Android Studio中添加应用程序兼容性V7后的错误 [英] Error after adding AppCompat v7 in Android Studio

问题描述

添加应用程序兼容性V7库我得到的错误是R不能得到解决，这显然是由于这样的事实是R现在存在两次后。我找到了答案，在这里，问题：<一href=\"http://stackoverflow.com/questions/19632137/build-errors-after-adding-fullscreen-activity-in-android-studio\">Build Android Studio中添加全屏活动

After adding the appCompat v7 library I get the error that R cannot be resolved, which is apparently due to the fact that R now exists twice. I found an answer to that problem here : Build errors after adding fullscreen activity in Android Studio

不过，我没有或无法找到该文件attrs.xml中的\\ src \\主\\资源\\值\\ attrs.xml。是否有任何其他解决这一问题，或者有人可以给我怎么做，Android Studio中？

However, I dont have or cant find the file attrs.xml in \src\main\res\values\attrs.xml. Is there any other solution to that problem or can someone give me a detailed description of how to do that in Android Studio?

非常感谢你！

推荐答案

将这个：

dependencies {
    compile 'com.android.support:support-v4:18.0.0'
    compile 'com.android.support:appcompat-v7:18.0.0'
}

和确保版本code（这里18.0.0）是在同一个文件比buildToolsVersion不高于：

and make sure the version code (here 18.0.0) is not higher than the buildToolsVersion in the same file :

android {
    compileSdkVersion 16
    buildToolsVersion "18.0.0"
}

然后重建项目。希望帮助！
噢，并确保你有通过SDK管理器中安装了正确的编译工具！实际的版本是21.0.2，我认为。

then rebuild your project. Hope that helps! Oh and make sure you have the right buildTools installed via SDK Manager! Actual version is 21.0.2 I think.
