QT_ANDROID_MAX_PREPOPULATED_ASSETS_CACHE_SIZE

[TopNotch_Mach07]

While deploying Qt Project to android i am getting this error

[WARN | default] Prepopulated cache is too large to read.

LOGCAT: W Custom ApplicationManager: Use environment variable QT_ANDROID_MAX_PREPOPULATED_ASSETS_CACHE_SIZE to adjust size

Can any one point me what is this environment variable and how it is used.

Thanks,

Hi,

@TopNotch_Mach07 said in QT_ANDROID_MAX_PREPOPULATED_ASSETS_CACHE_SIZE:

QT_ANDROID_MAX_PREPOPULATED_ASSETS_CACHE_SIZE

Just a wild guess but if not the Build environment, you can put it in the Run environment part of the Project panel.

The thing is I don't know what value to set to that variable. While googling I found that this comes from qandroidassetsfileenginehandler.cpp class.

and it is used to set the cache size.

on line no : 280 , It uses something like 1024LL * 1024LL , which is 1048576 in Bytes I guess.

Say , If want to set it to 50 MB of cache size , How can I set that ?

something like
QT_ANDROID_MAX_PREPOPULATED_ASSETS_CACHE_SIZE =52428800 ??

From the looks of it, I would say yes.

Giving the parameter in qt creator environment variable didn't work. But using qputenv() environment variable worked.
