版本1.3.0：
我的多实例代码：
logPath = getExternalCacheDir().getPath() + "/logsample/xlog";
xlog2 = new Xlog();
xlogInstance2 = xlog2.openLogInstance(Xlog.LEVEL_DEBUG, Xlog.AppednerModeSync, "", logPath, "LOGSAMPLE2", 0);
xlog2.setConsoleLogOpen(xlogInstance2, true);
xlog2.appenderOpen(Xlog.LEVEL_DEBUG, Xlog.AppednerModeSync, "", logPath, "LOGSAMPLE2", 0);

logPath1 = getExternalCacheDir().getPath() + "/logsample/xlog1";
    xlog1 = new Xlog();
    xlogInstance1 = xlog1.openLogInstance(Xlog.LEVEL_DEBUG, Xlog.AppednerModeSync, "", logPath1, "LOGSAMPLE1", 0);
    xlog1.setConsoleLogOpen(xlogInstance1, true);
    xlog1.appenderOpen(Xlog.LEVEL_DEBUG, Xlog.AppednerModeSync, "", logPath1, "LOGSAMPLE1", 0);

    xlog2.logD(
            xlogInstance2,
            "testxlog",
            logPath,
            "111",
            2,
            android.os.Process.myPid(),
            Thread.currentThread().getId(),
            Thread.currentThread().getId()
            , "aaaaaaaaaaaaaaaaaaaaaaaaaaa22222222222222222"
    );

    xlog1.logI(
            xlogInstance1,
            "testxlog1",
            logPath1,
            "1111",
            2,
            android.os.Process.myPid(),
            Thread.currentThread().getId(),
            Thread.currentThread().getId(),
            "bbbbbbbbbbbbbbbbbbbbbbbbbbbb1111111111111111111"
    );

存在的问题：
1.AppednerModeSync模式下最后一行log无法写入文件；
2.AppednerModeAsync模式下解密报错：
error: Error -3 while decompressing: invalid block type
Traceback (most recent call last):
File "decode_mars_nocrypt_log_file.py", line 124, in DecodeBuffer
tmpbuffer = decompressor.decompress(str(tmpbuffer))
