How do I clear cache?

In the Blue Magic ROM thread, it says to clear cache on every boot, how would I go about doing that?

in Amon-Ra's recovery there as an option to wipe your dalvix cache. Hope it helps

Actually, it does this every boot by itself.

But if you want to clear it yourself, you can get a cache clearing app off the market like Cachecleaner (free) and just use that. And you can also do what Protomanez said

regular cache is different than dalvik-cache.
regular cache is stored in /data/data/"app.name.here"
while dalvik-cache is stored in /data/
If you clear the dalvik-cache it will take a while for your phone to boot up because it has to reload the dalvik-cache back to your data directory all over again.

[Q] Difference between Factory Data Reset vs CWM Wipe

What's the difference between doing a Factory Data Reset and doing a wipe using CWM.
I'recently rooted my Note and now have CWM installed.
I plan on trying a few different ROMs (both newer stock ROMs and eventually custom ROMs) and read in most instances to per a wipe before upgrading.
I was wondering which wipe to use.
Also, if I install Titanium Backup, will it save everything including Contacts, Network settings, icon layouts, webpage favorites, appa and everything else?
Thanks

Cant say surely about the difference between factory rest of data and CWM wipe. But can surely say to flash any rom you need to CWM wipe all the data and cache and dalvik cache from the recovery.
And Titanium Backup is for backing up and restoring all your apps and their associated data and market links. It doesn't backup contact (should auto backup to your google account or use any contact and sms backing app from market like - https://play.google.com/store/apps/details?id=com.idea.backup.smscontacts&feature=search_result) or
layouts . Icon layouts you can save by going to the backup settings of the launcher you are using and favorites you can again backup on your sd card.

CWM recovery wipe cache, is just wiping cache files not data
while CWM recovery wipe data n Hard reset from setting - privacy - erase data(factory reset) is same
CWM function is useful when you unable to boot device normally.

Where is dalvik cache located ? Because if it's in the data or cache partition, then I don't see why I have to wipe dalvik cache after wiping data/cache...

System apps' dalvik-cache in /cache
Data apps' dalvik-cache in /data
Hence just by clearing the cache you clean the /cache space of system apps and not the dalvik cache of data apps.
So you require to do both - clean cache and clean dalvik cache.

Factory Reset will change your Android ID. Some apps with custom DRM may stop working. Factory Reset is also incompatible with some ROMs and causes some apps/files installed by CWM flashable ROMs to disappear.

I think both are same. Both format data and cache partition.
(that is why devs warned not to perform FDR on affected kernels)
With FDR you initialise the command from booted phone.
CWM Wipe is what you do from recovery mode.

[Q] Wipes and formats

One question, maybe noob ...
When we made flash a new rom from recovery, we made the wipes;
- Wipe cache
- Wipe Dalvik
- Wipe data / factory reset
But
I notice that when you make the wipe all data / factory reset, the system partition is not formatted, it influences the functioning of the new rom?
For sure, I always do the formats in "mount and storage".
- Format cache
- Format data
- Format system
Thank you! Hugs! :silly:

I only
- Wipe Dalvik
- Wipe data / factory reset
I thought when I do wipe data, then I delete the cache.
Sometimes I wipe SD for delete cache & thash of deleted apps.

Ok.
And the system partition?
When you wipe data / factory reset, the system partition is not formatted.
As I know the main files are in the system partition.
Ty for support.:laugh:

From what I can remember reading, when a phone boots up it makes some kind of cache of the installed applications.. it allows the phone to boot up in less time after the initial boot (in the initial boot, its making the cache that's why it takes a long time)..
When you wipe dalvik cache, this cache is deleted.. when you wipe the dalvik cache and boot you'll notice that it makes the cache again..

Extremely noob TWRP question

So I just started using TWRP and its awesome and I wanted to a simple cache partition wipe like you know the wipe cache partition on a stock recovery, so I was wondering if I should just select the Cache option in the Wipe menu or both the Cache and the Dalvik Cache?

i always wipe both, cache and dalvik - never hurts.

Thanks.
