Android - FirebaseApp / Firebase - 初始化不开始 [英] Android - FirebaseApp / Firebase-Initialization is not starting

问题描述

我想在我的Android应用程序中实施Firebase消息传递插件。
我从github的quickstart-android-master / messaging例子开始： https://github.com/firebase/quickstart-android/tree/master/messaging

这适用于我！
日志输出：

  D / FirebaseApp：com.google.firebase.auth.FirebaseAuth未关联。跳过初始化。 
 D / FirebaseApp：已初始化的类com.google.firebase.iid.FirebaseInstanceId。 
 D / FirebaseApp：com.google.firebase.crash.FirebaseCrash未链接。跳过初始化
 D / FirebaseApp：已初始化的类com.google.android.gms.measurement.AppMeasurement。 
 I / FirebaseInitProvider：FirebaseApp初始化成功
  

希望将插件
com.google.firebase：firebase-messaging：9.0.2实现到我的应用中，
FirebaseApp不会被初始化！所以FirebaseApp插件没有启动！ - 没有收到日志或令牌！

我也在app目录下添加了apply插件build.gradle文件： / p>

  apply plugin：'com.android.application'
 
 android {
 //。 .. 
} 
 
依赖关系{
 // ... 
编译'com.google.firebase：firebase-messaging：9.0.2'
 } 
 
 //在底部添加
 apply plugin：'com.google.gms.google-services'
  

和google-services插件build.gradle在root目录下：

  buildscript {
 // ... 
依赖项{
 // ... 
 classpath'com.google.gms：google-services：3.0.0'

解决方案
问题是Android的Manifest Merger。 
如果我使用 
 
 
  xmlns：tools =http://schemas.android.com/tools
  
和
 <$ c在清单的Application Tag中，$ c> tools：node =replace
  
，FirebaseApp会不会初始化！
 
 
 
摘要：如果在 tools：node 中使用替换 attr，
会将您的低优先级声明替换为带注释的声明（请参阅更多 here ）。您应该使用合并或合并属性。
 
 
 
所以我确实做了：
 
 
 
这是行不通的： 
 
 
 < application 
 android ：name =xxx
 android：icon =@ mipmap / ic_launcher
 android：label =@ string / application_name
 android：theme =@ style / Theme.TemplateStyle 
 tools：node =replace> 
  
这个工作： 
 
 
 
 android：label =@ string / application_name
 android：theme =@ style / Theme.TemplateStyle> 
 <！ -  tools：node =replace - > 
  
 
I want to implement the Firebase-Messaging plugin into my Android-App.
I've started with the "quickstart-android-master/messaging"-example from github: https://github.com/firebase/quickstart-android/tree/master/messaging


This works for me!
Log-Output:
D/FirebaseApp﹕ com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization.
D/FirebaseApp﹕ Initialized class com.google.firebase.iid.FirebaseInstanceId.
D/FirebaseApp﹕ com.google.firebase.crash.FirebaseCrash is not linked. Skipping initialization
D/FirebaseApp﹕ Initialized class com.google.android.gms.measurement.AppMeasurement.
I/FirebaseInitProvider﹕ FirebaseApp initialization successful



  
But if I want to implement the Plugin
  "com.google.firebase:firebase-messaging:9.0.2" into my app, the
  FirebaseApp isn't initialized! So the FirebaseApp plugin isn't starting! - No Log or token received!
I've also added apply plugin to build.gradle file in "app"-directory:
    apply plugin: 'com.android.application'

android {
  // ...
}

dependencies {
  // ...
  compile 'com.google.firebase:firebase-messaging:9.0.2'
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'
And the google-services plugin to build.gradle in the "root" directory:
buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:3.0.0'
    }
}



  
Problems could be:



AndroidAnnotations, Proguard, Product flavors... 

解决方案
The problem is the "Manifest Merger" of Android.
If I use the 
xmlns:tools="http://schemas.android.com/tools"
and 
tools:node="replace"
in the Application Tag of the Manifest, the FirebaseApp will not be initialized!

Summary:
if you use replace attr on tools:node it will replace your lower priority declaration with the annotated one (see more here). You should use merge or merge only attributes instead.

So what I've exactly done:

This doesn't work:
<application
            android:name="xxx"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/application_name"
            android:theme="@style/Theme.TemplateStyle"
            tools:node="replace">
this works:
<application
            android:name="xxx"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/application_name"
            android:theme="@style/Theme.TemplateStyle">
            <!-- tools:node="replace"-->
