I just started Android programming using the Android Development Tools (ADT) plugin for the Eclipse IDE, and while experimenting with layout weights, I came across a weird error after running the program.
The console dump showed this :
2011-09-25 14:21:10 - HelloLinear] Error in an XML file: aborting build. [2011-09-25 14:21:11 - HelloLinear] res\layout\main.xml:0: error: Resource entry main is already defined. [2011-09-25 14:21:11 - HelloLinear] res\layout\main.out.xml:0: Originally defined here. [2011-09-25 14:21:11 - HelloLinear] C:\Users\Mukul\workspace\HelloLinear\res\layout\main.out.xml:1: error: Error parsing XML: no element found
Also, I noticed that there was a new XML file called main.out.xml created in the res\layout\ folder.
The reason you might get this error is that when you run the program you might have the main.XML file open as the active file. Eclipse (presumably) tries to run the XML file as the android application rather than the class file. The solution to this is pretty simple
1. Delete the main.out.xml file (generated during runtime). You’ll find it in the res\layout folder
2. After you are done editing the main.XML file, save it and switch the view to the java file which is accessing the main.xml that you’ve edited
3. Run the program and voila! – the error disappears
