以前用2.2 访问 donet webService没有问题，到3.0上访问出现android.os.NetworkOnMainThreadException
找了些资料经过实践
view plain copy to clipboard print ? public void onCreate() { StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder() .detectDiskReads() .detectDiskWrites() .detectNetwork() // or .detectAll() for all detectable problems .penaltyLog() .build()); StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder() .detectLeakedSqlLiteObjects() .detectLeakedClosableObjects() .penaltyLog() .penaltyDeath() .build()); }
似乎是3.0在网络上做了更加严格的限制，更多的查询API上的StrictMode 类
java.net.Unknownhostexception
