Exploring the Development of Micro-apps: A Case Study on the BlackBerry and Android Platforms
Bibliographic record
Abstract
The recent meteoric rise in the use of smart phones and other mobile devices has led to a new class of applications, i.e., micro-apps, that are designed to run on devices with limited processing, memory, storage and display resources. Given the rapid succession of mobile technologies and the fierce competition, micro-app vendors need to release new features at break-neck speed, without sacrificing product quality. To understand how different mobile platforms enable such a rapid turnaround-time, this paper compares three pairs of feature-equivalent Android and Blackberry micro-apps. We do this by analyzing the micro-apps along the dimensions of source code, code dependencies and code churn. BlackBerry micro-apps are much larger and rely more on third party libraries. However, they are less susceptible to platform changes since they rely less on the underlying platform. On the other hand, Android micro-apps tend to concentrate code into fewer files and rely heavily on the Android platform. On both platforms, code churn of micro-apps is very high.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
