本文实例讲述了Android实现内存中数据保存到sdcard的方法。分享给大家供大家参考，具体如下：

public static void writeToSdCard(String s) { try { File dst = new File("/sdcard/test_sensor/" + mName + ".txt"); File parent = dst.getParentFile(); if(!parent.exists()) { parent.mkdirs(); } FileOutputStream outStream = new FileOutputStream(dst, true); OutputStreamWriter writer = new OutputStreamWriter(outStream, "gb2312"); writer.write(s); writer.write("n"); writer.flush(); writer.close();// 记得关闭 outStream.close(); } catch (Exception e) { Log.i("test result", "file write error"); e.printStackTrace(); } }

希望本文所述对大家Android程序设计有所帮助。
