如果引用的第三方库的支持库版本低于(或者不一致)app build.gradle中的支持库版本，可能会出现如下问题：
all com.android.support libraries must use the exact same version specification(mixing versions can lead to runtime crashes)
如下图所示：
去改第三方库所用的支持库版本比较麻烦，如果用的库很多的话工作量很大。这个时候我们可以考虑强制让所有模块都用相同的支持库版本。
在app build.gradle中添加：
configurations.all{
resolutionStrategy.eachDependency{ DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '26.1.0'
}
}
}
}
其中，27.1.1就是你要使用的支持库版本号，你可以根据需要改成其它的。附上build.gradle 文件
apply plugin: 'com.android.library'
apply plugin: 'com.jakewharton.butterknife'
android {
compileSdkVersion 27
defaultConfig {
minSdkVersion 21
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
//强制让所有模块都用相同的支持库版本
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '27.1.1'
}
}
}
}
}
