android apk應用系統整合編譯錯誤問題

在系統源碼中添加一個APK源碼目錄，並寫了相應的android.mk檔案，編譯時間出錯如下：

make: *** No rule to make target `out/target/common/obj/JAVA_LIBRARIES/liba71S_intermediates/javalib.jar', needed by `out/target/common/obj/APPS/My_Settings_intermediates/classes-full-debug.jar'. Stop.
make: *** Waiting for unfinished jobs....

按之前的經驗，嘗試了幾種方法，發現都沒有解決，後來定位到android.mk檔案寫的有問題

修改前：

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_JAVA_LIBRARIES := bouncycastle telephony-common
LOCAL_STATIC_JAVA_LIBRARIES := android-support-v4 testinterface

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-java-files-under, src)

LOCAL_PACKAGE_NAME := My_Settings
LOCAL_CERTIFICATE := platform

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES :android-support-v4:libs/android-support-v4.jar testinterface:libs/testinterface.jar

include $(BUILD_PACKAGE)

# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))

上述編譯會出錯，

修改後，編譯ｏＫ

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_JAVA_LIBRARIES := bouncycastle telephony-common
LOCAL_STATIC_JAVA_LIBRARIES := android-support-v4 testinterface

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-java-files-under, src)

LOCAL_PACKAGE_NAME := My_Settings
LOCAL_CERTIFICATE := platform

include $(BUILD_PACKAGE)

include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES :android-support-v4:libs/android-support-v4.jar testinterface:libs/testinterface.jar
include $(BUILD_MULTI_PREBUILT)

# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))

其他說明：

1.要使用ｍｍ命令單獨編譯某個模組或者應用，首先需要在JB目錄下全部編譯一次。

如果斷開編譯伺服器（如關機後第二天再次需要單獨編譯）後，想再次單獨編譯，只需要設定項目環境，當然前提是你之前編譯過一次，並且沒有clean過。設定項目編譯環境命令：1. source build/envsetup.sh 2. lunch project_number

2.如果你的模組或者應用的android.mk裡面配置LOCAL_MODULE_TAGS := optional ，則需要把LOCAL_PACKAGE_NAME 對應的名字添加到系統的PRODUCT_PACKAGES +=中，如PRODUCT_PACKAGES +=My_Setting \

3.其他具體編譯錯誤，再根據具體的log資訊處理
