一、如何將帶源碼的APK預置進系統？
1) 在 packages/apps 下面以需要預置的 APK的 名字創建一個新文件夾，以預置一個名為Test的APK 為例
2) 將 Test APK的Source code 拷貝到 Test 文件夾下，刪除 /bin 和 /gen 目錄
3) 在 Test 目錄下創建一個名為 Android.mk的文件，內容如下：
LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE_TAGS := optional LOCAL_SRC_FILES := $(call all-subdir-java-files) LOCAL_PACKAGE_NAME := Test include $(BUILD_PACKAGE)
4) 打開文件 device/mediatek/common/device.mk
將 Test 添加到 PRODUCT_PACKAGES 裡面。
PRODUCT_PACKAGES += Test
5) 重新 build 整個工程
二、如何將無源碼的 APK 預置進系統？
1) 在 packages/apps 下面以需要預置的 APK 名字創建文件夾，以預置一個名為Test的APK為例
2) 將 Test.apk 放到 packages/apps/Test 下面
3) 在 packages/apps/Test 下面創建文件 Android.mk，文件內容如下：
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) # Module name should match apk name to be installed LOCAL_MODULE := Test LOCAL_MODULE_TAGS := optional LOCAL_SRC_FILES := $(LOCAL_MODULE).apk LOCAL_MODULE_CLASS := APPS LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX) LOCAL_PREBUILT_JNI_LIBS:= / @lib/armeabi/libtest.so / @lib/armeabi/libtest2.so LOCAL_CERTIFICATE := PRESIGNED include $(BUILD_PREBUILT)
若無so，刪除LOCAL_PREBUILT_JNI_LIBS
若有so，使用LOCAL_PREBUILT_JNI_LIBS列出所有so的路徑，不要忘記使用@。@標識符會將apk中的so抽離出來build進apk同級目錄下的lib文件夾中
若apk支持不同cpu類型的so，針對so的部分的處理:
Ifeq ($(TARGET_ARCH),arm) LOCAL_PREBUILT_JNI_LIBS := / @lib/armeabi-v7a/xxx.so/ @ lib/armeabi-v7a/xxxx.so else ifeq ($(TARGET_ARCH),x86) LOCAL_PREBUILT_JNI_LIBS := / @lib/x86/xxx.so else ifeq ($(TARGET_ARCH),arm64) LOCAL_PREBUILT_JNI_LIBS := / @lib/armeabi-v8a/xxx.so …
即將和TARGET_ARCH對應的so抽離出來
4) 打開文件 device/mediatek/common/device.mk
將 Test 添加到 PRODUCT_PACKAGES 裡面。
PRODUCT_PACKAGES += Test
5) 重新 build 整個工程
注：如果App使用System Level的permission，需要預置到/system/priv-app底下 (原在/system/app)。
修改Android.mk，增加LOCAL_PRIVILEGED_MODULE := true，以聲明app需要放在/system/priv-app下。
三、如何預置APK使得用戶可以卸載，恢復出廠設置時不能恢復？
1) 在 packages/apps 下面以需要預置的 APK 名字創建文件夾，以預置一個名為Test的APK為例
2) 將 Test.apk 放到 packages/apps/Test 下面
3) 在 packages/apps/Test 下面創建文件 Android.mk，文件內容如下：
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) # Module name should match apk name to be installed LOCAL_MODULE := Test LOCAL_MODULE_TAGS := optional LOCAL_SRC_FILES := $(LOCAL_MODULE).apk LOCAL_MODULE_CLASS := APPS LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX) # LOCAL_PRIVILEGED_MODULE := true LOCAL_MODULE_PATH := $(TARGET_OUT_DATA_APPS) LOCAL_CERTIFICATE := PRESIGNED include $(BUILD_PREBUILT)
4) 打開文件 device/mediatek/common/device.mk
將 Test 添加到 PRODUCT_PACKAGES 裡面。
PRODUCT_PACKAGES += Test
5) 重新 build 整個工程
注意：這個比不能卸載的多了一句
LOCAL_MODULE_PATH := $(TARGET_OUT_DATA_APPS)
四、如何預置APK使得用戶可以卸載，並且恢復出廠設置時能夠恢復？
1在 vendor/mediatek/proprietary/binary/3rd-party/free下面以需要預置的 APK 名字創建文件夾，以預置一個名為Test的APK為例
2 將Test.apk 放入vendor/mediatek/proprietary/binary/3rd-party/free/Test下面
3 在vendor/mediatek/proprietary/binary/3rd-party/free/Test 下面創建文件 Android.mk，文件內容如下
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) # Module name should match apk name to be installed LOCAL_MODULE := Test LOCAL_MODULE_TAGS := optional LOCAL_SRC_FILES := $(LOCAL_MODULE).apk LOCAL_MODULE_CLASS := APPS LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX) LOCAL_CERTIFICATE := PRESIGNED LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app include $(BUILD_PREBUILT)
2 打開文件device/mediatek/common/device.mk
將 Test 添加到 PRODUCT_PACKAGES 裡面。
PRODUCT_PACKAGES += Test
3 然後重新build整個工程
請注意：
若需要apk作為32bit的apk運行，則需要在Android.mk中定義
LOCAL_MULTILIB :=32
若有lib
intel芯片 上面的方法只能導x86的
若沒x86
可以在編譯時把apk拷貝到system/usr/share/apks
編譯腳本中加入：
function build_android()
{
echo
echo '[ Build android platform ]'
echo
START_TIME=`date +%s`
check_git_dependece
if [ $BUILD_PRODUCT = "generic" ]
then
rm ./buildspec.mk
echo make -j$CPU_JOB_NUM
echo
make -j$CPU_JOB_NUM
else
get_build_mode
gen_build_ver
set_default_hw_version
gen_git_verion
source build/envsetup.sh
if [[ $BUILD_PRODUCT = "prom890bap" ]]
then
echo "copy prom890bap apk"
mkdir -p out/target/product/$BUILD_PRODUCT/system/usr/share/apks
cp device/intel/baytrail/prom890bap/apk/*.apk out/target/product/$BUILD_PRODUCT/system/usr/share/apks/
然後在第一次啟動時安裝apk
