Problem
I'm Trying to Write Logs to Custom Log.txt File on Android File using this code of Mine but then this method creates file but contains nothing. Basically I want to read previous contents of the file and then append my data with the existing content. The Code is as follows : ``` public static void write(String str) { InputStream fileInputStream = null; FileOutputStream fileOutpurStream = null; try { fileInputStream = new FileInputStream(file); fileOutpurStream = new FileOutputStream(file); if(file.exists()) { int ch = 0; int current = 0; StringBuffer buffer = new StringBuffer(); while((ch = fileInputStream.read()) != -1) { buffer.append((char) ch); current++; } byte data[]=new byte[(int)file.length()]; fileInputStream.read(data); fileOutpurStream.write(data); fileOutpurStream.write(str.getBytes(),0,str.getBytes().length); fileOutpurStream.flush(); } else { file.createNewFile(); fileOutpurStream.write(str.getBytes(),0,str.getBytes().length); fileOutpurStream.flush(); } } catch(Exception e) { e.printStackTrace(); } finally { try { fileInputStream.close(); fileOutpurStream.flush(); fileOutpurStream.close(); fileOutpurStream = null; fileInputStream = null; } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } ```
