我在这个网站上尝试了很多解决方案,但问题仍未解决.问题是由于Android X库.当我添加Android X时,此问题已得到解决,但它开启了新问题.我不想添加Android X.如何解决这个问题？

早些时候这个错误即将来临:

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:19:5-142:19 to override.

我添加后tools:replace="android:appComponentFactory",出现此错误:

 java.lang.RuntimeException: Manifest merger failed with multiple errors, see logs
at com.android.builder.core.AndroidBuilder.mergeManifestsForApplication(AndroidBuilder.java:540)    
at com.android.build.gradle.tasks.MergeManifests.doFullTaskAction(MergeManifests.java:173)

合并错误(在Android Manifest中):

错误:工具:替换为line:2指定属性android:appComponentFactory,但没有指定新值的应用程序主清单(此文件),第1行

表现:

<?xml version="1.0" encoding="utf-8"?>
<manifest
    package="com.example"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:replace="allowBackup, android:appComponentFactory"
    android:allowBackup="false">

    ...

    <application
        android:name="com.example"
        android:icon="@mipmap/icon"
        android:debuggable="true"
        android:hardwareAccelerated="false"
        android:largeHeap="true"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        android:allowBackup="false"
        tools:ignore="GoogleAppIndexingWarning,HardcodedDebugMode">
       ...

模块级build.gradle中的依赖项块:

Manifest merger failed : Attribute …

我收到以下错误,我不知道为什么会发生这种情况.

在Windows上的ODBC(64位)下选择数据源时,我得到两个可用的MySQL数据库选项:

• MySQL ODBC 5.3 ANSI驱动程序
• MySQL ODBC 5.3 Unicode驱动程序

这两者有什么区别？

什么是Uri Matcher android.content.UriMatcher

如何使用它？有人可以解释以下三行代码的含义吗？

  uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
  uriMatcher.addURI(PROVIDER_NAME, "cte", uriCode);
  uriMatcher.addURI(PROVIDER_NAME, "cte/*", uriCode);
  int res = uriMatcher.match(uri);

我正在使用NDK支持并收到此错误:

摇篮:

分配: gradle-2.5-all

构建工具: gradle-experimental:0.2.1

XML:

    <vector android:height="24dp" android:viewportHeight="125.0"

<path android:fillColor="#FF000000" android:pathData="M97.01,-2.98,-3C47.02,95.35"/>
</vector>

警告:

vector需要API级别21(当前min为13)或使用Android Gradle插件1.4或更高版本构建

例外:

当我运行模拟器时,我收到以下错误:

无法在模拟器中启动AVD.

输出:启用Hax qemu-system-x86_64.exe:-drive if = none,index = 1,id = cache,file = {path_to_SDK}\SDK.android\avd {AVD_name} .avd/cache.img:不能打开磁盘映像{path_to_SDK}\SDK.android\avd {AVD_name} .avd/cache.img:

无效的论点

Hax ram_size 0x40000000

HAX正在运行,模拟器以快速virt模式运行.接受连接,中止时出错

AVD规格如下:

操作系统:Android 6.0 Google API

内存:1GB

决议:1440x2560

在Android Studio 2.0 Beta 6,Windows 10上运行.

我有一个xml文件,我展示了它的一小部分,以显示我想要的内容

<media:content medium="image" url="http://msnbcmedia.msn.com/j/MSNBC/Components/Photo/_new/111010-romney-health-4p.thumb.jpg">
                <media:credit role="provider">Getty Images file</media:credit>

            </media:content>

现在我想检索URL选项卡.我是怎么做到的

我做了以下代码

if(parser.getName().equalsIgnoreCase("media:content"))
{
    Log.d("media count-->",parser.getAttributeCount()+"");
}       

所以这给了我-1.

嘿,如果有人给我提示我如何获得图像网址.

我正在尝试着色Space小部件.我尝试使用android:foreground和android:background属性,但它仍然显示透明视图.

 <android.support.v4.widget.Space
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:foreground="@android:color/black"
    android:background="@android:color/black" />

文件说:

fun bundleOf(vararg pairs: Pair<String, Any?>): Bundle

返回一个新的Bundle,其中给定的键/值对作为元素.

我试过了:

   val bundle = bundleOf {
       Pair("KEY_PRICE", 50.0)
       Pair("KEY_IS_FROZEN", false)
   }

但它显示错误.

应该是什么价值:

compileSdkVersion
targetSdkVersion

我已下载并安装了Android P Developer Preview SDK,系统映像和构建工具.

我试过"28",但它显示了这个错误:
