This topic summarizes the common problems that may appear in the process of integrating and using Message Push Service, and provides the corresponding solutions to solve those problems.

General questions

Description on permissions

For Android 6.0 and later versions, users need to manually grant permissions to the phone, such as reading/writing SD cards. To send messages more precisely, we recommend that developers provide a guide to users on how to grant the required permissions for the notifications.

Logs cannot be printed

For Meizu phones, if log.d and log.i cannot be printed, you can choose Settings > Accessibility Options > Developer Options and turn on Advanced Log Output.

In case of development issues, you can set tag=mpush to filter logs.

Android related questions

Port resolution problems in baseline versions 10.1.60.5 ~ 10.1.60.7

In private cloud environments, for the message push using ports other than 443, the resolution of server configurations will fail, and cause connection errors.

Solution:

If you use the config file for packaging, modify the config file as follows:

  //Ignore the rest of the config file and add \\{white space} before the custom port number.
  {
      "pushPort":"\\ 8000",
  }

If you do not use the config file for packaging, change the value of rome.push.port in AndroidManifest.xml as follows:

  //Add \{white space} before the port number.
  <meta-data
      android:name="rome.push.port"
      android:value="\ 8000" />

Troubleshooting procedure for common Android problems

Check whether the Manifest file is configured correctly.
Check whether the appId (Huawei, Xiaomi, or vivo), appSecret (Xiaomi or OPPO), appKey (OPPO or vivo), and ALIPUSH_APPID (mPaaS) are consistent with the app registration information on the corresponding development platform.
Check the Logcat logs tagged as mpush.

Whether there will be a banner or sound alert for messages when the app runs in the foreground

The default mechanism for Apple is that when an app is in foreground, the messages can arrive but will be not shown. In order to show messages in foreground, you need to implement it manually.

Message status is NoBindInfo

NoBindInfo means the user pushes messages by UserId, but no corresponding information is found based on the UserId. Please check if the client has called the binding API, and if the corresponding appId workspaceId are consistent.

Message status is BadDeviceToken

This status will only appear for iOS pushes, indicating that the actually pushed token is invalid. First, check if the environment of the certificate is correct.

If the app is packaged with a development certificate, the push console configuration requires a development environment certificate, while Xcode requires a developer certificate for debugging in real devices.
If the app is packaged with a production certificate, the push console configuration requires a production environment certificate.

Message status is DeviceTokenNotForTopic

This status will only appear for iOS pushes, indicating that the token is inconsistent with the BundleId of the certificate used in the push. Please check if the certificate is correct and if the BundleId of the certificate is consistent with the BundleId used in client packaging.

The iOS phone cannot receive messages, but the message status is ACKED

For iOS pushes, if the message status is ACKED, it means that the message has been successfully pushed to Apple Push Notification service. Please check if the push permission is enabled and whether you have switched the app to the background.
