I'm trying to learn how to compile an app in android source. The app is just a simple hello world application. I followed instructions from Making an app in the Android Source compile into system/app instead of data/app? and a couple of other sources. But when I make the application the apk file is written to obj/APPS with suffix intermediates instead of system/app and fails to show up in the emulator when I boot up. Please find below the Android.mk file.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := tests
LOCAL_MODULE_PATH := system/app
LOCAL_UNINSTALLABLE_MODULE := true
LOCAL_SDK_VERSION := current
LOCAL_PACKAGE_NAME := MyApplication
LOCAL_STATIC_JAVA_LIBRARIES := android-support-v4
LOCAL_STATIC_JAVA_LIBRARIES += android-support-v7-appcompat
LOCAL_STATIC_JAVA_LIBRARIES += android-support-v7-gridlayout
LOCAL_STATIC_JAVA_LIBRARIES += android-support-v13
LOCAL_STATIC_JAVA_LIBRARIES += android-support-design
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/res
LOCAL_RESOURCE_DIR += prebuilts/sdk/current/support/v7/appcompat/res
LOCAL_RESOURCE_DIR += prebuilts/sdk/current/support/v7/gridlayout/res
LOCAL_RESOURCE_DIR += prebuilts/sdk/current/support/design/res
LOCAL_CERTIFICATE := platform
LOCAL_AAPT_FLAGS := --auto-add-overlay
LOCAL_AAPT_FLAGS += --extra-packages android.support.v7.appcompat:android.support.v7.gridlayout
include $(BUILD_PACKAGE)

include $(CLEAR_VARS)
include $(BUILD_MULTI_PREBUILT)
# Use the following include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))
I make the application by going to the application directory in packages/apps and doing 'mm'. Is there anything I'm missing here?
Find out the BoardConfig.mk and add this :
PRODUCT_PACKAGES += MyApplication
AOSP build system will build every Android.mk, but only packages defined in BoardConfig will be put into the final product path.
