I've been working with Android since my Azure Spatial Anchors days, when I was working on a number of client SDKs, including native and Java versions.
These days I'm working on a Mac more frequently than on Windows, and so occasionally I'll use a quick one-liner to wait for a device to be recognized by adb after plugging it in.
Here goes in one go: while true; do if (adb devices | grep device$); then echo found; break; else echo waiting for device ... ; sleep 5; fi; done
As usual, it's nice to get a clearer breakdown of what this does ...
while true; do ... done takes care of looping forever; we'll break from within when we see a connected device.if (...); then echo found; break; else echo waiting ...; sleep 5; fi; has the logic to print out a success message and break out of the loop, or to print a waiting message and sleep for five seconds.adb devices | grep device$ does a query for available devices and runs it through grep to find a line that ends with "device". Another method might be to count lines, but I like this one a bit better. Happy Android development!
