Why I get permission denied on ADB on Android phone?

before actually running adbcontrol you must specify paths in config file

check adb connection is working fine (previously authorized) and find a writeable location on device, for example

/sdcard

/storage/emulated/0

/data/local/tmp

depending on encryption and lock screen the location might not be available in this boot state, so better double check adb push is working

adb push ~/file.txt /sdcard

now open the config.properties file and define paths

adbCommand = adb

screenshotDelay = 100

localImageFilePath = adbcontrol_screenshot.png

phoneImageFilePath = /sdcard/adbcontrol_screenshot.png

if your adb binary is not in env you must specify path in first line. for windows paths backslash should escaped like

adbCommand = C:\\Android\\platform_tools\\adb.exe

when configured you can finally run adbcontrol from command line. the terminal will floated by debugging log (you can minimize). another window will open showing your phone screen. your keyboard and mouse input is recognized in android now

java -jar adbcontrol.jar
