'[OT] Android: updates nibbling away at storage'

It seems that every time I update an app in my phone, my available
storage drops by the size of the update package. So if I have an app
that is 16 megs and I've updated it five times, I'm down over 80 megs.
No big deal by itself, but by rough calculations I'm wasting over a
gigabyte to all these useless packages, leaving less room for important
cat videos.

Unfortunately the folder that houses all the install packages is
invisible and unavailable.

Is there an app that lets you zotz these files, or do I need to root my
phone first?

Thanks for any insight.

Bob

I use es file explorer, no root needed. It also identifies potential old
apps to delete, though I'm not watching closely enough to appraise its
judgement.

Hi Lyle,
I'm a little hesitant to install ES File Explorer, I had it on a
previous phone and didn't like it. Reading reviews of the currently
available version it seems like it wants to harvest you for food :) But
it gives me hope that I can find a file manager that will show me the
contents of /data/app.

Although I've been using my Galaxy S4 for several years, I still barely know anything.

That said: I'm using a free app called Clean Master (installed via Google Play).

It seems to do a decent job of scrubbing what it calls "junk files".  The only downside is that it tries to get me to install other crap that I don't see the need for.  No problem declining those "offers" but it is annoying.

That said: it does seem to keep my 16GB phone clean and light.

I used Clean Master for a long while, but I removed it few months ago. Now I cannot remember why, but it was something that annoyed me a lot.
It was cool and easy to use, but I cannot remember if you could remove specific files from the file system.

An ordinary reboot sometimes will clean things up.  Androids lack of housekeeping becomes is on par with 1978.  There is at least one other way to force garbage collection but my recollection is very slow tonight. Its not a new problem, you will recognize it when you see it.

Agreed, it's been a work-in-progress since the HTC One. And since
there's no documentation, we poke around and eventually just get a new
phone, swapping one suite of bugs for another.

Just being able to see all the files and directories would be enough for
me.

BTW, Android 6.01 Marshmallow on a Nexus 6 here.

Best regards, Bob

Bob,

Now on my Galaxy Notes 3, I have an app called "My Files" that does exactly what you want.
You can see the local storage volume and the SD card, including the hidden files.

You can't imagine how much I've griped about the same thing, but never found a good solution.  It gets really bad when I log into an app for an important purpose, it demands I upgrade cause my version is out of date, then says the update is too large for my device.  I too bit the bullet and upgraded to a newer phone.

Cheers,
-Neil.

​There is more, and less, going on than is obvious, alas.
​I had Google & Chrome jointly & severally require me  to upgrade playstore
and related apps to allow them to run at all and then tell me there was not
enough memory space. On web advice was to revert to an older version off
the net then upgrade and all would be well. My phone is still at the
sometimes walking wounded stage and I'm wondering if a "factory reset" may
help.

See - Microsoft wasn't so bad all these years after all ! :-)
This is just "normal" apparently.

I had thought that phone internal memory size was not overly crucial due to
the ability to add largish external uSD memory.
It turns out that too many apps demand to use internal memory and my
relatively low end Huawei does not have enough.

(Bill Gates denies saying (in 1981 or any other time) that 640 kB should be
enough for anyone.)

I am using a Samsung Note3, Samsung tablet is similar.
Push center button until Task Manager appears at bottom left.  The items you see listed can be reached quickly by simply clicking. They are tying up storage (at least). You can close them individually and gain some resources. You also have the choice closing them all and releasing the resources. The manager I spoke with where I bought the phone told me that the users that are happiest are the ones that turn there phones all the way off at least once a day.  You don't really own them, there are several more identities that have greater control than you do.  They are in no way suitable for emergency communications.

They sure are cool when they are working though.

'[OT] Android: updates nibbling away at storage'

I've been experimenting and think I mostly know what Android does.

When you download a new app it comes in a package file and Android
installs from that. It doesn't delete the package, so the total storage
you lose is about double the download size, because you have the
installed app and the package both occupying storage.

If you then update that app, the new package is downloaded and Android
installs from that, overwriting the installed app. The old download
package is deleted at some (unknown) point. so you don't really use up
more storage (except the update is probably a little bigger than the
previous version).

It's a slightly different story for factory-installed apps. There's a
factory package file and the corresponding installed app, but when you
update the app it doesn't delete the factory package file. That means
you now have two package files instead of one. Every update after that
will leave you with the factory package file, the latest update package,
and the installed app.

Bob

The .apk file is a .zip file renamed.
Simply the app file is copied in the apps folder and remains in his format. It's decompressed on fly, without "static" decompression.
But can exists some other data or library that can be downloaded "transparently" during the install.
You have the "double copy" only for apps that you download and than install..

Note that some apps can use a lot of data space, eg. Skype uses, on my phone, near 300MB!

With some apps (eg. Titanium Backup) you can "integrate" updates to roms. Yes, to ROM!
So this operation is potentially dangerous, I broke one of my device (Asus Fonepad 7, with Intel cpu) and had to reinstall completely the firmware. With other device I had no problem, freeing a lot of space...
