新手求教android4.0以后上不了网

Question

4.0以后都要求异步加载网络，不过也简单的方法，你可以在oncreate后面加StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()        
        .detectDiskReads()        
        .detectDiskWrites()        
        .detectNetwork()   // or .detectAll() for all detectable problems        
        .penaltyLog()        
        .build());        
        StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()        
        .detectLeakedSqlLiteObjects()     
        .penaltyLog()        
        .penaltyDeath()        
        .build());
