沒有檔案夾則建立檔案夾

File file = new File(PATH_LOGCAT);
      if (!file.exists()) {
          file.mkdirs();
          Log.e("wy","建立檔案夾1");
      }
      

private void init(Context context) {
      if (Environment.getExternalStorageState().equals(
              Environment.MEDIA_MOUNTED)) {// 優先儲存到SD卡中
          PATH_LOGCAT = Environment.getExternalStorageDirectory()
                  .getAbsolutePath()+File.separator + "leotech" + File.separator + "logs";
      } else {// 如果SD卡不存在，就儲存到本應用的目錄下
          PATH_LOGCAT = context.getFilesDir().getAbsolutePath()
                  + File.separator + "logs";
      }
      File file = new File(PATH_LOGCAT);
      if (!file.exists()) {
          file.mkdirs();
          Log.e("wy","建立檔案夾1");
      }
      Log.e("wy","路徑1"+PATH_LOGCAT);
  }
