3.PANIC: Could not find *.ini file in $ANDROID_AVD_HOME nor in $HOME/.android/avd​

重启电脑好了

5.You cannot combine custom titles with other title features

标题设置了两遍，tab中设置过，页面不再次设置

6.Should have subtitle controller already set

同一个控件的属性定义了两次

7.Attempt to invoke virtual method 'boolean com.wh.facecollect.FaceCertActivity$MyHandler.sendEmptyMessage(int)' on a null object reference

Handler是类，使用其对象未进行实例化new，故空指针

8.adb server version (31) doesn't match this client (36); killing... 360手机助手占用此端口，将进程中的360Mobile开头的删掉。http://blog.csdn.net/rodulf/article/details/51939974

 8.启动模拟器报错，The connection to adb is down, and a severe error has occured.关闭所有的adb进程，重启eclipse即可。

9.Android中MediaRecorder.stop()报错 java.lang.RuntimeException: stop failed. 是因为抛出异常，捕获即可

10.Didn't find class "ImageSize" on path: DexPathList[[zip file "/data/app/com.wh.imageloader-1/base.apk"]

有些android，需要一些第三方的包，直接将其引入，在以前是可以的，但是在最新的adt中不行，必须在程序中新建一个libs文件夹，将第三方的jar文件copy到libs文件夹中才行。在Java Build Path面板下的Order and Export中，要把你引入的jar文件勾上

11. ImageLoader must be init with configuration before using，使用前要先初始化

imageLoader.init(ImageLoaderConfiguration.createDefault(this));
