alguna extraña con SystemClock.getElapsedTime(), hice algunos cambios para la normalidad utilizando la fecha de inicio, como
myChron.setBase(startDate.getTime());
Aquí hijo del cronómetro a continuación, TimeView

Simplemente copia y el uso , funciona para mí
Sí, ya he visto eso y probado, pero el cronómetro no siempre obtienen resseted ... Se inicia a las 0:00 en cualquier momento! Ni siquiera puedo hacer que comience en un valor constante diferente a 0:00. – Santiago
¡¡Gran respuesta amigo !!! Muchas gracias !!!! – Arun
Gracias Macarse .... estaba buscando exactamente esto ... he pasado muchas horas en esto .... gracias amigo – shripal
