[Q] How to create youtube start/stop function for video recording function? HELP!

Is there a way to get the entire surfaceView screen to function like a button which start/atop a video recording process whenever it sees fit by the user? The function is somewhat similar to youTube's start/stop play function but instead this time it is used to start/stop the video recording process.
Is the code suppose to be coded in the .xml file or my .java file to accomplish the task? Sorry i'm rather new to android/java and given only 6 more weeks to finish this assignment by my lecturer to complete an app which act like a car blackbox yet i'm a total beginner in programming... Any help would be appreciated... Thanks in advance...
This is what i tried so far, can someone guide me i'm really in a desperate situation, PLEASE HELP ME :'(

public class CameraTest extends Activity implements SurfaceHolder.Callback {

someone answer me please, i really need your guys help...

why isn't someone answering is my question so unwelcoming?

Haiz can anyone help me, i really need some guidance and help here...

You want to
Code:
implement OnClickListener
add method
Code:
onClick(View v)
then you want to add
Code:
surfaceView.setOnClickListener(this);
When surface is clicked onClick is called

By any chance could you explain how should i implement the above said functions into my codes because like implement onclicklistener and this and that i don't quite understand where should i place these above codes??
And how should this above function handle my startService and stopService intents? Will the surfaceview also the show the same invisible button effects seen in youtube too when being clicked? Could you guide me in this in much more details, sorry if i'm kinna stupid to understand your explanations...

Ok
CameraTest.java
Add
Code:
public void onClick(View v){
}
Replace
Code:
public class CameraTest extends Activity implements SurfaceHolder.Callback {
with
Code:
public class CameraTest extends Activity implements SurfaceHolder.Callback, OnClickListener {
After
Code:
surfaceView = (SurfaceView)findViewById(R.id.surface_camera);
Add
Code:
surfaceView.setOnClickListener(this);
how should this above function handle my startService and stopService intents?
Click to expand...
Click to collapse
Your intent function calls the CameraTest.surfaceView so everything will work with whatever code you put in the onClick function.
Will the surfaceview also the show the same invisible button effects seen in youtube too when being clicked?
Click to expand...
Click to collapse
Need better explanation on what you are asking.

The last part is probably like how when you tap a YouTube video on the video itself it kinda flashes the play or pause button over the video.
Sent from my MIUI SCH-i500

Which of these should i import?
Code:
import android.content.DialogInterface.OnClickListener;
import android.view.View.OnClickListener;
Should i put startService and stopService intent together, but it seems not appropriate as both statement seems to conflict each other when i click to start/stop my service? Or i need add some sort of if.. else logic statement to differentiate the start/stop service alternating when being clicked?
Code:
public void onClick(View v){
startService(new Intent(getApplicationContext(), ServiceRecording.class));
startService(new Intent(getApplicationContext(), ServiceRecording.class));
}
Yes that was what i meant for the last part of my question the sort of effect it will display when being clicked, sorry if i could not explain well which might cause you some confusion.. Thanks for your help

Or should i be implementing some sort of imagebutton to emulate the above effect i mention or is there some other way to do it?

Can someone answer me??

Can someone please guide me on my above problem to get the result similar to what was like youtube??

[Q] What are the types of video encoding/resolution available for android?

Could someone name me the various types of video encoding/resolution type available for encoding/resolution video recording purposes in android? Like mp4, etc...
Now that i think of it is it possible for me to retrieve my phone's camera resolution for user to use for preferences purposes? Does it have to do with flatten something thingy, i'm not quite sure what its called..
If so how should i retrieve a particular phone's resolution for ListPreference?? Can someone guide me on this?

Could someone guide me along this??

I'm not really sure what you're asking, nor what the code you've displayed has to do with it.
Have you checked out the CamcorderProfile class?
http://developer.android.com/reference/android/media/CamcorderProfile.html

Q1. What are the available different forms of video encoding type available in android for user to choose from? Because i'm currently doing a video recording app which i wanted to use ListPreference to allow user to dynamically choose what type of encoding is available.
Q2. I wanted to know is there any easy way to retrieve video resolution on the actual phone? Because different phone has different phone resolution's compatibility, so i wanted to retrieve the resolution data and display the different resolutions dynamically into my ListPreference for user selection... Does it have to do with a method name "flatten()" i don't quite know what is the method... I'm kinna new in java/android, can someone guide me on how should i do that?

Can someone guide on how am i going to obtain my dynamic video resolution for every single phone instead of using the hard-coding xml method into my ListPreferenes??

[Q] How should i extract the appropriate video resolution and use in ListPreference?

I wanted to know is there any easy way to retrieve video resolution on the actual phone? Because different phone has different phone resolution's compatibility, so i wanted to retrieve the phone's resolution string data and display the different resolutions dynamically into my ListPreference for user selection...
Does it have to do with extracting the string from log.d, substituting the appropriate resolution values and populate into my ListPreference, does it have to do with some Split method? If so how should i do it i'm a newbie in java/android can someone guide me on how should i do that?

I really need some guide from you guys please??

I know it has to do with split something but i'm kinna stuck here can someone guide me on this?? Even after i get the appropriate height and width how should i use the values to be used in ListPreferences?

Widget for turning on/off camera flashlight (Android , Eclipse)

I've seen Widget for turning on/off camera flashlight in android but for some unknown reasons its not working I would really appreciate it if someone could help me. I've been trying for over 2 days.There isn't any error in eclipse.
QFlashlightWidgetProvider class:
Code:
public class QFlashlightWidgetProvider extends AppWidgetProvider {
[user=439709]@override[/user]
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
Intent receiver = new Intent(context, QFlashlightWidgetProvider.class);
receiver.setAction("COM_FLASHLIGHT");
receiver.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, receiver, 0);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.qflashlight_appwidget);
views.setOnClickPendingIntent(R.id.flashtoggle, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, views);
}
}
class QFlashlightWidgetReceiver
Code:
class QFlashlightWidgetReceiver extends BroadcastReceiver {
private static boolean isLightOn = false;
private static Camera camera;
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent) {
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.qflashlight_appwidget);
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
appWidgetManager.updateAppWidget(new ComponentName(context, QFlashlightWidgetProvider.class),
views);
Toast.makeText(context, "Turning Cam On", Toast.LENGTH_SHORT).show();
}
}
Manifest.xml
Code:
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />
Code:
<meta-data android:name="android.appwidget.provider"
android:resource="@xml/qflashlight_appwidget_info" />
</receiver>
<receiver android:name="QFlashLightWidgetReceiver">
<intent-filter>
<action android:name="COM_FLASHLIGHT"></action>
</intent-filter>
</receiver>
P.S: I removed the code for turning the cam on/off and put a toast message but even the toast message isn't showing.The widget should display a toast message when clicked(I will put the code to turn on the flash when i succeed in making it display a toast)

Example of an app that runs as a service(and does some work periodically in a thread)

Hi there,
Can you share please a link to simple example of an app that runs as a service(and does some work periodically in a thread) and started at boot? It should not be an activity. Thank you.

Not a link, but should be good to start:
AndroidManifest.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest package="your.package" android:versionCode="1" android:versionName="1.0" >
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@android:style/Theme.NoDisplay">>
<receiver android:name=".Receiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:enabled="true" android:name=".YourService" />
</application>
</manifest>
Here you receive broadcast (Intent) dispatched by the system on boot.
Receiver.java
Code:
public class Receiver extends BroadcastReceiver {
@Override public void onReceive(Context context, Intent intent) {
Intent i = new Intent(this, YourService.class);
startService(i);
}
}
Service should do your work.
YourService.java
Code:
public class YourService extends Service {
@Override public void onStart(Intent intent, int startId) {
// do some work here
}

This is a simple implementation. To make it run periodically, try to use AlarmManager with IntentService.

I wrote an app that unfortunately doesn't start at boot. I am also aware (theoretically) of the change in policy of BroadcastReceiver from 3.1 version. But I could not catch what the point is, how I register the service from user activity?
public class AlarmScheduleActivity extends Activity {
// UI parameters
Button btnStart;
Button btnStop;
@override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnStart = (Button)findViewById(R.id.button1);
btnStop = (Button)findViewById(R.id.button2);
}
public void btnStartSchedule(View v) {
try {
AlarmManager alarms = (AlarmManager) this
.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getApplicationContext(),
AlarmReceiver.class);
intent.putExtra(AlarmReceiver.ACTION_ALARM,
AlarmReceiver.ACTION_ALARM);
final PendingIntent pIntent = PendingIntent.getBroadcast(this,
1234567, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarms.setRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis(), 2000, pIntent);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void btnCancelSchedules(View v) {
Intent intent = new Intent(getApplicationContext(),
AlarmReceiver.class);
intent.putExtra(AlarmReceiver.ACTION_ALARM,
AlarmReceiver.ACTION_ALARM);
final PendingIntent pIntent = PendingIntent.getBroadcast(this, 1234567,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarms = (AlarmManager) this
.getSystemService(Context.ALARM_SERVICE);
alarms.cancel(pIntent);
}
}
public class AlarmReceiver extends BroadcastReceiver {
public static String ACTION_ALARM = "com.alarammanager.alaram";
@override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
String action = bundle.getString(ACTION_ALARM);
if (action.equals(ACTION_ALARM)) {
Log.i("Alarm Receiver", "If loop");
Intent inService = new Intent(context,TaskService.class);
context.startService(inService);
}
}
}
public class BootBroadcastReceiver extends BroadcastReceiver {
 @override
public void onReceive(Context context, Intent intent) {
Intent alarmIntent = new Intent("com.company.android.AlarmReceiver");
PendingIntent pi = PendingIntent.getBroadcast(context, 0, alarmIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, System.currentTimeMillis(),
2000, pi);
}
}
public class TaskService extends IntentService {
public TaskService() {
super("TaskService");
// TODO Auto-generated constructor stub
}
 @override
protected void onHandleIntent(Intent arg0) {
// Do some task
Log.i("TaskService", "Service running: yes-yes-yes");
}
}
AndroidManifest.xml
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".AlarmScheduleActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".BootBroadcastReceiver"
android:enabled="true" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
<receiver
android:name="AlarmReceiver"
androidrocess=":remote" >
</receiver>
<service android:name=".TaskService" >
</service>
</application>

Any idea?
