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
我的成绩：

解决这个问题的最佳方法是实现AndroidStudio建议的所有“com.android.support:…”
（无论您使用的是哪种支持版本–27.1.1、28.0.0等）
将光标放在错误行，例如。
implementation 'com.android.support:appcompat-v7:28.0.0'
Android Studio将向您建议“com.Android.support:…”是不同于'com.android.support:appcompat-v7:28.0.0'
实例
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28.0.0、27.1.0和27.0.2。示例包括com.android.support:animatedvector-drawable:28.0.0和com.android.com/support:exifinterface:27.1.0
所以添加com.android.support:animatedvector-drawable:28.0.0&com.android.support:exifinterface:28.0.0。现在同步渐变文件。
一个接一个地尝试实现所有建议的“com.android.support:…”，直到此行实现“com.andrio.support:appcompat-v7:28.0.0”中没有错误
就我而言，我补充道
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:exifinterface:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:customtabs:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
所有这些依赖关系，对你来说可能会有所不同。

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。
