I saw all the post in here and still I can\'t figure how do get difference between two android dates.

This is what I do:

long diff = date1.getTime()

If you use Kotlin language for Android development, you can use ExperimentalTime extension. To get difference in days you can use it like this:

@ExperimentalTime
fun daysDiff(c1: Calendar, c2: Calendar): Double {
    val diffInMillis = c1.timeInMillis - c2.timeInMillis
    return diffInMillis.milliseconds.inDays
}

or if you want to get results as integer:

@ExperimentalTime
fun daysDiff2(c1: Calendar, c2: Calendar): Int {
    val diffInMillis = c1.timeInMillis - c2.timeInMillis
    return diffInMillis.milliseconds.toInt(DurationUnit.DAYS)
}
