MashReDroid: enabling end-user creation of Android mashups based on record and replay

Jiahuan Zheng, Liwei Shen, Xin Peng, Hongchi Zeng, Wenyun Zhao
2020 Science China Information Sciences  
In this paper, we propose MashReDroid, an end user programming approach for the creation of Android mashups that incorporates the behaviors of backend apps into the execution of a host app.  ...  It then allows end users to create mashups by recording the interactions between host apps and backend apps and run mashups by replaying the interactions.  ...  When the execution of the backend app ends, the returned result is shown in a floating panel on the current window of the host app. MashReDroid implements cross-app communication by intent broadcast.  ...
