将assets or raw folder资料复制到sd卡

将assets or raw folder文件复制到sd卡

有时候我们需要把程序的raw文件放在sd卡中，其实有时候这样做可以释放资源，有时候可能是使坏呼呼

void copyAssets() {     String[] files;     try     {         files = this.getResources().getAssets().list("");     }     catch (IOException e1)     {         return;     }      if(!mWorkingPath.exists())     {         if(!mWorkingPath.mkdirs())         {             new AlertDialog.Builder(this)                 .setTitle(R.string.ERROR)                 .setMessage(R.string.FAILED_DIR_CREATE)                 .setPositiveButton(android.R.string.ok, new OnClickListener(){                     @Override                     public void onClick(DialogInterface dialog, int which)                     {                         dialog.dismiss();                     }                 })                 .create()                 .show();         }     }      for(int i = 0; i < files.length; i++)     {         try         {             String fileName = files[i];              if(fileName.compareTo("images") == 0 ||                fileName.compareTo("sounds") == 0 ||                fileName.compareTo("webkit") == 0)             {                 continue;             }              File outFile = new File(mWorkingPath, fileName);             if(outFile.exists()) continue;              InputStream in = getAssets().open(fileName);             OutputStream out = new FileOutputStream(outFile);              // Transfer bytes from in to out             byte[] buf = new byte[1024];             int len;             while ((len = in.read(buf)) > 0)             {                 out.write(buf, 0, len);             }              in.close();             out.close();         }         catch (FileNotFoundException e)         {             e.printStackTrace();         }         catch (IOException e)         {             e.printStackTrace();         }     }
