After a configurable amount of time, sdbviewer updates the songs from a URL. If this update fails, there is no data in sdbviewer. The old data should be only deleted / discarded if the update succeeds - else it should stay usable.

I've downloaded and installed apk file from GitHub:
SDBViewer_1.2_2019-01-06-08-45-47_release-signed.apk

This app cannot open any URL - neither HTTP nor HTTPS. The file in URL exists definitely. Opening URL in mobile browser on same device works.

My device is a Xiaomi Redmi 5 plus (rooted) with Android 7.1.2.

Screenshot and extracted logcat are appended.

• It should be possible to mark indiviual songs as "starred" (and back).
• There should be a button/icon to switch the list view to "starred only" (and back).
• The user should be able to "un-star" all songs at once.

The purpose of this is to allow for creating a set list for a worship session. The musicians can use a tablet and mark the songs planned for the session, then switch to "starred only" and use the list to easily jump from song to song.

In SDB, there is the possibility to enter a chord sequence (which essentially means one or more lines of chords, corresponding to the verse, chorus and bridge parts of the song).

This chord sequence should be displayable also. It should be fixed at the bottom of the screen - the rest of the text (including chords contained in the lyrics) should still scroll. There should be a new entry in the display settings to enable or disable it.

Hi Mathis,
Nice App!
Yanni asked for another feature for playing songs with Chords with the guitar.
There, a "autoscroll" feature with adjustable speeds would be nice so that the guitar player doesn't need another person to scroll or doesn't need to stop playing to scroll.

Grüße und bis Sonntag ;)
Fabian

It should be possible to import all settings (including the address from which the songs are loaded) by scanning a QR code.

The QR code should be of type "text" and contain a JSON structure with the settings.

see https://developer.android.com/guide/topics/data/autobackup

provide a search functionality

Expected behavior

The users should be able to access Settings section on the SDB Viewer Application.

Actual behavior

When I tried to click on settings in SDB Viewer, the application gave an error and crashed immediately.

How to reproduce

• Open the SDB Viewer app.

• Then click on the Settings.

• And you will see that the application crashes immediately.

• App version: 1.3

• Operating system: Android 5.1.1

Recording Of The Bug

The app should have a place where the user can access

• metadata of the app (version number, developer contact data...) and
• a help text on how to use the app.

The font sizes for lyrics, chords and chord sequence should be configurable by the user.
