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;
long i;
long mEndTime;

}
mStartBtn = (Button) findViewById(R.id.btn_start);
mStopBtn = (Button) findViewById(R.id.btn_stop);
mRecordBtn = (Button) findViewById(R.id.btn_record);
mPauseBtn = (Button) findViewById(R.id.btn_pause);
mTimeTextView = (TextView) findViewById(R.id.timeView);
mRecordTextView = (TextView) findViewById(R.id.recordView);
mStartBtn.setOnClickListener(new View.OnClickListener() {
#Override

mStopBtn.setVisibility(View.VISIBLE);
mRecordBtn.setVisibility(View.VISIBLE);
mPauseBtn.setVisibility(View.VISIBLE);
if (isRunning != true) {

}// start 가 true 일때만 실행된다.

timeThread.start();
}
});

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.

I am trying to run chronometer inside a Service. But I am not able to run it. I press a button in Activity and that event is passed to the Service. If the button in pressed then start the Chronometer but problem is setOnChronometerTickListener is called only once and it stops. Where am I making mistake? Here is my Service and Activity class:

The Chronometer is a View, that is, a UI element. You never add your Chronometer to any layout, I guess that's why it's never updating.
You could try using a CountDownTimer or a Handler / Runnable combination.
http://developer.android.com/reference/android/os/CountDownTimer.html http://developer.android.com/reference/android/os/Handler.html
Here's an example using Handler / Runnable, I've even thrown in a stopTimer() method for good measure:
private Handler timerHandler;
private Runnable timerRunnable;
// ...
#Override
public void onCreate() {
super.onCreate();
Log.d(LOG_TAG, "TimerService created");
timerHandler = new Handler();
timerRunnable = new Runnable() {
#Override
public void run() {
Log.d(LOG_TAG, "TICK");
timerHandler.postDelayed(timerRunnable, 1000);
}
};
}
public void startTimer() {
Log.d(LOG_TAG, "Timer started");
timerHandler.post(timerRunnable);
}
public void stopTimer() {
Log.d(LOG_TAG, "Timer stopped");
timerHandler.removeCallbacks(timerRunnable);
}
Here is a video which do not use Handler and directly implement the chronometer ,
Do check it out...
https://youtu.be/RLnb4vVkftc
Plus I had this problem I solved by removing
android:format="00:00"
from Chronometer in activity_main.xml
So my code looks like this :
<Chronometer
android:id="#+id/chronometer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:height="20sp"
android:foregroundGravity="fill_horizontal|top|bottom|center|fill_vertical|fill"
android:maxLines="2"
android:minLines="2"
android:textColor="#FFF"
android:textSize="40sp"
android:verticalScrollbarPosition="defaultPosition"
app:layout_constraintBottom_toBottomOf="#+id/progress_breathing"
app:layout_constraintEnd_toEndOf="#+id/progress_breathing"
app:layout_constraintStart_toStartOf="#+id/progress_breathing"
app:layout_constraintTop_toTopOf="#+id/progress_breathing"
app:layout_constraintVertical_bias="0.43" />

Player is working fine. But when the device locks and activity resumes the player is not resuming the playback.Please help me to resolve this issue.
Thanks in advance.
Try changing on resume with the below code
#Override
protected void onResume() {
//satatus bar color setting
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.setStatusBarColor(Color.TRANSPARENT);
}
if (isresume) {
isresume=false;
player.stop();
player.clearVideoSurface();
isInPlayer = false;
seekto = Constants.playerPosition;
initPlayer();
loadPlayer();
} else {
loadPlayer();
}
super.onResume();
}
I am creating a countdown time in Android and I have the timer part working perfectly. However, I want to add a feature where the user can set the number of times they wish the timer to repeat. This is my current attempt at implementation
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.textView);
minutesText = (EditText) findViewById(R.id.minutesText);
secondsText = (EditText) findViewById(R.id.secondsText);
startButton = (Button) findViewById(R.id.startButton);
intervalCount = (EditText) findViewById(R.id.intervalCount);
startButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (minutesText.getText().toString().equals("")) {
minutesInt = 0;
} else {
minutesString = minutesText.getText().toString();
minutesInt = Integer.parseInt(minutesString);
}
secondsString = secondsText.getText().toString();
if (secondsText.getText().toString().equals("")) {
secondsInt = 0;
} else {
secondsString = secondsText.getText().toString();
secondsInt = Integer.parseInt(secondsString);
}
intervalsString = intervalCount.getText().toString();
intervals = Integer.parseInt(intervalsString);
final int timerAmount = ((minutesInt * 60) + (secondsInt)) * 1000;
CountDownTimer timer = new CountDownTimer(timerAmount, 1000) {
#RequiresApi(api = Build.VERSION_CODES.N)
public void onTick(long millisUntilFinished) {
isRunning = true;
String timeLeft = String.format("%02d : %02d",
TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished),
TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished))
);
textView.setText("Reamining: " + timeLeft);
}
public void onFinish() {
isRunning = false;
intervals--;
if (intervals > 0) {
timer.start();
}
try {
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
r.play();
} catch (Exception e) {
e.printStackTrace();
}
}
};timer.start();
}
});
My error is in the onFinish()
it wont let me use timer.start()
CountDownTimer basically uses a Handler thread which is like other threads can not be restarted once its ended.
You need to use a new instance of the CountDownTimer in each interval.
So in your case, bring the
intervals--;
if (intervals > 0) {
// for each interval left create a new CountDownTimer here and start it.
}
outside of
new CountDownTimer(timerAmount, 1000 } {
// do your operations here.
}
There is a memory leak reported by LeakCanary in my Android App. I have Googled and studied for days and cannot find any solution. The leaked object is an instance of Activity called "MakeFire".

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.
