android - 想要使用 Android 设备的解析向用户发送用户通知

Question

我正在尝试通过单击按钮向特定用户发送用户到用户通知，但是在过去 4 天在 android 中发送通知时遇到此问题，并且每当我从我正在使用的手机上卸载该应用程序时作为模拟器，并重新安装它进行调试，它不会创建新的安装 ID 并采用旧的:我猜这是问题所在，如果有人以详细的方式帮助我，那将是很大的帮助

这是我的自定义接收器代码:

public class CustomPushReceiver extends ParsePushBroadcastReceiver {
    private final String TAG = CustomPushReceiver.class.getSimpleName();

    private NotificationUtils notificationUtils;

    private Intent parseIntent;

    public CustomPushReceiver() {
        super();
    }

    @Override
    protected void onPushReceive(Context context, Intent intent) {
        super.onPushReceive(context, intent);

        if (intent == null)
            return;

        try {
            JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));

            Log.e(TAG, "Push received: " + json);

            parseIntent = intent;

            parsePushJson(context, json);

        } catch (JSONException e) {
            Log.e(TAG, "Push message json exception: " + e.getMessage());
        }
    }

    @Override
    protected void onPushDismiss(Context context, Intent intent) {
        super.onPushDismiss(context, intent);
    }

    @Override
    protected void onPushOpen(Context context, Intent intent) {
        super.onPushOpen(context, intent);
    }

    /**
     * Parses the push notification json
     *
     * @param context
     * @param json
     */
    private void parsePushJson(Context context, JSONObject json) {
        try {
            boolean isBackground = json.getBoolean("is_background");
            JSONObject data = json.getJSONObject("data");
            String title = data.getString("title");
            String message = data.getString("message");

            if (!isBackground) {
                Intent resultIntent = new Intent(context, MainActivity.class);
                showNotificationMessage(context, title, message, resultIntent);
            }

        } catch (JSONException e) {
            Log.e(TAG, "Push message json exception: " + e.getMessage());
        }
    }


    /**
     * Shows the notification message in the notification bar
     * If the app is in background, launches the app
     *
     * @param context
     * @param title
     * @param message
     * @param intent
     */
    private void showNotificationMessage(Context context, String title, String message, Intent intent) {

        notificationUtils = new NotificationUtils(context);

        intent.putExtras(parseIntent.getExtras());

        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

        notificationUtils.showNotificationMessage(title, message, intent);
    }
}

和我的 ParseQuery:

try {
                    ParseQuery userQuery = new ParseQuery(ParseUser.class);
                    userQuery.whereNear("Location",
                            currentUser.getParseGeoPoint("Location"));
                    userQuery.setLimit(10);
                    userQuery.whereEqualTo("Type", "Doctor");
                    userQuery.whereEqualTo("deviceType", "android");
                    userQuery.findInBackground();
                    // Find devices associated with these users
                    ParseQuery pushQuery = ParseInstallation.getQuery();
                    pushQuery.whereMatchesQuery("user", userQuery);
                    // Send push notification to query
                    ParsePush push = new ParsePush();
                    push.setQuery(pushQuery);
                    push.setMessage("Only users near"
                            + currentUser.getParseGeoPoint("Location")
                            + " will recieve this push notification");
                    push.sendInBackground(new SendCallback() {

                        @Override
                        public void done(ParseException e) {
                            if (e == null) {
                                Toast.makeText(getApplicationContext(),
                                        "Notification Sent", Toast.LENGTH_LONG)
                                        .show();
                            } else {
                                Toast.makeText(getApplicationContext(),
                                        "Notification not Sent",
                                        Toast.LENGTH_LONG).show();
                            }
                        }

                    });

                } catch (Exception e) {
                    e.printStackTrace();
                }

Answer 1

一般来说，

(1) 您将在云代码中执行此操作。幸运的是，一旦开始就非常容易。事实上，这是一个类似问题的完整解释。

不过更重要的是，

(2) 请注意，您使用的工具不当。 您不使用“推送”来实现您想要实现的目标。您应该使用 PubNub、Firebase、Pusher 或类似的服务。将其中一种与 Parse 结合使用是司空见惯的事情。
