Posted on 2015年9月24日 by allenmo

PHP

int SDK_INT = android.os.Build.VERSION.SDK_INT; //Log.v("kkk","SDK_INT:" + SDK_INT); if (SDK_INT > 8) { StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); //your codes here }

1 2 3 4 5 6 7 8

int SDK_INT = android.os.Build.VERSION.SDK_INT; //Log.v("kkk","SDK_INT:" + SDK_INT); if (SDK_INT > 8) {      StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();      StrictMode.setThreadPolicy(policy);      //your codes here }
