Reading logs programatically

Writing logs into logcat from yuor application is quite easy, reading the logcat programmatically is just a bit more tricky.
Reading logs is usually used for bugreport purposes.

The following code reads logs and displays then in a TextView:

public class LogTest extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    try {
      Process process = Runtime.getRuntime().exec("logcat -d");
      BufferedReader bufferedReader = new BufferedReader(
      new InputStreamReader(process.getInputStream()));
                       
      StringBuilder log=new StringBuilder();
      String line;
      while ((line = bufferedReader.readLine()) != null) {
        log.append(line);
      }
      TextView tv = (TextView)findViewById(R.id.textView1);
      tv.setText(log.toString());
    } catch (IOException e) {
    }
  }
}

When I first fint this solution, I was afraid that it will require some extreme permission because it runs logcat like a console command.
