为什么Gradle总是说:
"所有的com.android.support库必须使用完全相同的版本规范(混合版本可能会导致运行时崩溃)。发现版本为27.1.1、27.1.0。例如:
com.android.support:animated-vector-drawable:27.1.1
和com.android.support:exifinterface:27.1.0
"
那么27.1.0在哪里?
build.gradle:
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
testImplementation 'junit:junit:4.12'
implementation 'com.android.support:appcompat-v7:27.1.1'
