Systems and methods for prefetching relevant information for responsive mobile email applications

A server configured for fetching data for an application operating on a client device, comprising:

• one or more processors, a memory coupled to the one or more processors;
• and
• one or more programs, stored in the memory, configured for execution by the one or more processors, the one or more programs comprising instructions to:
• at a server:
• receive a request for a list of conversation headers from a client device,
• fetch conversation headers associated with the requested list of conversations, wherein each conversation comprises one or more messages;
• fetch up to a predetermined number of messages, within conversations in the list of conversations, determined to be most relevant to a user of the client device in accordance with predefined criteria stored at the server, wherein the messages determined to be most relevant to the user of the client device include a plurality of messages selected from conversations determined to be most active among the conversations associated with the list of conversations;
• and
• transmit the fetched conversation headers in conjunction with the fetched messages to the client device.

A method for receiving fetched data for an application operating in a client device, comprising:

• at a client device having one or more processors and memory storing programs executed by the one or more processors to perform the method:
• sending, to a remote server, a request for a list of conversations;
• receiving, from the remote server, content associated with the list of conversations, comprising:
• conversation headers associated with the list of conversations, and up to a predetermined number of messages, determined to be most relevant to a user of the client device in accordance with predefined criteria, within the conversations in the list of conversations, wherein each conversation comprises one or more messages, wherein the predefined criteria are stored at the remote server, and the messages determined to be most relevant to the user of the client device include a plurality of messages selected from conversations determined to be most active among the conversations associated with the list of conversations;
• and
• displaying the list of conversations based on the received conversation headers.

A client device for receiving fetched data for an application operating on the client device, comprising:

• a display, an input device, one or more processors, a memory coupled to the one or more processors, a communication interface;
• and
• one or more programs, stored in the memory, configured for execution by the one or more processors, the one or more programs comprising instructions to:
• at a client device:
• send, to a remote server, a request for a list of conversations;
• receive, from the remote server, content associated with the list of conversations, comprising:
• conversation headers associated with the list of conversations, and up to a predetermined number of messages, determined to be most relevant to a user of the client device in accordance with predefined criteria, within the conversations in the list of conversations, wherein each conversation comprises one or more messages, wherein the predefined criteria are stored at the remote server, and the messages determined to be most relevant to the user of the client device include a plurality of messages selected from conversations determined to be most active among the conversations associated with the list of conversations;
• and
• display the list of conversations based on the received conversation headers.

A non-transitory computer readable storage medium storing one or more programs configured for execution by a computer system, the one or more programs comprising instructions for:

• at a server:
• receiving, from a client device, a request for a list of conversations;
• fetching conversation headers associated with the requested list of conversations, wherein each conversation comprises one or more messages;
• fetching up to a predetermined number of messages, within conversations in the list of conversations, determined to be most relevant to a user of the client device in accordance with predefined criteria stored at the server, wherein the messages determined to be most relevant to the user of the client device include a plurality of messages selected from conversations determined to be most active among the conversations associated with the list of conversations;
• and
• transmitting the fetched conversation headers in conjunction with the fetched messages to the client device.

A method for fetching data for an application operating on a client device, comprising:

• at a server having one or more processors and memory storing programs executed by the one or more processors to perform the method:
• receiving, from a client device, a request for a list of email threads;
• fetching thread headers associated with the requested list of email threads, wherein each email thread comprises one or more messages;
• fetching up to a predetermined number of messages, within email threads in the list of email threads, determined to be most relevant to a user of the client device in accordance with predefined criteria stored at the server, wherein the messages determined to be most relevant to the user of the client device include a plurality of messages selected from email threads determined to be most active among the email threads associated with the list of email threads;
• and
• transmitting the fetched thread headers in conjunction with the fetched messages to the client device.
