Question

您好我正在尝试将我的Android应用项目从Eclipse迁移到Android Studio。这是为Android KitKat而构建的。我忘记了我使用的Eclipse版本是什么。我正在使用Android Studio 3.0.1。我按照https://developer.android.com/studio/intro/migrate.html的说明进行操作。尝试迁移时出现此错误。请帮忙。这对我来说很重要

Answer 1

我的经验是这样的：从targetSdkVersion 21降级到19（因为我公司中约有20部电话使用android 4.4），我遇到了标题为resource android:attr/preserveIconSpacing is private的错误。

我设法以这种方式克服了这个错误：

在错误消息中，它是使用设置写入目录的，在我的情况下是：.gradle\caches\transforms-1\files-1.1\appcompat-v7-19.0.0.aar\4cd3ccb7957b0114d8e3c7a67ecc96ad\res\values\。我从该目录打开attr.xml文件，对消息中声明的整行进行了注释，即：

<attr name="android:preserveIconSpacing" />

现在，丑陋的错误消失了。我不认为这可以解决问题，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，

以前，我还尝试过修改android目录中的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，已被写保护。我关闭了所有Android Studio，没有启动Java或任何其他类似的应用程序，但是没有运气。

以前，我还尝试从目录 android-sdk \ extras \ android \ support \ v7 \ appcompat \ res \ values \ 中复制“ attr.xml”，修改了prepareIconSpacing设置，然后进行了复制它在我的res / values目录中。没有运气。

更新2018年11月5日。在另一个安装中，它不是包含字符串“”的“ attr.xml”文件。因此，我搜索了错误中指定的整个“ res”目录，并在“ values.xml”文件中找到/找到了该目录。我在那里评论。而且有效。

我希望这对某人有帮助。

Answer 2

从eclipse升级到android studio时遇到了同样的问题。我通过升级build.gradle解决了这个问题。

首先，我升级了

 buildToolsVersion

然后改变了

  compileSdkVersion 'your api level'
  minSdkVersion 'your api level'
  targetSdkVersion 'your api level'

也升级了

dependencies {
implementation 'com.android.support:appcompat-v7:'your api level''
}

这解决了我的问题

Answer 3

出于某种原因，我想使用KitKat（API级别19）来编译我的项目，而使用最新的canary（Android Studio 3.3 Canary 5）却无法正常工作（我不记得错误消息，但是我已经浪费了很多时间）由于这个原因有些时间，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Android Studio 2.3稳定版中打开项目，
打开项目的 build.gradle 文件（不是应用模块的文件！），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（如果文件中没有google()）：
```
maven {
    url 'https://maven.google.com'
}
```
打开 gradle-wrapper.properties 并将gradle版本设置为2.14.1（在选择相互兼容的插件和gradle版本时，this page很有用）：< / p>
```
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
```

错误：资源android：attr / preserveIconSpacing是私有的
