【问题标题】：android app crashes when adding firebase ML vision dependencies with firebase database dependenciesandroid 应用程序在添加带有 firebase 数据库依赖项的 firebase ML 视觉依赖项时崩溃
【发布时间】：2018-06-26 20:47:14
【问题描述】：

我有一个使用 firebase 数据库、auth 和其他依赖项的项目，但是每当我尝试添加 firebase ml vision 或 google play service vision 依赖项时，尽管 gradle 构建成功，但应用程序崩溃了。

编辑：这就是 logcat 的样子

【问题讨论】：

  • 崩溃的错误/堆栈跟踪是什么样的？
  • 如果你的意思是 logcat 它仍然是空的，因为应用程序在启动之前崩溃了。另外请看一下我上传的 build.gradle 文件图像，我认为问题是由于依赖项之间的版本不匹配造成的。
  • 请不要将代码或错误消息作为图像发布，但请将它们包含在您的答案中。您是否尝试解决版本不匹配？您是否尝试过stackoverflow.com/questions/29568985/… 中描述的方法来获取日志记录？
  • 这就是 logcat 的帮助。现在也请看一下
  • 请正确格式化您的堆栈跟踪，然后尝试在 stackoverflow 上搜索错误。这看起来像是一个常见问题（鉴于我可以通过当前格式发现）

【解决方案1】：

我发现您的项目中有 firebase，您应该使用基于 on this link 的最新版本，例如：

    implementation 'com.crashlytics.sdk.android:crashlytics:2.9.4'
    implementation 'com.google.firebase:firebase-core:16.0.1'
    implementation 'com.google.firebase:firebase-ads:15.0.1'
    implementation 'com.google.firebase:firebase-analytics:16.0.1'
    implementation 'com.google.firebase:firebase-appindexing:16.0.1'
    implementation 'com.google.firebase:firebase-auth:16.0.2'
    implementation 'com.google.firebase:firebase-firestore:17.0.2'
    implementation 'com.google.firebase:firebase-functions:16.0.1'
    implementation 'com.google.firebase:firebase-messaging:17.0.0'
    implementation 'com.google.firebase:firebase-storage:16.0.1'
    implementation 'com.google.firebase:firebase-crash:16.0.1'
    implementation 'com.google.firebase:firebase-invites:16.0.1'
    implementation 'com.google.firebase:firebase-perf:16.0.0'
    implementation 'com.google.firebase:firebase-database:16.0.1'
    implementation 'com.google.firebase:firebase-config:16.0.0'

选择你想要的，同时确保在你的应用程序 gradle 中也更新了谷歌服务：(check this link)

classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.1'

    【解决方案2】：

    在清理和构建项目后，您的 firebase 依赖项必须具有相同的版本
