[android-developers] wifi splash page not disappearing

[Kyle Lam]

Hi all,

 

I am trying to add a splash page/ wifi landing page/ wifi agreement page 
(or whatever the name is) to my network by modifying my dns server.

We know this is not the so call "correct" way to do it, and will not block 
attacks in a meaningful way. (as they can always use a better DNS server)

 

Here is how my implementation works:

1) DHCP point device to use my DNS server

2) DNS server reslove all request as an local ip address, in which it host 
a web server for the agreement page

3) After user agree to the terms, DNS server will start resloving the 
request correctly, thus, user will be able to get to the web

 

It works on computers, however, when I tested it on Android devices, here's 
what happen

1) connect Android to wifi network

2) Android tried resolve a number of sites to determine if the system has 
internet connection

3) DNS server reslove all these request as a local web server's ip address, 
with ttl=1

4) splash page comes up on iPhone

5) user click I agree, and DNS server starts giving out correct ip, the 
page also redirect user to an internet address

These all works as expected, however, the splash page does not go away 
after connect.

The user would have to click the option: use this network without internet 
access (or something like that) to dismiss the page. (Clicking home here 
will results in disconnecting from the network)

 

I wonder if there is a special (javascript?) method I can call in the page, 
or some package I need to send to the device?

 

Thanks a lot,

Kyle

[android-developers] Sketching out the Graphical Interfance

[android-developers] UI Automation

[Kyle Wolff]

We are using SeeTest and I just started using appium for our UI Automation 
tests. 

I was curious into if there is a way to show custom values if it is a 
custom widget when the inspectors run on a view. 

Right now we can see the basics:  

*content-desc:* 

*type:* 

*text:* 

*index:* 

*enabled:*

*location:* 

*size:* 

*checkable:*

*checked:*

*focusable:*

*clickable:*

*long-clickable:*

*package:* 

*password:*

*resource-id:* 

*scrollable:*

*selected:*

*xpath:*

I would like to add custom attributes here if our QA needs them. Is this 
possible? 

I found @ViewDebug.ExportedProperty and this works when using the Android 
Device monitor and look at View Properties but not using these automation 
tools.

Happy to provide more screen shots if that is helpful. I'm right at the end

[android-developers] Iterate Over JSONArray and update Arraylist Hashmap Android

[Kyle Phillips]

I create an `Arraylist Hashmap` (shown below) by parsing a JSON response 
from Google Places API. Than I take the id strings and send them to my 
server to look for users with matching ids in my DB. Any matches I return 
the users in a JSON response (shown below). 

Now what I need to do is iterate over the JSON response and count the 
number of ID matches and update the numbercheck value in the hashmap to 
the appropriate number. For example in the JSON Response there is 2 
occurrences of the id 339fd8e9a6aee4567764275e4d0827568fb499e5 so I would 
update numbercheck from null to 2 on Place 1. I'm not sure how to go about 
this. Should I parse the JSON response into its own map and than compare 
the two maps? Any help would appreciated. 

`Arraylist Hashamp Example:`

[
{
lastcheck=null,
id=339fd8e9a6aee4567764275e4d0827568fb499e5,

numbercheck=null,
name=Place 1
},
{
lastcheck=null,
id=d42061acd095772c3e646819fb47aea5b03e4705,
vicinity=1338NWHoytSt,
Portland,
numbercheck=null,
name=Place 2
}
]

`JSON Response Example:`

{
tag: userList,
success: 1,
error: 0,
placeMatches: {
userObjects: [
{

[android-developers] Saving Images to SD Cards on All Devices

[Kyle Dalrymple]

Hello all,

My app involves selecting an image from the device's gallery and then 
saving a smaller version of that image to a folder on the SD Card. The 
problem I'm running into is that some users are reporting that the images 
aren't getting saved to the folder. Most users, however, report that the 
app is working fine and I can't tell what is happening to these other few 
users. So far, the devices that are reported to be running into the issue 
are as follows: Huawei T-Mobile myTouch, Samsung GT-S5830i, HTC Evo 4G, and 
the Samsung Galaxy S2. I myself have a Motorola Atrix 2 and I've had no 
such issue.

My manifest has the tag in it already. Most of my code comes from 
stackoverflow solutions to get an image from the gallery and then save it 
to the sd card.

Getting image from gallery:

public void onActivityResult(int requestCode, int resultCode, Intent data) 
{
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) 
{
 switch(requestCode) 
 {
case SELECT_IMAGE:
 image_dir = getPath(data.getData());

 Bitmap myBitmap = decodeFile(new File(image_dir));

 resizedBitmap = Bitmap.createScaledBitmap(myBitmap, 
(int)(myBitmap.getWidth()/2), (int)(myBitmap.getHeight()/2), true);
 break;
 }
}
else
{
 image_dir = None;
}
}

Saving the image to the SD Card:

OutputStream fOut = null;
File file = new 
File(Environment.getExternalStorageDirectory()+/MyApp,imgname+.jpg);
fOut = new FileOutputStream(file);

resizedBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
fOut.flush();
fOut.close();

And this all seems to work out fine for most users, but for some users the 
image isn't getting saved. Could this be a permissions issue or some sort 
of setting I've overlooked in the code itself? Any help is appreciated.

Thanks,

Kyle

[android-developers] DatePicker in a fragment

[Kyle]

I am attempting to use a datepicker dialog based on the example at
http://developer.android.com/resources/tutorials/views/hello-datepicker.html.
This is obviously for an activity, but I'm trying to implement the
same functionality in a fragment.  Using the code from the example
won't work.  By this, I mean the following code snippet does not
actually open the dialog:

...
mPickDate = (Button) mRootView.findViewById(R.id.button_leave_date);

// add a click listener to the button
mPickDate.setOnClickListener(new View.OnClickListener() {
   public void onClick(View v) {
mActivity.showDialog(DATE_DIALOG_ID);
   }
});
...

After reading various sources online, I know showDialog is
deprecated and the recommendation is to use the DialogFragment.
However, is there an option to generate a date picker dialog with this
implementation?  I've been unable to find any good examples of anyone
trying this - so if there are resources available to merge the
(deprecated) example on the Android Developer web site with an actual
DialogFragment implementation, I would really appreciate it.

I would advise not using android:maxSdkVersion='12'.  In fact I believe it

[android-developers] Activities in Tabs

[Kyle]

I am creating an app which has 4 tabs. I have been following tutorials
like this one 
http://androidgenuine.com/?feed=rss2tag=tabhost-nested-activity-android
. That is how i set up my app, one main class that extends TabActivity
and 4 different tabs that extend ActivityGroup. so everytime i want to
add an activity to the tab i do something like this. This is not my
code its from the example.

Intent i = new Intent(this, ShowCity.class);
String city_name = (String)
getListAdapter().getItem(position);
i.putExtra(city_name, city_name);

// Create the view using FirstGroup's LocalActivityManager
View view = FirstGroup.group.getLocalActivityManager()
.startActivity(show_city, i
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();

 // Again, replace the view
FirstGroup.group.replaceView(view);

So by the looks of it, it creates a new Intent and makes it into a
View then replaces the tab view with this one. The problem is that
methods in the new Activity like Onback, onResume, and all the other
ones are not being called by the current activity in the tab. Those
methods get called by the tab itself. So the tab Onback, onResume ect.
will always be the same for each activity being shown on the tab. Is
there a way so those methods get called by the current activity being
shown, not the tab itself? Also on the back method there is a
problem.

// back
public void back() {
if(history.size()  0) {
history.remove(history.size()-1);
setContentView(history.get(history.size()-1));
}else {
finish();
}
}

it works but none of the activity get finish() or destroyed. So the
heap keeps on getting bigger as more activity are being called.

[android-developers] Re: Mocking static classes like Enviroment

[Kyle Szklenski]

Typically, this isn't done by mocking those classes directly, but
rather by wrapping those classes in interfaces and then mocking said
interfaces. For example, consider the following code (I'm not claiming
this is good code - just a way to use and fix things that you're
trying):


public boolean DeleteTemporaryFiles()
{
boolean result = false;

File rootDir = Environment.getRootDirectory(); // This line sucks
because it can't be mocked
File[] files = rootDir.listFiles();
for(File file : files)
{
if (file.getName() == tmp.txt)
{
result = file.delete();
}
}

return result;
}


So how do you get around the issue of having the
Environment.getRootDirectory() call in there? The easiest way is to
create a simple interface like so:


public interface EnvironmentWrapper
{
File getRootDirectory();
// ... other required functions
}

public boolean DeleteTemporaryFiles(EnvironmentWrapper
environment)
{
boolean result = false;

File rootDir = environment.getRootDirectory(); // Now you depend
on an interface, not the static class. This is called dependency
inversion, because you're pushing the dependency to the caller of the
function, which is above this one.
File[] files = rootDir.listFiles();
for(File file : files)
{
if (file.getName() == tmp.txt)
{
result = file.delete();
}
}

return result;
}


You can take this further, such as with mocking the File calls and
what not, but it may not be necessary in your particular case.

 Hi All,

  I figure that Environment.getxxxState are the functions to check before

  Now, since these are system enforced objects, how do I mock them for
  testing various scenarios without actually using a phone.
  (Another reason to not rely on physical device is that  certain phone e.g.
  Nexus S do not support removal of external storage and I have already made
  that choice :(  )

[android-developers] Licensing with Google street views?

[Kyle Szklenski]

Hi,

I'm relatively new to Android dev and was wondering: In a pay-to-play
Android app, are there any licensing issues with using Google Map's

[android-developers] Android Compatibility Package Next Release

[Kyle Hendricks]

Is there any estimate on when the next Android Compatibility Package release 
will be that fixes fragment animations?

Also, is there a google code page for the compatibility package?

[android-developers] Is there any way to unsubscribe from https://review.source.android.com/?

[Kyle Lee]

I made a mistake of setting different username from my email id. So I
cannot upload my source code to AOSP gerrit review system.
Unfortunately, the gerrit review system does not allow to change
username.

I think the only solution is that I unsubscribe first and register
again with correct settings. But I cannot find a way to unsubscribe
https://review.source.android.com/;.

Please let me know if anybody knows the way to solve my problem.
Best Regards.

[android-developers] WebView Authentication help

[Kyle]

Hello Everyone!


I've created an application which loads a WebView. In order to login,
the website requires basic authentication. When i try to access the
website

If I try to access the website via my application, I get error 401 and
no pop up.

[android-developers] Playing default ringtone with SoundPool or MediaPlayer

[Kyle]

Apologies in advance for asking a question I should be able to figure
out, but I've been banging my head for hours on this and have
obviously got crossed wires in my brain.

How do I get the default ringtone to play? I've tried using SoundPool
(preferred method) and MediaPlayer to play it but I'm getting nowhere.
I've done so many dumb things, I'll just include the last fail. In the
following snippet:

String ringtone = Settings.System.DEFAULT_RINGTONE_URI.getPath();
SoundPool ringPhone = new SoundPool(1, AudioManager.STREAM_RING, 0);
int soundID =
ringPhone.load(Settings.System.DEFAULT_RINGTONE_URI.getPath(), 1);
ringPhone.play(soundID, 0.99f, 0.99f, 1, 0, 1.0f);

loads but plays nothing. When I display
Settings.System.DEFAULT_RINGTONE_URI.getPath(), it's returning /system/
ringtone

Anything that would get me pointed in the right direction would be
greatly appreciated. Thanks,

kyle

[android-developers] How to translate the accelerometer values from the device coordinates to the world coordinates.

[Kyle]

I'm trying to translate the accelerometer values from the device
coordinates to the world coordinates.
It's not clear how to do this.
I guess getRotationMatrix method can do sth about this,and I use the
matrix R the method generated multiply accelerometer values but I did
not get what I expected.

Here is my code:

public void onSensorChanged(SensorEvent event) {

if(event.sensor.getType()==Sensor.TYPE_ACCELEROMETER){
t1.setText(X:+event.values[0]);
t2.setText(Y:+event.values[1]);
t3.setText(Z:+event.values[2]);
e1=event.values.clone();
b=true;

}
if(event.sensor.getType()==Sensor.TYPE_MAGNETIC_FIELD)
{
t8.setText(X:+event.values[0]);
t9.setText(Y:+event.values[1]);
t10.setText(Z:+event.values[2]);
e2=event.values.clone();
b=true;
}
if(event.sensor.getType()==Sensor.TYPE_ORIENTATION){
t11.setText(X:+event.values[0]);
t12.setText(Y:+event.values[1]);
t13.setText(Z:+event.values[2]);

}
if(e1!=nulle2!=nullb==true){
float[] R=new float[9];
float[] I=new float[9];
float[] outR=new float[9];
float[] e3=new float[3];
boolean b=SensorManager.getRotationMatrix(R,I,
e1, e2);
float[] result=new float[3];
result[0]=R[0]*e1[0]+R[1]*e1[1]+R[2]*e1[2];
result[1]=R[3]*e1[0]+R[4]*e1[1]+R[5]*e1[2];
result[2]=R[6]*e1[0]+R[7]*e1[1]+R[8]*e1[2];

t19.setText(X:+e3[0]);
t20.setText(Y:+e3[1]);
t21.setText(Z:+e3[2]);

if(result[0]10.0f|result[1]10.0f){
Log.i(aaa, X:+result[0]+
Y:+result[1]+ Z:+result[2]);
}
b=false;
}
}

The above code seems can do sth expected.When the device stays
statically,result[0] and result[1] approach 0 and result[2] approaches
standard gravity.But when you give the device a acceleration in any
direction,result[0] and result[1] are still 0 while result[2] varies a
lot.
Any help would be appreciated.

[android-developers] intent to play mp4 problems

[Kyle]

Hey,
I've created a WebView which loads a webpage and will play any file
that ends in mp4 on click. The problem is, is that when the
application is loaded on Android 2.2 and I click a mp4 link, it will
open the web browser and immediately close. I can take that same link
and manually enter it into the web browser and the media player will
launch and play the file properly. What I'm wondering is how can I get
my application to properly load the media player and play the video?

4) Compiled successfully
5) Did Run as... so it was running on my G1 device
6) Saw this error in LogCat


How is it that I can compile successfully, but can't find a method at
run time?  (I have 10 years low level programming experience, but am
new to Java)

[android-developers] Geo intent and walking directions (2.0 SDK)

[Kyle]

I'm new to Android development, so in order to learn the API, I've
been working on a sample application that (in theory) would allow
college students to access their course schedule and then locate the
building where that class it being held.  I've got all of the parts
and pieces put together (courses, longitude and latitude of the
buildings, etc) and have successfully launched the geo intent on my
Motorola Droid to pinpoint the specific building I want.

However, the next step is where I'm running into problems, and
wondering if the current 2.0 version of the SDK allows for this...

Using the longitude and latitude of the building (since they aren't
all on a street with a physical address), I want to allow the student
to get walking directions from their point of origin to the
building.

Is there a way, once I have the building pinpointed, to allow the
student to use the menu, select Directions and get the walking
directions from point A to point B?  Right now, if I long press on the
building, it will popup the closest street address and I can get
directions to that, but its not specific to the location I want...

Any help, comments or suggestions would be greatly appreciated.

Kyle

 isAPE'slack of simulating rotation of bodies. I.e. if you simulate
 boxes their x,y positions are calculated but they never rotate. I'm
 pretty sure I haven't overlooked this feature but i'd be surprised if
 it wasn't part of theAPEengine, maybe someone else could confirm

 Anyway,APEis a lot nicer to use than JBox2D and is on a par with
 Phys2D for ease of use. I just wish Phys2D performed well on Android
 then all my problems would be solved!

 With all the attention this topic has brought I hope we can find a
 solution in the not-to-distant future...

   Check out

   http://android-developers.blogspot.com/2009/02/track-memory-allocatio...

   Romain Guy points out in this post that the android garbage
collector cannot optimize small short lived objects.  These are
exactly the sort of objects that could be created in a physics engine
when it needs to generate dynamic collision constraints.  A good
solution in this case is to use a pool of constraint objects because
they are all going to be the same size/object.  The best solution in
my mind would be for the compiler to do escape analysis on the objects
and stack allocate them when it sees that they will never escape the
function.  I have been told that the Java byte code can't reference an
object on the stack.  It's possible that the Dalvik byte code can, I
don't know.

   I don't have a reference for this, but I assume that Dalvik's
inability to optimize small short lived object comes from the fact
that it uses a mark and sweep GC.  On all of my profiling, I see the
GC take at least 100ms to run.  For a game that means you miss from
three to 10 frames of animation and it makes for a pretty noticeable
hick up.  And I don't think it's my application that is causing the
garbage collector to fire.  Unless the OpenGL ES calls do some memory
allocation, which is entirely possible.  I realize that any background
task could move to the run queue and take some time away from my
engine, it just happens to be the garbage collector most of the
time.  :)

   So the result is that the Garbage collector is problematic for me
in two ways.  First, it's not optimized to deal with the sort of small
objects that tend to make for good encapsulations of mathematical
types (like Fixed point number classes or Vector or Matrix classes).
And secondly it takes a long time to run when it does garbage collect,
resulting in dropped frames.

[android-developers] Re: Manipulate Drawable Resource

[Kyle]

Thanks for all of the responses guys. I am referring to the actual
notification icons that show up in the title bar. I know that a
Drawable can be manipulated in many ways and that's what I would like
to do in order to update the icon but the main problem here is that
the Notification object constructor only takes a resource id of a
drawable that was already predefined. Therefore this limits you to
icons that were added to the application before compilation. It would
be nice if I could change the drawable programmatically in my
application and then pass that as the notification icon but it seems
that it's not possible. I was hoping there was a way to do this but I
haven't had much luck finding a solution since I posted this.

[android-developers] Re: Manipulate Drawable Resource

[Kyle]

Hey Kevin,

Thanks for the response. The icon I'm trying to update would be a
placeholder image that I would store in the resources of my
application. I was hoping I would be able to change this within my
program based on certain conditions and have the status bar reflect
the changes when the icon gets updated. (i.e. Say you wanted to keep
an icon of the current temperature in the titlebar and be able to
change that icon in your resources with new text as the temperature
changes.) I know you can customize the view for the window shade but
I'd like to be able to change the actual icon that displays in the
status bar. Notifications only take a drawable resource so I wouldn't
be able to use setImageResource(int resource id) to change that. Would
this be possible at all?

Thanks,
Kyle

 Hi Kyle,

 Where does the icon live that you are trying to update? Is it inside
 of your app, or is it on the Android home screen? From what I can
 gather the SDK does not allow one to update the icon on the home
 screen during runtime (at least that is what I read here on the board
 when attempting to do that), instead you have to use the notification
 layer and post a message to the title bar.

 On the other hand, if you are attempting to change an image/icon
 inside of the app, this is pretty standard. Just grab the current
 ImageButton and call .setImageResource(int resource id). Now, if you
 are getting fancy and just adding a badge or something, it will be
 slightly more complicate, but this should get you up in the right
 direction. Take a look at the draw() methods as well

 Does that help?

\sd.img.  The emulator won't start with this additional argument.
The console says it's launching the emulator, and nothing.  No error.

I have a valid 128M SD Card image I made containing 6 MP3 files.  Any
ideas?

[Kyle R]

It was the program files part.  Thanks.

[android-developers] Problem Centering and Padding Buttons in Layout

[Kyle R]

I cannot figure out how to make 4 buttons, arranged vertically in a
row, centered both vertically and horizontally on the screen.  I don't
get why this is so difficult.  Is there a complete list of button
attributes for the xml file and what they accomplish somewhere?

What I am trying to achieve would look like:

- - - - -

 1
 2
 3
 4

- - - - -

I would like a vertical spacing of about 15 pixels per button.  The
xml code I've got looks like the following, which doesn't work at all.

RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
 android:layout_width=fill_parent
 android:layout_height=fill_parent

 Button
  android:id=@+id/btn1
  android:layout_width=300px
  android:layout_height=50px
  android:textAlign=center
  android:gravity=center_horizontal
  android:padding=15px
  android:text=1/

 Button
  android:id=@+id/btn2
  android:layout_width=300px
  android:layout_height=50px
  android:textAlign=center
  android:gravity=center_horizontal
  android:padding=15px
  android:layout_below=@id/btn1
  android:text=2/

Button
 android:id=@+id/btn3
  android:layout_width=300px
  android:layout_height=50px
  android:textAlign=center
  android:gravity=center_horizontal
  android:padding=15px
  android:layout_below=@id/btn2
  android:text=3/

 Button
  android:id=@+id/btn4
  android:layout_width=300px
  android:layout_height=50px
  android:textAlign=center
  android:gravity=center_horizontal
  android:padding=15px
  android:layout_below=@id/btn3
  android:text=3/

/RelativeLayout

                           android:layout_width=300px
                           android:layout_height=50px
                           android:textAlign=center
                           android:padding=15px
                           android:text=2/
                 Button
                           android:id=@+id/btn3
                           android:layout_width=300px
                           android:layout_height=50px
                           android:textAlign=center
                           android:padding=15px
                           android:text=3/
                 Button
                           android:id=@+id/btn4
                           android:layout_width=300px
                           android:layout_height=50px
                           android:textAlign=center
                           android:padding=15px
                           android:text=4/
         /LinearLayout
 /LinearLayout

 I'll admit I'm not 100% certain why both gravity:center attributes are
 needed -- I'd've expected the one on the outer-most LinearLayout would
 have done the trick. But, this seems to give the visual effect you're
 looking for, if I understood you correctly.

[android-developers] Re: Problem Centering and Padding Buttons in Layout

[Kyle R]

Is there a way to space the last button so its placed further from the
top 3?  It's not the padding option.  It would therefore look like:

- - - - -


 1
 2
 3

 4


- - - - -

Thanks again for your help.
