Wie getTimeInMillis morgen Zeit auf Android zu verwenden?

Question

Ich möchte morgen '04: 00 'Zeit verwenden getTimeInMillis();

und ich versuche dies.

String time1 = "23:00"; // I want get 2017-02-22 23:00 
String time2 = "04:00"; // I want get 2017-02-23 04:00 

String[] btime1 = time1.split(":"); 
String[] btime2 = time2.split(":"); 

Calendar ctime1 = Calendar.getInstance(); 
ctime1.set(Calendar.HOUR_OF_DAY, Integer.parseInt(btime1[0])); 
ctime1.set(Calendar.MINUTE, Integer.parseInt(btime1[1])); 

Calendar ctime2 = Calendar.getInstance(); 
ctime2.set(Calendar.HOUR_OF_DAY, Integer.parseInt(btime2[0])); 
ctime2.set(Calendar.MINUTE, Integer.parseInt(btime2[1])); 

Calendar curtime = Calendar.getInstance(); 

Log.d(TAG, "23:00 time --->" + ctime1.getTimeInMillis()); // 1487772017952 
Log.d(TAG, "04:00 time --->" + ctime2.getTimeInMillis()); // 1487703617952 
Log.d(TAG, "curtime --->" + curtime.getTimeInMillis()); // 1487724197952 --> curtime is 2017-02-22 09:44 

und ich überprüfen logcat ctime2.getTimeInMillis(); ist 2017-02-22 04:00 Zeit. aber ich will morgen 04:00 Zeit (2017-02-23 04:00)

how to get tommorow time ? 

@update 
and I try 
`ctime2.getTimeInMillis() + (24*60*60*1000);` --> 148770361795286400000

Calendar cal = Calendar.getInstance(); //current time (today) 
cal.set(Calendar.HOUR_OF_DAY, 4); //reset to 4 am (today) 
cal.set(Calendar.MINUTE, 0); 
cal.add(Calendar.DATE, 1); //add a day
