I have been using " public boolean setLastModified (long time) " for setting the file modified time but it always return false. I have seen few similar posts related to this but none of them could work for me. can someone give me solution for this?

Please do not post me any URL's, I have already seen them :

file.lastModified() is never what was set with file.setLastModified()

Is it possible to reset the last modified date of an Android file?

setLastModified()在 Android 上显然不可靠，可能在某些设备上工作而不在其他设备上工作。

您被告知要测试返回值，如果失败则返回 false。失望地发现这...
