Not all phones have a flash right next to the main shooter, and because of that it's not always possible to cover both the camera and flash.
Therefore I ask for camera selection dialogue to be added in settings

I am finding Heartbeat very useful. I would like to have a New Measurement button on the main screen, so I could start a new measurement with a single click.

Maybe introduce a second line or just show pulse?

Is it possible to open this project in android studio and run the app ?

When i tried to open this project in android studio, gradle sync is failing and also i got a warning as
Warning: License for package Android SDK Build-Tools 29.0.2 not accepted.

I'm using Android Studio Version 4.2 Beta4

i like to see a dark mode feature for the app.

Could you please make an APK file available for download? Most projects attach it to the corresponding release (at releases/), which would be very fine. Thanks a lot in advance!

Hi, I am not sure if this is device specific, but my flash led gets so hot that I can't press my finger onto it after a few seconds. I just checked that this is not the case when I switch it on using the torch tile in my quick settings.

If there is any information that could help you track down the root cause, I'll try to provide it.

Please consider using Fourier transform to improve pulse detection and filter out noise.
There are a lot of libraries to do this.

Cause

Breaking on <string name="dateFormatGranular">yyyy-MM-dd\'T\'HH:mm:ss.SSSXXX</string>

new SimpleDateFormat(

• XXX pattern is not supported prior to Android 7.0. See https://stackoverflow.com/questions/44588429/unknown-pattern-character-x-when-using-simpledateformat
• Affects Android 6.0 and earlier (API 23-)

Describe the bug

Dear developer!
In the process of using, I found a bug in layout / display. As shown in the figure below, on the main page, pulse indicating texts are blocked. Because the textedit element is not scrollable therefore the introduction texts of usage could not be seen fully. This may be an adaptation problem. I suspect it is because display and font size are set to large (mainly due to display size).

App version is 2.1.0, my mobile phone is Google Pixel 2, and the screen resolution setting is 1920* 1080. And my font size and display size are the largest ! ! ! Also, my Android system version is 10.0.
The above is a description of the problem. The overall experience of the software is good. You can see that the design is very attentive. Thank you very much for the efforts of the developers all the time. I hope to receive a reply. Thank you so much!!

Expected behavior

I hope that I can see all of the texts fully, and in this circumstance, part of them seem to be blocked.

Steps to reproduce the behavior:

1.use the largest font and display in the display setting
2.open this app and wait
3.this error could be seen

Screenshot

Environment

1. Version of Heartbeat: 2.1.0
2. Device : Google Pixel 2,
3. OS version : Android 10.0

Cause

Note: I verified this issue also happens in v1.2, so this is not caused by v1.2.1.

• onRequestPermissionsResult only is supported in API 23, this is when Android introduced individual permissions enable/disable

Solutions

1. minSDK can be bumped up to API 23 (Android Marshmallow 6.0).
   -- According to Google stats as of Aug 18, 2021: Android 6.0+ holds 84.9% marketshare.
   -- Users on Android 5.0 and 5.1 would no longer be able to install the app (it would crash for them currently anyway).
2. Remove super.onRequestPermissionsResult(requestCode, permissions, grantResults), this is a callback stub anyway

When trying to start a new measurement if a measurement is already running.

The app crashes when the camera sensor is not available

Hi

If I dont put any finger on the camera , it detects an heartbeat. Clearly it's not an heartbeat and the app should sense the difference.
