Graphical images are inevitably used in Android Application Development, which generates bitmap objects. If the bitmap object is not properly processed during development, the out of memory (OOM) exception is easily generated. The following are some

Android applications frequently process images. Especially when a program loads a large number of images and high-resolution images, oom exceptions are most likely to occur. Below are some of my memory loading methods. Method 1: public Bitmap

Caching bitmaps [cache bitmap] Loading a single bitmap to the UI is simple and straightforward. However, if you need to load a large number of images at a time, it will become complicated. In most cases (for

Author: banyao2006   Compared with single-core processors, multi-core processors face great challenges in architecture, software, power consumption, and security design, but they also have great potential. Like SMT, CMP is committed to exploring

The stream playback data source is from the isource interface object, which can be from the network, memory, or file. Streaming media has two types of content: one is a tabular media with the header, the starting position of the original data, such

For textfield objects, use the appendtext () method instead of the + = Operator. When using the text attribute of the textfield class, use the appendtext () method instead of the + = Operator. The appendtext () method can improve the performance.For
