[android-developers] Problem with writing files to internal memory (not visible on file browser on ICS)

[Dirk Vranckaert]

I have a problem when I try to write a file to the device's SD-card.

It's an export in CSV format that I save to the directory /Android/
data/eu.vranckaert.worktime/files/worktime/ and the name of the file
is "export.csv" in this case.

File exportDir = ctx.getExternalFilesDir(null);
File file = new File(exportDir, "export.csv");
//Already had the issues before I was applying these
permissions!
file.setReadable(true, false);
file.setWritable(true, false);
file.setExecutable(false, false);
boolean fileAlreadyExists = file.createNewFile();
if(fileAlreadyExists) {
file.delete();
file.createNewFile();
}
FileWriter fw = new FileWriter(file);
BufferedWriter bw = new BufferedWriter(fw);
bw.write(result.toString());
bw.close();
fw.close();

I tested this code and here are the results:
1) Emulator 2.3 with SD => no problem
2) Emulator 3.2 with SD => no problem
3) Emulator 4.0 with SD => no problem
4) HTC Hero (running 2.3.3) with SD => no problem
5) Samsung Galaxy ACE (running 2.3.x) with SD => no problem
6) Samsung Galaxy Nexus (running 4.0) with the 16 GB build-in SD =>
problem!!

The problem I have is that I cannot see the file that is created:
a. when I use a file browser on the device
b. when I connect the device to my windows computer (windows 7)

However I can see the entire directory structure created, just not the
files! I already had this problem before when I was not applying the
permissions, I just thought to try that without any luck.

But I noticed something else, when launching DDMS I can see the file
and download it from the device on my computer.
However this is not user-friendly so I want to have my export working
on ICS as well witouth any hacks for the user to access his exported
files.

I also tried to change the directory where it's saved, instead of the
"/Android/data" directory structure, I set it up to save on my SD-card
to the "/worktime/" directory, but that doesn't work either!

You can check out the DDMS and explorer screenshots I took attached to
the issue on google code: code.google.com/p/worktime/issues/detail?
id=84#c4

Does anyone know what I'm doing wrong or can do better to have this
working?

Kr,

Dirk

[android-developers] Re: Invert and entire Bitmap

[hhenne]

You can make a Paint and setXfermode to XOR (PixelXorXfermode) and the
draw a solid rect on the bitmap. It will invert every bit - so when
you do it once more you are back to non-inverted. I am doing so in my
keyboard (http://www.maxikeys.com) to invert pressed keys - the room
between the keys have the color 50% grey, which will not change, when
being inverted.

[android-developers] Activity Life Cycle Issue on Orientation Change

[Jim Duda]

I'm developing an application on API 2.2 (Froyo).   I'm having a
problem with myListActivity when I do an orientation change from
Vertical to Horizontal (F11 on emulator).  After the orientation
change, I go through onDestroy and onCreate as expected.  After the
onCreate, the application restarts and I get my first screen.  My
ListActivity changes list adapters as the user makes various
selections.  Each time a selection is made, a new list adapter is
created, setListAdapter( ) is called, followed by
notifyDataSetChanged( ), which results in the new list adapter
displaying the new data on the screen.

For some reason, after the Orientation change, only the first list
adapter works.  After making new selections, creating a new list
adapter, and calling notfiyDataSetChanged( ), I never get the next
display.  It is as if the notifyDataSetChanged( ) isn't working after
the Orientation change.  I have emulated this theory by altering my
app by not calling notifyDataSetChanged, and I get the same behavior
in lieu of doing the orientation change.

I have tried a copy of later APIs, and I get the same results.

I do have some static classes in my application, I tried to null them
out in onDestroy( ), thinking they were causing problems on the return
through onCreate( ), but that didn't help.

Anyone have some advice on what I might be doing wrong?

Regards,

Jim

[android-developers] Android ICS 4.0 Placing Flash WebView into full screen calls hideAll Method?

[David Venezuela]

http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.1_r1/android/webkit/PluginFullScreenHolder.java#PluginFullScreenHolder.setContentView%28android.view.View%29

public void show() {
// Other plugins may attempt to draw so hide them while we're
active.
if (mWebView.getViewManager() != null)
mWebView.getViewManager().hideAll();

WebChromeClient client = mWebView.getWebChromeClient();
client.onShowCustomView(mLayout, mOrientation, mCallback);
}

void hideAll() {
if (mHidden) {
return;
}
for (ChildView v : mChildren) {
v.mView.setVisibility(View.GONE);
}
mHidden = true;
}

Its basically hiding my whole WebView on full screen selection now
this does not happen in the default browser and this methods are not
accessible. How can I fix this?

Best Regards

David

[android-developers] Constraining FrameLayout dimensions (greater than viewport) using LayoutParams after scaling children

[momo]

Sorry about the poor title - it's hard to summarize the issue in one
line.

I'm working on a map tiling system for small-scale maps (imagine
building interiors), with zoom and pan functionality.  Most of this is
working properly, but after a scale operation I try to limit the
scrollable area using LayoutParams and think I'm doing it wrong, as
the behavior is unpredictable (to me, at least).

There's a "main" container (FrameLayout).  On the top layer are the
controls and other elements that don't move or scale.

The bottom layer is another a FrameLayout with scrolling enabled on
both axes (a slightly modified version of
http://blog.gorges.us/2010/06/android-two-dimensional-scrollview/).
This layer has 2 layers - an ImageView that displays a low-res version
of the map on bottom, and another FrameLayout with a "grid" of
ImageView tiles positioned with top/leftMargin.

Tiles are rendered on-demand based on what tiles would be visible (on
screen), so the low-res bottom layer is visible when scrolling or
zooming (before the final viewable area is calculated and the
appropriate tiles are rendered).

Markers and other elements are contained in another FrameLayout in the
scrollable View, above the one that has the 2 map layers (which scale,
together)

So the heirarchy looks like this:

main container
scrollable layer
maps layer
low-res image
tile container
markers layer
controls layer

During a pinch event, I "zoom" the maps layer (inclusive) by
overriding onDraw and using canvas.scale, and maintain scroll position
using getFocusX/Y.  This all works fine.

The issue is that I need to re-assign the total scrollable width and
height of the scrollable layer, so that scrolling stops at the edge of
the (scaled) maps.  Initially this works properly, but after a scale
operation everything goes haywire.  I've tried using
LayoutParams(originalMapWidth * scale, originalMapHeight * scale) on
every possible combination of the layers to be affected (scrollable,
maps, low-res, tiles), but it never lays out correctly - the closest
I've gotten is that the width does get properly constrained by the
height does not.  If I just apply the new LayoutParams to the maps
layer, clipping occurs (it looks like the scale factor is being
applied twice - this appears to be a red herring and I tried to
compensate with simple math (dividing the width/height by the scale,
etc) and it never got to a usable point.

In looking at the source of the one 3rd-party component I'm using (the
2D scrollview linked above), it looks like the issue might be in
there, but my attempts to force it to work with my setup have failed,
and I'm not eager to tackle recreating that feature (but I will if I
have to).

I've got a fairly slimmed down version where I'm trying to target just
this issue (no controls, no markers, a single tile set, etc), but it's
still pretty long and didn't seem appropriate for a post, but I'm glad
to share whatever code would be helpful.

Am I missing something obvious about how layouts work?  I've been
beating up on this one (seeming small) issue for days now, and am
making no progress.  Any insight would be very much appreciated.

[android-developers] getResponseCode

[Androiding Newbie]

Hi guys,

I sorta have a problem. I m currently programming a Android Code for
passing information to a server using httpsURLConnection. However I
have problems when I execute the command: int rc =
httpsUrlConnection.getResponseCode();

It always takes at least half a minute to process this method since I
m sending relatively big strings back. Is there any way to speeden
things up? I tried to leave this command away but then nothing works,
the server does not receive any information.

This is my Code:
if(isOnline(context))
{
byte[] bytes = soap.getBytes();

System.setProperty("http.keepAlive", "false");

SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, new TrustManager[] { new 
MyTrustManager() },
new SecureRandom());


HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());
HttpsURLConnection.setDefaultHostnameVerifier(new
MyHostnameVerifier());
HttpsURLConnection httpsUrlConnection = 
(HttpsURLConnection) new
URL(APIData.getURL()).openConnection();

TelephonyManager telephonyManager = (TelephonyManager)
ActivityStack.peek().getSystemService(Context.TELEPHONY_SERVICE);
String imei = telephonyManager.getDeviceId();


httpsUrlConnection.addRequestProperty("Authorization", 
"Basic " +
Base64Encoder.encode(imei + ":" + imei));
httpsUrlConnection.addRequestProperty("Content-Length", 
"" +
bytes.length);
httpsUrlConnection.addRequestProperty("Content-Type", 
"text/xml;
charset=\"utf-8\"");
httpsUrlConnection.addRequestProperty("SOAPAction", 
"http://
tempuri.org/IDataUploadWS/UploadSmartPhoneData");

httpsUrlConnection.setRequestMethod("POST");
httpsUrlConnection.setDoInput(true);
httpsUrlConnection.setDoOutput(true);
httpsUrlConnection.connect();

OutputStream output = 
httpsUrlConnection.getOutputStream();

output.write(bytes);
output.flush();
output.close();

int rc = httpsUrlConnection.getResponseCode();
Log.i("", "APIConnection.sendSOAP(...): ResponseCode = 
" + rc);
Log.i("", "APIConnection.sendSOAP(...): ResponseMessage 
= " +
httpsUrlConnection.getResponseMessage());

httpsUrlConnection.disconnect();

result = checkResponseCode(rc);
}

[android-developers] Does icecream sandwich 4.0.3 enforces more restrictions for application developer in threading usage ?

[Pritam]

I am working on an application that was designed for tablet
(specifically tested well on Motorola Xoom and Samsung Galaxy Tab
10.1). The O.S. which was used was HoneyComb.

Recently after updating the O.S. to official Icecream Sandwich 4.0.3,
that was received as notification update, I find the application is
not at all well.
It lags in performance, gives frequent ANR ( Application not
responding ) dialogs.

While I understand the ANR are related to performing more work in the
UI thread, i need to know does this new android version 4.0.3 enforces
more strict restrictions on number of threads that runs in
background ? Or killing them as the activity exists that started it ?

Application uses threads exclusively to load images from server in
list views. Switching between screens makes each individual image
holder to start a new thread for its loading.
Retesting it on Honeycomb makes it work perfectly fine but not with
4.0.3, Why ?

Question is on whether icecream sandwich 4.0.3 makes changes in this
area at O.S. level handling of threads or activity lifecycle for
developers ?

Re: [android-developers] Re: Fail to connect to camera service <- Camera.open();

[Raghav Sood]

The camera can only be used by one application at a time. You must release
it when you are done with it, so that you may use it again. The other
applications can still use the camera as your app force closes, which frees
up the camera.

Thanks

[android-developers] Re: TextView scroll in an activity.

[Put_tiMe]

Ok, I got it to work.
I HAD to add a scroll view to the text view.
 
http://schemas.android.com/apk/res/android";
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical"
 android:isScrollContainer="true"
 android:scrollbars="vertical|horizontal"
 android:scrollbarStyle="outsideOverlay" >
 

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="text|textMultiLine"
android:scrollHorizontally="false"

 
And for the word wrap to work, see the attributes for TextView above.

Re: [android-developers] How to add e new element to public.xml?

[Dianne Hackborn]

By making it public you are declaring a final resource ID for it that can
not change.  You should not be doing this unless you are building the next
API level of the platform.

[android-developers] How to add e new element to public.xml?

[hongbosb]

I am modifying framework of AOSP. And i have declare a new style in 
styles.xml under framework/core/base/res/res/values. This style hasn't been 
set to hide. When i execute "make update-api" in root directory, it won't 
add this new element to public.xml. Shoud i add this new entry to pubic.xml 
by hand? i don't really want to do this because it contains a attribute 
that is the memory address of this element. It may change later.

There are also apps that let your share it via Samba (Windows file sharing),
but you need a rooted phone.

[android-developers] LVL Reasons for answering differently for real users and test accounts

[Gabriel Simões]

Hello!

I´m facing an issue I haven´t before and I really don´t know what may
be causing my issues.

I  have 2 apps implementing LVL. I´ve never faced big issues with LVL
before but now, for some unknown reason my users started complaining
that after updates they are not able to validate licenses anymore.
If I use the same apk and register the user market account as a test
account, then it works as expected. Everything works fine on my device
(using the default test account - developer account).

Are there any reasons for an app to answer in different ways for real
users and test accounts?
I´ve confirmed the users have bought the app and market has validated
their licenses before.

Things I´m thinking of:
- I´ve changed my development environment recently. After changing my
notebook I´ve had issues signing my apks: went back from JRE 7 to JRE
6 and everything seems fine.
- Any reasons why Android Market should stop validating users after
updating from one version to another? I´ve double checked
LICENSE_OLD_KEY using test accounts and it is working as expected.
- Will I need to create a new user, attach someone else's credit card
and download my own app so I can debug market answers?

Please, help!
Thanks,
Gabriel Simões

You need to make sure that whatever CA issues the certificate
you intend to buy is found trusted by your device. Some CAs
have a trial certificate with a limited validity (a week or so),
that you can use to do actual testing. Or, you can list
the trusted certificates on the device with something like
this tool (or write your own):

https://market.android.com/details?id=info.guardianproject.cacert

and check that the CA certificate is trusted by your device.

That said, knowing that VeriSign got hacked multiple
times with unknown consequences, you might as well
use a self-signed certificate. It is a bit more work to implement,
but not that much.

You should never, ever see a resource qualifier like that.  That is,
frankly, insane.

Also mixing density with screen size almost certainly means you are doing
something on.  I can guarantee that you that there will be device
configurations in the future that break with such things, because density
has *nothing* to do with screen size.

The first this is please, please read the documentation and my blog post
here:
http://android-developers.blogspot.com/2011/07/new-tools-for-managing-screen-sizes.html

The blog post includes examples of how to use the new selectors in a
compatible way with older devices.

Also, yes, the large size bucket is problematic, as the blog post
discusses.  There isn't anything we can do to help this for older versions
of the platform. My suggestion if you need to deal with this is to just
fall back on doing it programmatically -- define two layouts that are not
qualified by screen size, and when your code runs look at the actual screen
size (converted to dp units) and pick the one to use based on that.

Or alternatively, just forget about large, code against xlarge and the new
-sw qualifier, and make sure your normal layout resizes reasonably when
running on a larger screen.

*IF* (and I stress **IF**) I understand correctly, the shutter doesn't
actually close, as such.  The preview image you see is using the camera's
sensor.  When you take a picture, it just records the displayed image.

My suggestion would be to use a very good shield to cover the lens
(perhaps a deep black towel with the device resting on it ... in a
tightly sealed box).  It wouldn't be perfect, but it might be as good
as you can get.  Then, you could either use video mode rather than camera
mode, and analyze each frame, or take repeated photos using the longest
exposure time you can.  Then do your analysis using (forgot the name) the
process NASA, JPL, etc. use for deep space imagery, where they take
multiple images of the same object and let the computer determine, by
comparing ALL of them, what's real (i.e., stays in the image) and what's
noise (moving or otherwise not constant).

Hopefully someone here can tell you how to do it the right way...but if
not, maybe this will help.

Btw, to get a longer exposure, if your device supports it, use the
SCENE_MODE_NIGHT parameter (see "Camera.Parameters" in the developers
guide (http://developer.android.com) for more information.

Later,
   --jim

PS:  I'm doing the studying right now, but am planning on working on a
 photo app, myself.  There are a lot of features that I just can't
 find in any of the existing camera apps, most of which I'm fairly
 certain will prove to be easy...or at least, not insanely difficult.
 The others are probably impossible to do without an SLR or DSLR.

I can tell you that I created an emulator with Android version 2.3.3,
told it to be 1280x800, and it picked up my very specific layout that
I stored in layout-large-port-xhdpi-1280x800.  Was that a fluke?  I
don't know.  But we haven't had any complaints from Note users,
whereas if the old layout was used, we would definitely receive some
complaints.

I think Samsung was aware of the problems with the way that the Note
works with some apps, because my company was directly contacted by a
representative from Samsung who helped us work out the layout issue
with our app on the Note.

[android-developers] Re: good android blog

[Ali Chousein]

When promoting own work, it's a good practice to avoid using articles
like "good", "great", "excellent", "mind-blowing" etc. Posting the
relevant link is usually considered to be enough. It's up to the
audience to choose adjectives for describing the contents of the link.

Never mind. This is related to custom attributes in a library project
which is still unsupported.

[android-developers] progressBar for percentage of file-uploaded

[Farhan Tariq]

Hi guys,

I have written a piece of code in an application that uploads a file to a
location, if provided with path of a file. What i am missing is a way to
show the percentage of file uploaded. I am using apache's http library for
this purpose (found it on the internet). The relevant code is here:

final File file = new
File(filePathToUpload);
final HttpClient client = new
DefaultHttpClient();
...
...
String postURL= Constants.BASE_URL;
HttpPost post = new HttpPost(postURL);
FileBody bin = new FileBody(file);
MultipartEntity reqEntity = new
MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("myFile", bin);
post.setEntity(reqEntity);
client.execute(post);

I need help/suggestions with how do, if i can, get an output stream, if
that would help, from the HttpClient and get the number of bytes sent? I
need to show the percentages on my progressBar...
Is it even possible with httpClient?

If that's the line that causes the problem, and the problem is "null
pointer", then basic Java knowledge tells you your "spinner" variable is
null. If you read Dallas' response, he already gave you the answer.

The line that causing the problem is:

spinner.setAdapter(spinnerArrayAdapter);

The rest of the code is pasted above.

I've used other programs that use spinners, this one doesn't want to
work.

[android-developers] ADT 16 crashes

[theSmith]

Eclipse 3.6.2
ADT 16.0.1
OSX 10.6.8

I'm in the process of creating a new library project out of a previous
project and am now trying to create a project that depends on it.
This isn't the first time I've used Libraries and have several that
work just fine.

When trying to build the project (not library) Eclipse encounters an
error (below).  Has anyone seen this before and know how to fix it?

Errors occurred during the build.
Errors running builder 'Android Pre Compiler' on project 'Photomash'.

[android-developers] Comparing Ice Cream Sandwich with iOS 5

[swingyang yang]

In this document, I am trying to compare the APIs of ICS with those of
iOS 5. So, the comparison is from the point of view of the developer.
And, I am looking only at the public APIs documented on the Android
SDK web site. I know there are other APIs in the source code and they
may be used by some applications. But if they are private it means
they may change in the future and the applications using them would
break.

Both systems are huge and not always very well documented. The best
way to check the assumptions is by writing code and experimenting. But
it is taking time and I don't have it. I used to develop for iOS but I
stopped at iOS 3.0 and only explored a few domains. I developed a bit
for Android and stopped at Froyo. So, obviously this comparison is
containing mistakes. I am sure I have missed some features (specially
on ICS side). I hope my readers will help me to improve the
comparison. I am far from being an expert at all of those domains. So,
this document is first to help me improve my understanding and also
for the non-experts who'd like to know more about each OS.

So, please, don't be too harsh with me if you find some big
mistakes :-) Because I am sure you'll find some.

Comparing ICS and iOS 5 is a risky thing to do :-) So, for the
trollers and zealots : don't waste your time and mine. You'll be
censored heavily. Freedom of speech means you can express yourself on
your blog and I don't have to read it. It does not mean you can say
anything here.

This document is sometimes using the word «OS» for Android or iOS. Of
course, it is incorrect since they are distributions. But, most people
are speaking like that so the document is following the general
trend.

I have tried to avoid copy/pasting extracts of the OS documentations
but in some cases it was too tempting.

Finally, this document will be improved based upon the comments. So,
I'll track here the list of changes I have made

sorry , the rest of content as following:

[android-developers] Multiple ProximityAlerts

[Georg Kaspar]

Dear group,

I'm trying to set up a mapping application that allows to track down
multiple POIs where different kinds of location based information
(images, texts, audiofiles) are provided.
For each point, a ProximityAlert is added to the LocationManager with
a
PendingIntent:

private void addProximityAlert(double latitude, double longitude) {

Intent intent = new
Intent("org.something.ProximityIntentReceiver");
PendingIntent proximityIntent =
PendingIntent.getBroadcast(this,
0, intent, 0);

locationManager.addProximityAlert(
latitude, // the latitude of the central point of the
alert
region
longitude, // the longitude of the central point of the
alert region
20, // the radius of the central point of the alert
region,
in meters
-1, // time for this proximity alert, in milliseconds, or
-1
to indicate no expiration
proximityIntent // will be used to generate an Intent to
fire when entry to or exit from the alert region is detected
   );

   IntentFilter filter = new
IntentFilter("de.eulegdi.rieselfelder.ProximityIntentReceiver");
   registerReceiver(new ProximityIntentReceiver(), filter);
   int g = 0;
}

I found this Example on
"http://www.javacodegeeks.com/2011/01/android-proximity-alerts-
tutorial.html",
it makes use of ProximityIntentReceiver class (an extension of
BroadcasReceiver).

Unfortunately, when I reach proximity of a POI all Intents are fired
at
once though each one is defined using different coordinates. What am I
doing wrong? The example only uses one POI at a time though more than
one should be possible!?

Any help is appreciated! Thanks & best regards,
Georg

[android-developers] shutter closed and exposure time

[Rok]

Hi!

I am working on an application for astronomy and I would like to
measure so called dark current of a CCD (in electrons per second).
To do this I have to take pictures with shutter closed and at
different exposition times.
Is there a way to do this with android (or is there another way to get
dark current)?

Thank you in advance.

[android-developers] Re: Source not found/ArrayAdapter

[drac94]

"Source Not Found" means you haven't linked the Android source code
into Eclipse, and you are trying to step into that code. The debugger
can't step into it if the source isn't available to it.

So, that is not the real problem for your spiner. Check the log cat
and try to locate the first error line, then paste it here for see
what is the problem, and if you can paste some of your code will be
easier to help you.

[android-developers] Multi-choice alert dialog

[Juxtenia]

As part of an app I'm writing I've got to get a multi choice dialog
where the user can select people who are travelling on a holiday.
However when i try to initiate this dialog it never appears and if I
try to do anything else I get ANR. The initialising code in the
onCreateDialog(int id) method is as follows:

case PEOPLE_CHOSING_DIALOG:
AlertDialog.Builder builder = new 
AlertDialog.Builder(this);
builder.setTitle("Select Travellers");
builder.setMultiChoiceItems(peepses, results, this);
Looper.prepare();
AlertDialog alert = builder.create();
return alert;

I know this code is being run but the dialog is not appearing. peepses
contains the names of the people and results is an all false array of
boolean. The class this is being run in is WorldActivity which
implements the OnMultiChoiceClickListener interface.

Any help would be much appreciated, thanks in advance.

Re: [android-developers] voice input for people with tremors (or large fingers)

[Megan Clark]

There is an app called Vlingo Virtual Assistant -- I'm not sure it
will help but it might save your brother some frustration until
someone comes up with something more accessible. I played with it on
my phone a few months ago, but I can't remember much about it other
than nice voice utility and big buttons.

Good luck!

Re: [android-developers] Re: Source not found/ArrayAdapter

[Dallas Gutauckis]

Try moving your call to setContentView before the call to findViewById. If
you don't have layout, findViewById won't find a view. I'm assuming your
NPE is on that spinner.setAdapter(...) line.

[android-developers] Memory usage details in Taskmanager

[avinash kumar]

Hi,

My RAM usage memory in TaskManager shows two values.What do those two
values signify?
Are they the numbers for Total free memory/Total memory or Used memory/
Total memory?

Also when I do a cat /proc/meminfo, the memory usage details that I
get are very much different to the one in Task manager.
What is the reason for that or am i comparing two different memory
usage details here?

Regards,
Avi

[android-developers] ScrollView in SYSTEM_TYPE_ALERT is blurred

[Drew]

I have an android app that displays an system alert from a service:

WindowManager.LayoutParams params = new
WindowManager.LayoutParams(WindowManager.LayoutParams.FILL_PARENT,
WindowManager.LayoutParams.FILL_PARENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM, PixelFormat.OPAQUE);

((WindowManager) getSystemService(WINDOW_SERVICE)).addView(view,
params);

I have set view to a GridView, Scrollable TextView, and a Gallery and
on all of them if I scroll the images/text blend together. Everything
is blurred together. It is as if the new image/text is drawn on the
screen but the old image/text is not removed. Any idea on how to fix
this? Does anyone have an example of a TYPE_SYSTEM_ALERT where the
content is scrollable?

[android-developers] Re: Using ViewPager with dynamic view sets

[HeneryH]

tatebn, did you ever solve this problem?  I have been going crazy trying to 
dynamically add views to a viewpager based on database items.

If I find one more sample with three statically defined views each adding a 
textview with the index I will go crazy!

[android-developers] GPS - SMS - Mock Location

[Hohorlan B]

I have this code for my project. (Not mine, but I revised it so it
will suit my needs.)

http://pastebin.com/Tn4guLNR

My Project is about a specific GPS hardware that will send GPS
position to the Android Phone. The phone will have to display the
location via Offline maps like mapdroyd. This program, when the button
is clicked, it will display the offline map. The gps mock location
will then be turned on. So the map will display the Mocked location
from SMS.

However, my program keeps on Showing Force close. Can someone help me
for this?

[android-developers] Application to allow selected application to connect to the internet via 3G

[Nwanna Anthony]

I have successfully written the android code that will totally disable 3G 
on a device. What I want to do next is to edit the code so that only 
selected application can access the internet via 3G while others cannot.
My application is just like the Droid wall but with some difference. I have 
been working on this application for quite sometime because I just started 
learning android some months back.
Please I need help with a line code or references to a web link that I can 
get an Idea.
Am using this as my final year project and the last part of the code 
modification has been holding me back.

[android-developers] I've been making games for a while now but how do I make them successful?

[Pedro Gabriel Fonteles Furtado]

I have just released this game:
https://market.android.com/details?id=monster.puzzle

It has okay visuals, okay gameplay, I think it even hits some
interesting key words. Yet it's not getting a lot of downloads.

I used to think you need to hit popular key words to be successful in
order to have organic growth, but that doesn't seem to be the case.
The popular key words are drowned with applications so you can't rank
high on searches.

How do you make an fresh new game app successful? Do you have to beg
for reviews from different websites?
Do you have to hit popular key words that don't have a lot of apps?

What's the trick?

Thank you for your time!
