在 onCreate 重载里添加如下代码:

 

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());
