The video appears to be inaccessible unless access has specifically been

There has a crash error when i use libreoffice in android which is
compiled from the source code.
*The development information:*
the libreoffice branch is *master*(update when a write this mail)
*phone information:*
android sdk : *29(android 10)*
brand*:**HUAWEI HMI-AL100*
ram*:6G*
screen*:2244x1080*
Does that device have a 64-bit ARM processor?
*The triggering scenario for this error：*
This error appears more frequently when load xlsx file(load other
file also happen).
when l load xlsx file and zoom in the document then slide up and
down quickly (the video in the accessorias) the app will be crashed
suddenly.
i.e. the crash is not 100% reproducible? Can you give a rough estimation
of how often it happens? (like "almost always", "about every third
time",...)?
It might also help to share a sample doc (e.g. attaching one to a bug
report on Bugzilla) if it happens more often with specific files.
the full error log is below
[...]
*What i have try:*
I think the key point log is
org.free.dike.ldoffice E/LibreOffice/androidinst: SalAbort:
'Unspecified application error'
so i searched this message in the source code and finally found it's
in this method: "vcl/source/app/salplug.cxx -> void SalAbort( const
OUString& rErrorText, bool bDumpCore )"
And i search the method 'SalAbort' to found out the possible invoke
chains.But when i reached method "void
Desktop::Exception(ExceptionCategory nCategory)" in
"desktop/source/app/app.cxx" which i think is most possibly invoke
point trigger this crash. But unfortunately i have not found who
invoke this method. I want to use gdb to debug but when i try to
compile a new so which contain needed symbols and debug info i meet
a link error again(clang++ error:unable to execute command Killed)
which i think cause by low memory of my computer,But i can't change
it...
Finding a working combination of NDK version and linker that work for a
specific architecture and debug configuration can be a bit tricky.
What does your autogen.input look like? (Or what options are you passing
to ./autogen.sh manually?)
For a 64-bit ARM debug build, using LLD with NDK 22.1.7171670 worked for
me in the past, by applying this change on top of master:
https://gerrit.libreoffice.org/c/core/+/130947
and then using an autogen.input containing this:
--build=x86_64-unknown-linux-gnu
--with-android-ndk=/home/michi/Android/Sdk/ndk/21.0.6113669
--with-android-sdk=/home/michi/Android/Sdk
--with-distro=LibreOfficeAndroidAarch64
--enable-sal-log
--with-external-tar=/home/michi/development/libreoffice-external
--enable-ccache
--enable-ld=lld
--enable-dbgutil
--with-jdk-home=/usr/lib/jvm/java-11-openjdk-amd64/
(Maybe requiring newer NDK versions and switching to LLD for all
architectures might work by now, but that would need some more testing.
At least this didn't work for all architectures with older NDK versions
~2 years ago.)
So could you give me some suggestions how to solve this error
In addition to the above, you could try whether it crashes the same way
with a daily build provided by TDF, available here, to see whether it's
in some way related to your build setup:
