【问题描述】：
我在下面一行收到警告
implementation 'com.android.support:appcompat-v7:28.0.0'
警告：
All com.android.support libraries must use the exact same version specification
(mixing versions can lead to runtime crashes).
Found versions 28.0.0, 24.0.0.
Examples include com.android.support:animated-vector-drawable:28.0.0
and com.android.support:mediarouter-v7:24.0.0
Inspection info:There are some combinations of libraries, or tools and libraries,
that are incompatible, or can lead to bugs.
One such incompatibility is compiling with a version of
the Android support libraries that is not the latest version
(or in particular, a version lower than your targetSdkVersion).
Issue id: GradleCompatible
下面是我的 build.gradle(app) 代码（Firebase 库的新更新）
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.vanessa.orderfoodserver"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
//Add Library

}

我已经尝试添加
com.android.support:support-v4:28.0.0
com.android.support:animated-vector-drawable:28.0.0
com.android.support:mediarouter-v7:28.0.0
但警告仍然存在。
我可以运行我的应用程序，但我仍想修复此警告。谢谢！
【问题讨论】：
-
您添加的库之一使用的是旧版本，您需要更新它。
-
@KaranMer 嗨，我检查了 Google 的 Maven 存储库：dl.google.com/dl/android/maven2/index.html，并将我的所有库更新到最新版本，但警告仍然存在
-
检查他们可能导致此问题的第三方库，尝试使用他们的最新版本。
-
您也可以尝试通过排除这些库来排除支持包，在定义依赖项后添加它。
