在Eclipse中如何進行Android應用的推送通知設置

在Eclipse中進行Android應用的推送通知設置，需要使用Google Cloud Messaging (GCM) 服務。以下是設置步驟：

1. 首先，需要在Google Cloud Console中創建一個項目并啟用GCM服務。然后，獲取項目的API密鑰（Server Key）。

2. 在Eclipse中，打開你的Android項目。

3. 添加GCM依賴項到項目的build.gradle文件中：

dependencies {
    implementation 'com.google.android.gms:play-services-gcm:17.0.0'
}

4. 在AndroidManifest.xml文件中，添加必要的權限和GCM服務聲明：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application ...>
    ...
    <service android:name=".MyGcmListenerService" android:exported="false">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </service>
    <receiver android:name=".MyGcmBroadcastReceiver">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </receiver>
</application>

5. 創建一個新的類MyGcmListenerService，繼承自GcmListenerService，并實現onMessageReceived方法來處理接收到的消息：

import com.google.android.gms.gcm.GcmListenerService;
import android.os.Bundle;
public class MyGcmListenerService extends GcmListenerService {
    @Override
    public void onMessageReceived(String from, Bundle data) {
        // 處理接收到的消息
    }
}

6. 創建一個新的類MyGcmBroadcastReceiver，繼承自BroadcastReceiver，并實現onReceive方法來處理注冊和消息接收事件：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class MyGcmBroadcastReceiver extends BroadcastReceiver {
    private static final String TAG = "MyGcmBroadcastReceiver";
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals("com.google.android.c2dm.intent.REGISTRATION")) {
            // 處理設備注冊事件
        } else if (action.equals("com.google.android.c2dm.intent.RECEIVE")) {
            // 處理接收到的消息事件
        }
    }
}

7. 在MainActivity或其他適當的地方，初始化GCM客戶端并請求注冊ID：

import com.google.android.gms.gcm.GoogleCloudMessaging;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
    private GoogleCloudMessaging gcm;
    private String regid;
    private static final String PROJECT_NUMBER = "YOUR_PROJECT_NUMBER"; // 替換為你的項目編號
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button registerButton = findViewById(R.id.register_button);
        registerButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                registerInBackground();
            }
        });
    }
    private void registerInBackground() {
        new AsyncTask<Void, Void, String>() {
            @Override
            protected String doInBackground(Void... params) {
                String msg = "";
                try {
                    if (gcm == null) {
                        gcm = GoogleCloudMessaging.getInstance(getApplicationContext());
                    }
                    regid = gcm.register(PROJECT_NUMBER);
                    msg = "Device registered, registration ID=" + regid;
                    // You should send the registration ID to your server over HTTP, so it can use GCM/HTTP or CCS to send messages to your app.
                    sendRegistrationIdToBackend();
                    // Persist the registration ID - no need to register again.
                    storeRegistrationId(context, regid);
                } catch (IOException ex) {
                    msg = "Error :" + ex.getMessage();
                }
                return msg;
            }
            @Override
            protected void onPostExecute(String msg) {
                Toast.makeText(MainActivity.this, msg, Toast.LENGTH_LONG).show();
            }
        }.execute(null, null, null);
    }
}

8. 最后，確保你的服務器能夠處理來自GCM的推送通知請求，并將它們發送到相應的設備。
