Create a virtual machineAfter installing Eclipse+adt and setting up the Android SDK path, click the button in the diagram or select the appropriate option in the menu to open the AVD Manager (Android virtual Device Manager). Click the New button Fill in the name, memory card size, select the screen size, click Create AVD. Startup of virtual mach

machine or a single process. Android apps have a standalone virtual machine, which opens a separate virtual machine for each application (so the design will not crash the entire system in the event of a single program crash).Note: When Heapgrowthlimit is set, a single process can have a maximum memory value of Heapgrowthlimit. In Android development, if you want

Android 5.0 frequent reboot in late application Many users report that the application in Android 5.0 appears to restart frequently in the background, and that if the device is not restarted for a long time, the performance of the system and the application will be significantly reduced and the response begins to slow. Android's background management mechanism has been quite criticized, although the

objectsObject creation is never free. Creating an object is never free. The generational GC (with per-thread allocation pools) can make the allocation of temporary objects cheaper, but it is always more expensive to perform allocated memory than to perform allocation operations. As you assign more objects to the app, you may need to force the GC, and the GC operation will be a bit of a lag for the user exp

Android allocates a certain amount of memory to each app. The size of this memory is not the same between different phones. If your app uses memory that reaches the allocated size, it is caused when the

larger packets from the network. But don't let users wait without meaning. To make them feel that the task is being carried out. Add a "select" or "Push" state to the key, and you can add a rotation symbol when the load time is short, and you can use a progress bar for a longer load time. However, never let the user face the empty screen.Waiting is always distressing. At least let users know how long they need to wait.(TheGoogle Reader app displays a

tools, the following is how to use the above two points for memory leak detection. But to tell the truth, I did not use the very skilled, but in the process of doing the project, groping out a little bit of conversation, let's share here. Later, if there is a new understanding in this respect, later, and then to share with you.When I use the code and tools above, I find that the console often outputs a bit of information:That is, an activity was crea

Refer to the DNS configuration above for the same operation. This is almost the case. The last thing to note is to clear the cache on the mobile phone. You must close the browser and application, clear the memory, and enable it again. Otherwise, the DNS and net

The android SDK contains a tool named zipalign that can be used to optimize the APK package. We know that APK is actually a zip compressed file. zipalign can make your application run faster. The principle is to increase the system resolution speed by formatting the sequence of binary files in the ZIP folder. Just like formatting the code before reading it, it makes it easier for us to understand its meanin

This rule is valid only for base types and string types.Do not declare the view control as static, because the View object references the Activity object, and the object itself cannot be destroyed when the activity exits, causing a memory overflow.3.

Android is an effective solution to the problem of memory leaks Android memory leak, I want to do the Android application when I encountered a headache, here is a good information I find on the Internet, examples of the solution to this problem Foreword: Recently in studyi

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

?? A common feature of embedded devices is that memory capacity is relatively limited. When running more than a certain number of programs, or involved in complex calculations, it is likely that there is not enough memory, resulting in a system lag. The Android system is no exception, and it also faces the dilemma of physical

Most because of the heavy workload, in general, we seldom care about memory, only know the task to complete. It is only when the UI is really found or the app is running down (1.1 cards) that memory optimization is considered. Or your big company is more concerned about how fluent your phone is, and how much memory you
