Display elapse time for automated viewpager change

I have implemented an auto changing viewpager with fragments. What I want is to show elapse time for each fragment. I have implemented it using threads but not working as I expected. On each onPageSelected event, new thread is creating. I think thread are heavy weighted. I tried to interrupt the thread. But no luck. Is this ok or do we have any other way of implementing this?

Timer with Handler and SharedPreference

Nowdays I tried to make a timer by using handler and sharedpreferences.
Today I had a problem with sharedprefereces.
The problem is that it is okay to push start button and go to background and then restart this app, the app is working correctly.
But it is not okay if i try twice the pattern(push start button -> background -> app -> background -> app) , the textview which display the time turns to zero....
I don't know what is problem....
Here is the code..
private Button mStartBtn, mStopBtn, mRecordBtn, mPauseBtn;
private TextView mTimeTextView, mRecordTextView;
private Thread timeThread = null;
private Boolean isRunning = false;
ArrayList<String> record = new ArrayList<>();
Boolean timeThreadd = false;

mRecordBtn = (Button) findViewById(R.id.btn_record);

mRecordTextView = (TextView) findViewById(R.id.recordView);
mStartBtn.setOnClickListener(new View.OnClickListener() {

mStopBtn.setVisibility(View.VISIBLE);
mRecordBtn.setVisibility(View.VISIBLE);
mPauseBtn.setVisibility(View.VISIBLE);

isRunning = true;
}// start 가 true 일때만 실행된다.

}
});

mRecordTextView.setText("");
mTimeTextView.setText("00:00:00:00");
timeThread.interrupt();
i = 0;
mEndTime = 0;
timeThreadd = false;
isRunning = false;
if (record.size() > 1) {
for (int i = 0; i < record.size(); i++) {
record.remove(i);
}
}
SharedPreferences sharedPreferences = getSharedPreferences("timer", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.clear();
editor.apply();
}
});
mRecordBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
record.add(mTimeTextView.getText().toString());
mRecordTextView.setText(mRecordTextView.getText() + mTimeTextView.getText().toString() + "\n");
}// 앞에 mRecordTextView.getText()은 n번이상 저장할때 첫번째 값을 n-1번째 라인에 놓고
}); // n번째 저장한것을 n번째 놓기 위해서 설정
mPauseBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
isRunning = !isRunning;
if (isRunning) {
mPauseBtn.setText("PAUSE");
} else {
mPauseBtn.setText("PAUSE");
}
}
});
}

int b = sharedpreferences.getInt("recordsize", 0);
for (int i = 0; i < b; i++) {
String c = sharedpreferences.getString("record" + i, null);
record.add(c);
mRecordTextView.setText(mRecordTextView.getText() + c + "\n");
}
if (isRunning) {
mEndTime = sharedpreferences.getLong("endTime", 0);
Log.v(" set mEndTime",String.valueOf(mEndTime));
i = System.currentTimeMillis() / 10 - mEndTime;
Log.v(" set i",String.valueOf(i));
if (i < 0) {
isRunning = false;
i = 0;
mEndTime = 0;
timeThreadd = false;
mRecordBtn.setVisibility(View.GONE);
mStartBtn.setVisibility(View.VISIBLE);
mPauseBtn.setVisibility(View.GONE);
mRecordTextView.setText("");
mTimeTextView.setText("00:00:00:00");
} else if (i > 0) {
mStartBtn.setVisibility(View.GONE);
mStopBtn.setVisibility(View.VISIBLE);
mRecordBtn.setVisibility(View.VISIBLE);
mPauseBtn.setVisibility(View.VISIBLE);
timeThread = new Thread(new timeThread());
timeThread.start();
}
}
}
}

I solve the problem.
public void run() {
if(timeThreadd!= true){
mEndTime = System.currentTimeMillis() / 10 + i;
timeThreadd = true;
}
The problem was System.currentTimeMillis().
The System.currentTimeMillis() needs to store just one time when user push the start button.

Stop Timer on return to previous Activity

I have created a timer that starts timing on a handleClick() and continues timing throughout the app. When I return to the firstActivity I would like the timer to stop in the onResume(). however whenever I return to the firstActivity I get the following error below. How do I solve this?

I am using andEngine for Developing game and I also use vuforia for AR (Augmented Reality).But if i combine both the codes then i getting error as surfaceview null.
**and if it's not supported then what is the use for augmented reality object tracking in andenginre **

Problem seems to be in onAttachedToWindow(). Change the function as below and give it a try.
public void onAttachedToWindow() {
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}

your targetSdk must be less than 14.
try setting it to 13
Check this Answer. And it works for me.
