title: How to save logs to file filterwise?
body: <p>Is it possible to get only the app specific logs not all the logs that the device is producing using some filters or so?</p>
  
  <p>i have tried this,</p>
  
  <p><code>Runtime.getRuntime().exec("logcat -f " + Environment.getExternalStorageDirectory()+"/KeysersData/LogData.log");</code></p>
  
  <p>i want to save specific tag related data.</p>
