Specify parameters when starting the simulator

During Android development, if you use a simulator to run a program, you can adjust the running of the simulator by specifying some parameters, such as the interface size of the simulator and the memory size allocated to the simulator during running.

At first, because I didn't allocate enough memory to the simulator, I often terminated abnormally when running the simulator.

The following sections describe how to set and create a virtual device in eclipse through the command line.

1. Specify emulator-AVD android2.2-scale 0.9-memory 256 when starting the simulator on the command line.

-AVD specifies the virtual device name,-scale specifies the interface size, and-memory 256 specifies the memory allocated to the simulator.

2. Specify the following when running the android project in Eclipse:

Choose run> RUN configurations> Target> emulator launch parameters to select the skin.
In the "Additional emulator command line options", you can enter-scale -- to zoom in the simulator window. Fill in-memory 256 to specify the allocated memory.

3. When creating a virtual device, specify: In 'properties' -- "'new', select 'device Ram size', and fill in the value.

Other parameters are listed below:

-Sysdir <dir> is used to search the system hard disk image in the <dir> directory of the simulator.
