Question

我今天早上使用新的SDK升级了我的Gradle：

    // https://developer.android.com/studio/build/multidex.html
    implementation 'com.android.support:multidex:1.0.3'

    // https://developer.android.com/topic/libraries/support-library/revisions.html
    implementation 'com.android.support:design:27.1.0'
    implementation 'com.android.support:customtabs:27.1.0'
    implementation 'com.android.support:gridlayout-v7:27.1.0'
    implementation 'com.android.support:support-v4:27.1.0'
    implementation 'com.android.support:support-v13:27.1.0'
    implementation 'com.android.support:appcompat-v7:27.1.0'
    implementation 'com.android.support:cardview-v7:27.1.0'
    implementation 'com.android.support:recyclerview-v7:27.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:exifinterface:27.1.0'

不幸的是，现在我的第一个Activity启动时出现了崩溃。此活动没有布局。它在SDK升级之前完美运行......

非常感谢你们的支持！

删除

如果您要升级到buildToolsVersion，请从应用级Gradle文件

27.1.0。所以，如果你把 buildToolsVersion 27.0.2

或buildToolsVersion 27.0.3

可能存在冲突原因buildToolsVersion 27.1.0 尚未发布。

所以，删除buildToolsVersion x.x.x可能会有所帮助!!

修改1

即使删除buildToolsVersion可能会有效，但我建议您坚持使用27.0.2，因为27.1.0导致某些意外崩溃并且有一些bugs。其中之一是： -

java.lang.ClassCastException: android.support.v7.widget.ActivityChooserView$InnerLayout cannot be cast to android.support.v7.widget.LinearLayoutCompat

即便谷歌也已宣布（在GOOGLE ISSUE TRACKER中）。所以，伙计们最好坚持27.0.2，直到发布固定版和稳定版。

App SDK从27.0.2迁移到27.1.0失败（崩溃）
