1.pad 三代
//保存到的文件路径
final String filePath = Environment.getExternalStorageDirectory().getAbsolutePath();
保存路径是: 在pad点开资源管理器后 直接internal memory 下的 xsy
2.保存日志到文件代码记录:
/**
* @param msg 打印的日志消息
*/
public static void writerLog(String msg) {
//保存到的文件路径
final String filePath = Environment.getExternalStorageDirectory().getAbsolutePath();
FileWriter fw = null;
BufferedWriter bw = null;
try {
//创建文件夹
File dir = new File(filePath, "xsy");
if (!dir.exists()) {
dir.mkdir();
}
//创建文件
File file = new File(dir, "soundlevel.txt");
if (!file.exists()) {
file.createNewFile();
}
//写入日志文件
fw = new FileWriter(file, true);
bw = new BufferedWriter(fw);
Date now = new Date(System.currentTimeMillis());
String format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(now);
bw.write(format + " " + msg + "\n");
bw.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
if (bw != null) {
try {
bw.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
