Hi I am completely new to Android programming and the question I am asking might be something very simple, but I do not have any idea about how to make it work, so kindly be
- First of all please make sure that you have properly synced Eclipse with Android.
- Have you added the tools
, and platform-tools
folder Path in your System Environment Path.
- I hope you are creating an Android Project and not Java. See the Project folder in the Project explorer in Eclipse will be having a A
sign for Android and J
for Java.
This is build issue.
Go to Menu in eclipse, Project>clean then Project>Build All
Clean instruction will remove all build configuration and fix all build issues.
Project --> Clean worked for me
what worked for me:
Eventually i checked back Build Automatically.
I do not know what`s with "Build Automatically", It gives me some problem also when i export my Google play games (especially when i used external libray, like AndEngine for instance).
To fix it, i do a similar thing to fix the problem (uncheck it, clean, build manually)
I had a similar problem. But is was caused by crashing of eclipse. After that I was 2 swap files of AndroidManifest.xml and the same error: "AndroidManifest.xml file missing!".
So, I removed swap files (.swo, .swp)
:-)
Just build your project or Clean it as "Clayton" mentioned below.
Project > Build All
Project > Clean
This I believe is because you do not have R.java file in your gen folder. Building your project will generate the R.java
file in your gen
folder and the errors should go away.
This happens because you're referring to your layout file using the following code
setContentView(R.layout.activity_main);
The reference to R.layout.activity_main
is declared in R.java
file which needs to be generated by building your project.
