Because you can't... breakpoints need to be placed on code that actually

What I did was I put a method breakpoint on this line:
public void handleMessage(Message msg) {
It did not get triggered when that method was called.
However, when I put a breakpoint here:
Log.d(hmmm,hmmmok);
It breaks as it should.

[android-developers] ProGuard docs are inconsistent with the actual config files
I'm working off these instructions, which as you can see are a proper and formal component of the official Android dev docs: *http://developer.android.com/tools/help/proguard.html* (Side-note: that file has no date written on it and no applicable Android SDK version written on it; it is temporally unresolvable. Perhaps my problems arise from the fact that the docs are out-of-date, but there's no way to know. Those docs could be four years old for all I know. Online files should always be dated.) At any rate, near the top of those docs, just trying to get started with ProGuard, it says this: *To enable ProGuard so that it runs as part of an Ant or Eclipse build, set the proguard.config property in the project_root/project.properties file. * First of all, it would be helpful if those docs would offer more up-front information about how to get the crucial proguard.cfg file to appear in the project directory. I found out that I needed to run this: $ android update project -p . -t 6 ...but that was in rather tangential documentation (a StackOverflow discussion if I recall correctly). Regardless, the next step as described in the docs is to edit project.properties, but if I open that file, I immediately see the following warning: *# This file is automatically generated by Android Tools. # Do not modify this file -- YOUR CHANGES WILL BE ERASED! * ...which is where I currently stand, rather stuck as you can imagine. The docs say to edit that file, but the file clearly says not to edit it! This overall process does not appear to be adequately documented and I'm not sure how to proceed. Does anyone have any thoughts on how to best get ProGuard up and running with an Eclipse based Android project. I'm finding a lot of casual discussion online but little in the way of formal procedure. Even the formal Android docs I'm working off of seem to be incompatible with the circumstances, as I just described above. I understand it sounds like whining to complain about these problems, but the official docs on *http://developer.android.com* don't match the do-not-edit warning in the actual files generated by the Android SDK and I honestly don't know what the next step is. This is a troublesome inconsistency. I would be very grateful for any help in getting this going.

Since I need to implement release / debug dependent code changes I was thinking that using Ant would be a good idea.

[android-developers] Re: What happens in android device.If gps is working for a long time continously (more than 5 hours)
I call BS. While the GPS on the phones is not as sensitive as the one in handheld devices etc (due to design limitations in the phone body etc) there is no way that a permanently running GPS (assuming the usual 1Hz rate of consumer gear) can have ANY impact on the phone hardware. Granted, it will suck the battery dry, but if you leave your GPS running continuously like you do for road navigation then you are most likely connecting your device to a power source anyhow. Don't let anyone tell you how often to update the GPS position. Make that design decision yourself, based on the needs of your application and the expectations of your users.

[android-developers] Re: Advice for a strategic game map
If you want to use 3D graphics then you need to brush up your OpenGL knowledge and optionally use one of the available game engines out there that also support Android. If it's 2D and performance is not a big concern then you can write your own custom View for that map (you also could create your 2D game in OpenGL by the way). Your custom map view would: - respond to touch gestures through View.onTouchEvent - Pinch-to-zoom - panning - touching game objects for interaction - have an internal representation of the game map - ...which could be composed of a grid of X * Y tiles - Or it could be one big space image - Preferably also split in tiles so you can stay compatible with older Android version that don't have android.graphics.BitmapRegionDecoder - have an internal representation of all game objects and their positions: - ships, planets etc. - have an internal zoom factor - x/y coordinates of the current map translation - This is the point you are looking at right now on your map - implement onDraw to: - render the currently visible part of the map by: - draw the background first - draw the game object - draw the UI in the end On Saturday, November 10, 2012 10:44:07 AM UTC-6, tlegras wrote: Hi, I am starting the development of a strategy game.

[android-developers] Re: [Using Ant] BUILD FAILED: com.android.ant.SignApkTask cannot be found
Ok, I figured it out. I had a misconfiguration on my box that caused the JAVA_HOME variable to point to an old Java version (JRE 1.5). I corrected the path and now it works.

Re: [android-developers] Re: Application onCreate called more than once?

[android-developers] Load an error resID after devices just started.
hi all: I get strange problem with .R class while devices just started. my app get all kind of broadcast and send a notification. but some times, after devices has started, my app receives the first broadcast and send a notification with wrong layout id. and it cause my app crash forCouldn't expand RemoteViews for. I have checked my code that the notification's layout id never be changed. but why it change a nother id, and it just occurs after the devices started. Are there any clues can help me find the root cause? All are welcome to give your ideas -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Confused about signature process to verify purchases
After any exchange between the app and Google play to purchase some goods,
the app must then forward this request to some external content-delivery
server requesting that the purchased goods be delivered.
Obviously, there is no way to prevent the user from modifying the source
code of their app from simply sending any arbitrary message -- such as a
purchase was successful message to your server (obfuscation may slow down
attackers, but isn't truly secure).
Therefore, the only way to be secure is if the purchase successful
message has been digitally signed by Google play. The only mention of this
I found in the documentation is here:
http://developer.android.com/guide/google/play/billing/billing_integrate.html
where it says: *Your application must also provide a way to verify the
signatures that accompany every PURCHASE_STATE_CHANGED broadcast intent.
The Security.java file in the sample application shows you how to do this.*
Now, if we look at the source code for Security.java (inside the Dungeons
example they are referring to), then we find the verifyPurchase function,
which contains this code:
/**
* Compute your public key (that you got from the Android
Market publisher site).
*
* Instead of just storing the entire literal string here
embedded in the
* program, construct the key at runtime from pieces or
* use bit manipulation (for example, XOR with some other
string) to hide
* the actual key. The key itself is not secret information,
but we don't
* want to make it easy for an adversary to replace the public
key with one
* of their own and then fake messages from the server.
*
* Generally, encryption keys / passwords should only be kept
in memory
* long enough to perform the operation they need to perform.
*/
String base64EncodedPublicKey =
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAqiPOV7jXSWomX32h9KYRfWXOLEbmakAQJhq5lq1j1tEC3Tz8qvO9RUAmaCKF1x51Wyc5zI4weX5N1Wix/RdpvAFPk4O5PmGcCpA78grFMPFLZtwI9R1cOtlOSwoRBMc2PDdGVWsLWyWoNhsnkOXMvfOk78daT0reFFFdMPmACzROcwcW/Dq+gkE4sTb2fgtLlYLOAy186PTHuES+j+532jbuOBFLLVw64UYjTcP29LdIVC/XBvqqiMdMLeDblvQyQVhoQcFvOwf0+k0ZJUdNcZcJXgQJC0fsMOaWu/aTzqm5fqQcboYDko/lG76+lNqS71wkWefKAzzkGHjyrZS6AwIDAQAB;
PublicKey key =
Security.generatePublicKey(base64EncodedPublicKey);
verified = Security.verify(key, signedData, signature);
if (!verified) {
Log.w(TAG, signature does not match data.);
return null;
}
Now, this seems odd to me...because they are using OUR OWN public key to
verify the signature. The Security.Verify would verify that the supplied
public key had been signed with the corresponding PRIVATE key. But Google
Play does not have access to our private key...so how could they have
signed it for us?
Secondly, it does not make sense to do verification on the client side.
The verification needs to be done by the content-delivery server, to verify
that the message came from Google Play -- which means that Google should
have signed it with THEIR private key.
Please help me understand how this makes any sense!
