Make it easier to enable obfuscation and optimization.
With this change, use:
* LOCAL_PROGUARD_ENABLED := obfuscation # to enable obfuscation
* LOCAL_PROGUARD_ENABLED := optimization # to enable optimization
* LOCAL_PROGUARD_ENABLED := obfuscation optimization # to enable both
Now the meaning of the LOCAL_PROGUARD_ENABLED options:
* full:
Use the build system's default configurations:
with shrink but no obfuscation or optimization,
global proguard flags in build/core/proguard.flags
are applied.
* custom:
The same as "full" except no aapt-generated resource-related
proguard flags.
* nosystem:
Don't use any build system's default configurations; but
aapt-generated proguard flags are still applied. You are
responsible for any other flags.
* disabled:
Disable proguard.
* obfuscation:
The same as "full" but with obfuscation enabled.
* optimization:
The same as "full" but with optimization enabled.
* no value (the default):
The build system chooses the proper value: "full" if it's an
app; "disabled" if it's a library.
You can use more than 1 of them in a meaningful combination,
for example:
LOCAL_PROGUARD_ENABLED := obfuscation optimization
