Android開發調試技巧

Android開發過程中會遇到不少需要調試的地方，常用的調試也很簡單，這裏總結一些不是很常規的調試技巧（持續更新）

1、寫本地日誌

利用BufferWriter類來實現，不多說廢話，直接上代碼，這個後面方便傳代碼到git的時候，放到git上吧，畢竟直接放博客排版太長了

public class LogsUtil {
    public static LogsUtil logsUtil = new LogsUtil();
    private File logFile;
    private static final String TAG = "LogsUtil";
    private LogsUtil(){
    }

    public static LogsUtil getInstance(){
        return logsUtil;
    }

	//please call this init function before use
    public void init(Context context,String fileName){
        logFile = new File(context.getExternalCacheDir(),fileName);
        if(!logFile.exists()){
            try{
                logFile.createNewFile();
            }catch (IOException e){
                Log.d(TAG,"init" + e.getMessage());
            }
        }
    }

    public void saveLog(String info){
        try{
            BufferedWriter bufferedWriter = new BufferedWriter(new FileWriter(logFile,true));
            bufferedWriter.write(info);
            bufferedWriter.newLine();
            bufferedWriter.flush();
            bufferedWriter.close();
        }catch (IOException e){
            Log.d(TAG,"saveLog" +  e.getMessage());
        }
    }

    public void readLog(){
        try{
            BufferedReader bufferedReader = new BufferedReader(new FileReader(logFile));
            String line = bufferedReader.readLine();
            StringBuilder stringBuilder = new StringBuilder();
            while(line != null){
                stringBuilder.append(line);
                stringBuilder.append("\n");
                line = bufferedReader.readLine();
            }
            bufferedReader.close();
            Log.d(TAG,"readLog: \n" + stringBuilder.toString());
        }catch (IOException e){
            Log.d(TAG,"readLog " + e.getMessage());
        }
    }
}

2、獲取本地存儲的xml以及db文件
