I have a CountdownTimer that counts down from 60 seconds. This CountdownTimer works by setting a textView to the remaining milliseconds, but whenever i rotate my device, the CountdownTimer gets reset.
I know this happens because the Activity gets restarted on rotation. So i tried saving the time remaining in a bundle and then restoring it, after the Activity was restarted.
long transferValue;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_playtimemode);
Log.d("Debug", "onCreate: " + transferValue);
long setTime = 60000;
long difference = setTime - transferValue;
new CountDownTimer(difference, 1000) {
public void onTick(long millisUntilFinished) {
millisUntilFinishedToSave = millisUntilFinished;
tvCountdown.setText("" + millisUntilFinished / 1000);
}
public void onFinish() {
tvCountdown.setText("done!");
}
}.start();
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putLong("millisKey", millisUntilFinishedToSave);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
transferValue = savedInstanceState.getLong("millisKey");
Log.d("Debug", "onRestoreInstanceState(): " + transferValue);
}
This however doesn't work. I am intializing transferValue at the top of this code (hence it returning 0), but how can i else save the data from the savedInstanceState to the CountdownTimer?
