r.java-file

问题 Recently I have been having quite some problems with R.java file. Now I have decided to do a backup and delete the file to see what happens. Nothing happened, so I created an empty R.java file and hoped for the best. Now Eclipse seems to figure out that the file was tampered with and even issues a warning: R.java was modified manually! Reverting to generated version! And that's all there is. I tried building it manually but got no results. So, I have two questions: what should I do to force

问题 I am trying to change my Eclipse project to make it backward compatible to Android 2.1. I followed the instructions to set up the Support Library from here but after I attached the Library project to my project, the R.java from the gen directory gone. Plus I got some errors in the console, like: [2013-09-02 00:08:26 - gitarshopAndroidClient] /usr/local/external/android-sdk-linux/extras/android/support/v7/appcompat/res/values-v14/styles_base.xml:24: error: Error retrieving parent for item: No

问题 My problem is that eclipse is not generating a R.java file even right after creating a new android application project so there should be no errors in my xml files. I double checked to see if there was any errors with the xml files. Also I have cleaned and rebuilt my project manually. I'm using eclipse 3.7 and adt 20.0.3.v201208082019-427395 Edit: Here is a screen from eclipse 回答1: If you think that your layout xml and manifest.xml is correct than might be your Android plugin is corrupted.

问题 I am sorry if the question title is a bit cryptic. I simply could not come up with a better one. I have a project where I wanted to play around a bit with the package name in the AndroidManifest. Please don't ask why I did it or why I did not simply use build.gradle's applicationId. The thing is, in order not to have to constantly correct the import for R.java everywhere when modifying the package name, I created a proxy class for R.java that looks like this: import static com.package.main.R.

问题 I'm trying to access each of the values in colors.xml, but the int (hex) values in the R/color class doesn't match corresponding values that are defined in colors.xml. Here are some sample values: R/color (all of which starts with 0x7f0400...): public static final int AliceBlue=0x7f04002d; public static final int AntiqueWhite=0x7f040023; public static final int Aqua=0x7f04007d; public static final int Aquamarine=0x7f040062; public static final int Azure=0x7f04002b; ... But in colors.xml (all

问题 I've began making a new project and just as I was linking my buttons to the java I noticed my R would not resolve and come to find out that my R.java file is not there. I've looked at other questions like this and they say to clean the project which I have done and it still does not work. Here is my code from the pages where it wont resolve. Thanks! Invoice Java package com.invoice; import android.app.Activity; import android.content.Intent; import android.os.Bundle; public class

问题 I'm working on my app and for this activity I was going to build a new layout file for it. However eclipse gave me an error stating that layout was not updated in the R.java file. So I read online that modifying manifest would update the R.java file but it didn't. So I clicked on clean project and my R.java file disappeared propagating errors across all my src files. Now I heard that it could be due to layouts named with capital letters but all my layouts start with small letters. Also even

问题 I'm using Android Studio v0.2.6 and I don't know why, but there is no R.java file created in my project. Therefore the autocomplete-thing tries to import android.R and everything is messed up. Is there any way to force AS to reset the project properties and try to recreate the R.java ? Rebuilding doesn't work, I tried a lot that was suggested in other questions. 回答1: I've had a similar issue - make sure your src, gen and libs folders are set as source folder in the Project Structure dialog.

问题 I've just updated the Android SDK to version 22.0 (well, more like a fresh install) and started a new project in Eclipse. I went through the project wizard and everything went fine but then I realised that it didn't generate the build files (neither BuildConfig.java nor R.java). I searched a bit and found others with similar problems and someone pointed out that after updating a new package should be available called Android Build Tools. I had installed them as well and BuildConfig.java
