# Sending touch/swipe events to BlueStacks/Android sounds easy but actually it isn't
### There are some "common ways"
##### 1st way:
The standard version on a not rooted system is:
**adb shell input tap x y**
Unfortunately, this method is very slow and unreliable since it calls the Java layer of the android framework:
[https://stackoverflow.com/a/38806872/15096247]()
##### 2nd way:
If your cell phone / BlueStacks instance is rooted, you can use:
**adb shell sendevent /dev/input/event2 3 0 x**
**adb shell sendevent /dev/input/event2 3 1 y**
**adb shell sendevent /dev/input/event2 1 330 1**
**adb shell sendevent /dev/input/event2 0 0 0**
**adb shell sendevent /dev/input/event2 1 330 0**
**adb shell sendevent /dev/input/event2 0 0 0**
This method is a lot better than "input tap" since it is more reliable and slightly faster.
But when you use "sendevent" like in the example above, you won't even get a decent swipe, because
the break between the ADB shell calls just takes too long.
Even using:
**adb shell "sendevent1 ; sendevent2 ; sendevent3 ; …"**
doesn’t improve the executing speed much.
##### 3rd way:
If your cell phone / BlueStacks instance is rooted, you can also use:
**adb shell dd bs=filesize_in_bytes if=./file of=/dev/input/eventX**
This method is very reliable and very very very fast… unfortunately too fast for the Android touch screen.
## sendevent-getevent aims to offer a solution for the execution speed problem.
### Features:
- You can record getevents directly from python, once you are done you press the hotkey (default=“ctrl+x”) to exit the recording session.
- It converts the output into all possible formats: hex - int - sendevent with int - binary data and returns a Pandas DataFrame
- You can define the playback speed of the recorded session (speed 4 is about close to the "original speed")
- You can change the playback speed afterwards
- It is possible to save/load recorded sessions
- You can manually change the DataFrame
- It sends chunked data to the device/emulator using adb shell dd bs=filesize_in_bytes if=./file of=/dev/input/eventX , and sleeps after each chunk
### Tested against Windows 10 / Python 3.9.13 / BlueStacks 5
It should also work with any rooted Android device, the only problem might be the "bluestacks_divider".

But changing the code (if necessary) shouldn't be a big thing.
Since my cell phone is not rooted, and I have no intention of rooting it, I cannot test it with an physical Android device. (I would be grateful for any feedback)
Take a look at the video to see what the code below does:

```python
