Your main Activity :

package com.get_Logs;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;

public class Get_LogsActivity extends Activity {
    private TextView textv;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        textv = (TextView)findViewById(R.id.textView1);

        getallLogs();
    }

    private void getallLogs() {
        // TODO Auto-generated method stub
        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+"\n");
            }

            File myFile = new File("/sdcard/mysdfile.doc");
            if (!myFile.exists()) {
                myFile.createNewFile();
            }

            Log.e("log---->", ""+log.toString());

            textv.setText(log.toString());

            FileOutputStream fOut = new FileOutputStream(myFile);
            OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut);
            myOutWriter.append(log.toString());
            myOutWriter.close();
            fOut.close();



        } catch (IOException e) {
            Log.d("D: error generate log -->", "" + e.getMessage().toString());
        }
    }
}

your main layout file:


 <?xml version="1.0" encoding="utf-8"?>  
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
      android:orientation="vertical" android:layout_width="fill_parent"  
      android:layout_height="fill_parent">  
      <ScrollView android:id="@+id/scrollView1"  
           android:layout_height="match_parent" android:layout_width="match_parent">  
           <LinearLayout android:id="@+id/linearLayout1"  
                android:layout_width="match_parent" android:layout_height="match_parent">  
                <TextView android:id="@+id/textView1" android:layout_height="match_parent"  
                     android:textAppearance="?android:attr/textAppearanceMedium"  
                     android:text="TextView" android:layout_width="match_parent"></TextView>  
           </LinearLayout>  
      </ScrollView>  
 </LinearLayout>  




your manifest file:


 <?xml version="1.0" encoding="utf-8"?>  
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"  
    package="com.get_Logs"  
    android:versionCode="1"  
    android:versionName="1.0">  
   <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="13"/>  
   <uses-permission android:name="android.permission.READ_LOGS"></uses-permission>  
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>  
   <application android:icon="@drawable/icon" android:label="@string/app_name">  
     <activity android:name=".Get_LogsActivity"  
          android:label="@string/app_name">  
       <intent-filter>  
         <action android:name="android.intent.action.MAIN" />  
         <category android:name="android.intent.category.LAUNCHER" />  
       </intent-filter>  
     </activity>  
   </application>  
 </manifest>
