[android-developers] In-app purchase signature verification with PHP openssl
In an attempt to follow some of the security guidelines for in-app
purchase here:
http://developer.android.com/guide/market/billing/billing_best_practices.html
I am trying to do signature validation on a server instead of in the
app iteself. I would ideally like to use the php openssl libraries and
it looks like code such as the following should work:
?php
// $data and $signature are assumed to contain the data and the
signature
// fetch public key from certificate and ready it
$fp = fopen(/src/openssl-0.9.6/demos/sign/cert.pem, r);
$cert = fread($fp, 8192);
fclose($fp);
$pubkeyid = openssl_get_publickey($cert);
// state whether signature is okay or not
$ok = openssl_verify($data, $signature, $pubkeyid);
if ($ok == 1) {
echo good;
} elseif ($ok == 0) {
echo bad;
} else {
echo ugly, error checking signature;
}
// free the key from memory
openssl_free_key($pubkeyid);
?
I replace signature with the base64 decoded signature string in the
app purchase bundle and the use the data from the same bundle. The
public key needs to be in PEM format and I added the BEGIN and END
tokens and some line breaks.
My problem is that I can not get this PHP code to successfully verify
the data/signature and I do not know what needs to change to get it to
work correctly.
If I use openssl, create a private and public key, create a signature
for the same data using sha1 and run it through the above php code, it
works fine and validate successfully.
Here is how I use OpenSSL:
openssl genrsa -out private.pem
openssl rsa -in private.pem -pubout -out public.pem
then i use the private.pem and some php code to generate a signature:
...
openssl_sign($data, $signature, $pkeyid);
...
Does anyone have any working sample php code with server side
validation of in-app signatures?
I could just run the equivalent java code that is in the sample
application, and that seems to work ok, but I would like to use php
directly if possible.
Thanks,
Nate

Hey Joe, As I understand it, *both *MAY be available. The PN544 controller has an embedded smartcard, so there's that, and it also supports SWP (for compliant SIMs). Which is used depends on the application, applications on the smartcard would be 'linked to your phone', while applications on the sim would be 'linked to your number'.

[android-developers] Re: The Blinking Activity of Death
The problem is, this happens randomly, on several unrelated Activities and there are no problems 99% of the time. By the way I meant onCreate (not onStart) in my previous mail.

We know it's a bad thing to do and we're in the process of fixing this. We do not see lots of ANRs though. But I was wondering if taking too long in onCreate could somehow lead to this behavior?

but can anyone tell me how can i apply drm rights to my songs. Google for these : WMDRM or AAC DRM But I'm not sure WMDRM is readable by Android. Just so you know : If your content is this valuable that you want to encrypt it with DRM(wich is flawed anyway) then be warned that this content will be offered for free everywhere on the Internet in less than two monthes(days it it is really great content). The only reason I would go to all the trouble of finding a way to add DRM to files is to seal a deal($$) with less tech savvy people that would think that the content they produce is safe in my app(even thought it is not really). Say these mp3's are the best mp3's on the planet and I'm a low tech hacker : I'd plug a jack in my phone and to my computer, play the file on the phone and record it in the computer and tadah, I have ripped your MP3 and your $12 000 DRM licence + 10 days work for the implementation are just a pure loss of money and time.

That's what I do - bring up Project Properties every once in a while, and set Android build target to 1.6 (or whatever may be needed). But that doesn't really work, at least in my case. I conditionally use features from API Levels 4, all the way to 11. Setting the compiler to build against Level 4 would cause compiler errors, which it should.

Re: [android-developers] Re: Rounding Numbers
Zsolt, I hear what you are saying and generally agree, however we have been using calculations 'plagued by rounding errors' for centuries and our bridges are not collapsing. Such is a nature of a calculator, even scientific one. there is a reason, why Math Java API or even Apache Commons Maths use doubles everywhere: http://download.oracle.com/javase/6/docs/api/java/lang/Math.html http://commons.apache.org/math/ The reason being speed and simplicity. Now looking at BigDecimal API (http://download.oracle.com/javase/6/docs/api/java/math/BigDecimal.html), how would you calculate say cube root of said BigDecimal or maybe any trigonometrical function?

Hi JMC, I agree with you. I hope that Android will support the SE on the SIM. So the user can have all the personal infos(billing, ticketing, etc) on the SIM and when he changes the phone he can take the infos to the new phone or when he loses the phone the operator can block the SIM.

The PN544 controller has an embedded smartcard, so there's that, and it also supports SWP (for compliant SIMs). Which is used depends on the application, applications on the smartcard would be 'linked to your phone', while applications on the sim would be 'linked to your number'. That's the idea as I interpret it, feel free to correct. Support on Android will be implemented in due time as Nick mentioned.

Kostya most likely got different case as he checks if he is not (unintentionally) using something that does not exists in lower API. Yes. You can't directly call a class or method that doesn't exist in the SDK you're building with. Doing this requires the use of Java reflection. So there are two ways really: - Build against the highest SDK version, create wrapper classes for higher / lower API versions, switch them at runtime depending on the actual device API level. - Build against the lowest SDK version, use Java reflection to access higher API methods. However, if you're going to use any higher features in the manifest, you have to build with that higher version. There is no reflection for the manifest. Yes, you shall pay more attention to testing if your app does what you say it do, because there's higher risk of facing bug or problems caused by this conditional code. +100500 to testing :) Compiling against the lower version is a good quick sanity check. -- Kostya Vasilyev -- http://kmansoft.wordpress.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Display indeterminate progressbar in Status bar on Android
Hello, I am trying to display an animated graphic identical to the indeterminate progress bar (not the horizontal one, but the circular one) in the status bar while my on-going notification is alive. I tried to find the resource ID corresponding to the indeterminate progress bar, but found that it is animated via code. I tried setting the icon ID in my Notification instance to an animated GIF, but only the first frame of the GIF is displayed in the Status bar. If I set the icon ID to android.R.drawable.progress_indeterminate_horizontal, the graphic animates perfectly. So, my question is- how is the animation achieved in this case? Through iconLevel? How can I set an animated icon without requiring to animate it periodically myself? Any pointers will be really appreciated.

[android-developers] Returning to previous screen after receiver activity.
Hello ... I have a app that has a activity that can be started from the start menu and a activity that is strated by a intent receiver. Now on boot , if the receiver is called , the activity is started...after backing out of this activity user returns to previous screen (could be home or whatever user was doing) .. this is how it should be. But if i start the other activity from the main launcher, and press the home button to go back to the home screen..the problem begins. Now if the receiver is called , and user backs out of receiver activity..the main (still running in background) activity is shown... This is not how i want it..because it causes users after dismissing a calendar event (the purpose of my app) to return to eg the settings from the main app.. If i call finish() in onpause , it works ok...but that is not the way it should work. Any clues? Hope the problem is clear , since english isn't my first language i found it hard to explain the problem :-) Thanks.. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] GLSurfaceView + Android 2.3.x = EGL_BAD_ALLOC
Hi,
i got some reports from users of our framework that opening/closing an
OpenGL ES based app would force close with an EGL_BAD_ALLOC after
~20-30 open/close cycles on an Android 2.3 device. To eliminate any
problems related to our framework i wrote the simplest GLSurfaceView
based app i could come up with:
package com.badlogic.egl;
import javax.microedition.khronos.egl.EGLConfig;
import javax.microedition.khronos.opengles.GL10;
import android.app.Activity;
import android.opengl.GLSurfaceView;
import android.opengl.GLSurfaceView.Renderer;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
public class EglBadAlloc extends Activity {
GLSurfaceView view;
@Override public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
view = new GLSurfaceView(this);
view.setRenderer(new Renderer() {
@Override public void onDrawFrame (GL10 gl) {
gl.glClearColor(1, 0, 0, 1);
gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
}
@Override public void onSurfaceChanged (GL10 gl, int
width, int
height) {
}
@Override public void onSurfaceCreated (GL10 gl,
EGLConfig config)
{
}
});
setContentView(view);
}
@Override public void onPause () {
super.onPause();
view.onPause();
}
@Override public void onResume() {
super.onResume();
view.onResume();
}
}
Running this on a Nexus One/Samsung Galaxy S with stock 2.3.3 will
eventually result in a force close with the following interesting
stack trace:

To reproduce the issue just open and close (via the backbutton) the
app above around ~20 times in succession. The app is cached on 2.3 it
seems, The cache memory is growing and eventually the EGL error will
appear, force closing the app.
I looked at the sources of GLSurfaceView for 2.2 and 2.3 (latest AOSP
release tag in both cases) and there seem to be some changes in the
way EGL context destruction is handled. It seems that one can
explicitely request a the context destruction now. Sadly my brain
couldn't untangle the logic behind all that yet (and i'm afraid i lack
the time to go further down that rabbit hole).
So, before i log a bug on b.android.com, does anyone see a problem
with my above Activity code? Is there any solution that might not
require waiting for the next Android release and it's deployment?

[android-developers] Re: 3d engine advices
The overhead introduced by Interfaceing GL10/GL11 and GL20 is neglible i'd say. Sadly, there's no work around for that, i'd have prefered a static method solution if at all possible, but so is live. In real- world scenarios that overhead does not have an noticeable impact on your performance, tuning other things like texture filters/sizes will have a 100x bigger impact on the performance of your game. We are currently in the process of rewritting the 3D utility classes of libgdx, including better model format support among other things. See the blog at http://www.badlogicgames.com for more info (as well as the forums :)). Btw, Peter, Gamine looks very interesting as well! You should consider using a different license though, LGPL and Android don't mix well due to the dex format (users can't exchange the Gamine impl due to dex, which is a requirement of the LGPL if you don't provide the source of your complete app).

[android-developers] Eclipse/ADT not rebuilding correctly
I started noticing this problem about two weeks ago, but it's hard to nail down. I would change something in my code, wait for eclipse to finish building, deploy to my emulator or device, and proceed to step on the new code. I'd see no change and would then check my logs to see what happened: whatever change I just made wasn't in the code on my emu/device. I have checked the console output, and it uploaded a new APK. I would try and redeploy from Eclipse, and it says the APK is already installed, no need to reinstall. The only way I have found to fix this issue is to either close eclipse entirely, or clean the project. Doing either of these things completely defeats the purpose of having a build automatically option, and in general I choose to restart eclipse because many times ADT will trip over itself while cleaning - see one of the many posts about not finding the gen folder - ugh... Has anyone else had this problem with ADT? Does anyone from either the community or the ADT team have an explanation/workaround/fix? This sometimes happens around 20 times a day, which is really quite annoying. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] when activity loads first time onscroll method is called?
hi,
I am displaying listview within activity.and for list view i am
loading data from server on scroll event.
like
public void onScroll(AbsListView view, int firstVisible, int
visibleCount,
int totalCount) {
boolean loadMore = /* maybe add a padding */
firstVisible + visibleCount = totalCount;
if (loadMore) {
if (loadMore) {
if (!isAlive) {
isAlive = true;
new BackgroundProcess().execute();
}
}
}
}
my problem is that when the activity loads first time onScroll method
is called by default.
is there anyway to prevent this.

[android-developers] EditText Issue
Hello all. I am running a DROID with Android 2.2.2 on it. I have a
project I've been working on for a while, a chat client. However,
this one is a specific type. I need to make it so the user can not
move the cursor to any part of the text, so it has to stay at the end
of the text they are typing. I have the code to set to, when the
EditText is clicked, move the selection to the end of the box.
However, it's not working. Here is my code:
// Set a listener for editText
myEditText.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
myEditText.setSelection(myEditText.length());
myEditText.extendSelection(0);
myEditText.setSelection(0);
}
});
This is the code I have found (and mall variations from it) everywhere
that someone has said to use it. However, it's not working on my
DROID.
** I also need to make it so that they user cannot use the arrow keys
on a keyboard as well to change the position of the cursor.
Please help! Thanks for your time!

[android-developers] Re: OutOfMemoryError- while to download big data and storing in db4o
My first answer would be: use less memory by chopping up the large text file in chunks. My second answer is this: Apart from setting null values to your (temporary) objects, try to call System.gc() as well. It *may* improve your situation somewhat, since Android's (DalvikVM's) garbage collector is non-compacting. -- You received this message because you are subscribed to the Google Groups Android Developers group.

It may have to do with the initialization of the database during the

base baseDatos = new base(this,programacion,null,1);
SQLiteDatabase db = baseDatos.getWritableDatabase();
These fields are assigned during the construction of your TabActivity.
Move these two lines into your onCreate, where your TabActivity should be
initialized.
...
base baseDatos;
SQLiteDatabase db;

More interesting is line 100 in ContextWrapper.java, one line up in the

mBase is null because onCreate hasn't been called yet.

Re: [android-developers] Re: 3d engine advices
Make a source directory for the the following package that provides all the interfaces. javax.microedition.khronos.opengles.GL.java javax.microedition.khronos.opengles.GL10.java javax.microedition.khronos.opengles.GL10Ext.java javax.microedition.khronos.opengles.GL11.java javax.microedition.khronos.opengles.GL11Ext.java javax.microedition.khronos.opengles.GL11ExtensionPack.java Have your engine refer to only use these. Also have a factory method that returns your GL instance, I believe you already do. Now Android will then compile and work directly. Then for your JOGL version, have your App return an instance that implements the different GL objects. If you're engine is targeted at Android that allows you to dev on PC I think it's worth the time. First you're allowing the Android build to use the API directly. This verifies that anything you use already exists on Android. This means that you're only really managing the PC part which can have any hacks or performance hits required. It's just a suggestion, I looked at your code and I thought it was the best one I found.

In my app I inserted a row since a button in main screen and recover this row in a Service process. But, when I clicked in the button that execute the SQLiteDatabase.insert, the first insert didn't worked. Immediately after I tried insert the row, I can recover the row, but when I tried recover the row in another screen or thread the SQLiteDatabase return null.

One newbie question, If I would like that the SQLiteDatabase db
could use in other functions, how does I initialize in the OnCreate?
class MyActivity {
// Declare the variables in the class, outside any method

base baseDatos;
SQLiteDatabase db;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

[android-developers] Can we create UI component in a seperate XML file and load it
So I have created this activity, and setContentView() with mail.xml layout file. Now I want to add some textView dynamically into this screen. I already have these text view defined in a seperate xml file named view.xml. How can I instantiate these textview components and add them into screen? I know we have inflate method, but once we call inflate, this view.xml will be added to screen automaticallyhow can we achieve this?

What format is the $signature openssl_sign() outputs? Try to print it. My guess is that it's binary, whereas the signature you get from Market is Base64-encoded. If so, you need to decode the Base64 and it should work. Thanks, the openssl_sign() php function is just being used to verify that if I sign something myself, instead of using the Google returned version, that it works in my php verification code. The openssl_sign() does return binary and I am encoding it to base64 before using it elsewhere. -- You received this message because you are subscribed to the Google Groups Android Developers group.
