ad818dcbea Support java compilation sharding for target side.
Add "LOCAL_JAVAC_SHARD_SIZE" to represent the number of java
source path entries in each shard.

Sharding is not allowed when "LOCAL_JAVAC_SHARD_SIZE" and
"LOCAL_JAR_PROCESSORS" are both enabled.

Limitation:
1. 0 <= LOCAL_JAVAC_SHARD_SIZE <= 8192
1. 0 < NUM(java_sources) <= 8192
2. 0 <= NUM(shards) <= 100

Performance Compare:

f439c334da Fix incremental aapt builds
If a resource was moved / removed without any other timestamp updates,
ninja would not re-run aapt. To fix this, add a list of resource files
into the same command as aapt (echo ... >/dev/null). That way if the
list changes, ninja will recognize the command line changing and rerun
aapt.

0739155c86 Add Turbine as part of java build toolchain in Make.
1. Bundle static_java_header_libs during turbine-classes.jar if
necessary. This can be improved if we have the ability to merge jars on
the fly.

2. Copy sdk/stubs-classes.jar to sdk/stubs-classes-header.jar, and Use
.KATI_RESTAT to cut un-necessary targets rebuilt.

3. Copy prebuilt-classes.jar to prebuilt-classes-header.jar since
Turbine doesn't apply to prebuilt.

4. Run jarjar after Turbine compilation, otherwise downstream targets
won't find corresponding symbols.

5. Change classes.jar in -classpath used in Desugar to
classes-header.jar.

6. Change legacy-libs in Proguard from classes.jar to
classes-header.jar.

7. Add .KATI_RESTAT for turbine-classes.jar, and remove IJAR.

8.boot.art is re-generated during the incremental rebuild since
javalib.jar got re-generated. Then boot.art re-triggered lots of
downstream targets to be rebuilt. So we add .KATI_RESTAT for javalib.jar
to prevent downstream to be rebuilt. The ziptime & commit-change-to-toc
operation for javalib.jar(small) didn't bring too much overhead when we build
from clean state.

Next step: specify static_java_header_libs in -classpath, and merge jars
at the end.

dfc45ec337 Separate java source list generation into its own rule
Move the java source list generation step into its own rule.  This
has a couple of advantages.  It consolidates the source list
generation so that it only has to run once for javac, jack, and
jack-check.  It also massively reduces the length of the javac
command line, so that error messages are significantly shorter,
and allows easily rerunning the failing build command because
the file list is still on disk.

The primary disadvantage is that javac error messages no longer
include the list of files passed to javac, but the list is
available earlier in the build long when the file list was written,
and is still available on disk.

fa7ecfb752 Clean LOCAL_RESOURCE_DIR paths
With LOCAL_USE_AAPT2, resource directories like a/b/../res cause
problems, since ninja will canonicalize the path before creating the
intermediate resource directory, so it creates <intermediates>/a/res
while we give AAPT2 <intermediates>/a/b/../res, which fails to open.

6b68da0625 Do not package res unless RS target API < 21
Bug: 37626838

Since Lollipop, RS generated bitcode is embedded as strings in
generated Java files, and no longer needed in the resources.
This CL makes packaging resources conditional on RS target API, and
not do so unless it is below 21.

We removed code and variables related to running dx on classes.jar in
this change. Also removed target emma rules (but kept the emma rules for
host java libraries), for it's now done by Jack.
We still support to build classes.jar (and javalib.jar for static Java
libraries) using javac, because tools like javadoc need class files as
input.
Removed the obsolete install-dex-debug.

33360dd569 Running jarjar on Java resources.
Before this change, Java resources are added as a separate step
(add-java-resources-to-package) after dex is run, so jarjar isn't run on
the resource files.
With this change, we add Java resources immediately after we call javac,
so jarjar is run on the resource files (the module's own resource, as
well as resources carried by static Java libraries).
When we generate the final apk/jar, we use the jarjar'ed jar as the
inital pacakge file, with class files and empty folders removed.

When jack is enabled, in jack-java-to-dex we add the Java resources to
a temp jar using the PRIVATE_EXTRA_JAR_ARGS, and extrac the files in a
temp dir. Jack will process the resource files and output the result to
PRIVATE_JACK_INTERMEDIATES_DIR. When we package the final apk/jar, we
need to call add-carried-jack-resources to readd the resources.
(TODO: if jack can output all resources to a jar/zip file, we can use
that file as the initial package file as well.)

the resource files.
With this change, we add Java resources immediately after we call javac,
so jarjar is run on the resource files (the module's own resource, as
well as resources carried by static Java libraries).
When we generate the final apk/jar, we use the jarjar'ed jar as the
inital pacakge file, with class files and empty folders removed.

When jack is enabled, in jack-java-to-dex we add the Java resources to
a temp jar using the PRIVATE_EXTRA_JAR_ARGS, and extrac the files in a
temp dir. Jack will process the resource files and output the result to
PRIVATE_JACK_INTERMEDIATES_DIR. When we package the final apk/jar, we
need to call add-carried-jack-resources to readd the resources.
(TODO: if jack can output all resources to a jar/zip file, we can use
that file as the initial package file as well.)

f1db7e23d9 Support to build AAR for static Java libraries.
Set up rules to build $(built_aar), if a static Java library has Android
resources.
If you run "tapas my_lib && make dist", my_lib.aar will be built and put
in the DIST_DIR.

b4c49cba57 Compile using Jack.
This allows to compile dex targeted java sources using Jack and Jill.
Default is still to compile with the legacy toolchain. Default can be
switched to the new toolchain by setting environement variable:
export ANDROID_COMPILE_WITH_JACK=true
Toolchain can also be forced for one module by defining
LOCAL_USE_JACK:=true # false
in the mk portion defining the module.

Jack execution environement can be controlled with:

Global variable ANDROID_JACK_VM allow to change the jvm executing Jack.
Global variable ANDROID_JACK_VM_ARGS allows to change default args given
to the jvm.
Global variable ANDROID_JACK_EXTRA_ARGS allows to define some default args
to give to Jack

LOCAL_JACK_VM_ARGS allows to override default args given to the jvm for
the module.
LOCAL_JACK_EXTRA_ARGS allows to override default args passed to Jack.

efb935800b Support "LOCAL_SDK_VERSION := system_current"
A module can declare "LOCAL_SDK_VERSION := system_current" to build
against the android system stubs generated from source.
For now this is only supported in platform build.

dc7fee9fbf Set up rules to merge AndroidManifest.xmls
Now you can merge the library manifest files to the main app's
AndroidManifest.xml with LOCAL_FULL_LIBS_MANIFEST_FILES.
LOCAL_FULL_LIBS_MANIFEST_FILES is a list of paths relative to the top of
the source tree.

ae25ec1bcd More flexibility to keep/remove R.class in static Java library
- Usually you don't need to set LOCAL_JAR_EXCLUDE_FILES in your
  Android.mk, if your static library is directly used by an app.
- If your library will be included by another library that need
  reference the R/Manifest class, you can set
  LOCAL_JAR_EXCLUDE_FILES := none
  to keep the generated classes.
- If your library includes another static library that has Android
  resource and you want to remove the generated classes carried by
  the static library, set:
  LOCAL_JAR_EXCLUDE_FILES := $(ANDROID_RESOURCE_GENERATED_CLASSES)

With the LOCAL_JAR_EXCLUDE_FILES value "none", deprecate the old
long variable LOCAL_KEEP_R_CLASS_IN_STATIC_JAVA_LIBRARY.
