Android in-app billing example, wrong source files? - android

I downloaded the Android in-app billing example and imported it into Eclipse. After import I see some strange errors.
There is a source file AccelerometerPlay and the string resources in the Dungeons.java file are not existing.
It seems that the download got the wrong resources. Has anybody seen this and knows how to get the right code?
Of course I can put in my own strings to get rid of the error markers, but I cannot say if something else is missing. So I'd rather have a correct version of the code.

How can I take over this question? It is not resolved for me and I can not up-vote it or comment on it stating this still persists for me. Duplicating the question can't be the solution neither.
More details:
The Dungeons example is not in "Extras/Google Market Billing Package" as shown in the screenshot in their tutorial but in "Extras/Google Play Billing Library"
The version of this is "revision 2".
After removing it via the Android SDK Manager various times and adding it again to re-create the project from source within Eclipse, I now did check the "create Activity .Dungeon" checkbox in the last step and think that did the trick. I'm not eager to verify this assumption ending up without a broken project again though.

In Eclipse and Intellij, if you create a new app over those existing sources (and presumably have it create a default activty like "MyActivity") it will overwrite some of the billing files namely the main layout and the strings file.

How do I properly implement Google Play Service Achievements?

I've been searching for a couple of days, including on this website. What I have found would be useful, however I find that I'm unable to follow them correctly. The questions here have no answers either.
Firstly, when I attempt to add BasegameUtils to the project and import whats needed, Eclipse cannot find them. I don't understand why, because I have imported it and marked it as a library.
This is not helped by the fact that all of the examples have their mainactivity in the folder where the API is. I have already built a full application, and I do not understand where I'm supposed to put mine.
The whole thing is incredibly confusing, and any help, or examples would be lovely.
https://developers.google.com/games/services/android/init
You need to implement baseGameUtils as a library or module depending on your IDE.
public class Main extends BaseGameActivity
And then you call this to unlock the achievement.
Games.Achievements.unlock(getApiClient(), getString(YOUR_ACHIEVEMENT_CODE));
These code samples really helped me first time round.
https://github.com/playgameservices/android-basic-samples/tree/master/BasicSamples/libraries/BaseGameUtils
The tricky part isn't the code, it's the configuration of your project, make sure to check on the play developer console that you have set up your testing account properly and your achievement codes are correct etc.
Okay, the solution was not simple. The guides seem to favour Android Studio, which implement a script to create BaseGameUtils. The BaseGameUtild that I was importing with Eclipse was not the correct one. I ended up searching for a valid one, and downloaded it.
The second thing I was doing wrong was not updating the SDK to version 20. Now, with the Play Services Lib in the extras, I could import the updated version.
After that, I discovered that gms.; actually must be written as com.google.android.gms..;. With this in line, I am now able to properly implement everything.
Thank you to those who helped.

"Package file is invalid", solution from the developer side (Android)

I'm tired to see a lot of Stackoverflow questions about this, even in Google forums or Google official support site, publishing "solutions" that lead to uninstall package through ADB, to do something with the phone rooted, to delete cache of Google Play Services, etc ...
https://code.google.com/p/android/issues/detail?id=64514
https://support.google.com/googleplay/answer/3300875?hl=en
http://gizmostorm.com/how-to-fix-package-file-is-invalid-error-on-google-play-store/
https://www.google.com/search?sourceid=chrome-psyapi2&ion=1&espv=2&ie=UTF-8&q=android%20upgrade%20download%20invalid%20package ...
etc ...
Is there any solution from the package side ?
I mean, I have an app with hundreds of thousands of installs, and unfortunately many users are complaining about this error when upgrading from store my new version.
Obviously, I can not go one by one telling they have to do this or that, because they are not developers, they just want to upgrade and run an app !
Some users are telling me (complaining) this happened since the last "upgrade attempt" of my app, and they are not experiencing this "package file is invalid" with any other app in their phones.
So, I guess it's something I can fix with another upgrade.
Is there ANY SOLUTION that I can do in the next APK compilation, uploading to Google Play Store and fix this without "bothering" my users ?
Thank you in advance
I have also faced same issue in my project as well. I was adding many more features with new jar, git open source library code for Nice UI.
For searching for solution I found play store has issue in one of its updates
http://www.androidcentral.com/google-investigating-package-file-invalid-errors-google-play
But this is totally not relevant to my problem
Again searching I found this
http://birbit.com/how-to-solve-linearalloc-problem/
So the solution looks to be loading a few jar files dynamically using DexClassLoader.
http://android-developers.blogspot.in/2011/07/custom-class-loading-in-dalvik.html
Prepare Interface of the jar file (list of all classes and methods) and have the interface in the app - Need to see how to do this. - We can just have those classes which we need in our app and ignore the rest of the classes. This way we can implement for few existing jars and any new jars that we have to add to make sure we don’t run into this issue again.
Keep the jar in assets folder
Load every class from the jar (based on the list of jars we have in the interface). (The classes will be loaded just once on first launch)
But Based on this, this looks to be involving lot of coding changes and a time consuming things.
Moreover I found that facebook also faced same issue in their initial android app
https://www.facebook.com/notes/facebook-engineering/under-the-hood-dalvik-patch-for-facebook-for-android/10151345597798920
Final Approach I took was removing additional code from jar/git library project which is not require for my application. after that my app got install on 2.3.X with no error.

Android ActionBarCompat Not working from the start

OK, I have been wanting to try the new ActionBarCompat, however, I am not able to run my programs in the emulator.
I have been trying to implement the following: http://antonioleiva.com/actionbarcompat-how-to-use.
and have been stuck on basically the first part. However, working with the author of that content, I was able to get further as I was not adding the project under sdk\extras\android\support\v7\appcompat folder like stated. However, I still think that might be the reason I cannot do this...
More detail can be found here: http://antonioleiva.com/actionbarcompat-how-to-use/#comment-43
Basically, on my first attempt, I just created an Android project, and changed the source code as indicated. Code would not run on the emulator. So I went back to the original code, and that ran on the emulator.
Checked online, found out I might need to add the \extras\android\support\v7\appcompat folder as a library to the project I am building. So I added that and a new android project was created. There were build errors from the start, but I failed at trying to add it as a library to my project, and deleted it....thinking this was way overboard.
After back and forth chats with author of linked website, I found out I had to do that overboard thing.
So I tried the following link to the T: (I cannot post more than 2 links due to low repuation...I will add this link as a comment below)
However, Eclipse would not allow me to add the appcompat Existing Android Project...but it did allow me to add the appcompat Existing (General) Project. I think this may be some of the problems??
Right now, I cannot run the project at all. Eclipse is showing a red exclamation mark on the project folder, but all the code seems to be fine. So I don't know what to do now...I recreated this project several times over, and this one was the one where I knew what to do...and I am still getting problems
So...
I decided to move to Android Studio...updated the IDE, updated the SDK manager to include the new support library, and other things. Created a new project, added to the build.gradle file as shown in the link provided below in the comment. I ran the ant build, and then built the project...tried to import the right things to allow ActionBarActivity, but I could not get that far.
I can import
"android.support.v7.*"
"android.support.vy.R" // and all folders within
but nothing allows me to add ActionBarActivity, and I don't know why.
FYI, I guess I would prefer a solution to Ecplise, as it seems like I actually got somewhere with it.
The best example to use is from here, and I would follow it closely. I had similiar issues when I first came across this. Problem was I misunderstood what I needed to do

is there any automated refactoring tool that produces a unique android application?

I have a project template , when i want to produce a unique application manually to update it to the market. I will follow these steps :
Right click in the package name
Refactor, then Rename
Renaming the package in minifest then update the version code
finally to clean the code from imports errors such as *.R; errors
My question is there any tool that automate this refactoring process without being involved on it ?
i tried to create a java tool but it consumes memory and some things i have to finalize it manually , i'm searching for this since 3 days and nothings gives you a clear answer.
My question is there any tool that automate this refactoring process without being involved on it ?
The new Gradle-based build system can handle this scenario. In fact, it allows you to separate the package name used by R.java (to keep it consistent) and the package name used for determining whether the app is unique on the device and in the Play Store.
I recommend that you watch "The New Android SDK Build System" video from the Google I|O 2013 conference to learn more about what it can do, as Xav definitely covers this scenario.
Note that while it is not a "right click", it should make scripting a solution fairly easy.
Thank you all, I've solved this problem by converting the template project into JAR and let another small project handle every thing , I've created a small method that updates the minifest in that small project and i had to update package,ver name and ver code ONLY ,then I've generated the APK using ANT ,however i tested the project and it works fine , hope this will help another people

Library based application installs 2 APK files, not one - Why?

I am trying to restructure an existing app so that, except for a few override-able methods in a derived activity, all code will reside in a library. This still doesn't work for some reason, but in the process of attempting to troubleshoot this, I discovered much to my dismay that there are two .apk files installed, not one (when I run a debug session from eclipse):
The first (and larger file) is
having the original library name.
The second (only 20KB in size) is
having the derived application name.
Why is that and where can I learn more about this?
Could that explain the ClassNotFoundException problem I am having?
I found the answer myself. It turns out that I had 2 critical settings in the Properties of both projects not set correctly:
In the library project, "Is Library"
was not checked for some reason. I
could swear that I checked it, but
knowing how whimsical the Android
development environment under
Eclipse can be, I suspect that it
was unchecked by Eclipse (or the ADT
plugin) as a result of some glitch.
In the application project, I
neglected to add my library project
as a reference via the Add...
button. (how dumb could I be?)
Hoping this can be useful for other newbies to come.
