[android-developers] Polling at regular intervals in Android

[Archana]

Hi, I have 2 nanoHTTPD servers running in 2 instances of the emulator. The 
clients in both emulators should periodically poll to find if file got 
updated in server(every 5 minutes may be). Please let me know how  to 
implement this(as I am relatively new to Android)? Should i use Alarm 
Manager or create a Service?

Any help is appreciated.. Thank you!

[android-developers] Listview - Header , footer issue

[Jovish P]

In one of screen  we want to come up with a desing like this

Textview
Listview
Textview
Listview

First we thought of putting everything inside a linear layout with vertical
orientation and put that layout inside
a scroll view. Then we come to know that it is not a good idea. So right
now what we are trying to do is
add header and footer for listview. Header view will be a text view and
footer view will be a layout which conatins
a texview and listview. The problem what we are facing now is ,  we are not
able to scroll the second listview which is in
footerview layout. Is it a good solution ? If not wht is the best way to do
this ? Share your thoughts about this.

[android-developers] Re: Wrong apk starts-up

[katarina]

Hi All,

thanks very much for your answers, we didn't know about domains, will
have to change that.

Actually the apk file has a different name, but within the Manifest we
have application and activity names the same as the original mms
application - do you think this can produce the cofusion too?

Can it be because of the applicaiton name inside the Manifes or
activity name inside the Manifest - do they have to be unique across
all Manifest files?

Thanks again very much for your answers, we are novices with Android
and ignorant of many things.

Regards,
Katarina

Ok. 1 more clarification. Will the task execute even if I exit the

Hi Everyone,

Re: [android-developers] New to Android App Development need Advice in Designing UI

[Anees Thyrantakath]

I created 10 textview, 10 edittext, 3 buttons and a List View in and XML
file. and in Java class i extends from Activity. Then Listview is not
Working and when i extends ListActivity while running on Emulator it showed
Force To Close Error.
I'm Trying to Get a Better Option. If i can't do by adding all in a single
screen i think i have to create a next button so that remaining
informations we can edit from new Page.

Thanks

[android-developers] Re: Polling at regular intervals in Android

[Archana]

Should I have the alarm manager as a service?(as I want the application to 
be executed always)...  

Here is my service:

public class PollService extends Service
{
private PendingIntent pendingIntent;
private AlarmManager alarmManager;
private Calendar calendar; 
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public boolean onUnbind(Intent intent) {
return super.onUnbind(intent);
}

@Override
public void onCreate() {
Toast.makeText(getApplicationContext(), "Service Started",
Toast.LENGTH_SHORT).show();
alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent myIntent = new Intent(this, PollService.class);
pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
calendar = Calendar.getInstance();
}
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.MILLISECOND, 30);// Polling for every 5 minutes
alarmManager.set(AlarmManager.RTC_WAKEUP, 
calendar.getTimeInMillis(),pendingIntent);
}
 @Override
public void onDestroy() {
super.onDestroy();
alarmManager.cancel(pendingIntent);
} 
}

But where do I define connecting to the server and getting the contents?

Thank you.

[android-developers] Re: Listview - Header , footer issue

[Piren]

Android doesn't support putting two scrollable views one inside the other 
and i assume you dont want to divide the screen area between the listviews 
and make each take a constant size.

You're best (and probably only) choice is to just do everything manually. 
put a linear layout inside a scrollview and inflate everything in it 
manually. (the two textviews and the two listviews).
you can actually use the same code you wrote for your listviews to do that 
with some modifications.
It sounds like a lot of effort, but after doing it a few times i've noticed 
that it isnt. in some instances it even makes stuff easier.

Use AsyncTask or background thread or a thread in a Service.  To get a 
better answer you will need to ask a better question.

[android-developers] Layout is corrupted with graphics from another layout? Only at runtime, only on a certain device.

[NickL]

I have never seen this before, and have been developing apps for 2 years+.  
I wrote a layout, ran it on an old handset (HTC Android 2.2), and one of 
the dialogs (android.Theme.Dialog) has graphics in it from a different 
layout.  The other layout is not a dialog.  Not that that probably matters. 
 
In eclipse, this does not happen. On a tablet (4.0.3) and a Motorola (2.3) 
this never occurs (yet).  I thought this might have happened because I 
uploaded a debug version over a bad cable, and maybe got a bad copy.  But 
then I de-installed it and loaded it from the Google Play market, and it 
occurs only some of the time.  I have even tried modifying that layout and 
re-installing.  Still occurs infrequently.  Could it be a memory problem?  
 
Has anyone seen this occur?  How to prevent it?

[android-developers] How to deliver a free app, but purchase expansions?

[Andrew Cesario]

I am designing my first game for android and I would like to give away the 
base game which would be downloaded for free. This is a single player rpg, 
designed for use without internet access.  If people like it they can then 
buy other maps...like dungeons... or different weapons, scrolls etc.. 
 Different users could purchase the add-on items that they want, based on 
their choices in the game.  These would cost real money to buy.

How can I do this? 

My thoughts are as follows:
1) UNLOCK approach.
Initial download includes the entire software package. Users buy 'licences' 
directly (like an in app purchase).  When they enter their lic. code, it 
unlocks the items.  This seems to have a greater potential for hacking.

2) MULTIPLE APP approach.
Multiple apps for sale via google play. Use the free app to launch the 
purchased app if it exists on the device.

Any other ides or advice would be appreciated.  Any examples out there??

Look at how they manage in-app purchases.

[android-developers] Re: It is possible to stop a thread that is connecting to URL with httpConnection.connect()?

[Streets Of Boston]

Run the code you posted above in a back-ground thread (either as a plain 
thread or an AsyncTask's 'doInBackground(...)' implementation).

After 5 seconds or on user input, call either the back-ground thread's 
'interrupt()' method (if you are using a plain Thread) or 'cancel(true)' on 
your AsyncTask (if you're using AsyncTask).

Re: [android-developers] Buttons in ViewPager pages: Problem swiping/dragging pages when finger starts on top of Button. How can I fix this?

[Streets Of Boston]

Hi Kostya,

Thanks for your answer.

This bug (?) only happens on Jelly Bean (I don't have ICS devices to test 
it on).
It works fine on Honeycomb and lower OS versions. 

It seems there is indeed a regression of the ViewPager in JB (and possibly 
ICS).

Thanks.

I believe the APK file name doesn't really matter much.  It's what you
put into your manifest - specifically, the  element has a
"package" attribute whose value is your package name.  This package
name has to be unique - I don't think Android package manager would
let you install two different APKs on the same device whose manifests
both declared the same package name.

I guess it would be useful if you post more details about what exactly
you do - at least the manifests and how you install your APKs on your
device.

In-app billing seems to be an appropriate approach!

Re: [android-developers] Buttons in ViewPager pages: Problem swiping/dragging pages when finger starts on top of Button. How can I fix this?

[Piren]

ViewPager is part of the support package and inherits from a ViewGroup , it 
shouldn't matter much which OS version it runs on.
I have a similar setup and i dont experience this issue (using support 
package v4, i assume you're using the same since you said you tested on 
earlier os versions).
I can even press a button and see it switch to its pressed state and then 
start a swipe without generating an onClick event.

What is your targetSdkVersion?

[android-developers] Re: Layout is corrupted with graphics from another layout? Only at runtime, only on a certain device.

[Piren]

I've had it happen to me a lot of times, but as a packaging error 
(resources got packages incorrectly into the apk). but the issues were very 
broad and obvious and manifested on all of my devices.

Try a clean build of the app and see if it re-appears.

[android-developers] ClassCastException of LayoutParams to MarginLayoutParams after setting a view's width

[Timothy Caraballo]

I've posted this question to 
StackOverflow,
 
but no answer there yet, so I thought I'd ask here as well.

I've written a small proxy class so that I can use ObjectAnimator to 
animate a view's margin. After checking that this worked and everything 
animated properly, I wanted to adjust the view's size before the animation, 
but after I set the width, my animation fails with a ClassCastException. I 
haven't a clue why.

private class handleClickListener implements View.OnClickListener { private 
static final int LEFT_MARGIN_VISIBLE = 0; private static final int 
LEFT_MARGIN_HIDDEN = -196; public void onClick(View view) { LinearLayout 
row = (LinearLayout) view.getParent().getParent(); RelativeLayout options = 
(RelativeLayout) row.findViewById(R.id.options); LayoutProxy layoutProxy = 
new LayoutProxy(options); // First make sure the options are the right 
width to fill the screen with the handle int rowWidth = row.getWidth(); int 
handleWidth = view.getWidth(); layoutProxy.setWidth(rowWidth - 
handleWidth);ObjectAnimator animation
; if (layoutProxy.getLeftMargin() == Util.dipsToPixels(options, 
LEFT_MARGIN_VISIBLE)) { animation = ObjectAnimator.ofInt(layoutProxy, 
"leftMargin", Util.dipsToPixels(view, LEFT_MARGIN_VISIBLE), Util
.dipsToPixels(view, LEFT_MARGIN_HIDDEN)); } else { animation = 
ObjectAnimator.ofInt(layoutProxy, "leftMargin", Util.dipsToPixels(view, 
LEFT_MARGIN_HIDDEN), Util.dipsToPixels(view, LEFT_MARGIN_VISIBLE)); } 
animation.setDuration(200); animation.start(); } /** * Allows an 
ObjectAnimator to set/get margins and dimensions of a view */ private class 
LayoutProxy { private ViewGroup mView; public LayoutProxy(View view) { 
mView = (ViewGroup) view; } public int getWidth() { ViewGroup.LayoutParamslp = 
mView
.getLayoutParams(); return lp.width; } public void setWidth(int width) { 
ViewGroup.LayoutParams lp = mView.getLayoutParams(); mView.setLayoutParams(new 
ViewGroup.LayoutParams(width, lp.height)); } public int getHeight() { 
ViewGroup.LayoutParams lp = mView.getLayoutParams(); return lp.height; } 
public void setHeight(int height) { ViewGroup.LayoutParams lp = mView
.getLayoutParams(); mView.setLayoutParams(new ViewGroup.LayoutParams(lp
.width, height)); } public int getLeftMargin() { ViewGroup
.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) mView
.getLayoutParams(); return lp.leftMargin; } public void setLeftMargin(int 
margin) { MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams
(); lp.setMargins(margin, lp.topMargin, lp.rightMargin, lp.bottomMargin);mView
.requestLayout(); } public int getTopMargin() { MarginLayoutParams lp = 
(MarginLayoutParams) mView.getLayoutParams(); return lp.topMargin; } public 
void setTopMargin(int margin) { MarginLayoutParams lp = 
(MarginLayoutParams) mView.getLayoutParams(); lp.setMargins(lp.leftMargin, 
margin, lp.rightMargin, lp.bottomMargin); mView.requestLayout(); } public 
int getRightMargin() { MarginLayoutParams lp = (MarginLayoutParams) mView
.getLayoutParams(); return lp.rightMargin; } public void setRightMargin(int 
margin) { MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams
(); lp.setMargins(lp.leftMargin, lp.topMargin, margin, lp.bottomMargin);mView
.requestLayout(); } public int getBottomMargin() { MarginLayoutParams lp = 
(MarginLayoutParams) mView.getLayoutParams(); return lp.bottomMargin; } 
public void setBottomMargin(int margin) { MarginLayoutParams lp = 
(MarginLayoutParams) mView.getLayoutParams(); lp.setMargins(lp.leftMargin, 
lp.topMargin, lp.rightMargin, margin); mView.requestLayout(); } } }

And the error:

FATAL EXCEPTION: main java.lang.ClassCastException: 
android.view.ViewGroup$LayoutParams 
cannot be cast to android.view.ViewGroup$MarginLayoutParams at com.test.data
.ContactListCursorAdapter$handleClickListener$LayoutProxy.getLeftMargin
(ContactListCursorAdapter.java:135) at com.test.data

(ContactListCursorAdapter.java:94) at android.view.View.performClick(View
.java:4084) at android.view.View$PerformClick.run(View.java:16966)

What am I doing wrong and why would setting the margins just not work after 
setting a width?

[android-developers] Re: ClassCastException of LayoutParams to MarginLayoutParams after setting a view's width

[RichardC]

The error is in here:

public int getLeftMargin() { ViewGroup.MarginLayoutParams lp = (ViewGroup
.MarginLayoutParams) mView.getLayoutParams(); return lp.leftMargin; }

mView.getLayoutParams()
http://developer.android.com/reference/android/view/View.html#getLayoutParams()
returns a ViewGroup.LayoutParams 
http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html
not a ViewGroup.MarginLayoutParams

Re: [android-developers] Re: Wrong apk starts-up

[Nicholas Campion]

I have seen this, historically, on older phones using HTC's sense ui. The 
application launcher would cache the invokable target using properties of 
the AndroidManifest. It seemed to eventually go away, specifically if the 
device was restarted. I noticed this specifically when we changed the name 
of the Application class on these devices.

Is it possible you are hitting that issue?

[android-developers] Architecture for App gathering info

[vnv]

Hi,

could anyone help with architecture of application that would gather info 
from sensors and send it or save it to database.

My idea was to make service that would gather data from 
GPS,accelerometer,orientation and send it to my web service while also 
saving it to database on phone.

Service would run in background and fronted (Activity) would be used to 
communicate with service (ie. shut it down or start it) , show data from 
service.

Is this good approach?

What are means of communication with activity from service? (that are fast 
enough for this type of task)

Thanks for help.

[android-developers] Drawable Query

[Darryl Griffiths]

I am working on a simple animation using the animation-list attribute.  I
have all my sequenced images in the drawable-xhdpi folder and the first
line of my XML looks like this:



To keep things tidy, I decided to create a new folder called "seq" inside
of the drawable-xhdpi and moved my images inside.  Of course I got errors
in my animation.xml file, so I changed the first line to:



Still showing an error so could someone help.  Thanks.

That's a question for the Play Store team -- they do not monitor this
list as far as we are aware.

[android-developers] Re: Interfacing android device with external device using bluetooth.

I think I am correct in saying that this cannot be done using the Android 
SDK (or NDK).  However, if you are building your own device then the AOSP 
groups may be of some help:

[android-developers] junit classes in live Webkit code

[William Ferguson]

I just received the following crash report

java.lang.NoClassDefFoundError: junit.framework.Assert
at android.webkit.WebViewCore$WebCoreThread.run(WebViewCore.java:658)
at java.lang.Thread.run(Thread.java:1019)

This is for Gingerbread (2.3.6). Frankly I couldn't believe that a test 
class was burnt into and being used by a production class. I wonder whether 
they really meant to use the Java "assert" statement instead and hope it 
has been fixed since. The Junit Assert class shouldn't be used outside of a 
test harness. 

Has anyone else seen anything similar?

Incidentally, I'm familiar with this procedure and the request to 
transfer the app MUST come from BOTH the involved developers' accounts 
for the Play admins to take action. (Presumably two very similar emails 
with just different sender, submitted around the same time.)


I'd suspect a working day or two for it to actually be moved is normal. 
So far I've only prepared for this, not actually done it.

Re: [android-developers] Buttons in ViewPager pages: Problem swiping/dragging pages when finger starts on top of Button. How can I fix this?

[Streets Of Boston]

The targetSdk is 11.
This is our hierarchy:

-ViewPager 
  | 
  +-NoSaveStateFrameLayout
   | 
   +-ProfileGridView
  |
  +-ProfileGridViewRow
  |
  +-FrameLayout
|
+-TextView

Note that ProfileGridView contains one or more ProfileGridViewRows which 
contains one or more clickable TextView  (i.e. our buttons).
The ProfileGridView and ProfileGridViewRow are custom LinearyLayouts: The 
have their own measure and layout-logic. These two subclasses don't have 
any method or logic to capture or handle touch-events.

Thanks!

 Buttons (or clickable TextViews). When I set the buttons to 
 'setClickable(false)', swiping the ViewPager to another page works fine 
 all 
 the time.

 However, when the buttons are clickable (OnClick listener is set), the 
 ViewPager won't do anything if the user put his or her finger down on the 
 button when he or she starts a swipe or scroll. If the user swipes, the 
 button 'eats' all the touch-events (MotionEvents).

 Is there a convenient way to make these buttons/textviews clickable and 
 make the ViewPager swipe even if the user puts his finger on a button 
 initially?
 (I'd like to avoid hacks and using GestureDetectors if possible)

 Thanks!

[android-developers] Re: Interfacing android device with external device using bluetooth.

[bob]

 

You will most likely want to use Bluetooth or Wifi.

[android-developers] Re: Layout is corrupted with graphics from another layout? Only at runtime, only on a certain device.

[NickL]

Good suggestion, but the build works perfectly on all devices but the 2.2 
HTC.  If it occurs and the layout is corrupted, I can make the problem go 
away by rebooting the phone.  Sounds like some sort of memory corruption 
that Android is sensitive to.

[android-developers] Lucky patcher - how to protect

[Gabriel Simões]

Hello,

It has been sometime now since this app was first saw in town but I still 
can´t find much about how it bypasses some key java resource protections.
LVL patching has been there for quite sometime and isn´t the problem here 
at all: receiving wrong validation information from dalvik seems to be the 
issue, which no code based on those can help.

While I really don´t expect to find a magic formula to fight this (and keep 
the dogfight between developers and crackers), I´d like to know if anyone 
has found/figured out information on how it works so we can start thinking 
about fighting back strategies.
Any news to be shared?

Thanks,
Gabriel Simões

[android-developers] [Android-developers]:need help in creating bluetooth file transfer app. urgent

[akash roy]

i am currently on a project and i need to share files from one device to
another with the help of bluetooth. so i thought of changing the codes from
the bluetooth chat demo that is available in android developer's site .
actually i need to simply send a text file . but i am getting some issues
in that code due to which i could not rectify my problem. so if any of you
can send me a sample for sharing files using bluetooth then i think then it
could be a great help to me.

Thankyou

Re: [android-developers] Re: Listview - Header , footer issue

[Jovish P]

Sorry , we are not able to understand you fully. Wht is the difference
between the first approach we explained in the mail and the approach u
suggested .  Up to our knowledge both are same . Wht difference it is going
to make if u inflate every view programmatically instead of using xml ?

[android-developers] Rotation Vector Sensor - anyone using it? (issues w/ Galaxy Tab 10.1)

[Adam Ratana]

Hello, I am working on improving an augmented reality app I have, and part 
of that improvement involves making use of the sparsely-documented rotation 
vector sensor, which seems to integrate the magnetometer, accelerometer and 
gyroscope rather well on several of my devices.  This will serve to replace 
the classic magnetometer + accelerometer fusion + filtering that we've had 
to do ourselves previously.  Making use of this seems to be a huge 
improvement, and I'd love to deploy it as soon as I can get the feeling it 
will be safe for most devices.

The problem I am running into is, on my Galaxy Tab 10.1, which just got ICS 
4.0.4, the Rotation Vector Sensor does not seem to be working consistently 
when dealing with screen rotation compensation. North seems to change 
places depending on how the screen is oriented, even after calling 
SensorManager.remapCoordinateSystem(), whereas all is good on the Nexus 7 
and Galaxy Nexus, and several other gingerbread + devices, that is, North 
is consistent, after calling SensorManager.remapCoordinateSystem().

I haven't really seen much when doing google searches for anyone really 
making use of this or running into this sort of thing, so if anyone here 
has any experience, please get in touch.  Or, if you have some of the less 
popular devices which have gingerbread+ and are interested in helping 
evaluate a proof of concept/test APK, let me know.

Adam

[android-developers] Re: Polling at regular intervals in Android

[Archana]

Hi,

Please let me know if the following is okay:
1. Fire alarm for every 5 minutes using Alarm Manager
2. Response- Start a service that polls server
3. After polling, new alarm is set and service shuts down.
Should I also use WakeLock in my code? 
https://github.com/commonsguy/cwac-wakeful

Thank you!
