kandi X-RAY | DiskLruCache Summary

DiskLruCache is a Java library typically used in Server, Caching applications. DiskLruCache has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has medium support. You can download it from GitHub, Maven.

a cache that uses a bounded amount of space on a filesystem. each cache entry has a string key and a fixed number of values. each key must match the regex [a-z0-9_-]{1,120}. values are byte sequences, accessible as streams or files. each value must be between 0 and integer.max_value bytes in length. the cache stores its data in a directory on the filesystem. this directory must be exclusive to the cache; the cache may delete or overwrite files from its directory. it is an error for multiple processes to use the same cache directory at the same time. this cache limits the number of bytes that it will store on the filesystem. when the number of stored bytes exceeds the limit, the cache will remove entries in the background until the limit is satisfied. the limit is not strict: the cache may temporarily exceed it while waiting for files to be deleted. the limit does not include filesystem overhead or the cache journal so

            How to cache Firebase storage downloaded images
            Asked 2019-Mar-24 at 13:26

            I am developing an app where I need to cache images such that I can retrieve them when the user is offline and they should also be accessible once the user closes and reopens the app.

            I need something like

            I don't fully understand the idea of downloading images by user, caching them but not allowing to display them later.

            You have 2 options here in my opinion.

            First one is to use Glide cache but you dont have full control of when and how images will be cleared.

            Second option is to save images as files in private directory (user won't be able to preview this images) and create some kind of logic in application (based on your restrictions) to control when and how to display those images to users in app.

            Accessing cached Images from LruCache Implementation
            Asked 2018-Nov-15 at 00:51

            I have a GridView with images and i have populated it using Volley and cached the images using the below links. I want to access the selected image of GridView in a new activity from the cached implementation. I have searched here on StackOverflow but could not find how to access the cached images using their key(int this case the URL). i have followed these links but couldn't find anything:

            Do I have to use the same LruCache object created in ImageLoder object in the second activity or is there any other way?

            Imageloader object in Singleton class

            This is the default implementation of LruCache object used. If someone could explain using the code below?



            Answered 2018-Nov-15 at 00:51

            I have found the answer here

            The reason was that i had resized the ImageView while getting the image from cache. Cache only returns the image that has the size that of the originally saved.

            More than one of your dependencies has a class that shares the same path and name. Figure out exactly which of those dependencies it is, and use an exclude group to omit it, e.g.

            Library class (from Android sdk) depends on program class (again, Android sdk)
            Asked 2018-Feb-04 at 10:20

            We are migrating from Android Gradle plugin 2.3.3 to Gradle plugin 3.0.1. Our application consists of an Application module and a Library module. Several dependencies are transitive (connected using api keyword) but even making them non-transitive using implementation doesn't help. After changing all the compile-type dependencies to the new ones, debug build works well. However, release build with Proguard shows thousands of warnings (on 2.3.3 everything goes well)

            In particular, I don't get why do we have such problems, when Android classes from library depend on Android classes from program (here are just few examples):
