诡异纪事file.exists()

代码中的文件明明是存在的但是打印的日志里却不存在

// 测试
SportHealth sportHealth = new SportHealth();
sportHealth.setFileType(0);
sportHealth.setName("201709071338156");
String filePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/bleFile/201709071338156.txt";
File upFile = new File(filePath);
File newUpFile = new File(filePath + ".zip");
// upFile.renameTo(newUpFile);
Log.e("resulttt", upFile.exists() + "······" + upFile.getAbsolutePath() + "·········" + org.xutils.common.util.FileUtil.copy(upFile.getAbsolutePath(), newUpFile.getAbsolutePath()) + "··········测试上传睡眠文件" + newUpFile.getAbsolutePath() + "······" + newUpFile.exists());
new BusinessHelpWatch(MainService.this, getResponseListener(sportHealth, filePath)).uploadSleep(newUpFile);
