android - アプリを公開せずに GCM を使用する

Question

フレンド サークル内で使用したいアプリを開発していますが、Google Play でアプリを公開したくありません。アプリケーションをドラフト モードのままにして GCM サービスを使用できますか?

Answer 1

はい、アプリを公開しなくてもご利用いただけます。Nargis が言ったように、独自のサーバーを作成する必要があります。

ここに素晴らしいチュートリアルがあります。お役に立てば幸いです。

出来るよ..

static void register(final Context context, String name, String email, final String regId) {
//indented code
    Log.i(TAG, "registering device (regId = " + regId + ")");
    String serverUrl = SERVER_URL;
    Map<String, String> params = new HashMap<String, String>();
    params.put("regId", regId);
    params.put("name", name);
    params.put("email", email);

    long backoff = BACKOFF_MILLI_SECONDS + random.nextInt(1000);
    // Once GCM returns a registration id, we need to register on our server
    // As the server might be down, we will retry it a couple
    // times.
    for (int i = 1; i <= MAX_ATTEMPTS; i++) {
        Log.d(TAG, "Attempt #" + i + " to register");
        try {
            displayMessage(context, context.getString(
                    R.string.server_registering, i, MAX_ATTEMPTS));
            post(serverUrl, params);
            GCMRegistrar.setRegisteredOnServer(context, true);
            String message = context.getString(R.string.server_registered);
            CommonUtilities.displayMessage(context, message);
            return;
        } catch (IOException e) {
            // Here we are simplifying and retrying on any error; in a real
            // application, it should retry only on unrecoverable errors
            // (like HTTP error code 503).
            Log.e(TAG, "Failed to register on attempt " + i + ":" + e);
            if (i == MAX_ATTEMPTS) {
                break;
            }
            try {
                Log.d(TAG, "Sleeping for " + backoff + " ms before retry");
                Thread.sleep(backoff);
            } catch (InterruptedException e1) {
                // Activity finished before we complete - exit.
                Log.d(TAG, "Thread interrupted: abort remaining retries!");
                Thread.currentThread().interrupt();
                return;
            }
            // increase backoff exponentially
            backoff *= 2;
        }
    }
    String message = context.getString(R.string.server_register_error,
            MAX_ATTEMPTS);
    CommonUtilities.displayMessage(context, message);
}

/**
 * Unregister this account/device pair within the server.

static void unregister(final Context context, final String regId) {
    Log.i(TAG, "unregistering device (regId = " + regId + ")");
    String serverUrl = SERVER_URL + "/unregister";

    } catch (IOException e) {
        // At this point the device is unregistered from GCM, but still
        // registered in the server.
        // We could try to unregister again, but it is not necessary:
        // if the server tries to send a message to the device, it will get
        // a "NotRegistered" error message and should unregister the device.
        String message = context.getString(R.string.server_unregister_error,
                e.getMessage());
        CommonUtilities.displayMessage(context, message);
