I know this topic has been talked a lot but not in this meanings. I need to store the logs in a .txt file but I cannot use the log4j or any other class but android.util.log I have this solution but it is not the best. For have the same information than in: Log.i(TAG, "An INFO Message"); I have to write... 

ERROR = logLevel < 3;
WARNING = logLevel < 2;
INFO = logLevel < 1;
if (INFO){ 

    appendLog("LEVEL: I    TIME: "+java.util.GregorianCalendar.DAY_OF_MONTH +
                        "-"+ java.util.GregorianCalendar.MONTH +" "+GregorianCalendar.HOUR_OF_DAY +":"+GregorianCalendar.MINUTE +
                        ":"+GregorianCalendar.SECOND +"."+GregorianCalendar.MILLISECOND + "    PID: "+
                        android.os.Process.myPid()+ "    TID: "+android.os.Process.myTid()+ "    Application: com.example.myapplication"+
                        "    TAG:" +TAG+ "    TEXT: An INFO Message");
}

and then...

public void appendLog(String text) {        
    File logFile = new File("sdcard/log.txt"); 
    if (!logFile.exists()) { 
        try { 
            logFile.createNewFile(); 
        }catch (IOException e){ 
            e.printStackTrace(); 
      } 
   } 
   try { 
       BufferedWriter buf = new BufferedWriter(new FileWriter(logFile, true));  
       buf.append(text); 
       buf.newLine(); 
       buf.close(); 
   } catch (IOException e) { 
       e.printStackTrace(); 
   } 
}

Does anyone has a more elegant solution than this? Thank you for helping me.
