我现在将 Android.mk 文件的位置更改为 AndroidManifest.xml 所在的位置，并且还更改了我的 Android.mk.

如何使用 mm 构建我的 apk 并成功运行?
解决方案
我能够在我的 Kotlin Android 应用程序中使用 Soong 编译.我使用了以下 Android.bp 文件.
android_app {名称:Camera2Video2"，清单:AndroidManifest.xml"，特权:真实，platform_apis: 真,证书:平台"，源代码:[java/com/example/android/camera2/video/*.kt"，java/com/example/android/camera2/video/fragments/*.kt"，java/com/example/android/camera2/video/overlay/*.kt"，java/com/example/android/camera2/video/utils/*.kt"，],资源目录:[res/",],静态库:[androidx-constraintlayout_constraintlayout"，androidx.appcompat_appcompat"，androidx.localbroadcastmanager_localbroadcastmanager"，com.google.android.material_material"，androidx.exifinterface_exifinterface"，androidx.core_core"，androidx.preference_preference"，androidx.fragment_fragment"，],库:[电话通用"，],优化:{启用:假，},dex_preopt:{启用:假，},}我还尝试在将 Android 应用程序完全转换为 Java 后对其进行编译.这是Android.mk文件
LOCAL_PATH := $(call my-dir)包括 $(CLEAR_VARS)res_dir := res $(LOCAL_PATH)/resLOCAL_MODULE_TAGS := 可选#LOCAL_SDK_VERSION := 当前LOCAL_SRC_FILES := $(call all-java-files-under, java)LOCAL_RESOURCE_DIR := $(addprefix $(LOCAL_PATH)/, $(res_dir))LOCAL_USE_AAPT2 := 真LOCAL_JAVA_LIBRARIES := com.google.android.material_material \LOCAL_STATIC_ANDROID_LIBRARIES := \androidx.appcompat_appcompat \androidx-constraintlayout_constraintlayout \androidx.preference_preference \androidx.fragment_fragment \androidx.core_core \#LOCAL_DEX_PREOPT := falseLOCAL_CERTIFICATE := 平台LOCAL_PRIVILEGED_MODULE := 真#LOCAL_PRODUCT_MODULE := 真LOCAL_PACKAGE_NAME := QMediaLOCAL_PRIVATE_PLATFORM_APIS := 真包括 $(BUILD_PACKAGE)I am following https://wladimir-tm4pda.github.io/porting/build_cookbook.html and have modified Building a simple APK
The Android.mk file is at the top level.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_STATIC_ANDROID_LIBRARIES += \
android-arch-lifecycle-extensions \
android-support-v7-recyclerview \
android-support-v7-appcompat \
android-support-constraint-layout \
# Build all java files in the java subdirectory
#LOCAL_SRC_FILES := $(call all-subdir-java-files)
#Commented line just made a ~17kB apk file
LOCAL_SRC_FILES := $(call all-java-files-under, app/src/main/java)
LOCAL_RESOURCE_DIR += $(LOCAL_PATH)/app/src/main/res
# Name of the APK to build
LOCAL_PACKAGE_NAME := LocalPackage
LOCAL_SDK_VERSION := current
#Otherwise build failing
# Tell it to build an APK
include $(BUILD_PACKAGE)
I have included it in Android 10 AOSP and built using mm command in terminal.
The output apk is 1MB big (should be 5 MB) and after doingadb install -r -t -f LocalPackage.apkit does not show up in the apps list.When built in Android Studio it is working fine.
My aim is to make this app a system app but first step is making mm build succeed. How to rectify this?
UPDATE:
I now changed the location of Android.mk file to where AndroidManifest.xml is present and also changed my Android.mk.
ifeq ($(TARGET_FWK_SUPPORTS_FULL_VALUEADDS),true)
ifeq ($(TARGET_BUILD_JAVA_SUPPORT_LEVEL),platform)
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
res_dir := res $(LOCAL_PATH)/res
LOCAL_MODULE_TAGS := optional
#LOCAL_SDK_VERSION := current
LOCAL_SRC_FILES := $(call all-java-files-under, java)
LOCAL_RESOURCE_DIR := $(addprefix $(LOCAL_PATH)/, $(res_dir))
LOCAL_USE_AAPT2 := true
LOCAL_JAVA_LIBRARIES := com.google.android.material_material \
LOCAL_STATIC_ANDROID_LIBRARIES := \

LOCAL_CERTIFICATE := platform
LOCAL_PRIVILEGED_MODULE := true
#LOCAL_PRODUCT_MODULE := true
LOCAL_PACKAGE_NAME := mediadecode
LOCAL_PRIVATE_PLATFORM_APIS := true
include $(BUILD_PACKAGE)
endif
endif
Now I am getting a 2MB app and the app shows up on the device after install but crashes as soon as I run it with the error

How can I build my apk with mm and run it successfully?
解决方案
I was able to use Soong compilation for my Kotlin Android app. I used the following Android.bp file.
android_app {
name: "Camera2Video2",
manifest: "AndroidManifest.xml",
privileged: true,
platform_apis: true,
certificate: "platform",
srcs: [
"java/com/example/android/camera2/video/*.kt",
"java/com/example/android/camera2/video/fragments/*.kt",
"java/com/example/android/camera2/video/overlay/*.kt",
"java/com/example/android/camera2/video/utils/*.kt",
],
resource_dirs: [
"res/",
],
static_libs: [
"androidx-constraintlayout_constraintlayout",
"androidx.appcompat_appcompat",
"androidx.localbroadcastmanager_localbroadcastmanager",
"com.google.android.material_material",
"androidx.exifinterface_exifinterface",
"androidx.core_core",
"androidx.preference_preference",
"androidx.fragment_fragment",
],
libs: [
"telephony-common",
],
optimize: {
enabled: false,
},
dex_preopt: {
enabled: false,
},
}
I also tried compiling my Android app after converting it fully to Java. Here is the Android.mk file
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
res_dir := res $(LOCAL_PATH)/res
LOCAL_MODULE_TAGS := optional
#LOCAL_SDK_VERSION := current
LOCAL_SRC_FILES := $(call all-java-files-under, java)
LOCAL_RESOURCE_DIR := $(addprefix $(LOCAL_PATH)/, $(res_dir))
LOCAL_USE_AAPT2 := true
LOCAL_JAVA_LIBRARIES := com.google.android.material_material \
LOCAL_STATIC_ANDROID_LIBRARIES := \
androidx.appcompat_appcompat \
androidx-constraintlayout_constraintlayout \
androidx.preference_preference \
androidx.fragment_fragment \
androidx.core_core \
#LOCAL_DEX_PREOPT := false
LOCAL_CERTIFICATE := platform
LOCAL_PRIVILEGED_MODULE := true
#LOCAL_PRODUCT_MODULE := true
LOCAL_PACKAGE_NAME := QMedia
LOCAL_PRIVATE_PLATFORM_APIS := true
