是否可以从adb shell/am命令行模拟GCM接收？我遇到一个错误

Question

我正在尝试使用 adb 和命令行模拟设备正在接收 GCM 推送消息。我尝试使用此命令来广播 GCM 意图：

adb shell am broadcast -c com.myapp -a com.google.android.c2dm.intent.RECEIVE -e data "SomeData"

这将触发一个“权限拒绝”日志行:

09-19 12:23:34.820      725-787/? W/BroadcastQueue﹕ Permission Denial: broadcasting Intent { act=com.google.android.c2dm.intent.RECEIVE cat=[com.myapp] flg=0x10 (has extras) } from null (pid=21244, uid=2000) requires com.google.android.c2dm.permission.SEND due to receiver com.myapp/com.google.android.gcm.GCMBroadcastReceiver

我的清单的相关部分：

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<application>
<receiver
    android:name="com.google.android.gcm.GCMBroadcastReceiver"
    android:permission="com.google.android.c2dm.permission.SEND" >
    <intent-filter>
        <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
        <category android:name="com.myapp" />
    </intent-filter>
</receiver>
</application>

有什么想法吗？

编辑/澄清：推送/GCM接收生产中的作品。我正在寻找一种更简单的方法来测试更改。

Answer 1

我建议使用命令行curl，因为发送GCM推送就像调用一些REST API一样简单。请参见下面的示例shell脚本：

#!/bin/bash

REGISTRATION_ID=YOUR_GCM_REGISTRATION_ID

SERVER_KEY=YOUR_SERVER_KEY_FROM_GOOGLE_API_CONSOLE

curl --header "Authorization: key=$SERVER_KEY" --header  Content-Type:"application/json"  https://android.googleapis.com/gcm/send  -d  "{ \"data\" : {\"foo\": \"bar\"}, \"registration_ids\":[\"$REGISTRATION_ID\"]  }"

Answer 2

比临时编辑 AndroidManifest 更好.xml删除权限检查，并记住稍后恢复它，您可以在调试版本中自动禁用权限检查。

为此，请通过清单合并占位符设置该属性:

<receiver
  android:name="com.google.android.gcm.GCMBroadcastReceiver"
  android:permission="${gcmPermissionRequired}">

然后在< code>build.gradle中设置占位符:

buildTypes {
    debug {
        ...
        manifestPlaceholders = [gcmPermissionRequired: ""] // "" => let the GCM BroadcastReceiver accept Intents from 'adb shell am broadcast'
    }
    release {
        ...
        manifestPlaceholders = [gcmPermissionRequired: "com.google.android.c2dm.permission.SEND"]
    }
}

（注意：以前我使用debug

您需要删除接收者定义中的权限属性，如下所示：

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<application>
<receiver
    android:name="com.google.android.gcm.GCMBroadcastReceiver" >
    <intent-filter>
        <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
        <category android:name="com.myapp" />
    </intent-filter>
</receiver>
</application>
