"TransactionTooLargeException: data parcel size 552920 bytes" with large note on activity lost focus

[sadr0b0t]

Hello, I use nextcloud-notes android client 0.24.3 on android 8.

1. Create new note
2. Put inside some large enough text
3. Press "show desktop" or "show opened applications" system button, so the notes activity will lose focus while note editor is opened

result: application crash with exception:

java.lang.RuntimeException: android.os.TransactionTooLargeException: data parcel size 552920 bytes

The note itself stays safe, though.

Evedently, the problem happens when the app activity tries to save its state on activity stop event and exceeds data parcel to save size limit.

How mich data do you have in one note? do you have base64-coded images or such stuff in your notes?

[sadr0b0t]

no pictures, just regular text in unicode, 176KB example: https://pastebin.com/7Hn4rmJg (some citations from the book while reading)

[stefan-niedermann]

Can you specify which phone you are using and how much RAM you have available? I am not able to reproduce this issue with the given pastebin sample.

[sadr0b0t]

I have Mi MIX 2 Android 8.0 6 Gb RAM

Just tried again and got this exception again.

this looks like a kind of internal limitation https://developer.android.com/reference/android/os/TransactionTooLargeException

[stefan-niedermann]

Are you able to reproduce this issue wit another device (or in a virtual machine)?

I still have trouble reproducing it, even with (emulated) low-end-smartphone with 512 MB RAM.

Also the note is less than 200 kB which should really not be an issue... 😕

I noticed that there is a similar problem at https://github.com/mkulesh/microMathematics . Perhaps we can refer to this issue to find more context about the bug (e.g. the cause of this bug, or the hint to resolve it?).

[JenniferJohnson89]

Also similar issue here, here, and here. Maybe you can find applicable fixes in the referred PRs in those issues.
