anymore because it’s now
|
||||
accomplished through a transform. There's
|
||||
currently no replacement for controlling the dex process.</li>
|
||||
<li>Fixed incremental support for assets.</li>
|
||||
<li>Improved MultiDex support by making it available for test projects, and
|
||||
tests now automatically have the <code>com.android.support:multidex-instrumentation</code>
|
||||
dependency.</li>
|
||||
<li>Added the ability to properly fail a Gradle build and report the underlying error cause
|
||||
when the Gradle build invokes asynchronous tasks and there’s a failure in the worker
|
||||
process.</li>
|
||||
<li>Added support for configuring a specific Application Binary Interface (ABI) in variants
|
||||
that contain multiple ABIs.</li>
|
||||
<li>Added support for a comma-separated list of device serial numbers for the
|
||||
<code>ANDROID_SERIAL</code> environment variable when installing or running tests.</li>
|
||||
<li>Fixed an installation failure on devices running Android 5.0 (API level 20) and higher
|
||||
when the APK name contains a space.</li>
|
||||
<li>Fixed various issues related to the Android Asset Packaging Tool (AAPT) error output.</li>
|
||||
<li>Added JaCoCo incremental instrumentation support for faster incremental builds. The
|
||||
Android Plugin for Gradle now invokes the JaCoCo instrumenter directly. To force a newer
|
||||
version of the JaCoCo instrumenter, you need to add it as a build script dependency.</li>
|
||||
<li>Fixed JaCoCo support so it ignores files that aren’t classes.</li>
|
||||
<li>Added vector drawable support for generating PNGs at build time for backward-compatibility.
|
||||
Android Plugin for Gradle generates PNGs for every vector drawable found in a resource
|
||||
directory that doesn’t specify an API version or specifies an
|
||||
<code>android:minSdkVersion</code> attribute of 20 or lower in the
|
||||
<code><uses-sdk></code> element in the app manifest. You can set PNG densities by
|
||||
using the <code>generatedDensities</code> property in the <code>defaultConfig</code> or
|
||||
<code>productFlavor</code> sections of a <code>build.gradle</code> file.</li>
|
||||
<li>Added sharing of the mockable <code>android.jar</code>, which the plugin generates only
|
||||
once and uses for unit testing. Multiple modules, such as <code>app</code> and
|
||||
<code>lib</code>, now share it. Delete <code>$rootDir/build</code> to regenerate it. </li>
|
||||
<li>Changed the processing of Java resources to occur before the obfuscation tasks instead of
|
||||
during the packaging of the APK. This change allows the obfuscation tasks to have a chance
|
||||
to adapt the Java resources following packages obfuscation.</li>
|
||||
<li>Fixed an issue with using Java Native Interface (JNI) code in the experimental library
|
||||
plugin.</li>
|
||||
<li>Added the ability to set the platform version separately from the
|
||||
<code>android:compileSdkVersion</code> attribute in the experimental library
|
||||
plugin.</li>
