WARNING: API 'variant.getPackageLibrary()' is obsolete and has been replaced with 'variant.getPackageLibraryProvider()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration-avoidance.
To determine what is calling variant.getPackageLibrary(), use -Pandroid.debug.obsoleteApi=true on the command line to display more information.
Affected Modules: Module-Name

额，参考下：https://github.com/novoda/bintray-release/issues/260

我工程是由于升级fabric 导致的.
这个问题应该是Kotlin 导致的

二

In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[17.1.
2]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

Dependency failing: com.google.firebase:firebase-messaging:17.6.0 -> com.google.firebase:firebase-iid@[17.1.2], but fire
base-iid version was 18.0.0.

The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
ifact with the issue.
-- Project 'app' depends onto com.google.firebase:firebase-config@17.0.0
-- Project 'app' depends onto com.google.firebase:firebase-iid@{strictly 18.0.0}
-- Project 'app' depends onto io.intercom.android:intercom-sdk@{strictly 5.3.0}
-- Project 'app' depends onto com.google.firebase:firebase-perf@{strictly 17.0.0}
-- Project 'app' depends onto com.google.firebase:firebase-perf@17.0.0
-- Project 'app' depends onto com.google.firebase:firebase-core@16.0.9
-- Project 'app' depends onto io.intercom.android:intercom-sdk@5.+
-- Project 'app' depends onto com.google.firebase:firebase-core@{strictly 16.0.9}
-- Project 'app' depends onto com.google.firebase:firebase-analytics@{strictly 16.5.0}
-- Project 'app' depends onto com.google.firebase:firebase-config@{strictly 17.0.0}
-- Project 'app' depends onto io.intercom.android:intercom-sdk-fcm@{strictly 5.3.0}
-- Project 'app' depends onto com.google.firebase:firebase-messaging@{strictly 17.6.0}
-- Project 'app' depends onto com.google.android.gms:play-services-measurement-api@{strictly 16.5.0}

For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b
uild.gradle file.

解决方法：
app module 下 build.gradle 下添加，目前我测试编译仍然失败，找不到下面这个库

com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true

参考：https://github.com/AzureAD/microsoft-authentication-library-for-android/issues/529

目前测试可用方法，添加：

googleServices.disableVersionCheck = true

参考https://github.com/google/play-services-plugins/issues/36

三

使用如下做一些特殊格式处理：

val agreement = Html.fromHtml()

报错如下：

解决方案：

if (Build.VERSION.SDK_INT >= 24) {
     Html.fromHtml(String, int) // for 24 api and more
 } else {
     Html.fromHtml(String) // or for older api
 }
