General :: What Does Wipe Cache Do

May 17, 2012

What is being wiped when we apply "Wipe cache" option from recovery menu? So what does "cache" in the recovery menu refers to? Is doing this useful, without firmware update or wipe data-factory reset?

General :: Can't Wipe Dalvik Cache

Jun 19, 2012

I was flashing CM9 from CM7 on my Motorola Defy, botched it up intially due to a slip of my finger which led to me to Clear the cache first. But then I restarted the entire process by Clearing Data -> Installing -> Flashing Kernel and so on...

But when I tried to clear the Dalvik Cache, the phone didn't delete it. It didn't give me a message that it wiped the cache, but it didn't say otherwise either. This led me to believe that the cache just didn't exist anymore.

As a result, I'm unable to install apps - Says there is no memory and I need to make more. Also, everytime the phone comes on is treated as the first time. It takes me through the whole process of Setting up an account and everything. This has rendered my phone obsolete.

General :: FTFs Flashtool Does Not Show File List And Neither Wipe Cache Or Data

Dec 19, 2012

OK, before I start, it's about an LT15i. I don't know what's happening, but at some .FTFs Flashtool does not show the file list (middle column) and neither "wipe cache" or data and one FTF has the "wipe cache" option only. This is really annoying. Tutorials specify a download link for a specific FTF and after starting Flashtool and selecting the flash option, that FTF is not showing up properly. Should I download an earlier version of the program?

HTC Incredible :: Wipe Cache Only?

Sep 2, 2010

If you went and wiped cache only, not data, and installed a new rom, would all data remain? What exactly is this cache that nandroid wipes?

I'd like to install a rom for a friend but dont want to completley wipe his phone. I just want to install the virtuous rom, which is basically the stock 2.2 update rom and would like to keep all his data on the phone. would just wiping the cache work? I know some people just install without wiping but would wiping cache help?

And I know a wipe is always better, thats what I do on my phone. But its not mine and would like to save his data.

Motorola Droid :: Data And Cache Wipe Before Installing Rom

Oct 6, 2010

I'm considering installing a rom and I've heard that doing a data and cache wipe is the proper thing to do to ensure success. What I'm concerned about is how easy it is to restore/re-do all of your settings like ringtones, notification settings, app settings etc. How long does it usually take you to set up your phone again after installing the new rom?

Motorola Droid :: Wipe And Delete Data & Cache?

Aug 5, 2010

If you do not root, you could go from 2.0.1 to 2.1 with no wiping of data and cache, it just installs & away you go. Same with 2.1 to 2.2. No wiping of data and cache and all is still there as you left it: apps, settings, preferences, etc. SO, why is it important to do this if you root? What's the difference? And, who said it was important to do? Is there some exact proven logic on why if your rooted you must do this and if not, your somehow fine? That 1 step difference causes a lot of extra work, so I am wondering why this is said to be a must for rooters and non rooters need not do it when they get updates?

Motorola Droid :: Do I Have To Wipe Cache - Data Before I Flash My Nandroid Backup

Sep 17, 2010

I have installed UD8 for about a week now. But ever since I have flashed some kernels (slayers 1100lv, chevys 1100 lv, p31200) I have not had the stability nor the quickness that the original 800 stock kernel gave.

I made a nandroid backup b4 flashing those roms..so my question is this: Do i have to wipe cache/data before i flash my nandroid backup? Or can i just flash it w/o doing any extra steps?

General :: Disable Moving Of System Dalvik Cache To /cache?

Aug 16, 2012

In cm roms, dalvik cache of system apps are generated in /cache but those data/apps are generated in /data. Is there any way to disable this behaviour? Cache partition in our phones is too small. In AOSP and AOKP and stock roms, dalvik cache is always generated in /data no matter whether its a system app. any way to achieve this in cm roms?

Android :: Android - Image Cache Stategy And Memory Cache Size

Jun 21, 2010

I'm implementing an image cache system for caching downloaded image.

My strategy is based upon two-level cache:
Memory-level and disk-level.

My class is very similar to the class used in the droidfu project

My downloaded images are put into an hashmap and the Bitmap objet is wrapped inside a SoftRererence object.

Also every image is saved permanently to the disk.
If a requested image is not found into the Hashmap<String,SoftReference<Bitmap>> it will be searched on the disk, readed, and then pushed back into the hashmap. Otherwise the image will be downloaded from the network.

Since I store the images into the phisical device momery, I have added a check for preserve the device space and stay under a 1M of occupied space:

CODE:.................

This method is called sometime afte a disk writing:

CODE:..............

What I'd like to add is the same check on the HashMap size to prevent it will grow too much. Something like this:

CODE:.....................

My question is:
What could be a right MAX_MEMORY_SIZE value? Also, Is it a good approach? A good answer also could be: "Don't do it! SoftReference is already enough"

General :: HTC One / No OS After Wipe

Mar 5, 2014

I have an HTC one developer edition, I did an advance wipe of my phone because it wasn't charging, it said that USB Host mode was on. It only charged when the phone was off. I decided to wipe everything but the pictures (or so I thought) but once it finished the wipe the entire OS systems was erased, know the only thing I can do is enter TWRP. I just bought the phone!

General :: Data Wipe / Reset Through ADB?

Mar 30, 2012

what exactly does a data reset do? Does reformat (a) partition(s)? If so, which? If not, which files/directories are removed; What exactly IS deleted? Second, how would I do a data reset through ADB?

My screen is basically broken. It works for a split second when first starting up (cold boot), and flickers off and doesn't turn on. Everything else works. I'm planning to resell for parts; I think I've invested way too much for this phone (screen broke before, and then got stolen, and now broken screen again). I would like to erase all data on the phone. I would normally do this through Clockwork recovery, but can't on the account of being blind due to broken screen.

I did come across this thread, but it still left me questions. Is reformatting system necessary? How would reflash my ROM via ADB? What about wiping Dalvik cache? Is dalvik stored within the cache partition?

As for the phone itself:

Samsung Galaxy S Epic 4G (Sprint)
RandomROM Thunkderhawk 3.5
USB Debugging enabled.

General :: Delete Text Cache?

Oct 24, 2013

I was sending a text and input the wrong phone number (a 2 at the end instead of a 3) and now every time I starting inputting that phone number to send a text both numbers come up. I can't find any way to delete the one that is incorrect or any way to delete both or to delete all of the numbers that show up that way. Is there a text cache that can be deleted? I used app cache cleaner, but that didn't work.

General :: How To Limit Cache Size

Jun 9, 2012

I do really love cloud computing... But, Google seems to have forgot something: set a limit to the cache size.

I have a Nexus S and my poor 16Gb internal memory is saturated because of caches: Google+, Android Gallery (Picasa), Google Music and Google Listen all fight for the sdcard space.

The only apps who have explicit cache settings is Google Listen... The others don't have obvious options. I have 10K songs, 10-20K photos, etc.. I need to access them, but I need to limit the cache size.

Is there a way to easily limit cache size per apps?

General :: Nandroid - How To Backup Cache

Apr 20, 2012

I just came across my first downfall with moving the dalvik to SD. Nandroid is stuck trying to backup cache. Im guessing the reason is that nandroid cant find the dalvik because it is not symbollically linked by S2e since we arent booted into the actaul OS. Anyway i can get nandroid to backup without moving it back?
