android.mk引用aar

先看看引入jar (因为和引用aar很像)

LOCAL_STATIC_JAVA_LIBRARIES := dictenginelib \
                               org.apache.http.legacy \
                               constraint-layout-solver-1.1.3_ \

                               yxp_support-new-v4-media-compat-25.3.1 \

                               IntelligentLearningScheme_cupboard-2.2.0 \

                               IntelligentLearningScheme_glide_annotations-4.3.1 \
                               IntelligentLearningScheme_glide_disklrucache-4.3.1 \
                               IntelligentLearningScheme_glide_gifdecoder-4.3.1\

                               IntelligentLearningScheme_okhttp-3.8.1 \
                               IntelligentLearningScheme_okio-1.13.0

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := IntelligentLearningScheme_cupboard-2.2.0:libs/cupboard-2.2.0.jar \

                            IntelligentLearningScheme_glide_disklrucache-4.3.1:libs/glide_disklrucache-4.3.1.jar \
                            IntelligentLearningScheme_glide_gifdecoder-4.3.1:libs/glide_gifdecoder-4.3.1.jar \
                            IntelligentLearningScheme_gson-2.8.5:libs/gson-2.8.5.jar \
                            IntelligentLearningScheme_okgo-3.0.4:libs/okgo-3.0.4.jar \
                            IntelligentLearningScheme_okhttp-3.8.1:libs/okhttp-3.8.1.jar \
                            IntelligentLearningScheme_okio-1.13.0:libs/okio-1.13.0.jar \
                            constraint-layout-solver-1.1.3_:/../../library/third_jars/constraint-layout-solver-1.1.3.jar \
                            yxp_support-new-v4-annotations-25.3.1:/../../library/third_jars/support-annotations-25.3.1_.jar \

                            yxp_support-new-v4-core-ui-25.3.1:/../../library/third_jars/support-core-ui-25.3.1_.jar \

                            yxp_support-new-vector-drawable-25.3.1:/../../library/third_jars/support-vector-drawable-25.3.1_.jar \
                            yxp_support-new-animated-vector-drawable-25.3.1:/../../library/third_jars/support-animated-vector-drawable-25.3.1_.jar

• 使用LOCAL_STATIC_JAVA_LIBRARIES 要引入的jar定义一个变量名。
• 使用LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES 给定义的变量 设置一个引用路径。

再看引用aar

LOCAL_STATIC_JAVA_AAR_LIBRARIES := IntelligentLearningScheme_appcompat-v7-25.3.1 \
                                   IntelligentLearningScheme_recyclerview-v7-25.3.1 \
                                   IntelligentLearningScheme_constraint-layout-1.1.3 \
                                   IntelligentLearningScheme_utilcode-1.9.9

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := IntelligentLearningScheme_appcompat-v7-25.3.1:/../../library/aars/appcompat-v7-25.3.1.aar \
                            IntelligentLearningScheme_recyclerview-v7-25.3.1:/../../library/aars/recyclerview-v7-25.3.1.aar \
                            IntelligentLearningScheme_constraint-layout-1.1.3:/../../library/aars/constraint-layout-1.1.3.aar \
                            IntelligentLearningScheme_utilcode-1.9.9:libs/utilcode-1.9.9.aar

#需要引入library/aar的包名  
LOCAL_AAPT_FLAGS := --auto-add-overlay \
                    --extra-packages android.support.v7.appcompat \
                    --extra-packages android.support.constraint \
                    --extra-packages android.support.v7.recyclerview \
                    --extra-packages com.blankj.utilcode

• 可以发现唯一不同就是 LOCAL_STATIC_JAVA_LIBRARIES 和 LOCAL_STATIC_JAVA_AAR_LIBRARIES 。
