[转载]httpClient.execute抛Connection to refused异常问题

在4.0之后android采用了严格模式：所以在你得activity创建的时候，在super.onCreate(savedInstanceState);后面加上这个
 StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
            .detectDiskReads()
            .detectDiskWrites()
            .detectAll()   // or .detectAll() for all detectable problems
            .penaltyLog()
            .build());
         StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
            .detectLeakedSqlLiteObjects()
            .detectLeakedClosableObjects()
            .penaltyLog()
            .penaltyDeath()
            .build());
