我的GCM客户端能够在所有版本上注册，但消息是在4. strong版本以上的 android上接收的，而不是在Android 2.3.6 上。我已经做了很多改变，但我无法解决这个问题请帮助我，提前谢谢。

Answer 1

如果您使用的是产品口味，可能会遇到与我发现的问题相同的问题。

我发现当使用不同的applicationId的flavor时，那么你的包在AndroidManifest文件中的权限和类别是不正确的。这对于Android 5.x无关紧要，但对于Android 2.3会导致广播接收器永远不会被调用。

我找到的解决方案是使用gradle＆＃39; placeholder support。使用 $ {applicationId} ，解决了所有Android版本的问题。

<强>的build.gradle ：

productFlavors {
    prod {
        applicationId 'com.democlientapp'
    }
    dev {
        applicationId 'com.democlientapp.dev'
    }
}

<强>的AndroidManifest.xml ：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.democlientapp"
    android:versionCode="1"

    <permission android:name="${applicationId}.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />

Answer 2

对于sdk版本4或更高版本

使用GCM的最新依赖项/库

 compile "com.google.android.gms:play-services-gcm:10.2.0"

在依赖的build.gradle文件中。并添加build.gragle级别文件

classpath 'com.google.gms:google-services:3.0.0'

它适用于更为严格的版本。

在Android 2.3.6 v上没有收到GCM消息，但在android 4.X v上工作正常
