无法解析com.google.android.gcm.GCMBaseIntentService; Android工作室 [英] Cannot resolve com.google.android.gcm.GCMBaseIntentService; Android studio

问题描述

$ b

1. 教程实施GCM客户端，有链接下载演示的完整源代码。


2. 已下载作为参考，在build.gradle中添加了google_play_service库。


3. 做了一些推荐的更改，例如SENDER_ID，SERVER_URL，.. etc。 >使用gradle同步项目并发生此错误。
   

我如何解决问题！

1. 经过很多google之后，我发现这个类不在google_play_service库中，但它在gcm.jar中，现在不推荐使用。
   我不知道为什么google给出了旧代码的链接，并解释了文档中的最新代码。
   
2. 然后我包含gcm.jar
   
3. 错误消失了，得到了推送通知：）

希望这会对遇到麻烦的人有所帮助！

我的老问题

我是android studio的新手。我不明白build.gradle。今天我按照 https://developer.android提供的说明执行gcm-demo-client。 com / google / gcm / client.html
但是，当我从建议的导入它时

  / home / shani / Desktop / gcm-76908409d9d5 / samples / gcm -demo-client1 / app / src / main / java / com / google / android / gcm / demo / app / GCMIntentService.java：28：error：can not find symbol 
 import com.google.android.gcm.GCMBaseIntentService ; 
 ^ 
 symbol：class GCMBaseIntentService 
 location：package com.google.android.gcm 
  

还有其他25个错误。在Google上进行了一些搜索之后，我发现它是因为我没有在build.gradle中添加google play服务库。

然后我添加了库：
下面是我的build.gradle文件

  apply plugin：'com.android.application'
 
 android {
 compileSdkVersion 21 
 buildToolsVersion21.1.2
 
 defaultConfig {
 applicationIdcom.google.android.gcm.demo.app
 minSdkVersion 8 
 targetSdkVersion 16 
} 
 
 buildTypes {
 release {
 minifyEnabled false 
 proguardFiles getDefaultProguardFile（'proguard-android.txt'），'proguard -rules.txt'
} 
依赖关系{
 compilecom.google.android.gms：play-services：3.1。+
} 
} 
 
  

现在，当我点击同步链接时，我获得了Build Success。但是，当我尝试在真正的设备上运行上面的错误来。我不知道我做错了什么。请给我解决方案，我真的花了两天实施gcm演示应用程序。 如果您使用最新版本的 7.0.0 版本，则会发生这种情况。由于方法计数（65536）的上限是如何的，他们将Google Play服务进一步细分为6.5。

无论如何，

  compile'c​​om.google.android.gms：play-services-base：6.5.87'
  

这适用于指南提及的 GCM 类。

但它也可以通过更新到最新的

  compile'c​​om.google.android.gms： play-services-gcm：7.0.0'
  

Edit: I solved this problem:) Cause of this error :

1. In the tutorial Implementing GCM Client , there was link to download full source code for demo.
2. Downloaded for reference , added google_play_service library in build.gradle.
3. Did some recommended changes like SENDER_ID,SERVER_URL,.. etc
4. Synch the project with gradle and got this error.

How I solved!

1. After lot of google I found that this class is not in google_play_service library but it is in gcm.jar which is deprecated now. I dont know why google has given link to old code and explained latest code in the document.
2. Then I include the gcm.jar
3. And the error gone, got push notification:)

Hope this will help to someone who got in this trouble!

My Old Question

I am new to android studio. I dont understand build.gradle. Today I was implementing gcm-demo-client following instructions given here https://developer.android.com/google/gcm/client.html But when I import it from suggested open source code I got below errors.

/home/shani/Desktop/gcm-76908409d9d5/samples/gcm-demo-client1/app/src/main/java/com/google/android/gcm/demo/app/GCMIntentService.java:28: error: cannot find symbol
import com.google.android.gcm.GCMBaseIntentService;
                             ^
  symbol:   class GCMBaseIntentService
  location: package com.google.android.gcm

also there are other 25 errors. After some search on Google I found that it is because I had not added google play service library in build.gradle.

Then I added library: Below is my build.gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.google.android.gcm.demo.app"
        minSdkVersion 8
        targetSdkVersion 16
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
        dependencies {
            compile "com.google.android.gms:play-services:3.1.+"
        }
    }
}

Now when I click on sync now link I got Build Success. But when I try to run on real device above error comes. I dont know what I am doing wrong. Please give me the solution, I really spend two days implementing gcm demo app.

解决方案

This happens if you use the latest, 7.0.0 version. They sliced up the Google Play Services a bit further than in 6.5, due to how there is an upper limit to method count (65536).

Anyways,

compile 'com.google.android.gms:play-services-base:6.5.87'

This works with the GCM classes the guides mention.

But it also works by updating to the latest

compile 'com.google.android.gms:play-services-gcm:7.0.0'
