Question

当我处理GCM时，我在“”类上遇到了一些错误。错误出现在这里：

onHandleIntent(Intent intent)

“无法覆盖GCMBaseIntentService的最终方法”

handleRegistration

“类型中的方法handleRegistration（Context，Intent） GCMBaseIntentService不适用于参数（Intent）“

handleMessage

“方法handleMessage（Intent）未定义类型 GCMIntenetService“

public final void onHandleIntent(Intent intent) {
            try {
                String action = intent.getAction();
                if (action.equals("com.google.android.c2dm.intent.REGISTRATION")) {
                    handleRegistration(intent);
                } else if (action.equals("com.google.android.c2dm.intent.RECEIVE")) {
                    handleMessage(intent);
                }
            } finally {
                synchronized (LOCK) {
                    sWakeLock.release();
                }
            }
        }

您不应该覆盖GCMBaseIntentService的最终方法。你只需要ovveride这个基类的回调方法。这是一个例子：

public class GCMIntentService extends GCMBaseIntentService {

    private static final String GCM_SENDER_ID = "your_sender_id";

    public GCMIntentService() {
        super();
    }

    @Override
    protected void onRegistered(Context context, String gcmDeviceToken) {
        // remember and save somewhere "gcmDeviceToken"
    }

    @Override
    protected void onUnregistered(Context context, String s) {
        // Push unregistered processing
    }

    @Override
    protected void onError(Context context, String errorId) {
        // push error processing
    }

    @Override
    protected void onMessage(Context context, Intent intent) {
        // process Push message
    }

    public static void registerInGCMService(Context context) {
        if (!checkIsGCMServiceAvailable(context)) {
            return;
        }
        final String regId = GCMRegistrar.getRegistrationId(context);
        if (regId.equals("")) {
            try {
                GCMRegistrar.register(context, GCM_SENDER_ID);
            } catch (Exception ex) {
            }
        } else {
            // Already registered
        }
    }

    public static boolean checkIsGCMServiceAvailable(Context context) {
        try {
            GCMRegistrar.checkDevice(context);
            GCMRegistrar.checkManifest(context);
            return true;
        } catch (Throwable th) {
            return false;
        }
    }

}

更新：请注意 - 您应该使用自己的值更改 GCM_SENDER_ID 常量，它应该是数值，例如“1234567890123”

Answer 2

@Override
    protected void onRegistered(Context context, String registrationId) {
        Log.i(TAG, "Device registered: regId = " + registrationId);
        GCMRegistrar.setRegisteredOnServer(context, true);
    }

    @Override
    protected void onMessage(Context context, Intent intent) {
        Log.i(TAG, "Received message");
        Log.i(TAG, "EXTRAS" + intent.getExtras());
        String message = getString(R.string.gcm_message);
        // notifies user about message

    }

    @Override
    protected void onUnregistered(Context context, String registrationId) {
        Log.i(TAG, "Device unregistered");
        if (GCMRegistrar.isRegisteredOnServer(context)) {
                Log.i(TAG, "unregistering device (regId = " + regId + ")");
        GCMRegistrar.setRegisteredOnServer(context, false);
        } else {
            // This callback results from the call to unregister made on
            // ServerUtilities when the registration to the server failed.
            Log.i(TAG, "Ignoring unregister callback");
        }
    }
