Sending messages from smart speakers and smart displays via smartphones

A method implemented by one or more processors, the method comprising:

• receiving, by a first device, a request from a first user to send a message to a second user;
• determining that a messaging application corresponding to the request is unavailable on the first device;
• and
• in response to determining that the messaging application corresponding to the request is unavailable on the first device:
• determining, by the first device, an account of the first user based on contextual information;
• selecting a second device on which the messaging application corresponding to the request is available, based on the account of the first user;
• and
• sending, to the second device, a command that causes the second device to send the message from the first user to the second user using the messaging application on the second device.

A method implemented by one or more processors, the method comprising:

• receiving, by a first device, a request from a first user to send a message to a second user;
• determining that a messaging application corresponding to the request is unavailable on the first device;
• and
• in response to determining that the messaging application corresponding to the request is unavailable on the first device:
• selecting a second device on which the messaging application corresponding to the request is available;
• and
• sending, to the second device, a command that causes the second device to send the message from the first user to the second user using the messaging application on the second device,
• wherein:
• the request specifies the messaging application, and
• the messaging application utilizes end-to-end encryption to send the message from the second device to a third device that is associated with the second user.

A method implemented by one or more processors, the method comprising:

• receiving, by a first device, a request from a first user to send a message to a second user;
• determining that a messaging application corresponding to the request is unavailable on the first device;
• and
• in response to determining that the messaging application corresponding to the request is unavailable on the first device:
• selecting a second device on which the messaging application corresponding to the request is available;
• and
• sending, to the second device, a command that causes the second device to send the message from the first user to the second user using the messaging application on the second device,
• wherein the command is interpreted by a second automated assistant application running on the second device to cause the second automated assistant application to respond by treating the request as being received directly by the second automated assistant application running on the second device.

A method implemented by one or more processors, the method comprising:

• receiving, by a first device, a request from a first user to send a message to a second user;
• determining that a messaging application corresponding to the request is unavailable on the first device;
• and
• in response to determining that the messaging application corresponding to the request is unavailable on the first device:
• selecting a second device on which the messaging application corresponding to the request is available;
• and
• sending, to the second device, a command that causes the second device to send the message from the first user to the second user using the messaging application on the second device,
• wherein the determining, the selecting, and the sending are performed by a computer server that is external to the first device and the second device.

A computer program product comprising one or more computer-readable storage media having program instructions collectively stored on the one or more computer-readable storage media, the program instructions executable to:

• receive, by a first automated assistant application running on a first device associated with a first user, a message received by a messaging application running on the first device;
• determine, by the first automated assistant application, a second device associated with the first user, wherein the second device is running a second automated assistant application and the messaging application is unavailable on the second device;
• and
• send, by the first automated assistant application, the message to the second automated assistant application running on the second device;
• receive, by the first automated assistant application running on the first device, from the second automated assistant application running on the second device, a command to send a reply message using the messaging application;
• and
• invoke, by the first automated assistant application, the messaging application to cause the messaging application to send the reply message.

A computer program product comprising one or more computer-readable storage media having program instructions collectively stored on the one or more computer-readable storage media, the program instructions executable to:

• receive, by a first automated assistant application running on a first device associated with a first user, a message received by a messaging application running on the first device;
• determine, by the first automated assistant application, a second device associated with the first user, wherein the second device is running a second automated assistant application and the messaging application is unavailable on the second device;
• and
• send, by the first automated assistant application, the message to the second automated assistant application running on the second device,
• wherein the sending the message comprises sending a command that causes the second automated assistant application running on the second device to render the message at the second device.
