To test the Conversation function, send a test message to a friend and verify that the widget updates when the message arrives. Then, use different values of the Conversation status to see which widgets will update. Depending on the conversation status, you can also play different sounds or sets of strings. Let’s try the Conversation function in our Android app. Here are some examples. And if you have any questions, don’t hesitate to ask in the comments below.
RemoveLongLivedShortcuts() deletes all data associated with the conversation
A Conversation Shortcut is a data field that is automatically associated with a specific conversation. If it is present, it can be viewed in the conversation space by long-pressing on it. If it’s missing, the user sees a message stating that the app does not support the conversation feature. Shortcuts should take the user to the right place within the app.
A Shortcut must be associated with a valid long-lived dynamic shortcut or cached sharing shortcut to show up in the Conversations section of a conversation. The notification can set the association by calling setShortcutId() or setShortcutInfo(). Notifications for Android 10 and lower do not need to be associated with a Shortcut.
SpeakStringByStrRef
The SpeakStringByStrRef call in the SpeakString dialog box allows you to specify the string to be spoken. To do so, you must set the string reference. If the string is not found, Ctrl+F will prompt you to search from the beginning. The SpeakStringByStrRef dialog box also includes the PlaySoundByStrRef conversation function.
PlaySoundByStrRef
The PlaySoundByStrRef conversation feature enables you to play a sound from an object by using its reference. To use this function, you must pass in a string reference to the object, called target. You can also specify an amount of messages to be sent, as PAM_MAX_MSG, or limit the number of messages to a certain amount. Another conversation feature is the SetCommandability() function, which allows you to make an object commandable.
PAM_CONV_AGAIN
The PAM_CONV_AGAIN conversation functions allow a PAM module to communicate with the user in a number of ways. To start a conversation, the designer must write a conversation function and pass messages between the user and module. The msg_style parameter in the pam_start() function determines the message type. Messages are returned with an error code if they fail to be recognized.
The PAM_CONV_AGAIN conversation functions are defined in the Linux-PAM Application Developers’ Guide. Each module should implement its own version of pam_conv() to ensure proper logging. The function must be used with care. There are a few considerations when using conversation functions. Make sure to keep this in mind when developing your application. If you need to use PAM_CONV_AGAIN conversations, you should make sure that the application uses the latest version of the PAM library.
PAM_CONV_ERR – conversation method supplied by the application failed to obtain the username
If you’ve ever encountered this error, you know that the conversation method supplied by the application failed to obtain a user name. To fix this issue, first, you need to read the Linux-PAM application developers’ manual and create a new header file. You can find the details about pam_conv here:
There are several ways to implement the conversation function. The developer must write a conversation function, which passes messages between the user and the module. The msg_style parameter determines the type of message that will be sent. The pam_message parameter should be set to an appropriate value. In case of errors, the PAM_CONV_ERR error code will be returned.
