symptom

I have the android workspace for a while. I have over 30 projects. I have tried to create a brand new project yesterday. There are no errors on any individual files. However there is an error on the project name.

You say check the error page

I have over 3000 errors in there due to other projects. I just couldn't delete all of them. Even if I do they get regenerated. May be there is a way to turn off auto build and just build the single project.

so what did I do

I have removed the single project that is causing the 3000 or so errors. That reduced the errors to 20 or so and I can see in the error tab what is going on.

Here is a reference to stackoverflow on this subject

Possible suggested reasons


a different keystore from the original
wiping user data on the emulator
Just a plain uninstall

Not sure what the reason is

I have used a different emulator and that seemed to work

Very interesting....

Here is what happened....Errors in 'res' sub directory will prevent from R.java being created

First of all make sure there are no errors in the resource sub directory. This will prevent from R.java being generated. In my case I have an error in the namespace declaration of custom attributes. Once I fix that it worked.

here is an example


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:apptemplate="http://schemas.android.com/apk/res/com.androidbook.custom"    
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

Although it is just a name space it seem to care what that path is to match your package name!!!

No I was wrong...here is the real scoop

The namespace shouldn't matter and in a way it doesn't but it does!! Here is why. Take a look at the following


<com.androidbook.custom.MyTextView
   android:id="@+id/custom_text_id"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="Debut Text Appears here"
    apptemplate:custom_text="Custom Hello"
    />

and see the argument "custom_text". The id value for custom_text is required to generate the R.java. By looking at "custom_text" there is no way to know if that came from the current package or a different package!!!

So the tooling relies on what is after "/apk/..." to locate the id definitions for that variable. So it should then represent your package!!!
