降低android版本

在android程序中加这两句话：降低版本，android 3.0以上版本需要加

StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork().penaltyLog().build());
  StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectLeakedSqlLiteObjects().penaltyLog().penaltyDeath().build());

位置：Oncreat方法下面即可

例如：

public class TIDSDemoActivity extends Activity {
 //
 private EditText  mEditText_show = null;
 private Button   mBotton_serversocket = null;
 private Button  mButton_socket = null;
 private Socket   mSocket = null;
 private ServerSocket mServerSocket = null;
 private String   mString ="";
 private BufferedReader mBufferedReader = null;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  //降低版本
 /* StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork().penaltyLog().build());
  StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectLeakedSqlLiteObjects().penaltyLog().penaltyDeath().build());*/
  super.onCreate(savedInstanceState);
  this.setContentView(R.layout.main);
