ARP

Android Record and Play. A Java application to record android touch screen , hard key events and playback.

ARP- Android Record N Play.

What is ARP?

ARP- Android Record N Play. Simple java tool helps to record android touchscreen/touchkey/homebutton/powerbutton events and can playback.

How it works ?

Recording-

ARP captures events from input driver(touch,hard key,gpio keys,soft keys) /dev/input/<input_file> for corresponding device and redirects to a file.For this arp uses adb shell getevent to capture events.

Playback-

The events are converted to decimal and send back to /dev/input/<input_file> using adb shell sendevent. But default sendevent utility opens the device file for each "type code value" triplet. This makes playback extremely slow if there are a series of events.

ARP uses a modified sendevent utility which accepts as much type code value triplets and open device file at once and close after write.Below is the diff of sendevent.c . The original sendevent.c is found at https://android.googlesource.com/platform/system/core/+/android-5.0.0_r2/toolbox/sendevent.c.

ARP also inserts delay between touch events by checking kernel timestamp diff of each events.

sendevent.c diff, Original on right side

default sendevent

sendevent /dev/input/event1 3 47 0

sendevent /dev/input/event1 3 57 13578

sendevent /dev/input/event1 1 330 1

sendevent /dev/input/event1 1 325 1

Modified sendevent

/data/local/tmp/mysendevent /dev/input/event1 3 47 0 3 57 13578 1 330 1 1 325 1

How it helps?

How to Run?

Download ARP, Double click. arp.jar.

Next is pretty straight forward.

How to run your recorded events without this tool?

  1. Record your actions as mentioned above.
  2. It will create a timestamp.mel file.
  3. Press play once to verify it is working fine.
  4. It would have created a timestamp.mes file in same location.
  5. Push the timestamp.mes file to any location in your device.eg:-adb push timestamp.mes /data/local/
  6. adb shell sh /data/local/timestamp.mes
  7. Please note: Run timestamp.mes recorded with same device on same model device. if you want try in different device, push /arp_file_location/mysendevent file to /data/local/
