嗨，我正在尝试将我的Android应用程序项目从Eclipse迁移到Android Studio。这是为Android KitKat构建的。我忘记了我使用的 Eclipse 版本是什么。我使用的是Android Studio 3.0.1。我按照这里的指示 https://developer.android.com/studio/intro/migrate.html。我在尝试迁移时收到此错误。请帮忙。这对我来说意义重大

这是 Gradle 控制台上的错误消息

从 eclipse 升级到 android studio 时遇到了同样的问题。我通过升级build.gradle解决了它。
首先，我升级了
buildToolsVersion
然后改变了
compileSdkVersion 'your api level'
minSdkVersion 'your api level'
targetSdkVersion 'your api level'
还升级了
dependencies {
implementation 'com.android.support:appcompat-v7:'your api level''
}
这解决了我的问题
我的经验是这样的：从targetSdkVersion 21降级到19后(因为我公司大约有20部手机使用android 4.4)，我遇到了标题中的错误：resource android:attr/preserveIconSpacing is private。
我设法以这种方式忽略了此错误：
在错误消息中，它被写入了带有设置的目录，在我的情况下是：.gradlecachestransforms-1files-1.1appcompat-v7-19.0.0.aar4cd3ccb7957b0114d8e3c7a67ecc96adresvalues.我从该目录中打开了attr.xml文件，评论了消息中规定的整行，即：
<attr name="android:preserveIconSpacing" />
现在丑陋的错误消失了。我不相信这可以解决问题，因为它听起来像是一个缓存目录并且可以被覆盖，但事实并非如此，它起作用了。
以前我也尝试从android目录中修改attr.xml文件，我认为这是解决方案，即android-sdk\extras\android\support\v7\appcompat\res\values\attr.xml。但是该文件无法修改，它是写保护的。我关闭了所有Android工作室，没有启动java或任何其他类似的应用程序，但没有运气。
以前我也尝试从目录android-sdk\extras\android\support\v7\appcompat\res\values\复制"attr.xml"，修改了preserveIconSpacing设置，然后将其复制到我的res/values目录中。没有运气。
更新 2018-11月-05.在另一个安装中，它不是包含字符串"的"attr.xml"文件。所以我搜索了错误中指定的整个"res"目录，并在"values.xml"文件中找到/定位了它。我在那里评论了它。它奏效了。
我希望这对某人有所帮助。
出于某种原因，我想使用 KitKat(API 级别 19)编译我的项目，但使用最新的金丝雀(Android Studio 3.3 Canary 5)这样做不起作用(我不记得错误消息，但我因此浪费了相当多的时间，并认为它可能会对遇到相同问题的人有所帮助)。
我做了以下事情：
- 在安卓工作室2.3稳定版中打开项目，
-
打开我的项目的build.gradle文件(不是应用程序模块的文件！)并将插件版本设置为2.2.3：
dependencies { classpath 'com.android.tools.build:gradle:2.2.3' } -
将项目的build.gradle中的
google()替换为(如果您的文件中没有任何google())：maven { url 'https://maven.google.com' } -
打开Gradle-wrapper.Properties并将 Gradle 版本设置为 2.14.1(此页面在选择相互兼容的插件和 Gradle 版本时很有用)：
