Android 2.1: my account authenticator causes phone address-book to crash

I am creating a new account using AccountManager and it works fine for android 2.3+ but for android 2.1 it makes the phone's address-book crash when trying to view a contact details.
The account is defined like this:
type: com.example.android.authenticators.ABCAuthenticator.account
name: Contacts ABC
The crash I see when trying to open a contact's detail activity (not on my app, which works fine, but on the Motorola 2.1's native contacts app) is:

It seems like it tries to find the authenticator but it does not find it... but why? Are there any limitations on the name / type of the authenticator for Android 2.1? Any ideas?

Turns out my sync-adapter was using a #string reference for the android:accountType attribute and for Android 2.1 it needs to be a hardcoded string, not the reference.

ActivityNotFoundException when include Android library

I have a test project which uses OI FileManager. I added that project to my test project as an Android library, then I call an Activitity in the library. It shows error:

When I add full path of that Activity in the Manifest, it generates another error.

It shows:

W/ActivityManager( 59): Force finishing activity com.androidcoretest/org.openintents.filemanager.FileManagerActivity
I would say this is a bug of Eclipse. Eclipse and ADT recently have many bugs on building process: ClassNotFound and ActivityNotFound.
Update:
My code just use one line:
final Intent intent = new Intent(FileExplorerTest.this, FileManagerActivity.class);
startActivity(intent);
Actually I have 3 projects. 2 library projects and 1 test project. Library "OI File Manager" uses Library "OI Distribution", then the test project C uses library "IO File Manager".

Ensure you are linking the OI FileManager projects as a library rather than external jar. go to Project properties > Android > Library, then click add library.
Then as you are doing define the activity in your project manifest (however with ADT 20 i think this is automatic)
<activity
android:label="#string/app_name"
android:name="org.openintents.filemanager.FileManagerActivity" >
</activity>

I guess it can't find com.androidcoretest/org.openintents.distribution.EulaActivity not the FileManager activity. Do you have that EulaActivity in the manifest?
See in your log:
Caused by: android.content.ActivityNotFoundException: Unable to find
explicit activity class
{com.androidcoretest/org.openintents.distribution.EulaActivity}; have
you declared this activity in your AndroidManifest.xml?

Try to chek from your ddms data -> data -> your package ->database
here you will find that table is created of not.
also it you pull it out and open with SQllite browser u will get all the table list in it.
Hope this will help you

You should be extending SQLiteOpenHelper for your database code if you are not already.
Then check that your onUpgrade() method also calls back to your onCreate() method. You may be dropping all your tables and then not re-creating them. Make sure you bump the database version number every time you make a change to your tables.
The google iosched app has a complete, if not slightly complex example of how to do this.
http://code.google.com/p/iosched/source/browse/android/src/com/google/android/apps/iosched/provider/ScheduleDatabase.java

Actually i had to uninstall the application from the emulator .it worked fine after that

Can anybody understand from the above log what exactly is causing this error?

How to fix android.os.DeadObjectException android X
this guy met the same issue, check this link out.
I copyed the answer written by Dimitar Dimitrov as follows
This means that your service had already stopped - either killed from
the OS, or stopped from your application.
Does this problem happen every time you debug your project?
Override your service's onDestroy() method and watch what event flow
leads to it. If you catch DeadObjectException without going through
this method, your service should have been killed by the OS.

java.lang.ClassCastException in Android

Started getting a ClassCastException in a widget I've been working on that I'm not sure what it's having an issue with. I haven't modified the configure class, nor the configure layout, yet I've started getting a stack trace leading back to my configure class after modifying the main layout

Reverting my changes causes the issue to go away, but I'm not doing anything with this file, nor am I modifying any RadioButtons...so what the hell? The line #39 of Configure.java is
EditText prv = (EditText) findViewById(R.id.previous_input);
I don't see how that ties into anything. And the only changes I am making to the entire project are changing some TextViews into Buttons in my main.xml layout which is not referenced in Configure.java. Reverting the Button back to TextView makes the error go away. What causes a "ClassCastException" and what could possibly be going on here?

Try clean your project. Previously you had RadioButton.
