The DVM executes Dalvik bytecode, which is compiled from programs written in the Java language. Note that the DVM is not a JVM. One of the key design principles of the DVM is that it should run on low memory mobile devices and loads quicker compared to any JVM.
Why do we have to use DVM instead of JVM in Android?
One of the main reasons of using DVM in android is because it follows the register based model and it is much faster than stack based model while JVM follows the stack based model which takes a lot of memory and also slower than DVM.

Can Android run JVM?
While most Android applications are written in Java-like language, there are some differences between the Java API and the Android API, and Android does not run Java bytecode by a traditional Java virtual machine (JVM), but instead by a Dalvik virtual machine in older versions of Android, and an Android Runtime (ART) …
