In the Android mobile applications, transferring pictures is the main reason that users consume their network data flow.Although efficient image compression method is an effective way to solve the problem, the image compression method does not be extensively studied on the Android platform.In order to achieve the purpose of quickly and efficiently compressing images in developing Android mobile application, we pre-process image with Android API before compressing image, and accomplish the processing of the pretreatment image's color conversion, FDCT transform, quantization, coding and other operations to achieve the processing of JPEG image compression encoding under the Android platform.The experimental results show that the method can efficiently compress images, and guarantee higher compression ratio and good image quality.
