What about the lack of memory for Android phones? Method One: Install the RE manager, open to find the/data/local/directory, which has rights and TMP two folders, if there is no Rights folder, open the Tmp folder, here are all the software failed to install before, and then empty it. Method Two: Open the "RE Manager"--find "data"-"Dalvik-cache" in this folder are all the system cache files and un

best way to limit service life is to use intentservice, primarily because it starts when a intent is captured and kills itself when a task is executed. For more information, please read running in a Background Service.The most serious error in Android memory management is that you no longer need services that are still in the running state. So, don't let your se

The principle of Android memory management--process managementAndroid takes a different process management strategy from Linux , and unlike Linux, which ends the process after the process activity has stopped, Android keeps the processes in

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

People who have used Android phones will feel a doubt, open the task manager, a series of processes. You may feel that you have clearly appliedProgramAll quit. Why does the process always exist? Why does the application process that has never been used suddenly emerge? Why is the memory remaining in the system always very small? Is the memory insufficient? In fa

Occasionally to dump some of the phone's memory, CPU information, see for themselves or to provide information to Rd, so for Android some basic adb command or familiar.

1. Convert the image into a thumbnail and load it again: The Code is as follows:1 BitmapFactory. Options options = new BitmapFactory. Options ();2 options. inSampleSize = 2;3 Bitmap img = BitmapFactory. decodeFile ("/sdcard/1.png", options ); This code is used to read the thumbnail of 1.png. The length and width are only 1/2 of the original image. The image size is reduced, and the memory occupied is naturally reduced. The disadvantage of this is that
