[Q] Is clearing cache ok?

---

Hi all!

I got an app called "App 2 SD Free" made by Sam Lu today. And it suggesting clearing my app cache (clear app cache, that what it says) and I am confused with what will it do. For example, will it clear my Facebook App sign in data? And is this app cache is Dalvik Cache?

Edit: Oh, guys it's too late. I accidentally cleared it And looks like no change.

Im also a user of that app. And i cleared it many times and nothing happened to me. Sign-in data's will not be cleared even if u clear the application cache and application data (checked for gmail, market).

Cache is a storage space for temporary files. And clearing cache will speed up the applications definitely. And that's also a way to free up memory.

Coming to dalvik cache,
Dalvik cache is a program cache area for the program dalvik. Dalvik is a java based virtual machine that is the bases for running your programs (the ones that have the .apk extension), in order to make access times faster (because there's not JIT compiler installed by default). The dalvik-cache is the result of dalvik doing a optimization of the running program. It's similar to the prefetch files in Windows.

[sorry if im wrong]

Sorry for that. Like i said, i checked it with gmail and market only. Later i came to know that gmail once attached to the wildfire cannot be deleted. The only way to remove gmail is hard reset. And market uses gmail login data.

And im using stock 2.2 wildfire. And i checked facebook for htc sense and plurk. These login data's will also be not deleted by clearing cache/data. And maybe we cannot expect 3rd party apps to retain their login data even after clearing cache/data (example: XDA app).
