Question

我正在使用/将使用Android8的嵌入式系统上工作。迄今为止，开发工作已在Android 7.1.1上进行-参考板的供应商仅支持这两个。

在Android 7.1.1中，我们将.apk文件从存储库复制到正在运行的系统中，如下所示：

PRODUCT_COPY_FILES += foo.apk:root/foo.apk

（或类似之类。）Android 8完全不允许这样做。

因此，从获得我有关AOSP信息而不是有关Android手机用户信息的少量Google热门信息中，我们正在尝试这样做（在external / foo / Android.mk中）：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := foo 
LOCAL_SRC_FILES := foo.apk 
LOCAL_MODULE_CLASS := APPS
LOCAL_CERTIFICATE := PRESIGNED

LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIIX)

include $(BUILD_PREBUILT)

...在构建中没有任何痕迹！

所以，三个问题：

我做对了吗？
如何打开$（info foo）消息？默认情况下，它们在我们的7.1.1环境中处于启用状态，而不是在8中。
我们的指南是Karim Yaghmour的嵌入式Android 。有最新的指南吗？

谢谢！

编辑：下面，针对一个问题，我将尝试添加完整的“ make foo”输出。请注意，这主要是样板，由参考板制造商修改后的发行版总是吐出：

Answer 1

将模块附加到设备makefile中的PRODUCT_PACKAGES，例如：

PRODUCT_PACKAGES += \
    foo

Answer 2

确保模块 foo 是device.mk文件的一部分（例如device / moto / shamu / device.mk）。

PRODUCT_PACKAGES += \
    foo

这将在您的system/app文件夹中生成apk。下面的标志会将您的应用转到system/priv-app文件夹。

LOCAL_PRIVILEGED_MODULE := true

您还可以将apk路径移动到供应商分区（vendor/app）。

LOCAL_MODULE_PATH   := $(PRODUCT_OUT)/$(TARGET_COPY_OUT_VENDOR)/app

Answer 3

请小心输入错误 $(COMMON_ANDROID_PACKAGE_SUFFIIX)应该是$(COMMON_ANDROID_PACKAGE_SUFFIX)。

还要确保在external / foo / Android.mk每行的末尾没有多余的空格
