If your app is top rated and you have a few hundred ratings at least,
this should be a good way to go.

[android-developers] HTTP request to Android Market being blocked? (403 response)

[Jason]

Hi folks,

I'm building a system in which I'm wanting to verify the ownership of
a given Android app to a given user.  (eg. they enter the package name
of their app, and I verify that they own it).  I am currently using
Google App Engine for this, but it seems this is being blocked by the
Android Market.

When I try to access the android market page for any given app I get a
403 coming back from the Android Market. In fact any simple GET on a
market HTTP url responds with a 403 when running in GAE, but works
fine when running locally.

Does anyone know if the Android Market is blocking HTTP requests
coming from Google App Engine?

Thanks.

It's reasonable to expect that they will attempt to shake down everyone 
who sells an Android app. It's not reasonable to expect that they will 
actually sue everyone they contact. Nobody has the resources to do that. 
I still think this is just one guy in a dark room writing threatening 
letters hoping to scare people into sending him money. Not much 
different from the Nigerian prince scam, only legal.


The more of these letters we see, the less likely it is that any of them 
can be taken seriously.


My opinion of course.

We currently evaluating our opertunities but as a legal fight with a
patent bully and paying a patent license for the next years is not a
big option for us, we currently considering pulling all our demo
versions from the U.S. market and only offer payed versions.

I'm close to releasing a new iPhone/Android local multiplayer game and I'm
looking into monetization issues. My ad revenue is still dismal this year,
even though impressions and clicks are fairly robust. And the format of the
game is such that I want to encourage new users to easily try the game for
free, so I was thinking of using a freemium model where the app is free to
download, then locks after a certain amount of gameplay and prompts the user
to unlock the full version using in-app purchases.

I'd be interested to hear any experiences of any developers who might
currently be using this approach.

 From a marketing/sales perspective, how well does this model work? I know
in-app purchases for virtual goods is extremely lucrative if done well, but
I haven't heard any experiences of the unlock-full-version model on the
Android Market.

 From a technical perspective, how easy is it for users to exploit such a
model, e.g. uninstalling and reinstalling the app or wiping local data
associated with the app in order to circumvent the limitations of the free
version? Are there best practices to avoid this?

 From a legal perspective, should developers (especially indie ones like me)
be concerned about the current patent trolling and lawsuits by companies
like Lodsys? Google still hasn't publicly commented on patent trolls
targeting Android developers, have they?

The guy is still writing letters so it stands to reason some people are

Hi makjaveli,

i recieved a Lodsys letter 2 Days ago. Same Problem here. I have a 
button in my app linked to the Android Market. It's simply a button 
with a underlaying http Link pointing to the payed app URL. I can't 
think of a szenario where this can be proteced by a patent, because it 
a common/trivial link mechanisam found everywhere in the net , 
websites, apps, mobile apps, whatsoever.


Because I'm only a hobby programmer while my app sold like 250 times ( 
maybe 100 to US) I'm not sure what to do. I read their article on 
"what are we charging"
http://www.lodsys.com/1/post/2011/05/q-what-are-you-charging.html and 
thought it would be a solution to ask for licening an pay them ~ 5$ 
for the past usage.


Has anyone solved his Lodsys claim fast and easy ?

[android-developers] DashboardLayout (iosched 2011) behaves weirdly

[Alexis Robert]

Hi,

I have a little problem with DashboardLayout (the one on iosched 2011
mercurial repository) and as I really don't know what's wrong. I know
I'm wrong somewhere, as this layout works for the I/O app, and I've
tried to copy the situation of the I/O app everywhere I can, but
nothing worked.

When I'm in portrait, everything is fine :
http://img405.imageshack.us/img405/4851/device20110827093725.png

But when I'm in landscape, DashboardLayout behaves weirdly
:http://img231.imageshack.us/img231/3061/dashboardlandscape.png

For the source code,

-- home.xml --


http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical">










-- style.xml (stripped down to only useful parts) --






true

@style/ActionBarButton
@style/ActionBarSeparator
@style/ActionBarText



wrap_content
wrap_content
bold




By the way, if I uncomment the @null line, it gets even worse in
portrait : http://img32.imageshack.us/img32/3713/dashboardportraitnobg.png

Thanks a lot !!

[android-developers] Re: reading choices from spinners

[FBondarenko]

That's a java thing:

to compare Strings use something like if (strResult.equals("Four")),
as (strResult == "Four") checks if the operands are the same object
and not if they have the same content.

[android-developers] Re: how can i update my application without adding more devices?

[李白|字一日]

i would like to ask google why,

previously because of the signature expiration,
i had to republish my application with new package name.

this time again because my updates didn't change supporting devices?
my new updates cann't be published? why?

"
错误：6 版的 APK 与其他更高版本的 APK 所支持的设备完全相同。系统不会推出这样的 APK，请取消激活该 APK。
"
which means :
version 6 and other higher version apk support totally the same devices.
system will not publish this APK, please cancel activating this APK.


is there a way to solve this problem?

[charlie babitt]

Hallo!

Looking on the google+ app on the dashboard, I have seen that they
display my profile image and draw a blue circle arround it. What is
the easiest way to achieve something like this? I want to create an
ImageView which contains an image (I'm loading it from the SD Card)
and drawing a rectangle as a frame around it. Where should I start
looking?

Thanks
charlie

Re: [android-developers] Re: Just received Lodsys letter...

[Andy]

Question would be as "super small developer" whats the easiest Exit 
Strategy.

A Patent Lawer in the US easily costs serveral hundert $/hour. Their 
strategy might be that this effort is too big for most of us. (Especially 
from Europe / laguage barrier) So after reading 
http://www.lodsys.com/1/post/2011/05/q-what-are-you-charging.html i was 
thinking if the easiest way to sleep better ist, ask them what you have to 
paid for the past and future use.

In case you removed the Button it would be the question how to the know how 
many apps you have sold in the US. If you sold you app like 500 times for 2 
$ this might be a very small amount of money you have to spend. The Question 
remains it this is legit because their claim that even a link to the Market 
violates one of their patents is kind of odd, because than you can claim 
that exact case for every website linking to a Commercial Item like Amazon 
links oder whatsover. Same Mechanism. The Button in you game is only a HTTP 
Link to a Android Market website. No Strings attached. 

Next question qould be hwo to contact them, and how fast do they respond. 

Anybody experienced a solution that was heading for a licening ?

[groob]

That's the solution we used in another title. I don't like it at all,
but nothing else can be done, as one can see.

Thank you.

[android-developers] Re: activity transition animations

[Jona]

Create your own custom theme and override the activity animations.
See the theme.xml file located under the android sdk.

[android-developers] Re: In-App Billing forces screen orientation change

[groob]

Thank you for your interest, TreKing.

The strange thing is the display is of course rotated, but alsoscaled
down in height and untouched in width, so it looks like GL scaling has
been applied.
Nevertheless it might look like a bug or at least an unhandled
behaviour, so I need to get rid of it somehow.

The bug substance and the reason I ask a question here is that my
application is changing its orientation although I think I've done
everything what's needed to protect me against it.
To me IAB implementation is buggy and ignores this setup, not allowing
as well to handle rotations programmatically.

Will try with reporting the issue, but just cannot wait till anyone
address it. Zsolt's solution is not elegant at all, but the only quick
one I can imagine.

Thanks!

[android-developers] Crash on SQLiteOpenHelper::getReadableDatabase when I'm trying to copy new db from raw resources

[pawpaw17]

Hi Guys,

I ship a pre-created database as a raw resource and copy it into my
app's
database folder at startup. When I ship updates I overwrite the old db
with
my new db, which sometimes includes new stuff.

I can't reproduce this with any of my devices, but some of my app's
users
get a crash when my app calls this.getReadableDatabase() in my
override for
createDataBase:

android.database.sqlite.SQLiteException:
Can't upgrade read-only database from version 62 to 1: /data/data/
com.myapp.myapp/databases/ls.db
at
android.database.sqlite.SQLiteOpenHelper.getReadableDatabase(SQLiteOpenHelper.java:
236)
at com.myapp.myapp.DataBaseHelper.createDataBase(DataBaseHelper.java:
75)
at com.myapp.myapp.myapp.MyApp$11.run(MyApp.java:675)
at java.lang.Thread.run(Thread.java:1020)

public void createDataBase() throws IOException{
boolean dbExist = checkDataBase();
if(dbExist){
//do nothing - database already exists
}else{

// delete the old database
this.getReadableDatabase();   <<< Exception is thrown HERE

try {
  copyDataBase();

} catch (IOException e) {
throw new Error("Error copying database");
}
}

}

I copy the database as follows:

private void copyDataBase() throws IOException{

//Open your local db as the input stream
InputStream myInput = null;

// Path to the just created empty db
String outFileName = DB_PATH + DB_NAME;

//Open the empty db as the output stream
OutputStream myOutput = new FileOutputStream(outFileName);


myInput = myContext.getResources().openRawResource(R.raw.ls_db);
//transfer bytes from the inputfile to the outputfile
byte[] buffer = new byte[1024];
int length;
while ((length = myInput.read(buffer))>0){
myOutput.write(buffer, 0, length);
}
myInput.close();



//Close the streams
myOutput.flush();
myOutput.close();
myInput.close();

openDataBase();
myDataBase.setVersion(packageVers);

// Copy stored data to new database
...

close();
}



Is the call to:

// delete the old database
this.getReadableDatabase();

problematic? What I really want to do is

chmod 777 myolddb
rm -f myolddb

if this were plain old Unix. What situations can lead to Android
treating this
as a read-only entity that can't be overwritten? This database is
originally created
by my app, and I only overwrite it on app updates.

Thanks!!

Re: [android-developers] Re: Just received Lodsys letter...

[Andy]

I'm only accused for 7,222,078 (the in app billing)

beside my app has no in-app purchase or upgrade. It's simply a http link to 
the android market.I think they are sure that their patent covers the 
process behind this?!?!. But if so, this would ment, that even  
web-Applications are not allowed to link to a amazon store or something 
similar. This patent is so common sense / so widely interpretable that I 
think this will not last "that long".

[android-developers] Advice on getting data from one activity to another

[erik wagner]

Hi, I guess this is more of a design with more than a little 'how do
i' mixed in question.  I have two activities (thus far), a main page
and an options page.  On the options page I set an option that I need
to 'see' on the main page (as well as on subsequent other activites).
What is the 'best' way to do this?  Global variables are a no-no and a
bit of a pain to do as I understand it.  How can I do this?  Perhaps
just point me in the direction of a dev article on the subject though
I couldn't find anything on point.  At least at that point I can then
move on to more detailed how-to questions.  Thanks again for all the
help on my various newbie questions.

[android-developers] SSH to device

[kypriakos]

Hi all,

I have the SSHDroid running on the device and I can ping it. But ssh-
ing to it asks for a root
passwd and I am assuming that means the phone needs to be rooted, or a
root login added
to it? Not sure. Since the ssh server is running on a particular port
and I get a login prompt
back I am assuming that there should be a login of some sort i can use
to access the shell?
Any ideas?

Thanks

Support for SSHDroid is presumably provided by the SSHDroid authors,

Use SharedPreferences and an OnSharedPreferenceChangeListener.

[android-developers] Re: SSH to device

[kypriakos]

Agreed. A more general question:

What does the "adb connect" do exactly? Not much info on the adb page
about it.
If I run it it says that it's connected to the device but it shows it
as offline.
Is this supposed to be used in combination with any 3rd party app or I
should
be able to issue commands to the device remotely?

I have been using the USB connection and issue adb shell on the device
I can use
'su' to be able to let's say kill apps that are not responding. I want
to be
able to do that without the USB connection and via TCP.

I can tell you that I've used QuickSSHd
(http://teslacoilsw.com/quicksshd). You supply the SSH password in the
QuickSSHd activity and use that to log in with a semi-arbitrary user
name, or you can use SSH shared keys. I can't speak to the `su` stuff,
but QuickSSHd does appear to support root.

Here is a sample project showing using SharedPreferences and a
PreferenceActivity:

https://github.com/commonsguy/cw-android/tree/master/Prefs/Simple

Whether you even need the OnSharedPreferenceChangeListener is
debatable, depending on your application flow. I re-read the
SharedPreferences in onResume(), for example, in the sample project
above.

If you are going to create an "options" screen, please please please
consider using a PreferenceActivity.

[android-developers] Android SDK 2.3.3, another bug, can't download APK.

[sblantipodi]

Hi,
can you tell me why I can't download .apk file from the 2.3.3sdk
browser?

I can do it with all other SDK version but not with 2.3.3.

Thanks.

[android-developers] Terminating apps

[kypriakos]

Hi again,

I issue a finish() on a single process app, it exits to the home
screen of the
phone but a ps shows that the process is still running. Is this the
proper
way to terminate an app? I thought so.

Thanks

Android will terminate the process eventually. Android keeps the
process running initially, in case the user happens to pop right back
into it, so they can get into the app more quickly and with less
battery use. Once Android starts needing RAM for other apps, though,
your unused process will be terminated.

finish() is the proper way to exit an activity. You do not "terminate
an app" on Android any more than you "terminate a Web app".

[android-developers] Question around Bitmap loading

[blew]

Hello fellow developers,

This is again, about the famous "external allocation too large for
this process" Out of Memory exception when loading Bitmaps into your
memory.
The problem revolves around the following error message:

1502400-byte external allocation too large for this process.
Out of memory: Heap Size=5123KB, Allocated=2481KB, Bitmap Size=11183KB
VM won't let us allocate 1502400 bytes

I've been doing some simple tests and I just can't seem to figure out
what the "Bitmap Size" means.

The bit of code which generates the above error is as follow:

I call the following line (nothing else, this is my main call):

Bitmap bitmap =
loadBitmap(resources.getDrawable(R.drawable.map_image),
Config.RGB_565);
Bitmap bitmap1 =
loadBitmap(resources.getDrawable(R.drawable.map_image),
Config.RGB_565);
Bitmap bitmap2 =
loadBitmap(resources.getDrawable(R.drawable.map_image),
Config.RGB_565);
[...]
Bitmap bitmap9 =
loadBitmap(resources.getDrawable(R.drawable.map_image),
Config.RGB_565);

about 10 times

The map_image has the following dimensions: 1565x480
So it's using up 1502.4kb of memory: 1565*480*2/1000   (*2 => RGB_565)

The loadBitmap function used in the above few lines will call the
following function:

static public Bitmap loadBitmap(Drawable drawable, Config
bitmapConfig) {
int width = drawable.getIntrinsicWidth();
int height = drawable.getIntrinsicHeight();
long sizeStart;
long size;

Bitmap bitmap;

sizeStart = Debug.getNativeHeapAllocatedSize();
bitmap = Bitmap.createBitmap(width, height, bitmapConfig);
size = Debug.getNativeHeapAllocatedSize() - sizeStart;
System.out.println("Created : " + bitmapConfig.toString() + " : 
" +
size/1000 + " Kb, " + bitmap.getWidth() + "x" + bitmap.getHeight());

Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, width, height);
drawable.draw(canvas);
return bitmap;
}


Now when I run the code, I will get about 5 calls to the loadBitmap:
Created : RGB_565 : 1503 Kb, 1565x480
Created : RGB_565 : 1503 Kb, 1565x480
Created : RGB_565 : 1503 Kb, 1565x480
Created : RGB_565 : 1503 Kb, 1565x480
Created : RGB_565 : 1503 Kb, 1565x480
Before getting the dreaded:
1502400-byte external allocation too large for this process.
Out of memory: Heap Size=5123KB, Allocated=2481KB, Bitmap Size=11183KB
VM won't let us allocate 1502400 bytes

Now I understand that 1502400 bytes is the memory needed to load a new
bitmap.
I'm guessing that the 5123+2481KB represent (approximately) the 5
previously loaded bitmaps (7604/5=1520.8)

But what in god's name is that Bitmap Size value? what is using up
those 11 megs?

My subsequent question is: In theory I should be able to load 10 times
that 1.5 mb bitmap in my memory (before I reach the 16mb limit) why am
getting an exception after the fifth bitmap?

Thank you very much for any reply or leads you might be able to give
me,

Regards,

[android-developers] Accelerometer vs Gravity Sensor in game code?

[Jim Graham]

When writing game code, what (if anything) is the difference between
the accelerometer, G-Sensor, and Gravity Sensor?  I'd assumed that
they were all different names for the same thing, until I pulled
up specs on my Motorola Bravo (MB520), and found a device id for
the accelerometer, an "Unsupported" for the Gravity Sensor, and
no mention of a G-Sensor (which I'm guessing is a Gravity Sensor).

Now I'm not so sure.  So, when writing game code, is there any real
difference?  Are they basically the same thing?  Or are they
completely different sensors?

In trying to find the answer myself, I found a lot of discussios
that went like this:

   An accelerometer is [this], and a G-sensor is [that].
   An accelerometer is [that], and a G-sensor is [this].
   An accelerometer is [that], and a G-sensor is [this].
   An accelerometer and a G-sensor are the same thing.
   An accelerometer is [that], and a G-sensor is [this].
   An accelerometer is [this], and a G-sensor is [that].
   An accelerometer is [that], and a G-sensor is [this].
   An accelerometer and a G-sensor are the same thing.
   An accelerometer is [this], and a G-sensor is [that].

and so on, ad nauseum

Is there an authoritative answer out there?

[android-developers] WebView with Admob Error

[OneaDayJ]

Hey guys,

Okay, so I am having a heck of a time here doing this app.  I am
trying to create an app that has the webview up top and admob ads at
the bottom.  I got the webView aspect to work then when I tried to ad
the admob I began getting errors.  I first added the manifest and it
worked fine, but then when I tried to ad the admob xml to the main.xml
file I get a force close error before it opens.

I have many apps that the admob does fine, so I am pretty sure it is
just the combination of the 2

You would use it to connect to a device which has an adbd listening on 
something other than the USB, for example listening on TCP so that you can 
have ADB over wireless (or even wired ethernet on some non-handheld 
platforms).

For something you would leave running, ssh could be preferable as ADB has no 
security.

In either case though, excepting system-level debugging its probably 
preferable to have the daemon started/stopped by an android app control 
panel, with status bar notification while it is on, so that you only have it 
on when you expect to be using it.

[android-developers] Re: SSH to device

[kypriakos]

Yes the security aspect is important so I agree with the suggestion.
However, I think I did try something along these lines a while back
but it didn't work. Is this the right approach? With the phone on USB:

setprop service.adb.tcp.port 
stop adbd
start adbd

Rebooting the phone removed the property.

Thanks

[android-developers] How does Android EditText store the content internally

[KK]

Hi,

  I have an android EditText which holds a password. I have to
retrieve this in one of my modules and pass it to another. I am
calling EditText.getEditableText and encrypting its content. But I
want to know if android creates any immutable objects internally for
the EdiText Content(like String), in which case there might still be a
way for a hacker to get the password out?

Thanks

Yes. How long will depend on what's all going on. I would expect it to
be gone within an hour or so, given various services that will wake up
periodically to do a bit of polling. Quite possibly it will be gone
much more quickly.

> Is finish() synchronous and it occurs immediately?

No, and no.

finish() will happen very quickly, but it is not synchronous (i.e., a
blocking call) and therefore cannot be construed strictly as
"immediately".

If by "it", you mean "the process", please do not do this. Please let
Android terminate it when it is ready to. Whatever problem you are
trying to solve can be solved better some other way.

> On a different note - how far back do your books go? Did you cover
> 1.6 and 2.1?

Yes. 1.5, even. Mostly, I cover "Android" and try to point out when
various new-ish features were added to the OS.

Re: [android-developers] How does Android EditText store the content internally

[Kristopher Micinski]

You're not doing any IPC?  Perhaps I didn't get that, but because
you've got sandboxing, if you're keeping the password entirely in your
program memory you should be fine with it, modulo possible security
flaws in the vm, etc...

If you're leaking the passwords out across an IPC barrier, you might
want to be more careful.

[android-developers] Using multiple fragments in each screen in ViewPager

[winnie]

I have been trying the ViewPager from recently supported android
compatibility v4 package.

In my app, I have multiple screens which I would like to swipe across
just like what ViewPager does. But in my app, I have multiple
fragments in EACH single screen. In the ViewPager, the
FragmentPagerAdapter seems to be for the purpose of using multiple
screens, each with single fragment.

I am wondering if there is anyway I could use the current support
package for my current requirement? Or I need to go back to the same
android launcher src to reference and design my custom control.

Re: [android-developers] Accelerometer vs Gravity Sensor in game code?

[Christopher Van Kirk]

They could be referring to a gyroscope sensor. The new Samsung devices 
have those now in addition to the accelerometer.


On 8/28/2011 12:28 AM, Jim Graham wrote:

When writing game code, what (if anything) is the difference between
the accelerometer, G-Sensor, and Gravity Sensor?  I'd assumed that
they were all different names for the same thing, until I pulled
up specs on my Motorola Bravo (MB520), and found a device id for
the accelerometer, an "Unsupported" for the Gravity Sensor, and
no mention of a G-Sensor (which I'm guessing is a Gravity Sensor).

Now I'm not so sure.  So, when writing game code, is there any real
difference?  Are they basically the same thing?  Or are they
completely different sensors?

In trying to find the answer myself, I found a lot of discussios
that went like this:

An accelerometer is [this], and a G-sensor is [that].
An accelerometer is [that], and a G-sensor is [this].
An accelerometer is [that], and a G-sensor is [this].
An accelerometer and a G-sensor are the same thing.
An accelerometer is [that], and a G-sensor is [this].
An accelerometer is [this], and a G-sensor is [that].
An accelerometer is [that], and a G-sensor is [this].
An accelerometer and a G-sensor are the same thing.
An accelerometer is [this], and a G-sensor is [that].

and so on, ad nauseum

Is there an authoritative answer out there?

I'd assume that he means that he's sleeping in the main thread and
it's causing ANRs, or just sluggish performance.  If you want to
download data, do it in a separate thread, look at AsyncTask.  If you
look at AsyncTask, you should find what you need, you can google
around for examples.  You can also use a service to do your
downloading for you, if you want to coordinate between different
pieces of the app.  (Note however, that you still have to use a
separate thread, as a service in and of itself is not a separate
thread.)

[android-developers] Implementing onShowCustomView on Android 3.1 throws in HTML5VideoFullScreen

[novemberox]

Hi,

I'm trying to play video in html on fullscreen. When I click on
fullscreen button in video method onShowCustomView is fired. Here is
my implementation:

public void onShowCustomView(View view, CustomViewCallback callback)
{
super.onShowCustomView(view, callback);
if (view instanceof FrameLayout) {
customComponenet.addView(view, new 
FrameLayout.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.FILL_PARENT,
Gravity.CENTER));
customComponenet.setVisibility(View.VISIBLE);
}
}
Where customComponenet is FrameLayout placed on top of my current
layout. Wideo is playing good, it's visibile and everything seams to
be ok but it throws:

What am I doing wrong?

My WebView settings:
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setPluginState(PluginState.ON);
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setDatabasePath("/data/data/" +
App.class.getPackage().getName() + "/databases");
webView.getSettings().setSupportZoom(false);

I'm testing on Galaxy Tab 10.1, on default browser this is working
just fine. I can switch to fullscreen. Moreover in my app when I play
video embeded I can hear only sound and see status bar below area
where video should be, while on browser I can see video both embeded
in WebView and on fullscreen.

Good point, good point, but I was just speaking about the "Service"
class.  (However, you might look into IntentService as well.)

I would start with ImageView, see what you can do with that, and read the
docs on the various layout, and what you can do with those. FrameLayout in
particular may be of interest to you.

Because the rest of your app is using memory as well.

Good! That's a good approach. I like to study the OS but through its
