Access LOGCAT DATA in your ANDROID application Progrmatically.

AIM: 
To read the LOGCAT data in your application which is very helpful  for bugreport purposes and for trobleshooting the device issues from remote location.


Solution:

You can check LOGCAT API documentation at  developer site.

Writing program to use that API and to print your logcat data in a Scrollable TextView.

1)
     public class ReadLogCat extends Activity {
      @Override
      public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        try {
          Process process = Runtime.getRuntime().exec("logcat -v");// Verbose filter
/*  Check diffrent filters available at http://developer.android.com/guide/developing/tools/logcat.html , Options section */

          BufferedReader bufferedReader = new BufferedReader(
          new InputStreamReader(process.getInputStream()));
                          
          StringBuilder logString=new StringBuilder();
          String line;
          while ((line = bufferedReader.readLine()) != null) {
            logString.append(line);
          }
          TextView tv = (TextView)findViewById(R.id.logTextView);
          tv.setText(logString.toString());
        } catch (IOException e) {
        }
      }
    }

2) To perform this operation we need to set Permissions in AndroidManifest.xml file as 

<uses-permission android:name="android.permission.READ_LOGS" />
