[BUG] Unable to open works view of composers in Android App

[kobberstik]

For several days, it is no longer possible for some composers to open the works view of a composer in the Android app when clicking on the composer name. When clicking on the composer name (e.g., after searching in the "Home" menu), the following error message appears (see also the attached screenshot):

Code: Select all

Attempt to invoke virtual method 'int.com.imslp.data.db.PersonSection.b()' on a null object reference

However, the error does not affect all composers; some can still be opened, but the error appears for many composers. I tried it on three different Android devices (and for one of them, it was a fresh installation), but the error appeared on all devices. Because the works view of the composer can't be opened, it is actually blocking me from downloading some works easily, and I have to search manually for the works in the "Home" view in order to navigate to the work.

Steps to reproduce:

1. Install IMSLP app (if not already done)
2. Open IMSLP app and search for "Andersen"
3. Click on "Andersen, Fritz" and the error message appears

A composer view that is not affected is "Glass, Christian Henrik".

I am also attaching the debugging information from one of my devices. I am using version 3.2.0 of the IMSLP app.

Hi,
I can confirm that the same happens to me on Lenovo Android Tablet.

Hi, I have the same problem on a Samsung Phone and a Lenovo Tablet! Same error code, though I haven't found a composer it still works with.

Thank you for the comprehensive Bug report, I was gearing up to post here, but mine wouldn't have been as detailed xD
