打印内容

读取的文件String:
{
  "platformName": "Android",
  "platformVersion": "6.0.1",
  "deviceName": "127.0.0.1:7555",
  "appPackage": "com.baidu.tieba",
  "appActivity": ".tblauncher.MainTabActivity",
  "noReset": true,
  "unicodeKeyboard": true,
  "resetKeyboard": true
}

转换为JSONString:
{"appPackage":"com.baidu.tieba","appActivity":".tblauncher.MainTabActivity","noReset":true,"platformVersion":"6.0.1","unicodeKeyboard":true,"platformName":"Android","deviceName":"127.0.0.1:7555","resetKeyboard":true}
转义后的JSONString:
{\"appPackage\":\"com.baidu.tieba\",\"appActivity\":\".tblauncher.MainTabActivity\",\"noReset\":true,\"platformVersion\":\"6.0.1\",\"unicodeKeyboard\":true,\"platformName\":\"Android\",\"deviceName\":\"127.0.0.1:7555\",\"resetKeyboard\":true}
反转义后的JSONString:
{"appPackage":"com.baidu.tieba","appActivity":".tblauncher.MainTabActivity","noReset":true,"platformVersion":"6.0.1","unicodeKeyboard":true,"platformName":"Android","deviceName":"127.0.0.1:7555","resetKeyboard":true}
