Android: 运行android avd时，可能出现的错误

rzzhang@rzzhang-desktop:~/workspace$ ./out/host/linux-x86/bin/android avd
Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM

查看java版本：

rzzhang@rzzhang-desktop:~/workspace$ java -version
java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)

重新设置ANDROID_SWT

rzzhang@rzzhang-desktop:~/workspace$ export ANDROID_SWT=prebuilt/linux-x86_64/swt/

再次启动AVD

在安装安卓SDK模拟器中，出现错误提示：A target must be selected in order to create an AVD。

错误原因是没有完整的SDK。

因此从Source Tree中build对应版本的SDK。

rzzhang@rzzhang-desktop:~/workspace$ make sdk

make: *** [out/host/linux-x86/sdk/android-sdk_eng.rzzhang_linux-x86.zip] 错误 44

错误原因时没有正确地配置编译选项，编译SDK的正确方法：

rzzhang@rzzhang-desktop:~/workspace$ source build/envsetup.sh

rzzhang@rzzhang-desktop:~/workspace$ lunch sdk-eng

rzzhang@rzzhang-desktop:~/workspace$ make sdk

再次启动模拟器管理器：

rzzhang@rzzhang-desktop:~/workspace$ ./out/host/linux-x86/sdk/android-sdk_eng.rzzhang_linux-x86/tools/android avd

这次，可以正确地配置模拟器了。
