Android 开发时遇到的两个模拟器问题

开发环境: windows 2008 R2 x64, JDK 7u10, ADT v21.0.1-543035

一.启动 Nexus 7 模拟器失败

模拟器启动出现如下错误:

Starting emulator for AVD 'nexus7'
Failed to allocate memory: 8
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

方法:用命令行启动,指定内存为 512M,默认1024M有问题

c:\xxx>emulator -avd nexus7 -memory 512

二.GUI 响应非常慢

模拟器启动出现如下错误:

Starting emulator for AVD 'nexus7'
emulator: ERROR: Could not load OpenGLES emulation library: Could not load DLL!
emulator: WARNING: Could not initialize OpenglES emulation, using software renderer.

界面操作,响应很慢

原因是未指定类库地址相关环境变量

方法:添加变量定义:LD_LIBRARY_PATH=/home/xxxx/devel/android-sdk-linux/tools/lib

为此,新建一个批处理来启动模拟器 em.bat,存放在sdk的tools目录下,如下:

setlocal
set LD_LIBRARY_PATH=K:\android\ide\adt-bundle-windows-x86_64\sdk\tools\lib
emulator.exe -avd nexus7 -memory 512 -gpu on

开发中,先用命令行启动模拟器,再在运行调试时,选择当前运行的AVD即可.
