Kapture - Screen recorder
Kapture is a screen recorder for Android (and Wear OS) that allows to capture microphone audio while sharing it with other apps.
I was looking for an app that allow me to record my screen and microphone while sharing the microphone with other apps, like games.
Unfortunately I didn’t find any inside the Google Play.
The ones I found required sideload, which I was a bit concerned about installing because it required some dangerous permissions and I didn’t have access to the code.
Therefore I decided to build one on my own. I’m also sharing it here. You can download the .apk and install it, or you can download the source code, read it and built it yourself.
¹ Phone gif is from version 1.4.0, new versions might be different (features might change between android versions!);
² Watch gif is from version 1.0.0, new versions might be different.

¹ Starting on Android 14, some devices display a popup informing that the accessibility service is a restricted settings and it is unavailable or that it must be manually enabled when you try to manually enable the accessibility service. In case you are using the ADB command this message will not even show up, the app will just not start a capture. Any of these cases can be fixed by doing the following steps:
- On your Android device, open the Settings app;
- Tap Apps;
-
Tap the app that you want to turn on a restricted setting for (Kapture);
- If you can't find it, first tap See all apps or App info.
- Tap More icon (three dots) and then Allow restricted settings;
- Follow the on-screen instructions.
For more information check the
documentation.
