我正在尝试通过 GCM 将推送消息传递到我在调试模式下本地连接到桌面的 Android 设备。我可以在 GCM 上注册并取回注册 ID。但是,当我从服务器向 GCM 发送消息时,它永远不会到达我的设备。任何想法这里缺少什么?
这是我用来向 GCM 发送消息的 C# 代码:
wc.Headers.Add("Authorization", "key=" + senderAuthToken);
var nameValues = new NameValueCollection
{
{"registration_id", registrationId},
{"collapse_key", Guid.NewGuid().ToString()},
{"data.payload", HttpUtility.UrlEncode(message)}
};
var resp = wc.UploadValues("https://android.googleapis.com/gcm/send", nameValues);
var respMessage = Encoding.Default.GetString(resp);
这是我从 GCM 得到的回复:
id=0:1345244000449737%276b04adef6fbb69
所以看起来消息正在验证并在 GCM 中排队。
这是我的 AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="fiserv.mobile.poc"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="15" />
<permission android:name="fiserv.mobile.poc.permission.C2D_MESSAGE"
android:protectionLevel="signature"/>
<uses-permission android:name="fiserv.mobile.poc.permission.C2D_MESSAGE" />
<!-- App receives GCM messages. -->
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<!-- GCM connects to Google Services. -->
<uses-permission android:name="android.permission.INTERNET" />
<!-- GCM requires a Google account. -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<!-- Keeps the processor from sleeping when a message is received. -->
<uses-permission android:name="android.permission.WAKE_LOCK" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<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="fiserv.mobile.poc" />
</intent-filter>
</receiver>
<service android:name=".GCMIntentService" />
</application>
这是我的 GCMIntentService.java 服务:
package fiserv.mobile.poc;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import com.google.android.gcm.GCMBaseIntentService;
public class GCMIntentService extends GCMBaseIntentService {
@Override
protected void onError(Context arg0, String arg1) {
Log.e("Registration", "Got an error!");
Log.e("Registration", arg0.toString() + arg1.toString());
}
@Override
protected void onMessage(Context arg0, Intent arg1) {
Log.i("Registration", "Got a message!");
}
@Override
protected void onRegistered(Context arg0, String arg1) {
Log.i("Registration", "Just registered!");
Log.i("Registration", arg0.toString() + arg1.toString());
}
@Override
protected void onUnregistered(Context arg0, String arg1) {
}
}
最后是我的 MainActivity.java:
package fiserv.mobile.poc;
import fiserv.mobile.poc.R;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import com.google.android.gcm.GCMRegistrar;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RegisterWithGCM();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
private void RegisterWithGCM()
{
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
GCMRegistrar.register(this, SENDER_ID);
} else {
Log.v("Registration", "Already registered, regId: " + regId);
}
}
String SENDER_ID = "158778556981";
}
当我向 GCM 注册时,我可以看到日志语句,但onMessage
无论我向 GCM 发送多少消息,我都没有点击或看到日志语句“收到消息!”。我已验证我正在使用与我在 Android 应用程序中使用的“发件人 ID”匹配的服务密钥。
任何想法为什么没有传递消息?
