更新到android studio 2.3后，我收到了这个错误消息。我知道这只是一个提示，因为应用程序运行正常，但这真的很奇怪。
所有com.android.support库必须使用完全相同的版本规范（混合版本可能导致运行时崩溃）。找到版本25.1.1、24.0.0。示例包括com.android.support:animatedvector-drawable:25.1.1和com.android.com/support:mediarouter-v7:24.0.0

所有com.android.support库必须使用完全相同的版本规范（混合版本可能导致运行时崩溃）。找到版本25.1.1、24.0.0。示例包括com.android.support:animatedvector-drawable:25.1.1和com.android.com/support:mediarouter-v7:24.0.0
当我们使用Google Play Services时，通常会出现此警告，因为它使用支持库作为依赖项。
我们大多数人都不知道我们可以覆盖Google Play Services中使用的支持库。当我们使用以下依赖项时：
implementation "com.android.support:animated-vector-drawable:25.1.1"
它隐含地依赖于com.android.support:mediarouter-v7:25.1.1。但它与谷歌Play服务的依赖性冲突，后者是com.android.support:mediarouter-v7:24.0.0。因此，我们需要通过显式使用库来重写它：
implementation "com.android.support:mediarouter-v7:25.1.1"
然后，依赖项块将包括这两个项，如下所示：
dependencies {
implementation "com.android.support:animated-vector-drawable:25.1.1"
implementation "com.android.support:mediarouter-v7:25.1.1"
...
}

在本例中，我的目标是25.3.1，并且在运行此命令时有一些针对不同版本的依赖关系。诀窍是在这个列表中识别针对以前版本的依赖项，并通过在Gradle中导入最新版本的依赖关系来覆盖这些依赖项。
对于所有情况，不仅仅是这些版本或库：
注意这个小信息窗口，它显示了一些关于错误的信息，其中显示了您必须更改和添加的示例。
在这种情况下：
找到版本25.1.1、24.0.0。示例包括com.android.support:animatedvector-drawable:25.11和com.android.support:mediarouter-v7:24.0.0
Your
support:动画矢量可绘制：25.1.1
是版本25.1.1
com.android.support:mediarouter-v7:24.0.0
版本为24.0.0，因此您必须添加具有相同版本的mediarouter：
com.android.support:mediarouter-v7:25.1.1
对于小信息窗口显示的每个示例，都要这样做，在本例中，所有没有25.1.1版本的库都要这样。
修复指定的库后，必须同步放坡，以查看需要更改的下一个库和包。
重要：如果您没有显式地使用一个或多个指定的库，并且它会给您带来错误，这意味着另一个库正在内部使用它，那么无论如何都要显式地编译它。
您还可以使用另一种方法来查看您实际编译的所有库的版本的差异（例如运行grade依赖关系报告或转到库文件），真正的目的是编译您使用的所有库，使其具有相同的版本。
以下是修复此警告的流程
建筑物玻璃
android {
compileSdkVersion ... // must same version (ex: 26)
...
}
dependencies {
...
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
compile 'any com.android.support... library' // must same version (ex: 26.0.1)
...
compile ('a library B which don't use 'com.android.support...' OR use SAME version of 'com.android.support'){
// do nothing
}
...
compile ('a library C which use DIFFERENT 'com.android.support...' (ex:27.0.1) {
// By default, if use don't do anything here your app will choose the higher com.android.support... for whole project (in this case it is 27.0.1)
// If you want to use 26.0.1 use
exclude group: 'com.android.support', module: '...' (ex module: 'appcompat-v7')
exclude group: 'com.android.support', module: 'another module'
...
// If you want to use 27.0.1 do
Upgrade `compileSdkVersion` and all 'com.android.support' to 27.0.1.
(It may be a good solution because the best practice is always use latest `compileSdkVersion`.
However, use 26 or 27 is base on you for example higher library may have bug)
}
}
查看/验证应用程序中所有库的依赖关系打开终端并运行/gradlew应用程序：依存关系
