1. eclipse的Device中不显示手机
在eclipse中连接不上手机,出现adb server didn't ACK fail to start daemon 错误.
出现这种原因是因为adb所使用的5037端口被占用了.
使用adb kill-server 关闭adb服务 , 使用adb start-server开启adb命令 ; 如果5037端口被占用则会出现启动失败, 报出上述错误;
查看哪些进程占用了端口 : netstat -ano | findstr "5037" 会出现下面的结果
G:\Documents and Settings\Administrator>netstat -ano | findstr "5037"
TCP 127.0.0.1:1939 127.0.0.1:5037 ESTABLISHED 5748
TCP 127.0.0.1:1978 127.0.0.1:5037 ESTABLISHED 3000
TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 5748
TCP 127.0.0.1:5037 127.0.0.1:1939 ESTABLISHED 5748
TCP 127.0.0.1:5037 127.0.0.1:1977 CLOSE_WAIT 5748
TCP 127.0.0.1:5037 127.0.0.1:1978 ESTABLISHED 5748
可以看到 5748 3000 两个进程占用了5037端口.
打开进程管理器, 点击查看,选择列,将PID进程标示符勾选上,然后根据pid终止相应的进程.
这两个进程分别是豌豆荚 和 QQ , 同时将adb.exe 和 tadb.exe 进程干掉.
此时执行 adb start-server 命令即可启动adb服务 , 之后启动就会启动成功.

开发中遇到了上述错误 , 后来发现是 使用了TraceView导致的
不知道在代码的什么地方添加了TraceView的相关代码 , 去掉之后 , 就好了
我在Activity中的onCreate()方法中添加了 :
Debug.startMethodTracing();
在onDestroy()方法中添加了 :
Debug.stopMethodTracing();
去掉了上述两行代码 , 就不会出现上述错误了 ;
3. Call requires API level 8 (current min is 1)错误
导入了一个程序 , 每次运行之后都会出现该错误 .
点击clean 错误就会消失 , 但是执行该错误的时候该错误就会重新出现 .
这个错误需要在AndroidManifest.xml配置文件中修改 user-sdk 标签
给user-sdk 添加一个android:minSdkVersion="8" 属性
4. 奇怪的空指针异常
今天出现一个奇怪的错误, 很简单空指针异常, 我只负责编码, 不管编译, 然后上传到SVN上, 结果出了下面的错误 , 看了半天 , 木有看懂 :
11-13 10:39:53.337: E/AndroidRuntime(11030): FATAL EXCEPTION: Thread-394 11-13 10:39:53.337: E/AndroidRuntime(11030): java.lang.NullPointerException 11-13 10:39:53.337: E/AndroidRuntime(11030): at com.ivt.mHealth.widget.aa.b(Unknown Source) 11-13 10:39:53.337: E/AndroidRuntime(11030): at com.ivt.mHealth.widget.DisplaySurfaceView.a(Unknown Source) 11-13 10:39:53.337: E/AndroidRuntime(11030): at com.ivt.mHealth.widget.ae.run(Unknown Source)
我一看 蒙了 , 这是什么错误 , 没定义过这个类啊 , 后来才想起来 这是代码混淆以后的效果 .
有点无语 ... 想了半小时才反应过来
我直接从SVN上down了一下代码, 重新编译下 , ╮(╯▽╰)╭ 拨云见日
11-13 10:41:57.432: E/AndroidRuntime(11507): FATAL EXCEPTION: Thread-398 11-13 10:41:57.432: E/AndroidRuntime(11507): java.lang.NullPointerException 11-13 10:41:57.432: E/AndroidRuntime(11507): at com.ivt.mHealth.widget.BpmSurface.drawMpmBpm(BpmSurface.java:169) 11-13 10:41:57.432: E/AndroidRuntime(11507): at com.ivt.mHealth.widget.BpmSurface.drawToSurfaceView(BpmSurface.java:109) 11-13 10:41:57.432: E/AndroidRuntime(11507): at com.ivt.mHealth.widget.DisplaySurfaceView.drawToSurface(DisplaySurfaceView.java:183) 11-13 10:41:57.432: E/AndroidRuntime(11507): at com.ivt.mHealth.widget.DisplaySurfaceView.access$1(DisplaySurfaceView.java:178) 11-13 10:41:57.432: E/AndroidRuntime(11507): at com.ivt.mHealth.widget.DisplaySurfaceView$RenderThread.run(DisplaySurfaceView.java:144)
以后千万不要看编译出来的产品的log , 都是混效过的 ........
这是少上传了一行代码到SVN上啊 ...... 泪奔 .... 半小时就这么浪费了
