android - 是否为每个应用程序创建了一个 Dalvik 虚拟机实例？

Question

是为每个应用创建一个 Dalvik 虚拟机实例，还是所有 Android 应用共享同一个 Dalvik 虚拟机实例？

Answer 1

来自开发者文档:

Every Android application runs in its own process, with its own instance of the Dalvik virtual machine. Dalvik has been written so that a device can run multiple VMs efficiently.

The Dalvik VM executes files in the Dalvik Executable (.dex) format which is optimised for minimal memory footprint.

The VM is register-based, and runs classes compiled by a Java language compiler that have been transformed into the .dex format by the included dx tool.
