How do I add the Chartdroid library to my android project? I have gone on their website to download the source code but every way I try to add the file to my project it just shows up as gibberish and gives me an error message.
If possible could you give an extremely basic/simple explanation on how to do this because I am very new to both programming and android platforms.
Try to get the example app working and understand how it works. Then create your own application on the level of a HelloWorld appliction which makes a simple chart from a static array of data. That should get you pointed in the right direction.

I'm very new to eclipse, and for a first project I want to make an android app. The problem is that every time I try to create the project, I get all these errors about 'Theme.AppCompact.something". I know many people have asked this question, but either I can't get it to work or I don't understand. If you could answer like I'm 5 or use screenshots that would be great (since I have been trying to fix this forever now).
I'm very interested about java and eclipse (coming from C# unity) and I want to start this android project but I cannot with this error.
I am new in developing apps for Android with Java Eclipse.
I get a simple problem: after following the procedure explained here:
http://www.tutorialspoint.com/android/android_hello_world_example.htm
I tried to push the "Finish" button to create my first app, but it doesn't work: the wizard remains open and nothing happens.
Also, I have several problems in the Demo apps, errors like:
'<>' source operator is not allowed for source level
and many more.
I guess I created problems with the configurations.
Thanks if you can help me to create my first app for Android and to load
the demos.
It is really had to tell what is the problem, but as Abdullah advised to use android studio because it is well designed to develop android applications. and most of the company's now days use android studio as there IDE preference, but still its developer's choice. Eclipse ADT plugin is buggy
I am new to android app development. I need to develop a very simple app that could detect coloured circles.Can someone please tell me in detail how to use openCV Circle Recognition code in developing a simple android app that can detect coloured circles. I am currently using openCV+ Eclipcs but it does not allow me to compile the source code in to .apk file
I have already done what u are saying...I have done the following
I download the full NVidia tegra-devpack-2.0-windows-2013-02-06-14961502 and installed It contains both android ADT for eclipse and eclipse also. It also contains the open CV and it automatically configures everything.
Everything works fine when I make a new android app like “my first HELLO WORLD app” and I can even install it to my android phone that means everything is working fine and everything is configured correctly.
The problem arises when I try to import the source code of the “CVCamera” an common app for detecting circles in android devices
When I import it in the eclipse as an android project from existing code it gives me following 2 errors
(a) Project 'CVCamera' is missing required Java project: 'OpenCV'
(b) The project cannot be built until build path errors are resolved.
I have tried lots of things I even tried to link the open CV library to the project but of no use
I have a simple objective I want to develop an android application for detection of coloured circles by using the already available code on the web. Please help me in achieving the following
I am using openCV4android . I can even create new apps but the problem arises when i try develop the application by using already made source code. I am using the sources code of the CV camera app which has been already developed by so many developers Following is the link of the error I am getting in the eclipse.
Please see the image
Following is the link of the CV camera application which I am trying to import

Here is the link for another error “Build path entry is missing: OpenCV”

Use opencv4android in eclipse.
Before that you should deploy android ADT for eclipse, or download bundle for android dev.
Then follow the tutorial at opencv official site to start your way to android.
Use hough transform for circle detection.
You must link JavaCV lib into your project rather than OpenCV.
Android app cannot use OpenCV(C++) unless you use JNI, which is far beyond the scope of this question.
So please follow the tutorial for using JavaCV on Android rather than doing the import stuff on your own. Please make some JavaCV examples compile and run on your phone before you try to adapt the code.
Besides I strongly recommend you use openCV4android, which is sure to work, rather than JavaCV + Android, which takes your considerable time coping with configuration and integration.
I am implementing menus using TWL (http://twl.l33tlabs.org/) in an app written using Libgdx. The app runs fine if I don't start any menus, but as soon as I go to a menu screen it immediately force-closes. Menu screens work fine on the desktop version.
In which build path should TWL-android.jar be included (right now it behaves the same in main, android, and both)? And how will the program know to use the libraries from this .jar instead of the default gdx-twl.jar? Will I have to manually implement something in code to use one or the other depending on platform?
There does not seem to be any documentation or sample code of anyone using TWL on android, only mentioning that it can be done.
Running debugger attached to phone gives the following logcat error:
Could not find class 'com.badlogic.gdt.twl.Layout' referenced from method com.Nanners.OptionsScreen.<init>
I think that TWL-android.jar should be added to android project's build path too. Location of .jar is not relevant.
When you add TWL-android.jar. As that is Android specific you can't use it on the core project, so the classes you are importing are the ones from gdx-twl. To make it simpler to explain I will divide it in different escenarios.
You add TWL-android to your Android buildpath. But you use Gdx-twl in your core project. Which isn't added. Thus getting a:
Could not find class 'com.badlogic.gdx.twl.Layout'
You add both TWL-android AND Gdx-twl to your build path. Thus getting duplicated classes and:
Conversion to Dalvik format failed with error 1
Solution
If you use TWL-android classes, you can only do it inside the Android project:
Merge Core, Desktop and Android project. Or
Use Interfacing with Platform Specific
If you use Gdx-twl:
Don't do it.
Actually the best solution is to get rid of all twl stuff and use Scene2d.Ui instead. Its crossplatform and much easier to use.
I am new to android. I am using zxing in my android project natively. I followed the steps here. But I get get classNotFoundException for capture activity of zxing lib when I call intent calling zxing android client. Also note that when I add capture activity project as library, firstly it adds properly, then when I say apply/ok & later see again then i see red x mark for this added lib. Even the src folder of added lib is not seen in source tab. I think there is some problem while adding lib but I don't know what & how to figure it out.
Please suggest.
Thank You.
The problem is that you are trying to use android/ as a library, and it is not a library. You are not supposed to copy this code and try to call it in your app. Instead, write your own app. Then integrate the core library (just core/) for decoding.
If you're new to all of this, you will probably have a lot of difficulty getting this working versus just integrating by Intent: http://code.google.com/p/zxing/wiki/ScanningViaIntent
