Android.mk引用aar包

aar是Android Archive檔，在Anroid.mk中使用aar包有三步驟:

1. 先把這些aar模組設定成prebuilt

把aar包下載回來，假設aar包都放在lib目錄內，寫個獨立的Android.mk設為prebuilt

include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBARRIES += {aar-package-name-1}:lib/{aar-file-name-1}.aar
LOCAL_PREBUILT_STATIC_JAVA_LIBARRIES += {aar-package-name-2}:lib/{aar-file-name-2}.aar

...
include $(BUILD_MULTI_PREBUILT)

2. 表明加入需要使用aar包

LOCAL_STATIC_JAVA_AAR_LIBRARIES += {aar-package-name-1}
LOCAL_STATIC_JAVA_AAR_LIBRARIES += {aar-package-name-2}
...

3. 並加入aar的class名稱

編譯程式才會找的到LOCAL_AAPT_FLAGS += --auto-overlay
LOCAL_AAPT_FLAGS += --extra-packages {aar-class-name-1}
LOCAL_AAPT_FLAGS += --extra-packages {aar-class-name-2}
...
