FCM实现手机
1 下载Androidstudio 3.2 版本，之后新建一个项目
2 创建完项目之后查找文件AndroidMainifest.xml
3 访问网站注册一个自己的firebase的账户 https://console.firebase.google.com
5 进入自己的项目当中，之后添加自己的app，可以是Android的也可以是iOS，在这里我们以Android为例子
6 选择Android的APP之后会让你注册这个APP
7 点击Register app之后会生成下面的画面，之后点击下载.json文件放到指定的目录下即可
8 按照指定的操作即可，把下面的代码拷贝到指定的文件下，之后点击同步
9 同步是否成功看你是否出错
同步的时候可能会出现下面的错误
10 在这一步可能会很慢，不用管他，直接点击Skip this step 即可
11 之后会生成一个app：sdf
12 到此firebase的服务器配置完了
13 配置前台，找到文件app下的build.gradle下面追加下面的两行代码，如下图所示
implementation \'com.google.firebase:firebase-messaging:17.3.4\' implementation \'com.firebase:firebase-jobdispatcher:0.8.5\'
14 在下面的路径下追加三个类，并修改AndroidMainifest.xml文件
MyJobService
package com.example.peiqiang.fcm_test;
import android.util.Log;
import com.firebase.jobdispatcher.JobParameters;
import com.firebase.jobdispatcher.JobService;
public class MyJobService extends JobService {
private static final String TAG = "MyJobService";
@Override
public boolean onStartJob(JobParameters jobParameters) {
Log.d(TAG, "Performing long running task in scheduled job");
// TODO(developer): add long running task here.
return false;
}
@Override
public boolean onStopJob(JobParameters jobParameters) {
return false;
}
}

activity_main.xml文件是设计你的app在手机上的具体显示
配置完之后可能会出现一些图片找不到的情况，这样你就要去下面的网址找到对应的图片，放到你自己的工程下面，路径参照网址
https://github.com/firebase/quickstart-android/tree/master/messaging/app/src/main/res
16 编译如果没有错误的话，到目前为止就算是OK了
17 启动你的虚拟机
在这遇到的坑有，haxm安装不上
Android studio的虚拟手机启动不起来，window10系统需要安装haxm的文件，如果你没有安装的话再window10系统启动不起来的，window7系统好像可以直接启动，可以尝试着看一下，如果不好用的话在寻找haxm文件
haxm文件自己去C盘下搜索所有的文件就可以找到。当你安装的时候报下图错误的时候，可以上网自己找一下，有相关的解答。解决的办法就是取你的BIOS里面设置一下。Window10设置完之后还是启动不了的话，就去找你的系统是否安装
过window10 自带的虚拟机，如果安装过，OK问题就在这了。去查找你的控制面板里面，找到下图的地方，把Hyper-V给去掉之后再重新安装haxm文件，应该就不会出现这种问题了
18 启动你的虚拟机之后会让你选择你的手机虚拟机的版本问题
19 运行起来之后你的虚拟手机上会出现你自己创建的app
20 到此为止，你的前台和后台配置完成了接下来就是发送消息
发送消息有两种模式，一种是用postman来发送，一种是用firebase的服务器来发送
postman来发送
上网自己下载一个postman的一个软件打开之后如下图
解释说明
1. 网址URL是固定的，调用你的firebase服务器 【https://fcm.googleapis.com/fcm/send】
2. 传送方式是POST形式
3. 选择你传送出去的参数形式
4.具体的数据。
{
"to" : "token",
"notification" : {
"body" : "push body test aadfadfadsfasdfa!",
"title" : "pusqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq"
}
}
5.点击send之后就会把消息发送到你手机设备上面
在运行的时候遇到的一些盲点，有经验的人知道，对于像我这样的菜鸟来说，就是一个非常大的坑，坑了我三天，还是在有经验的人那里学到的测试的方法
在目前我们的代码程度上，如果你的画面是下面的画面的话，之后你在点击send进行发信的话，恭喜你，你也与我一样。在下面的画面上进行推送是不成功的，你手机不会收到消息的
只有把我们的app隐藏，或者是在后台执行，这种情况下是可以推送到我们的手机上的，如果想要在app在画面上显示之后进行推送的话，就要再写代码，代码怎么可以自己上网查，我还没做到这一步
再有一点就是postman他有的时候会延迟，不会及时的送到消息，一般的情况下会及时的推送到你手机上，但是有的情况下是不会即使的推送到你手机上面的，要多等一会，这个需要注意
测试时候的小窍门，就是把你的app给卸载之后在启动Androidstudio，来回往复
token取得方法，在你运行的时候会把你安装的在虚拟手机上面的token号直接打在Logcat里面，
请注意，只有每次app安装的时候token才会打到logcat里面，如果第一次安装了，没有卸载的情况下，执行这个重启app或者重启虚拟机都打不出来token的
用firebase服务器来发送消息，具体参照下图
21 虚拟机弄好之后就要用真机器来试验你做的app有没有问题了，这里讲一下用真机器来调试你的APP
Android studio工具里面点击下图的标识之后会出现增加Android APP的界面
手机打开你的开发者选项，如果不知道在哪的话可以在网上搜一下，打开USB调试即可，有的手机即使打开了USB调试了但是在运行你的Android studio的时候是会报错的，这样的话你就要换一台手机了
用数据线链接你的手机和电脑之后就可以按照下图的方式点击运行APP就会安装在你的手机上面，如果是debug的话，是可以打断点的
