手工新建Android AVD的方法

有时候运行android程序时会提示：No compatible targets were found Do you wish to a add new Android Virtual Device！
这时可手工建立一个AVD。
首先看看有哪些可用的target:
[root@seuzw seuzw]# android list targets

Available Android targets:
id: 1 or "android-5"
     Name: Android 2.0
     Type: Platform
     API level: 5
     Revision: 1
     Skins: HVGA (default), WQVGA432, WQVGA400, WVGA854, QVGA, WVGA800
id: 2 or "Google Inc.:Google APIs:5"
     Name: Google APIs
     Type: Add-On
     Vendor: Google Inc.
     Revision: 1
     Description: Android + Google APIs
     Based on Android 2.0 (API level 5)
     Libraries:
      * com.google.android.maps (maps.jar)
          API for Google Maps
     Skins: WVGA854, WQVGA400, HVGA (default), WQVGA432, WVGA800, QVGA

然后输入如下命令新建一个AVD：
[root@seuzw seuzw]# android create avd --name aid20r1 --target 1
