一个工具类。第一个用来将logcat保存到文件，第二个用来获得logcat字符串。

public class Logcat {    public final static String TAG = "VLC/Util/Logcat";    /**     * Writes the current app logcat to a file.     *     * @param filename The filename to save it as     * @throws IOException     */    public static void writeLogcat(String filename) throws IOException {        String[] args = { "logcat", "-v", "time", "-d" };        Process process = Runtime.getRuntime().exec(args);        InputStreamReader input = new InputStreamReader(process.getInputStream());        FileOutputStream fileStream;        try {            fileStream = new FileOutputStream(filename);        } catch( FileNotFoundException e) {            return;        }        OutputStreamWriter output = new OutputStreamWriter(fileStream);        BufferedReader br = new BufferedReader(input);        BufferedWriter bw = new BufferedWriter(output);        try {            String line;            while ((line = br.readLine()) != null) {                bw.write(line);                bw.newLine();            }        }catch(Exception e) {}        finally {            bw.close();            output.close();            br.close();            input.close();        }    }    /**     * Get the last 500 lines of the application logcat.     *     * @return the log string.     * @throws IOException     */    public static String getLogcat() throws IOException {        String[] args = { "logcat", "-v", "time", "-d", "-t", "500" };        Process process = Runtime.getRuntime().exec(args);        InputStreamReader input = new InputStreamReader(                process.getInputStream());        BufferedReader br = new BufferedReader(input);        StringBuilder log = new StringBuilder();        String line;        while ((line = br.readLine()) != null)            log.append(line + "\n");        br.close();        input.close();        return log.toString();    }}
