java - 如何在我自己的 Android 应用程序中添加推送通知

Question

我在 Android 中根据本教程开发了一个推送通知应用程序:push notification in android app .运行应用程序时会显示注册按钮。当我点击注册按钮时，当注册成功时，我的设备上会显示一条通知。

如何将它包含在我自己的应用程序中？我的应用程序有一个 xml 解析示例应用程序。在这里，当添加任何新项目时，我希望在设备上显示(显示新订单)通知消息。它在这里自动生成。

我正在发布 Google Cloud Messaging 的演示应用程序.

确保您创建的演示应用程序的 API 级别等于或高于 Android OS 2.2 with Google API

用户必须至少登录一个 Google 帐户才能使用此服务。

首先你必须添加GCM library .

比在我命名为 GCMIntentService 的类上创建，它扩展了 GCMBaseIntentService如下:

package com.example.gcmdemo;

import android.content.Context;
import android.content.Intent;
import android.util.Log;

import com.google.android.gcm.GCMBaseIntentService;
import com.google.android.gcm.GCMConstants;

public class GCMIntentService extends GCMBaseIntentService {

     private static final String TAG = "Push Notification Demo GCMIntentService";

    @Override
    protected void onError(Context context, String errorId) {

        if(GCMConstants.ERROR_ACCOUNT_MISSING.equalsIgnoreCase(errorId)) {
            Log.v(TAG, "Error Account Missing");
        } else if(GCMConstants.ERROR_AUTHENTICATION_FAILED.equalsIgnoreCase(errorId)) {
            Log.v(TAG, "Error Authentication Failed");
        } else if(GCMConstants.ERROR_INVALID_PARAMETERS.equalsIgnoreCase(errorId)) {
            Log.v(TAG, "Error Invalid Parameters");
        } else if(GCMConstants.ERROR_INVALID_SENDER.equalsIgnoreCase(errorId)) {
            Log.v(TAG, "Error Invalid Sender");
        } else if(GCMConstants.ERROR_PHONE_REGISTRATION_ERROR.equalsIgnoreCase(errorId)) {
            Log.v(TAG, "Error Phone Registration Error");
        } else if(GCMConstants.ERROR_SERVICE_NOT_AVAILABLE.equalsIgnoreCase(errorId)) {
            Log.v(TAG, "Error Service Not Available");
        } 
    }

    @Override
    protected void onMessage(Context context, Intent intent) {

        // App Server Sends message as key value pairs 
        String value1 = intent.getStringExtra("key1");
        String value2 = intent.getStringExtra("key2");

        Log.v(TAG, "key1: "+value1 );
        Log.v(TAG, "key2: "+value2 );
    }

    @Override
    protected void onRegistered(Context context, String regId) {

        Log.v(TAG, "Successfull Registration : "+regId);
    }

    @Override
    protected void onUnregistered(Context context, String regId) {

        Log.v(TAG, "Successfully Unregistred : "+regId);
    }

    @Override
    protected String[] getSenderIds(Context context) {
        return super.getSenderIds(context);
    }

    @Override
    protected void onDeletedMessages(Context context, int total) {
        super.onDeletedMessages(context, total);
    }

    @Override
    protected boolean onRecoverableError(Context context, String errorId) {
        return super.onRecoverableError(context, errorId);
    }
}

以下是在以下演示 Activity 中检查注册的方法:

package com.example.gcmdemo;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;

import com.google.android.gcm.GCMRegistrar;

public class MainActivity extends Activity {

    private static final String TAG = "Push Notification Demo Activity";
    private static final String SENDER_ID = "1069713227710";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        GCMRegistrar.checkDevice(this);
        GCMRegistrar.checkManifest(this);
        final String regId = GCMRegistrar.getRegistrationId(this);
        if (regId.equals("")) {
          GCMRegistrar.register(this, SENDER_ID);
        } else {
          Log.v(TAG, "Already registered : "+regId);
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

最后是演示 list :

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.gcmdemo"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="8" />

    <permission
        android:name="com.example.gcmdemo.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />

    <uses-permission android:name="com.example.gcmdemo.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="com.example.gcmdemo" />
            </intent-filter>
        </receiver>

        <service android:name=".GCMIntentService" />
    </application>

</manifest>

您还需要third party server side script as specified here .
