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：
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'

我的项目中有这些依赖项：
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
implementation 'com.google.android.gms:play-services-maps:16.1.0'
implementation 'com.google.firebase:firebase-database:17.0.0'
implementation 'com.google.firebase:firebase-storage:17.0.0'
implementation 'com.google.firebase:firebase-messaging:18.0.0'
implementation 'com.firebaseui:firebase-ui-storage:0.6.0'
到目前为止，似乎没有什么问题，但我得到了这样的信息：
找到版本28.0.0、23.4.0。示例包括com.android.support:动画矢量可绘制：28.0.0和支持：palette-v7:23.4。
然后我做了：
$ ./gradlew -q dependencies app:dependencies --configuration debugAndroidTestCompileClasspath >> dep.txt
在文件中，我搜索了调色板，发现它被firebase存储所使用：
\--- com.firebaseui:firebase-ui-storage:0.6.0
+--- com.android.support:appcompat-v7:23.4.0 -> 28.0.0 (*)
+--- com.android.support:palette-v7:23.4.0
添加后：
implementation 'com.android.support:palette-v7:28.0.0'
似乎已解决，没有更多错误。
//干杯
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
要查看应用程序中特定库的依赖项，请遵循以下教程：-如何在Gradle中排除特定依赖项的依赖项
希望能有所帮助
花了大约5个小时后，这个解决方案对我有效。。
如果您还没有：
xmlns:tools="http://schemas.android.com/tools"
例子：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.winanainc"
android:versionCode="3"
android:versionName="1.2"
xmlns:tools="http://schemas.android.com/tools">
然后在应用程序中添加这个元标记以覆盖构建工具版本，在本例中，我选择了25.3.1版本
<application>
...
..
<meta-data
tools:replace="android:value"
android:name="android.support.VERSION"
android:value="25.3.1" />
</application>
