Hey guys.
I'm an experienced .NET Developer and developed with java a little. I want to start developing Android apps on Windows.
I downloaded everything and my app runs, but once i debug it i get a strange error: "The JAR of this class file belongs to a container "Android 2.1-update1" which does not allow modifications to source attachments on its entries".
While looking on the internet to find a solution i came upon a few blogs that explain that i need to get the android source: http://stackoverflow.com/questions/...-container-android-2-0-1-which-does-not-allow
I'm having an immense headache getting it because nothing works. There's no simple guide to do this.
If any of you know the error and can help me solve it i would appreciate it.
Also, if you know how to get the source please let me know. I'm going crazy here.
Thanks!

You say you downloaded "everything", but not what "everything" is. For mainstream development (using only public API), you don't need the Android sources.
Get the SDK, and Eclipse ADT if you want the most straightforward environment, import one of the example projects, and get it running on the emulator/device. It's pretty much all explained in this tutorial project. Then you can see what's up with your particular program. Good luck!
I have Eclipse, the latest ADT and the latest SDK. I installed the packages for 2.2 and 2.1 with the Google APIs.
I'm trying to make a simple tip calculator app. If i don't make a certain check in my app everything runs ok. As soon as i check if 3 EditTexts have text in them i get that error.
If i don't need to check, my app is behaving ok.
if(txtbillamount.getText().toString().equals("") || txtpercentage.getText().toString().equals("") || txtpeople.getText().toString().equals(""))
{
...
}
The hello world apps works fine.

Do you have an else statement?
Yes I do have an else statement. I display a pop up message in the else statement.
I would recommend getting acquainted with a little bit of java code as it is very different than .net
Your dev env seems too be ok since, The hello world app works ok as you stated, its your coding.
Coming from.net programming it was confusing for me at first.

Problem solved.
Yes, i was coding something in a wrong way. Java is different in many aspects.
Thanks.
I'm trying to build an android app that reads and write a users google calendar. I'm trying to follow the google example at http://samples.google-api-java-client.googlecode.com/hg/calendar-android-sample/instructions.html?r=default but I'm stuck at the step trying to install Package "Google API's by Google Inc., Android API 8". When I go to the installed packages screen there is no package with that title. If I try to update I get the following message "Some packages were found but are not compatible with update." What do I need to do to get the package listed in the sample? Sorry for the newbie question but i just can't figure it out and I've googled for that package name and nothing relavent was returned.
Thanks

Firstly, I don't know if this is a right site/forum to ask this question but this seems to be most active android development forum when googling for 'android development forum' even though this site seems to be mosty about rooting and mods which is not what my question is about.
I'm trying to compile github.com/corbinlc/GNURootDebian from source and make it run on my android emulator. I get 'Configuration with name 'default' not found' in android studio 3.0 when just opening the project. Can anyone help me out tackle this error?
> I tried googling / stackoverflow and couldn't find a satisfying answer
> I have successfully built and run a simple app in emulator using steps outlined in 'Building Your First App' walkthrough on developer.android.com/training/basics/firstapp/index.html
Thanks in advance,
Hi all,
I have a rooted phone and flashed many files and installed many apps but I don't not have a fundamental knowledge on Android. When trying to research I only find "developer guides" with the aim of building applications however I would rather understand what Android is ? What flashing files do? Why we flags .IMG files? What Google framework is ?
Totally random questions but they came to my mind. If anyone understands what type of stuff I'm talking about please share.
