The ADB profiler is a custom script which provides
|
|
* Battery statistics - battery.csv
|
|
* Memory statistics - memory.csv
|
|

|
Enabling USB debugging can differ by device, see https://developer.android.com/studio/debug/dev-options
|

|
|
1. Connect the Android device to the computer via USB cable

|
|
* `adb_ip=<ip_address>`, i.e., adb_ip=10.4.123.244
|
|

|
|
* `adb connect $adb_ip`
