You can use Magic text '[storage_internal_total]' and '[storage_internal_free]'.Can macrodroid show free RAM of the system? I cannot find any action to do this.
You're right. It's the reason why there is '[storage_external_total]' and '[storage_external_free]' too.RAM and storage are different.
OP asked how to get free RAM space.You're right. It's the reason why there is '[storage_external_total]' and '[storage_external_free]' too.
It's the reason why [storage_internal_total/free] is the closest value to 'RAM'.internal storage is a kind of NVRAM(Flush ROM).It is the same as external strange just working for the same use. RAM is a work space to execute apps, hold data, read/write cash for slower storage etc.
If you only had 128MB left you nearly couldn't run any new app: it's far too short for most of the app.OP asked how to get free RAM space.
These magic texts return free/total space of external storage, i.e. 24GB/128GB. Free RAM is such as 128MB/5.4GB.
