[android-beginners] Questions for the group regarding URL Launchers
I have long had my WAP pages built and had my URL launchers built by an outsourced group in India. I now have a requirement to update my .apk files to 2.2 as well as build 6 additional .apk files that are made up of 6 completely different URL launchers to other WAP sites. I have successfully set up my Java and SDK environment My questions are: - What is the best recommendation the group can suggest as a starting point? - How do I open the .apk file in my eclipse environment to make the changes necessary? The Android Market says the following when I attempt to upload my .apk file: [quote] Market does not accept apks signed with the debug certificate. Create a new certificate that is valid for at least 50 years. Market requires that the certificate used to sign the apk be valid until at least October 22, 2033. Create a new certificate. Market requires the minSdkVersion to be set to a positive 32-bit integer in AndroidManifest.xml.

Re: [android-beginners] problem with httpclient and self signed certificates
Just an off the top of my head, but do you have a self-signed certificate?
BTW, I got your first email - double posting really isn't necessary

[android-beginners] problem with httpclient and self signed certificates
Hi,
I am sure this has been discussed in this group, but I couldn't find
that thread, so bear with it, or if possible merge it with the
original.
I am using httpclient for my android app and I have a local site which
has a few https pages. Since default httpclient doesnot allow self-
signed certificates I am using "EasySSLFactory" and
"EasyX509TrustManager", which are mentioned in httpclient
documentation.
client = new DefaultHttpClient();
client.getConnectionManager().getSchemeRegistry().register(new
Scheme("https", new EasySSLSocketFactory(), 443));
The problem is if I use this SSLFactory in my android app, I am
getting correct response from my site's https pages, but I get "SSL
handshake failure: I/O error during system call, Unknown error: 0" for
sites such as "gmail.com", "ymail.com". If I don't use
"EasySSLSocketFactory" I get response from these sites but get
exception for my site.
The funny thing is that this page fetch code works fine as a
standalone java application.
What could be the problem. Please help me with this.
Thanks and Regards

getting correct response from my site's https pages, but I get "SSL

Re: [android-beginners] Adding a button which opens another screen
When you click the button, launch a new activity with startActivity(). That
method takes an Intent through which you can pass data to the activity you
are calling.
When you do it this way, pressing the back button automatically has the
effect you want by virtue of how the Android OS works.

[android-beginners] Adding a button which opens another screen
I have written a app, and I have pictures which are stored in the /
drawable directory. My app makes a sliding gallery across the top,
(id gallery1) and as you select the picture in the gallery it load
the
picture bigger underneath, (id image1). These a layed out in a XML
file. There is a button below the image (image1) which is called (id
mybutton).
I want it when a image comes up, when the button is pressed it loads
the same image on a XML layout file, in which the picture is full
screen, the ID of the XML file image is (id bigpic), and then from
there to beable to press the back button to go back to the gallery
screen. Can anyone help?
My Whole Code is:
***
**
public class PicViews extends Activity

R.drawable.pic05
};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.displayview);
Gallery gallery = (Gallery) findViewById(R.id.gallery1);
gallery.setAdapter(new ImageAdapter(this));
gallery.setOnItemClickListener(new OnItemClickListener()

Re: [android-beginners] Re: Triggering an AppWidget Update
Jake, The 30 minute minimum intervals only applies to updates specified in the widget's XML file (updateTimeMillis). You can have alarm-driven (or other event driven) updates as often as you like, so it's only a question of judgement with respect to battery life. Android 2.x includes analog clocks that update once a minute, so it can't be that bad. Avoiding updates when the screen is off is pretty easy - just use alarm options without the _WAKEUP (i.e. ELAPSED_REALTIME or RTC). If such alarm goes of while the phone is asleep, it will be delivered when the phone wakes up. -- Kostya 24.06.2010 19:36, Jake Colman пишет: But in the second example, would it be appropriate to update every minute? But Android 2.2 only allows an update every 30 minutes. Do you set an alarm to trigger even minute or would that also drain the battery? Do you trigger an update only when the screen is turned on? Can that even be detected? -- Kostya Vasilev -- WiFi Manager + pretty widget -- http://kmansoft.wordpress.com -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.

Kostya, This is actually a theoretical discussion since I'm trying to understand how this type of problem, as opposed to this actual problem, can be solved. If the data to be updated is fixed, then it sounds like you would want an intent to be fired when the data changes. So in my first example, the problem can be solved by firing an intent when the appointment time has passed so that you get the time of the next appointment or forcing an update when the a new appointment is added. But in the second example, would it be appropriate to update every minute? But Android 2.2 only allows an update every 30 minutes. Do you set an alarm to trigger even minute or would that also drain the battery? Do you trigger an update only when the screen is turned on? Can that even be detected? -- Jake Colman -- Android Tinkerer -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

Re: [android-beginners] Re: Triggering an AppWidget Update

So I guess the best approach would be to set an alarm to trigger at the time of the next appointment so that I wake up and get the next time to display. That makes sense and limits the number of times that I wake up to do an update. But let's say the appwidget displays the amount of time remaining until the next appointment.

Re: [android-beginners] Triggering an AppWidget Update
Jake, There are two scenarios involved: 1. Android calls the widget provider's onUpdate() - when the widget is first shown and then regularly at updatePeriodMillis intervals, if specified. Note that automatic updates based on updatePeriodMillis are limited to once every 30 minutes since Android 2.x. 2. You are free to update your widgets any time, by doing something like this: ComponentName thisWidget = new ComponentName(context, MyWidgetProvider.class); AppWidgetManager manager = AppWidgetManager.getInstance(context); RemoteViews updateViews = .. specify new widget state here .. manager.updateAppWidget(thisWidget, updateViews); For your calendar example, obviously the second scenario has to be involved. As for performing updates when necessary (and only then), your code needs to contain some logic to figure out the appropriate time for the next update (based on actual calendar events and how much in advance they are supposed to be displayed). Then set an alarm using AlarmManager to update the widget. Note that AlarmManager does not have to be used in a service, although sample code typically does. An alarm simply fires off a PendingIntent. This intent can be specific to your code, triggering a widget update just in time to for next scheduled calendar event. A good place to receive this special intent is in your AppWidgetProvider - since it's a BroadcastReceiver anyway. Hope this helps. -- Kostya 24.06.2010 18:31, Jake Colman пишет: I have some questions about the correct approach for updating an AppWidget's display. Since this is a beginners forum, please let me state what I already do know: 1) I can use android::updatePeriodMillis to specify the update interval. When this interval has elapsed the phone is woken up. Intervals of less than one hour are not a good idea. 2) Updates can be triggered by an alarm that will not actually wake up the phone. What I'm confused about is how/why/when to trigger an update. Let's say I am creating an AppWidget that will display the time of my next appointment. The widget needs to know the current time and the time of my next appointment. When the current time is after the current appointment the widget has to display the time of the next appointment. For this widget to work it must be regularly checking the time and the calendar since at any minute it might be time to display the next appointment. Does this mean I have to update the widget's display every minute? Clearly not, but how else? In actuality, I only really need to update the display if the user is looking at the screen. But do we only update if the screen is active? If so, what about if that update is a time-consuming process? The UI would then appear non-responsive. So what the is correct approach for this kind of problem?

[android-beginners] Re: Approach to learning android
All you need is to concentrate on Java programming. There are lot of good book available in the market to learn Java. One of them is Ivor Horton's book on wrox (http://www.wrox.com). Another one is Java -How to program by Deitel & Deitel (http://www.deitel.com/). Also get hold of Mark Murphy's book: http://www.commonsware.com/ On Jun 21, 3:10 pm, Justin Anderson wrote: > That is because both Java and C++ are object oriented...

[android-beginners] Triggering an AppWidget Update
I have some questions about the correct approach for updating an AppWidget's display. Since this is a beginners forum, please let me state what I already do know: 1) I can use android::updatePeriodMillis to specify the update interval. When this interval has elapsed the phone is woken up. Intervals of less than one hour are not a good idea. 2) Updates can be triggered by an alarm that will not actually wake up the phone. What I'm confused about is how/why/when to trigger an update. Let's say I am creating an AppWidget that will display the time of my next appointment. The widget needs to know the current time and the time of my next appointment. When the current time is after the current appointment the widget has to display the time of the next appointment. For this widget to work it must be regularly checking the time and the calendar since at any minute it might be time to display the next appointment. Does this mean I have to update the widget's display every minute? Clearly not, but how else? In actuality, I only really need to update the display if the user is looking at the screen. But do we only update if the screen is active? If so, what about if that update is a time-consuming process? The UI would then appear non-responsive. So what the is correct approach for this kind of problem?

[android-beginners] Saving Pictures from /drawable in a app to SD Card
I kind of confussed and hope one of you nice people will help me.
I have written a app, and I have pictures which are stored in the /
drawable directory. My app makes a sliding gallery across the top,
(id gallery1) and as you select the picture in the gallery it load the
picture bigger underneath, (id image1). These a layed out in a XML
file. What I would like to do is be able to is when the image1 is
pressed it gives the option to save the picture on the SD Card.
My Whole Code is:
*
public class PicViews extends Activity
{
//---the images to display---
Integer[] imageIDs = {
R.drawable.pic01,
R.drawable.pic02,
R.drawable.pic03,
R.drawable.pic04,
R.drawable.pic05
};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.displayview);
Gallery gallery = (Gallery) findViewById(R.id.gallery1);
gallery.setAdapter(new ImageAdapter(this));
gallery.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView parent,
View v, int position, long id)
{
//---display the images selected---
ImageView imageView = (ImageView)
findViewById(R.id.image1);
imageView.setImageResource(imageIDs[position]);
}
});
}
public class ImageAdapter extends BaseAdapter
{
private Context context;
private int itemBackground;
public ImageAdapter(Context c)
{
context = c;
//---setting the style---
TypedArray a =
obtainStyledAttributes(R.styleable.Gallery1);
itemBackground = a.getResourceId(
R.styleable.Gallery1_android_galleryItemBackground,
0);
a.recycle();
}
//---returns the number of images---
public int getCount() {
return imageIDs.length;
}
//---returns the ID of an item---
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
//---returns an ImageView view---
public View getView(int position, View convertView, ViewGroup
parent) {
ImageView imageView = new ImageView(context);
imageView.setImageResource(imageIDs[position]);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setLayoutParams(new Gallery.LayoutParams(150,
120));
imageView.setBackgroundResource(itemBackground);
return imageView;
}
}
}
*
The Section of code which pulls up the image and makes the bigger
picture show is:
*
gallery.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView parent,
View v, int position, long id)
{
//---display the images selected---
ImageView imageView = (ImageView)
findViewById(R.id.image1);
imageView.setImageResource(imageIDs[position]);
}
});
**
Its at this point I want to be able to have a option to save the
picture either by pressing a button or ideally pressing the picture
which will bring up options.
Also what alterations in the manifest do I need to make to be able to
access the SD Card Storage?
Please help, I'm only learning.

Re: [android-beginners] Re: onHandleIntent(Intent) method does not get called
24.06.2010 10:49, appsgrrl пишет: Hi -- Okay, I got further! Yay! It turns out that I also had to call super.onCreate() to avoid the null pointer exception. So, if I call super.onCreate() and super.onStartCommand(), my onHandleIntent() does get excecuted. Great. Both superclass methods need to get called - onCreate() set up a worker thread, and onStartCommand() queues the intent to this thread, which ultimately calls your onHandleIntent() Now, my new mystery is why my service gets an onDestroy() call right after it is started. I return START_STICKY from onStartCommand, but that does not seem to have an effect. I guess I need to understand the life cycle stuff a little more. This is intended behaviour. The service is stopped when the last queued intent has been processed by your subclass's onHandleIntent(). -- Kostya Vasilev -- WiFi Manager + pretty widget -- http://kmansoft.wordpress.com -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.
