Android team preferred DVM over JVM because of below given reasons.
1. Though JVM is free it was under GPU license, which is not good for Android as most of the Android is under Apache license.
2. JVM was designed by keep desktops in mind. So it is too heavy for embedded devices.
3. DVM takes less memory, runs; loads faster compared to JVM.
4. Since mobile devices have lot of limitations like low CPU speed and less Memory, it is always better not to use heavy components like JVM
