a processing device communicatively coupled to the memory, the processing device to perform operations comprising:

receiving, during playback of a content item in a cross-application content player within a first user interface of a first mobile application, an indication of a user request pertaining to a second mobile application, wherein the first mobile application is associated with a first platform, and the second mobile application is associated with a second platform;

identifying a play state of the content item at a time corresponding to the user request;

causing the playback of the content item to continue in the cross-application content player within a second user interface of the second mobile application based on the play state, wherein the first user interface of the first mobile application and the second user interface of the second mobile application are presented on one or more client devices, and wherein the cross-application content player persists on the first user interface and the second user interface to provide the playback of the content item in a continuous manner;

detecting an input event initiating sharing of the content item, the input event corresponding to a user interaction with the cross-application content player; and

causing the content item to be shared with cross-application content player in response to detecting the input event.

14. The system of claim 13 , wherein detecting the input event comprises detecting a gesture to move the cross-application content player within the second user interface.

15. The system of claim 13 , wherein causing the content item to be shared comprises causing information related to the content item to be pasted in a text box in the second user interface.

16. The system of claim 13 , wherein the user request pertaining to the second mobile application comprises a request to share the content item using the second mobile application.

17. The system of claim 13 , the operations further comprising:

receiving a first indication to dismiss a notification interface, wherein the second user interface comprises the notification interface; and
