It 11 is used by non-swarmed bots to detect any missing/extra devices attached to 12 them. 13 14 This will be no longer needed when all bots are switched over to swarming. 15 16 ## Bots 17 18 The list is usually located at: 19 20 - `~/.android/known_devices.json`. 21 22 Look at recipes listed below in order to find more up to date location. 23 24 ## Local Runs 25 26 The persistent device list is unnecessary for local runs. It is only used on the 27 bots that upload data to the perf dashboard. 28 29 ## Where it is used 30 31 The persistent device list is used in the 32 [chromium_android](https://cs.chromium.org/chromium/build/scripts/slave/recipe_modules/chromium_android/api.py?q=known_devices_file) 33 recipe module, and consumed by the 34 [device_status.py](https://cs.chromium.org/chromium/src/third_party/catapult/devil/devil/android/tools/device_status.py?q=\-\-known%5C-devices%5C-file) 35 script among others. 36
