It is very difficult to get the timing right when it comes to synchronizing multiple tracks by hand. But even if I manage to start all tracks at the same time, they will drift apart because they have slightly different durations. There should be an easy and straight-forward way to:

• Start tracks at the same time
• Record tracks with the same length (or a multiple of this length)

This could be done by saving the offset when pressing record in relation to the currently looping tracks. That way the app can auto-align the newly recorded track and line it up with the rest.

Note: Sometimes a delay sneaks into the recording, even if I press record at the same time as I make my sounds. This leads to a short, but noticable pause after hitting play, which makes synchronization even harder. Maybe the app is not accounting for Android's audio latency. I don't know.

sometimes it dosent record a new sample. after a few retries it works.

Hi, this is actually a feature request. It would be great to have a timer, or even better if the recording button function had start/stop, so that you could play after touching it and then stop. And an editor to cut it, be it from the begining or the end, so that you could remove stops and all that stuff.
I would try to implement it myself, but I just have basic programming skills...
Great app for the rest 👍

Add a simple Hold -> Make sound -> Release round button to record a sample text.

when pressing the main button briefly, the app crashes with "Unfortunately, LoopBoard has stopped".

admittedly, that's exactly not what the button tells the user to do, but can happen accidentally or with new users.

this behavior was observed with version 1.4 as packaged in fdroid on a cyanogenmod11 device.

The Sample.stop() method causes the application to crash on my device (HTC One, Android 5.0.2).

I've added some logs, since you didn't use any. This should guide us into the right direction..

I think it would be helpful to add compiling instructions, if contributions are accepted that could make it easier to contribute.
In addition to that, maybe some files could be commited to make things easier like a gradle folder, but maybe it's because of the way I'm trying to build it, are you using android studio?

You accidentally checked in the local.properties file.
A quick look into that file should show you, that it's not supposed to be on GitHub.

"Currently, the application can record sounds through the microphone (or use sounds from internal storage!)" -- but how ?
