Question

尝试从AOSP中的系统Android应用程序中删除通知栏。但是无法在我的代码中导入（导入com.android.internal.statusbar和导入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)

  include $(CLEAR_VARS)

你能帮我看看添加了什么类型的库 Android.mk文件。编译系统android应用程序AOSP SDK时出错。

的旧命令

Answer 1

您的应用具有特权（具有系统权限），但尚未访问系统API（例如android.app.StatusBarManager）。为了获得访问权限，您需要使用平台证书对应用进行签名。

将此添加到您的Android.mk：

LOCAL_CERTIFICATE := platform

无法在android系统应用程序
