	att_abstract={{Despite the popularity of mobile applications, their performance
and energy bottlenecks remain hidden due to a lack of visibility into
the resource-constrained mobile execution environment with po-
tentially complex interaction with the application behavior. We de-
sign and implement ARO, the mobile Application ResourceOptimizer,
the first tool that efficiently and accurately exposes the cross-layer
interaction among various layers including radio resource chan-
nel state, transport layer, application layer, and the user interac-
tion layer to enable the discovery of inefficient resource usage for
smartphone applications. To realize this, ARO provides three key
novel analyses: (i) accurate inference of lower-layer radio resource
control states, (ii) quantification of the resource impact of applica-
tion traffic patterns, and (iii) detection of energy and radio resource
bottlenecks by jointly analyzing cross-layer information. We have
implemented ARO and demonstrated its benefit on several essential
categories of popular Android applications to detect radio resource
and energy inefficiencies, such as unacceptably high (46%) energy
overhead of periodic audience measurements and inefficient con-
tent prefetching behavior.}},
