I am new to android but when I run the eclipse (which I installed ADT Plugin and android SDK) I found that my eclipse is not generating R.java file with a error message(as shown in figure)
How to rectify that ?
Thanks in advance
You should download the android bundle here http://developer.android.com/sdk/index.html
It is and eclipse version with everything needed for android already installed.
I had the same trouble as you, switched to this one and everything worked at the first try

I just tried to install Android SDK into Eclipse Oxygen.1a Release (4.7.1a) and I just generate the first Android project... "Hello world".
I connect my device, try to run it...and Eclipse show me into the console
"Failed to load C:\Users\Luca Lombardi\android-sdks\build-tools\27.0.0\lib\dx.jar"
"Unknown error: Unable to build: the file dx.jar was not loaded from the SDK folder!"
I checked into this folder, but the dx.jar already existes into this folder!
I already tried to:
Clear the cache and reloaded the package
Tried to install again the Android SDK
Copy the dx.jar into the folder
But nothing has work properly.
Have someone some ideas in order to fix this problem?
I don't beleive that is so difficult start to develop on android...
It happened to me, I also installed the latest Android SDK Build-tools(V 27.0.0), now I have changed to old Android SDK Build-tools(V 25.0.3). now it is fine for me.
new path:android-sdks\build-tools\25.0.3\lib
I am facing a so weird issue with my eclipse. Android projects are not running in my eclipse
I'm using
Eclipse version 4.4 Luna ,
android SDK latest API level 23
(even earlier versions is not working ).It was running well till some days ago , and all other java projects running fine like web and desktop etc..
Whenever I am running the android project it shows the error dialog box, though no errors are there in the project(for a new project also), I have tried clean build, cleared cache, updated eclipse adt , and is there anything left I need to try other than formatting PC?
Well ,after some struggle I have found out what is the actual problem. It was my debug.keystore file.
I have got an error in my console saying Debug certificate expired
Well I have found my debug.keysotre file in here %USERPROFILE%/.android and deleted it. Eclipse itself will generate a new one when compiling a new project. You may need to clean and then build to generate the certificate.
Thanks everyone for your support.
Problem solved !!! :)
Can we use Android studio for AOSP(Android Open Source Project) development, is there a way to do it. I didnt find one. anybody got any idea on this please ?
You can use Android Studio as a IDE for AOSP, since it's just a modified version of InteliJ's IDE.
from AOSP root:
make idegen && development/tools/idegen/idegen.sh
Then just "Open Project" in Android Studio and select the android.ipr it generated.
To import AOSP source in Android Studio or Eclipse, follow the full instructions here :
https://android.googlesource.com/platform/development/+/master/tools/idegen/README
What Pedlar suggested above is one way of doing it. I ran into lot of Jar dependency issues when I tried it with IDEA community edition (Android Studio is a fork of IDEA IDE). The IDE keeps prompting you about duplicate jars etc. The generated project includes framework Java sources as well as App sources. I tried to build an App project which resulted in broken AOSP build. IMHO, IDEA is a great IDE for Java development. But didn't work well with AOSP.
What worked for me is using eclipse to browse/edit/debug framework sources, but build the code from a terminal window. To avoid AOSP build breaks, please create a shadow dir of AOSP (i.e. lndir of AOSP) and use shadow dir for eclipse project.
This is explained at Using eclipse to browse/edit AOSP link in step by step.
If you are working on AOSP, you might want to check Debugging Android framework services.
Hello i am trying to run EBookdroid reader on my eclipse. I have downloaded all source code.
I copied all project to workspace and then imported to eclipse but when i import project into eclipse there is no R.java file generated.
I tried to clean project but still with no luck. There are shown some warnings in build.xml, but i don't think that this is important generating R.java file.
Maybe someone had this problem i could help me.
Thanks.
I tried to do the same thing few hours ago. Still cannot run ebookdroid properly but at least the R error portion has been cleared.
In short, check if you have android sdk correspond to target=android-xxxx
For me, after I install Android SDK 4.x and 3.0 and 3.1 via Android SDK Manager, that error dissapear
I've looked for an answer, no luck. Looked a lot.
I've downloaded an android example project from a friend, it's all in the correct layout, and the source files are there. Only I wish to open the whole project in eclipse, so that I can run it using the emulator I have installed. However, I cannot seem to be able to do this. I have all versions of android installed, and I have been advised that the files/project are for 2.3 so should be good. Have tried:
File --> New Android Project --> Using the existing file and build path
It suggested to do file --> Import instead, so went there and imported an android project from existing workspace.
It gave this error:
"Project has no default.properties file! Edit the project properties to set one".
Any help is much appreciated!
New version of ADT plugin uses project.properties while older version use default.properties.
Please upgrade ADT plugin. It will work
I had this problem when trying to open one of my projects on a different computer, you need to update the ADT. In Eclipse go to Help > Install New Software. Type in https://dl-ssl.google.com/android/eclipse/ and install the latest versions of everything. Also make sure everything to do with the SDK is up to date!
Try creating a new project from existing source.
