Hi @husam88 , Are you using the code in the master branch? Can you please also post your command line here?

hi @ylimit I'm working on a new input generation policy. I got the above issue.

Also, I'm facing this issue when I run the original droidbot on most of (f-droid repository) apps. I used : droidbot -a <path_to_apk> -o output_dir by using: Android emulator API19 kitkat.

APK: https://f-droid.org/en/packages/com.evancharlton.mileage/

I'm getting this error. INFO:Device:disable minicap on emulator INFO:DroidBot:Starting DroidBot INFO:Device:waiting for device Traceback (most recent call last): File "/home/husam/Desktop/env10/env10/droidbot/droidbot/adapter/droidbot_app.py", line 140, in listen_messages _, _, message_len = self.read_head() File "/home/husam/Desktop/env10/env10/droidbot/droidbot/adapter/droidbot_app.py", line 131, in read_head header = self.sock_read(DROIDBOT_APP_PACKET_HEAD_LEN) File "/home/husam/Desktop/env10/env10/droidbot/droidbot/adapter/droidbot_app.py", line 122, in sock_read raise EOF() EOF

Droidbot is not able to start any of my App's under test.
