Recently, when playing an app, found just entered his page, his page of the child controls are flying from the right side, feel good, the way to imitate a. It's much more comfortable to watch than to stay there!Still Feel good! Anyway, I think it's better than a stiff-looking! You guys think that!Looking at what we are imitating:Almost, just fine-tune it!The point code, in fact, is very simple:Create a new Anim folder to create a new two XMLJust put t

So don't be greedy to keep your service running in the background, which not only leads to lower performance for your app, it's also possible for users to discover t
to jump to the previous activity. Next, when jumping to the blank activity, call the System.GC () method to ensure that a GC operation is triggered. Finally, if the memory of the previous activity is all properly freed, there should be no object in the previous activity in the memory snapshot after the blank activity is started.About memory jitter and
bitmapsWhen you load a bitmap, you just need to keep the data that fits the current screen device resolution, and if the original is higher than your device resolution, you need to do a smaller action. Keep in mind that increasing the size of the bitmap will increase the memory by 2, because both X and Y are increasing.
Note: in Android 2.3.x (API level
occupied, if the class is a global variable (such as a static attribute in the class, global map, etc., there is a static reference or final always point to it). Then there is no corresponding removal mechanism, which is likely to cause the collection to increase in memory only. Workaround: When using the collection class, increase the deletion element mechanism

The MaxMemory () method gets the maximum memory that the system can allocate for the app, and TotalMemory () Gets the amount of memory heap space currently allocated by the app. I have two mobile phones, a oppo Find7, running the color O

In the case of Android, where the RAM is on top of the G, there's no need to worry too much about the app's consumption of Android memory, but what I do in the real world is the education of primary school App,app buttons, backgrounds, animation transformations ar
Let's start with a little analysis of the test environment: we know that CPU and memory consumption is a real-time change, and no specific Android app on the market can monitor CPU and memory consumption in real time and use log logs to save. Considering that Android's underlying framework is a Linux -based platform, w
1Java has garbage collection capabilities, programmers do not have to manually manage memory allocations, reduce the flash-back caused by segment errors, and reduce heap space bloat caused by memory leaks, making code more secure. However, there is still a possibility of memory leaks in Java, while Android us

As device hardware performance continues to improve, from the earliest 16M restrictions (G1 phones) to later 24m,32m,64m, all follow the Android framework's minimum memory size limit for each app, refer to http://source.android.com/ Compatibility/downloads.html 3.7 knots.View th

In Android development, how can we effectively detect memory usage and Memory leakage?
Three methods are introduced here:
1. Program Log information
During garbage collection, the program prints a Log information logcat window. For example:

using pictures in your app:1, the graph resources can not be randomly placed folder, it is best to follow the corresponding transduction to the corresponding file home, avoid because access to other files and resulting in the image of the memory increase.2, for only a set of graph resources, as far as possible to choose high-precision size cut. Refer to the devi

Because of the memory on the real machine now, 2G has rarely seen, basically all 8G look like. This

If an activity has implemented the life cycle method correctly, and has saved the current state, then the system kills these background processes to the user's visual effect, there is no impact, because when the user returns back, the activity has saved all the visual state;5.
