碩士 === 大同大學 === 通訊工程研究所 === 102 === The boot time is the biggest problem of Android,as Android system itself has a lot of services to support the applications and it could make boot time slower. Now days Android’s system is more widely to support the mobile devices, these are high-frequency switching machines.So the boot time of Android (ex. TV, handheld game consoles, digital radios, automotive telematics device and DVD players etc ) is an important factor for customers.To reduce the boot time of Android we have to improved the process of Android ( Linux kernel, file system mount, zygote process and scanning software packages) which part takes most time(zygote’s preload-classes time).In this thesis,the important of improving preload-classes of zygote process and removing unnecessary APK for some special products are proposed to reduce the boot time and enlarge RAM memory space. Based on the above propsol,in simulation of the telematics devices boot time is improved from 63.7 seconds to 22.9 seconds.It is indeed significantly improved.
