嘿是否有可能在Android的收集从一个类的所有Log.d，不断追加并将其保存到SD卡？

例如：

 类的Andr​​oid {

    私人最终静态字符串变量=你好;

    公共无效ABCD（）{
    Log.d（TAG，它进入ABCD法）;
    }

    公共无效EFGH（）{
    Log.d（TAG，它走进EFGH法）;
    }

       / *这里收集上述所有日志和写入SD卡*提交/

}
 

解决方案

您可以使用的logcat 命令所有日志。您可以尝试这样的：

 公共静态无效PRINTLOG（上下文的背景下）{
    字符串文件名= context.getExternalFilesDir（空）.getPath（）+文件分割符+my_app.log;
    字符串命令=logcat的-d *：V;

    Log.d（TAG，命令：+指令）;

    尝试{
        。工艺过程=调用Runtime.getRuntime（）EXEC（命令）;

        的BufferedReader在=新的BufferedReader（新的InputStreamReader（process.getInputStream（）））;
        串线= NULL;
        尝试{
            档案文件=新的文件（文件名）;
            file.createNewFile（）;
            FileWriter的作家=新的FileWriter（文件）;
            而（（行= in.readLine（））！= NULL）{
                writer.write（行+\ N）;
            }
            writer.flush（）;
            writer.close（）;
        }
        赶上（IOException异常E）{
            e.printStackTrace（）;
        }
    }
    赶上（IOException异常E）{
        e.printStackTrace（）;
    }
}

Hey is it possible in Android to collect all Log.d from one class and keep on appending it and save it into SDCard ?

For example :

Class Android {

    private final static String TAG = "hello";

    public void abcd(){
    Log.d(TAG, "it went into abcd method");
    }

    public void efgh(){
    Log.d(TAG, "it went into efgh method");
    }

       /*Here collect all above LOGS and write to file in SDCard*/

}

You can get all logs with the logcat command. You can try something like:

public static void printLog(Context context){
    String filename = context.getExternalFilesDir(null).getPath() + File.separator + "my_app.log";
    String command = "logcat -d *:V";

    Log.d(TAG, "command: " + command);

    try{
        Process process = Runtime.getRuntime().exec(command);

        BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = null;
        try{
            File file = new File(filename);
            file.createNewFile();
            FileWriter writer = new FileWriter(file);
            while((line = in.readLine()) != null){
                writer.write(line + "\n");
            }
            writer.flush();
            writer.close();
        }
        catch(IOException e){
            e.printStackTrace();
        }
    }
    catch(IOException e){
        e.printStackTrace();
    }
}
