[Q] How to use Timer to restart record video for every preset interval time?

Can someone tell me how can i use something like a timer to start a video recording interval process for a period of time (eg: 5mins) then restarts to record another set of 5min video until the user intervene to stop the process..

someone please help...

Thread
you are writing a service, right? typically this service should also implement a thread. inside this thread you could implement your timer feature.
-didi

But the thing is i don't know how to even implement or even write the timer codes into my serviceRecording.java file... Can you help me on this?

i recently did this with a widget. i used an AlarmManager to set repeating alarms that would broadcast an intent that could be caught by a broadcastReciever and then do something... im at work now but when i get home i can try to give you some sample code.

you sure this needs to be a service? a service is something that is doing work but not at the forefront of the ui. its unseen. do you want your recording to be done in the background? i only ask because i did some research on services and found that they cannot be a BroadCastReciever and thus cannot use the AlarmManager that i said would work.
as far as a timer i have not looked into that particular class...
sorry i was no help. but if you decide to use the AlarmManager i could help

Someone recently recommended using these code to implement the sort of interval recording i wanted with this code below but i don't seems to know how to implement these codes into my current code could someone lend me a hand how how can can i implement the appropriate codes into my code to make my code work? Or is there simpler way to achieve "dynamic" (with Preferences) interval recording?
Code:
final ServiceRecording recording = ....
final AtomicBoolean started = new AtomicBoolean(false);
ScheduledExecutorService executor = Executors.newScheduledExecutor(1);
executor.scheduleAtFixedRate(new Runnable() { public void run() { //only stop if we have started if(started.get()) { recording.stop(); } else { started.set(true); } recording.start(); }}, 5, 5, TimeUnit.MINUTES);

Any progress on this? I was thinking you coukd have a private inner class in your service class that handles the timing with an AlarmManager
Im on my phone right now but something along these lines...
Private Class MyTimer extends BroadcastReciever {
//Implement onRecieve
Public void onRecieve(Context c, Intent i) {
//if intent matches 5min alarm
//start recording
}
Then in your service you can make a recurring alarm using the AlarmManager class to signal your inner class to start or even stop the recording based on what intent you pass it
When i get home ill right a bit more code as an example
From something awesome

i wrote a bit of code. its incomplete. and you will have to maybe mess with making the AlarmServicer class either static, public, private or something to make it work. basicly your service creates a five minute alarm directed at the AlarmServicer that it catches in the onRecieve() method and then starts your recording again and then creates another alarm directed at itself. you can use some if/then logic to change wether or not the alarm will be created again based on if the user wants it to stop or not. and then to get it going again the service would invoke the setOneTimeAlarm method again.
Code:
public class ServiceRecording extends Service {
// NEW CONSTANT
public static final String FIVE_MIN_ALARM = "FIVE_MIN_ALARM";
public static final int FIVE_MINUTES = 300;
@Override
public void onCreate() {
super.onCreate();
recordingStatus = false;
ServiceCamera = CameraTest.MainCamera;
surfaceView = CameraTest.surfaceView;
surfaceHolder = CameraTest.surfaceHolder;
//set the first alarm
AlarmServicer.setOneTimeAlarm(AlarmServicer.class, this, ServiceRecording.FIVE_MINUTES , ServiceRecording.FIVE_MIN_ALARM);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) { }
public boolean startRecording() {}
public void stopRecording() {}
// NEW CODE
private static class AlarmServicer extends BroadcastReciever {
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if (intent.getAction().equals(ServiceRecording.FIVE_MIN_ALARM)) {
ServiceRecording.startRecording();
//set another five min alarm
setOneTimeAlarm(AlarmServicer.class, this, ServiceRecording.FIVE_MINUTES, ServiceRecording.FIVE_MIN_ALARM;
}
}
private static void setOneTimeAlarm(java.lang.Class<?> cls, Context context, int seconds, String action) {
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, cls);
intent.setAction(action);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (seconds * 1000), pendingIntent);
}
}
}
and i believe that you need to register the inner class as a broadcastreciever in the android manifest.

everything is fine.. there is no error in code. even the toast come up when i press the submit button..
but it is not sending message .. plzz help
Edit1 app is sending sms now but not on schedule time . it is sending sms instantly

I know this may be a silly question but did you add the proper permissions to your manifest for sending sms?

yes i already added the permission.. check the edit in the main post. it is sending sms but not at schedule time.

This is how I did mine:
MainActivity button click event (or some other event):
Code:
//Now let's set up the alarm
Intent intent = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(MeterMaid.this,
0, intent, 0);
// We want the alarm to go off 30 seconds from now. Calendar.MINUTE
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(SECONDS_OR_MINUTES, (picker.getValue() - REMINDER_OFFSET));
// Schedule the alarm!
am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender);
And my service to receive the alarm:
Code:
public class AlarmReceiver extends BroadcastReceiver
{
private int SIMPLE_NOTFICATION_ID;
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent)
{
NotificationManager manger = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.meter128, "expiration warning", System.currentTimeMillis());
//intent.putExtra("Ringtone", Uri.parse("file:///sdcard/test.mp3"));
intent.putExtra("vibrationPatern", new long[] { 200, 300 });
intent.putExtra("Testtone", RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM));
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0);
notification.setLatestEventInfo(context, "Time is up!", "Your time is about to expire!!", contentIntent);
notification.flags = Notification.FLAG_INSISTENT;
notification.sound = (Uri) intent.getParcelableExtra("Testtone"); //Uri.parse("file:///sdcard/test.mp3"); //
notification.vibrate = (long[]) intent.getExtras().get("vibrationPatern");
// The PendingIntent to launch our activity if the user selects this notification
manger.notify(SIMPLE_NOTFICATION_ID, notification);
}
}

Adding custom apps to an app switcher panel

Now I want to let the users define in the app settings up to 3 own apps that should be shown on every moment.
How should I do that?
Thank you

Loading a new fragment from an OnClick set in asyncTask

I have a fragment, which contains a button that when pressed loads a new fragment. The new fragment runs an async task to populate a listview with data.
I am running into trouble, trying to load a new fragment from the onClick. The problem is I can not get the getFragmentManager();
My async task looks like this:
Code:
public class GetStyleStatisticsJSON extends AsyncTask<String, Void, String> {
Context c;
private ProgressDialog Dialog;
android.support.v4.app.Fragment Fragment_one;

Dialog = new ProgressDialog(c);
}
@Override

// TODO Auto-generated method stub
return readJSONFeed(arg0[0]);
}
protected void onPreExecute() {
Dialog.setMessage("Analyzing Statistics");
Dialog.setTitle("Loading");
Dialog.setCancelable(false);
Dialog.show();
}
protected void onPostExecute(String result){

try{
JSONArray jsonArray = new JSONArray(result);
//acces listview

//make array list for beer
final List<StyleInfo> tasteList = new ArrayList<StyleInfo>();
for(int i = 0; i < jsonArray.length(); i++) {
String style = jsonArray.getJSONObject(i).getString("style");
String rate = jsonArray.getJSONObject(i).getString("rate");
String beerID = jsonArray.getJSONObject(i).getString("id");
int count = i + 1;
style = count + ". " + style;
//create object
StyleInfo tempTaste = new StyleInfo(style, rate, beerID);
//add to arraylist
tasteList.add(tempTaste);
//add items to listview
StyleInfoAdapter adapter1 = new StyleInfoAdapter(c ,R.layout.brewer_stats_listview, tasteList);
lv.setAdapter(adapter1);
//set up clicks

Hi,
To be able to call getFragmentManager() or getSupportFragmentManager() you'll need to use FragmentActivity, so what I would do is:
1. Make sure the activity that calls the asycTask is a FragmentActivity.
2. Pass this actvity to the asycTask.
Something like: (asyncTask method)
setActivity(Activity activity)
{
fm = activity.getFragmentManager();
}

thats the problem, I launch the asyncTask from a fragment....

Oh! So you'll access your activity like this:
getActivity().getFragmentManager();

FC when using interface to launch new fragment form listView

I have an async task that loads a list view of items. I am currently trying to set the onClick to load a new fragment with an "id" that is being retrieved from the list item that is clicked. I have no errors in my code that the Android Studio shows me.
When I run the app and click on the item in the list view I get this FC:

line 140 in ReadJSONResult is:
listenerBeer.onArticleSelected(idToSend);
That line is part of this whole onClick:
//set up clicks
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
BeerData beerInfo = beerList.get(arg2);
String idToSend = beerInfo.beerId;
//todo: launch beer fragment
listenerBeer.onArticleSelected(idToSend);
}
});

Let me know if you need any other code, I am stomped on this and could use a second pair of eyes. Thanks.
