Gradle 依赖性问题 android

Question

我注意到 io.reactive 和 estimote 的 sdk 之间存在冲突，但我似乎无法弄清楚如何解决它。老实说，我只是通过删除 estimote 依赖项然后删除两个 reactivex 依赖项并找到项目功能来注意到冲突。我尝试排除公共库，但似乎没有任何效果。这是我所有的东西：

我不太确定如何解释那里的最后一部分 - 所以如果我的问题被发现，我很想知道如何找到它以供将来参考！谢谢！

Answer 1

 // Enabling multidex support.
    multiDexEnabled true

在您的 defaultConfig 并添加这个

 dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

https://developer.android.com/tools/building/multidex.html

https://developer.android.com/reference/android/support/multidex/MultiDexApplication.html

Answer 2

简单的不推荐修复是：

在您应用的 build.gradle 中：

android {
   ...
   defaultConfig {
       ...
       // Enabling multidex support.
       multiDexEnabled true
   }
...
}

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

在你的AndroidManifest.xml中：

<application
    ...
    android:name="android.support.multidex.MultiDexApplication">
    ...
</application>

原因：

Android application (APK) files contain executable bytecode files in the form of Dalvik Executable (DEX) files, which contain the compiled code used to run your app. The Dalvik Executable specification limits the total number of methods that can be referenced within a single DEX file to 65,536, including Android framework methods, library methods, and methods in your own code. Getting past this limit requires that you configure your app build process to generate more than one DEX file, known as a multidex configuration.

此处所有详细信息：Building Apps with Over 65k Methods。

虽然给出的答案将是解决您当前问题的快速方法，Android 建议您不要使用它，或者至少建议您尽可能避免使用它。

减少您的 dexcount

尽量避免依赖大型开源项目，除非你真的需要它们。如果您无法避免这些，请巧妙地使用它们。 GooglePlayServices 等一些图书馆为您提供使用其 API 的一个子集以防止此类问题。

例如，您有：

com.google.android.gms:play-services:6.+ // The ENTIRE play-services library

您真的需要整个播放服务库吗？该库很大，Google 为您提供了只使用所需组件的方法，假设您想使用 Google 帐户登录，您可以使用以下方法：

com.google.android.gms:play-services-identity:X.+ // Google Account Login only
com.google.android.gms:play-services-analytics:X.+ // Google Analytics
com.google.android.gms:play-services-maps:X.+ // Google Maps...
// ... and so on.

有关播放服务的个人 API 列表，请参阅 Setting Up Google Play Services

跟踪您的 dexcount

有几个库可以帮助您跟踪您的 dexcount，以防止您达到限制。一个例子：

Dexcount Gradle Plugin

此库将跟踪您的 dexcount 并在您构建时报告它，例如：

> ./gradlew assembleDebug

...buildspam...
:app:compileDebugSources
:app:preDexDebug UP-TO-DATE
:app:dexDebug
:app:packageDebug
:app:zipalignDebug
:app:assembleDebug
Total methods in MyApp-debug-5.3.14.apk: 56538
