無法在android系統應用程序中導入（導入com.android.internal.statusbar）語句

Question

試圖從AOSP中的系統android應用程序中刪除通知欄。 但是無法在我的代碼中導入（導入com.android.internal.statusbar和導入android.app.StatusBarManager）。

import com.android.internal.statusbar.IStatusBarService;
import android.app.StatusBarManager;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
        StatusBarManager mStatusBarManager = (StatusBarManager) 
getSystemService(Context.STATUS_BAR_SERVICE);
        mStatusBarManager.disable(StatusBarManager.DISABLE_EXPAND);
}

Android.mk

LOCAL_PATH := $(call my-dir)


include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_STATIC_JAVA_LIBRARIES := \
    android-support-v7-recyclerview \
    android-support-v13 \
    android-support-v17-leanback \
    android-support-v7-appcompat

LOCAL_SRC_FILES := $(call all-java-files-under, src) \
    $(call all-java-files-under, WallpaperPicker/src) \
    $(call all-proto-files-under, protos)

LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/WallpaperPicker/res \
    $(LOCAL_PATH)/res \

LOCAL_PROGUARD_FLAG_FILES := proguard.flags

LOCAL_PROTOC_OPTIMIZE_TYPE := nano
LOCAL_PROTOC_FLAGS := --proto_path=$(LOCAL_PATH)/protos/
LOCAL_AAPT_FLAGS := \
      --auto-add-overlay \
--extra-packages android.support.v7.recyclerview

 LOCAL_SDK_VERSION := current
 LOCAL_PACKAGE_NAME := PlayerLauncher
 LOCAL_PRIVILEGED_MODULE := true

 LOCAL_OVERRIDES_PACKAGES := Home Launcher2
 include $(BUILD_PACKAGE)
 include $(CLEAR_VARS)
 LOCAL_SRC_FILES := $(call all-java-files-under, util) \
 $(call all-proto-files-under, protos)

 LOCAL_PROTOC_OPTIMIZE_TYPE := nano
 LOCAL_PROTOC_FLAGS := --proto_path=$(LOCAL_PATH)/protos/

 LOCAL_MODULE_TAGS := optional
 LOCAL_MODULE := launcher_protoutil_lib
 LOCAL_IS_HOST_MODULE := true
 LOCAL_JAR_MANIFEST := util/etc/manifest.txt

 include $(BUILD_HOST_JAVA_LIBRARY)

  include $(CLEAR_VARS)
  LOCAL_IS_HOST_MODULE := true
  LOCAL_MODULE_CLASS := EXECUTABLES
  LOCAL_MODULE_TAGS := optional
  LOCAL_MODULE := launcher_protoutil

  include $(BUILD_SYSTEM)/base_rules.mk

  $(LOCAL_BUILT_MODULE): | 
  $(HOST_OUT_JAVA_LIBRARIES)/launcher_protoutil_lib.jar
  $(LOCAL_BUILT_MODULE): $(LOCAL_PATH)/util/etc/launcher_protoutil | 
  $(ACP)

  $(copy-file-to-new-target)
  $(hide) chmod 755 $@
 INTERNAL_DALVIK_MODULES += $(LOCAL_INSTALLED_MODULE)
 include $(call all-makefiles-under,$(LOCAL_PATH))

你能幫我看看Android.mk文件中添加了哪些類型的庫。 編譯系統android應用程序AOSP SDK時出錯。

您的應用程序具有特權（具有系統權限），但尚無權訪問系統API（例如android.app.StatusBarManager ）。 要獲得訪問權限，您需要使用平台證書對您的應用進行簽名。

將其添加到您的Android.mk ：

LOCAL_CERTIFICATE := platform
