android - App SDK 从 27.0.2 迁移到 27.1.0 失败(崩溃)

Question

我今天早上刚刚用新的 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 启动时发生了崩溃。此 Activity 没有布局。在此 SDK 升级之前，它运行良好...

非常感谢大家的支持!

删除你的

buildToolsVersion 来自您的应用级 gradle 文件，以防您想要升级到 27.1.0。所以如果你把buildToolsVersion 27.0.2

或buildToolsVersion 27.0.3

可能存在冲突，因为 buildToolsVersion 27.1.0 尚未发布。

So, removing the buildToolsVersion x.x.x might do the trick !!

即使删除 buildToolsVersion 可能有效，我还是建议坚持使用 27.0.2，因为 27.1.0 会导致一些意外崩溃，并且有一些错误。其中之一是:-

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

甚至谷歌也宣布了它(在 GOOGLE ISSUE TRACKER 中)。所以，大家最好坚持使用 27.0.2，直到发布固定且稳定的版本。
