When do i wipe dalvik cache

Let me start by saying that I've never, ever wiped my dalvik cache and never experienced problems that would be solved by doing so. Because it's not odexed, there is no way there can be multiple o dex files present, and thus on boot the old file is replaced by a newly generated one.

Oh and if it's a really big deal why don't the developers add this into the updater script? I will check out the source, thanks. Possibly just the system ones. Thanks for the detailed answer t0mm13b. Just so I'm clear It seems the simple answer to the question posted is "You don't.

People still think it's and don't realize how cache works in Android nowadays. Deleting it will make your phone slower and your battery drain faster for up to a month. It won't fix anything.

Since Android Nougat, apps are no longer pre-optimized when installed. Instead, they are profiled during use, and then optimized when your device is charging. This allows for better optimizations with less errors. Before the app is completely optimized, it runs with sub-optimal efficiency, meaning it will have lower performance and higher battery drain. Optimized code is stored in the dalvik cache folder. It can take a long time to completely optimize all your apps.

By wiping that folder, you are resetting the whole process. Wiping cache won't fix any issues , because if an error is found in the optimized code, the system will automatically cancel it. It doesn't need your help in doing that, really. Of course, if the ROM maker recommends that you do a factory reset during an update, then it's a good idea to follow their recommendation.

The vast majority of ROMs wipe system as part of the zip install. This means that in most cases you do not need to wipe system At this point, cache not dalvik cache is primarily used for recovery. You probably don't need to wipe cache, and cache is already wiped as part of a factory reset. In most ROMs, dalvik cache is stored in the data partition, so if you do a factory reset, you've also wiped dalvik cache.
