clean ram memory android

A lot of friends have asked me how to write high-performance applications, how to avoid the application of oom, or when the program memory consumption is too high, how to troubleshoot. Indeed, a good application, not only to perform well, performance issues should also be handled just right. So I read a lot of high-performance programming recommendations from Android, so from this article I'm going to start

Here we only talk about the usage: Private Final Static floattarget_heap_utilization = 0.75f; vmruntime can be called during oncreate. getruntime (). settargetheaputilization (target_heap_utilization. You can also customize the size of the android heap memory. For some Android projects, the main cause of performance bottleneck is the

(Mood tag)About Memory Overflow issuesAbout the stack memory overflow problem, presumably we have encountered, not like long time no see, but inseparable, inadvertently will encounter I knocked on the code one day without encountering memory overflow, I wa

ConceptApplication development is inseparable from storage, storage is divided into network, memory, sdcard file storage and external SDCard2 file storage, development must pay attention to memory management to avoid oom, lag and other bad user experience, but also pay attention to the variable recovery, to avoid memory leaks. Here's a look at some basic terminol

programs in the Android system. In order to ensure that their app can have enough memory to run, developer will first request enough memory, increase the heapstartsize, heap allocation of the initial size, increase the memory ram consumption, the key is to elevate the permi

When you do an Android project, you find a problem: When the application exits, click "Settings" to view the application, and the interface shows you can click "Force off". I think the reason for this is that there are still open activity not being destroy, then debugging, and then found that the activity should be all destroy. But the result is that you can click "Force off". As a result of this problem I found a more serious problem, that is, afte

. . 1.2 . Memory leak caused by collection container object not cleanedwe usually add references to some objects to a collection container (such as ArrayList), and when we don't need the object, we don't clean up its references from the collection, so the collection gets bigger. If the set is static , the situation is even worse. 1.3. Context leaksThe so-calledContext Leaks, in fact, more refers toactivity
