 How i can create android project's library that can be used in any
different project.

I create a jar file that contains all activities and add this jar file
into my eclipse project build path. But if i need to use any activity
then i must need to register this jar activity into my project
AndroidManifest.xml. This looks very odd. I need a solution in which i
have a jar or any other deployable file that contains multiple
activities and any user can use them in his project without
registering these jar activities into NEW android application
AndroidManifest.xml file.

That is not possible.

As I wrote 5 hours ago:

Bear in mind also that your library cannot package any resources, making
activities that much more difficult to package in a library.

You can see a library that I package with an activity here:

Anyone using this library will need to both list my MenuCustomizer
activity in their manifest, but also pass in a couple of resource IDs by
integer extras on the launching Intent, to get around the fact that
MenuCustomizer cannot have its own resources.

I'm not sure that is true.

I have created a .jar from a project that happens to include some
layout files.  I import this .jar from a second project, and add a few
lines to the second project's Manifest file:

android:name="com.googlecode.chartdroid.intent.action.PLOT" />
        <category android:name="android.intent.category.DEFAULT" />

When I launch the .jar'd activity from the second activity with an
implicit intent, it appears to work fine.  The layout resources that
the .jar'd activity uses exist only within the .jar file.

*blink, blink*

How do you have the resources packaged in the JAR?

 Oops, I'll have to retract that; my test was invalid.  The manifest
lines I added were incorrect (forgot the <intent-filter> tags),
causing my new version not to be installed...

I do indeed find problems in my log now, such as:
09-09 19:28:11.484: WARN/ResourceType(580): No package identifier when
getting value for resource number 0x7f060000


09-09 19:29:18.184: ERROR/AndroidRuntime(3002): Caused by:
java.lang.RuntimeException: Your content must have a ListView whose id
attribute is ''

followed by F/C.

Sorry for the mix-up!

I was also misled by the fact that I could reference the ID's of the
resources inside the JAR, suggested by Eclipse's autocomplete

I think the best way to accomplish what I was intending will be to
install an entirely separate .apk with the libraries.

2. cupcake 1.5 r1 surfaceCreated is not called!!!

I've created game,
everything works fine on all previous android versions except current
cupcake 1.5.
It works even on cupcake pre release.I'm using exact the same
build.xml, sources and resources.
The problem is that surfaceCreated is not called :
                SurfaceHolder mSurfaceHolder = getHolder();

                waitForScreen(); - here I untill surfaceCreated change variable 
it's ready,but it's never called.
I just can explain that I'm running SurfaceView activity after
stopping regular View activity (for the game menu - it was easier to
create it).

 Please help me if you can figure out something. I'm just a developer
not a Android engine tester. If they are putting such stuff to the
market they should test it a little bit (not talking about discovered
VM crashes instead of exceptions).
