android：在aidl文件com.android.internal.telephony.gsm.NetworkInfo中找不到类错误的导入

我正在尝试重新使用PhoneUtils.java (~/android_src/packages/apps/ Phone/src/com/android/phone/）在我的应用程序中进行了一些自定义。

我已经添加了INetworkQueryServiceCallback.aidl and INetworkQueryService.aidl进入我的应用程序文件夹（~/android_src/packages/ apps/USSDActivity/src/com/myapp/ussdactivitytest）但是当我 与 android 源一起构建我收到以下错误：

Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Aidl: com.myapp.ussdactivity <= packages/apps/USSDActivity/src/com/myapp/ussdactivitytest/INetworkQueryService.aidl

Android.mk：

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_SRC_FILES += \
        src/com/myapp/ussdactivitytest/EventLogTags.logtags \
        src/com/myapp/ussdactivitytest/INetworkQueryService.aidl \
        src/com/myapp/ussdactivitytest/INetworkQueryServiceCallback.aidl

LOCAL_MODULE := com.myapp.ussdactivity
include $(BUILD_STATIC_JAVA_LIBRARY)
include $(CLEAR_VARS)
LOCAL_STATIC_JAVA_LIBRARIES := com.android.phone.common
LOCAL_JAVA_LIBRARIES := core framework
LOCAL_AIDL_INCLUDES += $(FRAMEWORKS_BASE_JAVA_SRC_DIRS)
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_SRC_FILES += \
        src/com/myapp/ussdactivitytest/EventLogTags.logtags \

LOCAL_PACKAGE_NAME := USSDActivity
LOCAL_CERTIFICATE := platform
include $(BUILD_PACKAGE)
include $(call all-makefiles-under,$(LOCAL_PATH))

在本例中，添加以下行framework.aidl。 (平台\android-9\framework.aidl)

parcelable com.android.internal.telephony.gsm.NetworkInfo;
