android - 使用 Android.mk mm 命令构建的 APK 安装后未在设备中运行

Question

我正在关注https://wladimir-tm4pda.github.io/porting/build_cookbook.html并修改了构建一个简单的 APK

Android.mk 文件位于顶层。

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)

我已将其包含在 Android 10 AOSP 中，并mm在终端中使用命令构建。

输出的 apk 有 1MB 大（应该是 5MB），之后 adb install -r -t -f LocalPackage.apk 它不会出现在应用程序列表中。在 Android Studio 中构建时，它工作正常。

我的目标是让这个应用程序成为系统应用程序，但第一步是让mm构建成功。如何纠正这种情况？

更新：

我现在将Android.mk文件的位置更改AndroidManifest.xml为存在的位置，并且还更改了我的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 := \
    androidx.core_core \
    androidx.appcompat_appcompat \
    androidx.fragment_fragment \
    android-support-constraint-layout \

LOCAL_DEX_PREOPT := false
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

现在我得到了一个 2MB 的应用程序，该应用程序在安装后显示在设备上，但是一旦我运行它并出现错误就会崩溃

我能够为我的 Kotlin Android 应用程序使用 Soong 编译。我使用了以下 Android.bp 文件。

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,
  },
}

在将 Android 应用程序完全转换为 Java 后，我还尝试编译它。这是 Android.mk 文件

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

include $(BUILD_PACKAGE)
