Android 3.0 访问donet webService 出现 android.os.NetworkOnMainThreadException错误！收藏

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 plaincopy to clipboardprint?

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
