Verify if there is video signal in videoview

I have a project in which it plays IPTV. I would like to identify if there is video signal in order to show an alertdialog if there isn't signal. I could set a timer to wait for the signal to return, but I don't know how to identify if there is a signal or not. Could you please help me. I leave the code with which I am working. SdkVersion 22.

I recommend you to change your approach! Use Exomedia or Exoplayer library. They are very simple.
Depend on your choice, you can use their function to solve your problem :)

Countdown Timer sometime, counts 2 seconds before the actual time

I have tried to make an countdown timer in a list veiw implementation. Each list item has a separate countdown timer that can be started or stopped. However I have noticed that if I add the first timer in list and set its time. When I start the timer it starts two seconds less than the actual time. e.g If I added a count down of 12 seconds. Then it will start counting from 10. But when the countdown is taking place and I add another new timer and set its time, it starts on the exact given time. The new counter starts at the wrong time only when either there is no other counter in the list or when all counters are already stopped and not counting down. Similarly it will only start the right time only when other timers are counting down. Would really appreciate if someone can help me figure out where is the problem. I have been looking at the code for days.

}
public void setCounterID(int id) {

}

return this.id;
}
}
And I add the time from number pickers of Hour, Minute and Second.
case R.id.counterStartStopButton:
long hour = TimeUnit.HOURS.toMillis(numberPickerHour.getValue());
long minute = TimeUnit.MINUTES.toMillis(numberPickerMinute.getValue());
long second = TimeUnit.SECONDS.toMillis(numberPickerSecond.getValue());
// if(getListSharedPreferences()) {
if(getCounterIDSharedPreferences()) {
counterID = counterID + 1;
list.add(new CounterData(hour + minute + second, counterID));
saveCounterIDSharedPreferences(counterID);
}
else {
counterID = 1;
list.add(new CounterData(hour + minute + second, counterID));
saveCounterIDSharedPreferences(counterID);
}
UPDATE
Here's the shared preferences code
public void saveCounterIDSharedPreferences(int id) {
SharedPreferences sharedPreferences = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
sharedPreferences.edit().putInt("Counter ID123", id).commit();
}
public boolean getCounterIDSharedPreferences() {
SharedPreferences sharedPreferences = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
if (sharedPreferences.getInt("Counter ID123", -1) != -1) {
counterID = sharedPreferences.getInt("Counter ID123", -1);
return true;
}
else
return false;
}

What turned out to work for me was changing the timer task as following:
private void startUpdateTimer() {
Timer tmr = new Timer();
tmr.schedule(new TimerTask() {
#Override
public void run() {
mHandler.post(updateRemainingTimeRunnable);
}
}, 500, 500);
}

Android playing video fullscreen in a new activity on button click

I'm streaming a video in my app, and it works fine.
The problem is that when I try to make it full screen (in a new activity or otherwise), the screen is blank.
I have tried doing it without starting a new activity, as suggested here:
In my main activity:
butFullScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if(isFS)
setContentView(R.layout.activity_full_screen_video);
else
setContentView(R.layout.activity_starting_point);
}
});
I've also tried opening it in a new activity (which I prefer):
butFullScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Start fs intent
Intent myIntent = new Intent(StartingPoint.this, FullScreenVideo.class);
StartingPoint.this.startActivity(myIntent);
}
});
Where FullScreenVideo:
public class FullScreenVideo extends StartingPoint{
//private VideoView vv;
public FullScreenVideo(){
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().hide();
setContentView(R.layout.activity_full_screen_video);
vv.start();
}
}
And activity_full_screen_video:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:background="#ff000000">
<VideoView
android:id="#+id/vv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
And in my manifest:
<activity
android:name=".FullScreenVideo"
android:label="#string/app_name"
android:screenOrientation="landscape"
android:configChanges="keyboardHidden|orientation|screenSize" />
It doesn't show any error or crash, just a blank screen. Also, I'm not using the media controller, so answers without that would be appreciated :)

My activity won't pause when dialog is shown

I have been working on application that displays a problem and 4 possible answers. Answer correctly, and the next problem appears. A wrong answer or letting the timer run out results in a popup that tells the correct answer and that you just lost a "life". Everything works well except that when the popup appears, the countdown timer continues and generates another popup. I can't find a way to get the activity to wait for the button on the dialog to be pressed before continuing to the next problem. I have read many questions/answers here and combed through many pages on the android developers site. Any help with this problem would be greatly appreciated.

You have a repetitive loop insisde a timer...
Let say, when your timer is is finished, it will call onFinish() and you are calling doWrong() in onFinish(). and doWrong() is calling doPopUp() which will open a Dialog again.(repetitively). To avoid, maintain some flags(like boolean or int) and based on the value of the flag, you decide whether to show PopUp Dialog when timer is finished or cancel the Timer when you are dismissing Diaog...

Log.v("Events", "DoWrong");
counter.cancel();
soundwrong.start();

} else {

}

l3 = getResources().getString(R.string.CorrAnswer)+" "+corrAnswer;
}
// change here

I'm adding this answer to be able to mark the question as answered. Please read the comment I left after the question.
Thanks to all that provide help on this site. I have gained much knowledge here.

unable to rate my app

I am using the below class to rate my app. But the every time I do this, it says "Requested item not found". but the link < play.google.com/store/apps/details?id=com.xxx.xxx > works perfectly in the browser. Why is it not working here?
One more thing I noticed that if I change the package name to the same of some other app, it works. Is there any chance that something might have been missed while uploading the previous version?
public class apprater {
private final static String APP_TITLE = "abcd";
private final static String APP_PNAME = "com.xxx.xxx";
private final static int DAYS_UNTIL_PROMPT = 3;
private final static int LAUNCHES_UNTIL_PROMPT = 7;
public static void app_launched(Context mContext) {
SharedPreferences prefs = mContext.getSharedPreferences("apprater", 0);
if (prefs.getBoolean("dontshowagain", false)) { return ; }
SharedPreferences.Editor editor = prefs.edit();
// Increment launch counter
long launch_count = prefs.getLong("launch_count", 0) + 1;
editor.putLong("launch_count", launch_count);
// Get date of first launch
Long date_firstLaunch = prefs.getLong("date_firstlaunch", 0);
if (date_firstLaunch == 0) {
date_firstLaunch = System.currentTimeMillis();
editor.putLong("date_firstlaunch", date_firstLaunch);
}
// Wait at least n days before opening
if (launch_count >= LAUNCHES_UNTIL_PROMPT) {
if (System.currentTimeMillis() >= date_firstLaunch +
(DAYS_UNTIL_PROMPT * 24 * 60 * 60 * 1000)) {
showRateDialog(mContext, editor);
}
}
editor.commit();
}
public static void showRateDialog(final Context mContext, final SharedPreferences.Editor editor) {
final Dialog dialog = new Dialog(mContext);
dialog.setTitle("Rate " + APP_TITLE);
LinearLayout ll = new LinearLayout(mContext);
ll.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(mContext);
tv.setText("If you enjoy using " + APP_TITLE + ", please take a moment to rate it. Thanks for your support!");
tv.setWidth(240);
tv.setPadding(4, 0, 4, 10);
ll.addView(tv);
Button b1 = new Button(mContext);
b1.setText("Rate " + APP_TITLE);
b1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mContext.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + APP_PNAME)));
System.out.println("eeeeeeeeeeeee: "+APP_PNAME);
dialog.dismiss();
}
});
ll.addView(b1);
Button b2 = new Button(mContext);
b2.setText("Remind me later");
b2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
dialog.dismiss();
}
});
ll.addView(b2);
Button b3 = new Button(mContext);
b3.setText("No, thanks");
b3.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (editor != null) {
editor.putBoolean("dontshowagain", true);
editor.commit();
}
dialog.dismiss();
}
});
ll.addView(b3);
dialog.setContentView(ll);
dialog.show();
}
}
This what I am using now:
public void onClick(View v) {
final String appName = APP_PNAME;
try
{
mContext.startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=com.xxx.xxx")));
}
catch (android.content.ActivityNotFoundException anfe)
{
mContext.startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://play.google.com/store/apps/details?id=com.xxx.xxx")));
}
// mContext.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + APP_PNAME)));
dialog.dismiss();
}

Try this one
final String appName = getPackageName();
try
{
startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id="+ appName)));
}
catch (android.content.ActivityNotFoundException anfe)
{
startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://play.google.com/store/apps/details?id="+ appName)));
}
