Question

当前在我的生产应用中，我注意到此错误：

java.lang.RuntimeException: 
  at android.app.ActivityThread.handleReceiver (ActivityThread.java:2648)
  at android.app.ActivityThread.access$1700 (ActivityThread.java:166)
  at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1359)
  at android.os.Handler.dispatchMessage (Handler.java:102)
  at android.os.Looper.loop (Looper.java:136)
  at android.app.ActivityThread.main (ActivityThread.java:5584)

  at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1084)
  at dalvik.system.NativeStart.main (Native Method)

，发现这是因为库冲突。我正在使用大约7，它们对于使应用程序正常运行是必不可少的。我做了./gradlew app:dependencies并看到一堆冲突（主要是android.support和google-services），现在必须使用exclude标签解决它们。

我的问题是如何正确设置正确的版本？我是强制所有库都移至某个库的最小版本，还是只是将它们都推至最新？

很抱歉出现noob问题，我对使用Android中的managin lib相当陌生。

编辑：更多堆栈跟踪

Caused by: java.lang.ClassNotFoundException: 
  at dalvik.system.BaseDexClassLoader.findClass (BaseDexClassLoader.java:56)
  at java.lang.ClassLoader.loadClass (ClassLoader.java:497)
  at java.lang.ClassLoader.loadClass (ClassLoader.java:457)
  at android.app.ActivityThread.handleReceiver (ActivityThread.java:2643)

还有一个similar error，但具有不同的堆栈跟踪。

Answer 1

由于minSdkVersion 18，您必须向com.android.support:multidex:1.0.3添加一个依赖项以获得适当的Dalvik VM支持。

Manifest.xml也需要引用Application类。

并回答实际问题；首先删除这一行：

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

然后将buildToolsVersion更新为28.0.3，并删除这些16.+版本号。

与+表示法相比，

静态版本号导致可重复的结果。与此类似，必须手动更新这些版本号-但至少有一个知道更新哪个版本号，以及在出现问题时必须将哪个版本号还原（值得付出努力）。

com.android.support:appcompat-v7:27.1.0也可以更新为28.0.0。

之后，Android Studio应该在红色下划线一些依赖项-提供可能需要排除或添加com.google.android.gms和com.android.support的线索。例如。 support-v4是排除的常见候选者-但必须以匹配的版本添加。
