This is an example to read Logcat contents programmatically in Android.
Normal developers won’t need this, but still it is a good thing to know how to do it.
package pack.coderzheaven;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class ReadLogDemo 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) {
}
}
}

I have run the sample application. it runs successfully. but i use “locat -e” option instead of “logcat -d”. it does not print anything in the text view. i requested you to add the solution for it.
Thank you.
u need to add
in manifest file
Unfortunately, a cut and paste of this code does not work. The very first readLine() returns null and so it drops straight out the loop. I am guessing that because Murali got it working, there is something that needs to be done that has not been described in this post?
Sorry,a bit late but I resolved the null return from the readLine() call by adding the following line to my manifest file:
Hi,
If u r wondering, set your permission in android manifest xml page to
..
Please let me your solutions
No need to add any permissions.
