What is the strange behavior of android programs for accounting finance?

Question

Android

A little background: for a long time I wanted to take into account my income and expenses, and then 2 weeks ago I came across a review of the Spendee program. Actually, I liked it and I used it for 2 weeks honestly making my expenses, but after a couple of days it just started to crash at startup.
Having lamented the loss of data on his expenses for 2 weeks, he began to search for other similar beautiful minimalistic programs.
Switched to CoinKeeper:. The next day it just stopped working.
The next was MoneyLover - after the first launch and entering information about the account, it crashes.
Then Monefy. It seems to work, but as soon as I added a new category of expenses, it also constantly crashes.
What could be the reason for such behavior of programs of this particular type? The rest of the applications of other topics work and have always worked without problems.

Answer 1

It's hard to say why it crashes, but they obviously all work with the database and most likely content providers. Maybe Alcatel broke something in the api. Alternatively, check that there is enough space on the data section.
