如何在android设备上获取csv/txt文件中的特定日志
我想将日志以csv/txt文件的形式发送到我的设备。问题是我只需要一个活动的特定日志。下面是我想要获取日志的代码如何在android设备上获取csv/txt文件中的特定日志,android,logging,export-to-csv,java.util.logging,Android,Logging,Export To Csv,Java.util.logging,我想将日志以csv/txt文件的形式发送到我的设备。问题是我只需要一个活动的特定日志。下面是我想要获取日志的代码 final Beacon maxBeacon = Collections.max(beacons, new Comparator<Beacon>() { public int compare(Beacon b1, Beacon b2) { return Integer.compare(b1.getRssi(),
final Beacon maxBeacon = Collections.max(beacons, new Comparator<Beacon>() {
public int compare(Beacon b1, Beacon b2) {
return Integer.compare(b1.getRssi(), b2.getRssi());
}
});
WifiManager manager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
WifiInfo info = manager.getConnectionInfo();
String address = info.getMacAddress();
String Bmacstring = String.valueOf(maxBeacon.getMacAddress());
String newString = Bmacstring.replace("[", "");
newString = newString.replace("[", "");
newString = newString.replace("]", "");
String query = "?deviceMacAddress=" + info.getMacAddress() + "&beaconMacAddress=" + newString;
Log.i("Rss", String.valueOf(maxBeacon));
new HttpAsyncTask().execute("http://192.168.137.121:1010/api/History/CreatHistory" + query);
final Beacon maxBeacon=Collections.max（beacons，新比较器（）{
公共整数比较（信标b1、信标b2）{
返回整数.compare（b1.getRssi（），b2.getRssi（））；
}
});
WifiManager=（WifiManager）context.getSystemService（context.WIFI_服务）；
WifiInfo=manager.getConnectionInfo（）；
字符串地址=info.getMacAddress（）；
String Bmacstring=String.valueOf（maxBeacon.getMacAddress（））；
String newString=Bmacstring.replace（“[”，”）；
newString=newString.replace（“[”，”）；
newString=newString.replace（“]”，“”）；
字符串查询=“？deviceMacAddress=“+info.getMacAddress（）+”&beaconMacAddress=“+newString；
Log.i（“Rss”，String.valueOf（maxBeacon））；
新建HttpAsyncTask（）。执行（“http://192.168.137.121:1010/api/History/CreatHistory“+查询）；
任何帮助都将不胜感激。在我创建日志帮助器类之前，有时会感谢您将日志存储在文本文件中

你为什么不写一个代码来将文本存储到文件中。恐怕我不知道。你能告诉我怎么做吗！！@Harsh Mittal你可以根据你的需要修改写入方法。我已经按照上面提到的那样做了，但我没有得到任何文件！！只是像以前一样登录logcat。我哪里出错了？你在清单中指定了权限吗？你正在测试吗棉花糖设备？我正在测试棒棒糖设备。我的设备中没有存储卡，所以我可能无法在设备中获取文件。
Logger.i("Rss", String.valueOf(maxBeacon));
