以訊飛為例:

 1. \vendor\mediatek\proprietary\packages\3rd-party 在此目錄下新建檔案如 iflyIME

 2.在iflyIME中匯入訊飛apk  改名為 iflyIME(資料夾名字與apk名字必須相同)
 
 3.新增Android.mk 檔案  
     Android.mk：
         LOCAL_PATH := $(call my-dir)

         include $(CLEAR_VARS)
         #Module name should match apk name to be installed
         LOCAL_MODULE := iflyIME
         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
         LOCAL_MULTILIB :=32
         LOCAL_PREBUILT_JNI_LIBS:= \
         @lib/armeabi/libcom_iflytek_inputmethod_mmp.so \
         @lib/armeabi/libcom_iflytek_inputmethod_ocr.so \
         @lib/armeabi/libcom_iflytek_inputmethod_setting.so \
         @lib/armeabi/libcom_iflytek_inputmethod_thirdbkservices.so \
         @lib/armeabi/libcom_iflytek_inputmethod_translate.so \
         @lib/armeabi/libdexopt.so \
         @lib/armeabi/libencdec-jni-v1.so \
         @lib/armeabi/liblwl.so \
         @lib/armeabi/libMetaVAD-v1.so \
         @lib/armeabi/libmsc-v9.so \
         @lib/armeabi/libnalsocket.so \
         @lib/armeabi/libNativeCrashCollect.so \
         @lib/armeabi/libsmartaiwrite-jni-v31.so \
         @lib/armeabi/libvadLib-v5.so \
         @lib/armeabi/libvipfont.so 
         
         include $(BUILD_PREBUILT)


  注：如@lib/armeabi/libcom_iflytek_inputmethod_ocr.so \需要用360壓縮開啟apk 獲取  後面需要空格+\ 最後一個不用加 

 4.	在 build/make/target/product/core.mk或device/mediatek/common/device.mk或     device\mediateksample\xxxx\device.mk 中新增PRODUCT_PACKAGES += facebook
     如：device\mediateksample\xxxx\device.mk （xxxx-是分支，根據不同的分支區分專案，android 8.1 在devices下sample中新增）
     
            PRODUCT_PACKAGES += iflyIME
            #PRODUCT_PACKAGES += ServiceController
            #PRODUCT_PACKAGES += TestApp
            # PRODUCT_PACKAGES += TF-OTA

       只需要這四步，就能把應用預製到我們的系統中了
