    new Thread(){
    public void run() {
    try {
    File file = new File(Environment.getExternalStorageDirectory(),"log.txt");
    FileOutputStream fos = new FileOutputStream(file);
    Process process = Runtime.getRuntime().exec("logcat");
    InputStream is = process.getInputStream();
    BufferedReader br = new BufferedReader(new InputStreamReader(is));
    String line;
    while((line = br.readLine())!=null){
    if(line.contains("I/ActivityManager")){
    fos.write(line.getBytes());
    fos.flush();
    }
    }
