increase app memory android

As we all know, each Android application has a certain memory limit when running, generally 16 MB or 24 MB (depending on the platform ). Therefore, when developing applications, you must pay special attention to your memory usage. Generally, the most memory-consuming resources are images, audio files, video files, and

Use a simple drawing app to illustrate Android's graphics-processing class with its own view-defining application.For example, there is an app for users to draw and doodle at their own discretion.It's not so fancy here, it's only available in black and white. But it can change the thickness of the nib.Essentially the eraser here is a white brush, without using the brush's Setxfermode method, to get a bunch

If you want to make the most failed case on Google Play, the best secret is that the interface is extremely slow, consumes power, and consumes memory. Next, you will get negative comments from users, and your reputation will become bad. It is useless even if your applications are well designed and creative. Every problem that affects product efficiency, such as power consumption or memory usage, affects

Poor code that is common in Android (Java) and is prone to memory leakage 1 (1) The cursor is not closed during database query. 2 (2) when constructing the Adapter, the cached convertView 3 is not used (3) Call recycle () to release memory when the Bitmap object is not in use. 4 (4) Release object reference 4 (5) Other 5 Iii.

Gettoplevelresources method of Resourcesmanager, the idea of this method is that in Resourcesmanager, all resource objects are stored in Arraymap, First, according to the current request parameters to find resources, if found on the return, otherwise create a resource object into the Arraymap. One thing to explain is why there are multiple resource objects, because there may be multiple directories in the res that fit different devices, different resolutions, different system versions, and acco

As the Android platform continues to evolve, it is constantly improving. Some features may have been deprecated or replaced with better functionality. The core API has been revised (bug fix) and pe

The Dalvik Virtual Machine supports garbage collection, but this does not mean you don't have to worry about memory management. Pay special attention to the memory usage of mobile devices. The memory space on the mobile devices is limited. In this article, let's take a look at how some of the memory profiling tools in

Java Virtual machine run generally have a memory limit, beyond this limit, will be reported OutOfMemory. There is usually a memory leak at this time. Resolving a memory leak is a two-step process: Analyzing whether an application really has a memory leak and finding a memory

I mainly want to summarize the ideas about Android mobile app in the forum. I think they can be implemented or interesting, and they can be used if they are not creative in the future. I also hope to help you. If you have any good ideas, remember to comment and leave a spark of your thoughts !!!!! 1. Programming controls the short circuit of the cell phone battery and turns it into a grenade. in case of dan

First, the Android side of the lagThe Android app is prone to lag during specific use, such as having a meal when viewing a page, a slow response after switching tabs, or a slow operation when it comes to sliding.Second, the reasons for the lagThere may be many reasons for the lag, such as:1. High CPU2. Memory Overflow

in the top list item will be recycled and then used to construct the bottom list item that appears. This construction process is completed by the getview () method, getview () the second view convertview parameter is the view object of the cached list item. (convertview is null if no view object is cached during initialization ). From this we can see that if we don't use convertview, but re-instantiate a view object in getview () every time, it will be a waste of resources and time, which will
