java.lang.NoClassDefFoundError on an Activity - android

I receive a crash report from my production app, which tells me that there is an NoClassDefFound Exception on one of my activity.
The exception is thrown on this line:
final Intent i = new Intent(MainActivity.this, SomeActivity.class);
Where it claims that "SomeActivity" class is not found.
There is only one instance reported out of thousands of users. (On a Samsung Note Mini)
Which means it shouldn't be a compilation or wrong lib included issue.
Is there any clues for me to continue my investigation?
p/s: The activity is definitely defined in manifest. Else it won't even works on other user's phones.
Stack:
java.lang.NoClassDefFoundError: com.sensored.SomeActivity

1) Keep all activities under same package[say com.compname.proj.views].
2) Ensure in manifest, package attribute is set to the above package[i.e com.compname.proj.views].
3) In manifest, under all activity tag, make sure android:name attribute has values matching to below pattern:
android:name=".<your activity class name>"
Ex: android:name=".SomeActivity"
My point is not to use package name + activity class name for manifest activity declaration.

Rare Android Unable to Instantiate Application Exception

I'm seeing the following exception under Crashes in the dev console from time to time.
Whats puzzling about it is that google maps shows up in the call stack as if its calling or creating my app class - very confusing. Whats further weird is the "MyApp-2.apk" in the call stack - where it appends the "-2".
I do include the android.maps.jar file in the libs.
I would like to know how to recreate this if possible and how to prevent this from happening?

Manifest Application Tag:
<application
android:name=".MyApp"
android:hardwareAccelerated="true"
android:icon="#drawable/app_icon"

I'm using these JARS: android-support-v4-r2-googlemaps.jar + android-support-v4.jar
The prime reason why a Class within your application would be present on your test devices but missing at runtime on some others would be if your class has a dependency on some external feature which is missing on those devices. For example, if you used some Google API which is not part of AOSP and so missing on a plain AOSP build, or a vendor build which does not license these, then your class will be pruned at install time as its dependencies cannot be resolved.
A common reason for your app finding its way into such circumstances might be someone running an inconsistently assembled "custom ROM" on their device.

Facebook Unity Sdk v5.0.3 crashes in Landscape mode when trying to login - Android

The game crashes when I click at login button as the game is in landscape mode. If I use portrait mode, everything works fine and correctly.
I got the following stack trace from bugsense when I got the crash.

If anyone of you has implemented this in landscape mode and is not getting a crash while logging in, do let me know.
yes, this is a bug, we are working on proper fix right now.
Meanwhile you can edit your android manifest in Plugins/Android and add android:configChanges so that FBUnityLoginActivity isn't destroyed when orientation/whatever changes:
<activity
android:name="com.facebook.unity.FBUnityLoginActivity"
android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen"
android:theme="#android:style/Theme.Translucent.NoTitleBar.Fullscreen">
</activity>
you may also want to remove "Translucent" from activity style.
I confirm that the change in the manifest file fixed the crash for me also. As additional info: the location of manifest the file was in Assets\Plugins\Android and the name was AndroidManifest.xml. I tested the fix on Sony Xperia M.

What could be causing a ClassNotFoundException?

So I've been working on an app lately which runs fine on most devices. However, sometimes the app crashes at start up with the following error:

I get that this is because it can't find the class called MainPager. But how is that even possible? I mean, the class should be there.. I put it there myself :) . Why on earth is it not finding it?
EDIT: I think the cause may be that in my manifest I have android:package="com.mypackage.app" defined, but that my launch activity is in the package com.mypackage.app.activities. Currently testing this theory. Still weird that it only happens on some devices, though.
This solution won't work, since I then can't update the APK in Google Play (has to be the same package name in the manifest).
Since ADT update to revision 22 (May 2013) you have to check "Android Private Libraries" check box in Project -> Properties -> Java Build Path -> Order and Export in Eclipse for your older projects to get rid of this exception ...
in the manifest you add Activity name like this
android:name=".activities.MainPager"
because you have given package name
android:package="com.mypackage.app"
Now I am using ART runtime on Nexus 5, and I am getting ClassNotFound for some apps.
You can safely ignore those if that's the case for your users.

Android Crash, java.lang.IllegalArgumentException: Window type can not be changed after the window is added

I am pretty sure I never use WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG as referenced in other postings. I do however, have a window that switches between WindowManager.LayoutParams.TYPE_PHONE and WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY. Which seems like it could be the error. I would prefer not changing this as it would require me to have two windows instead of just one. Thanks in advance!
check AndroidManifest.xml
<uses-sdk //************
android:targetSdkVersion="X"/>
X must be less than 14 Or remove this attribute.
good luck guy.

Error When creating an Application class in Android

I followed the advice given on the internet regarding working with Application classes in android.
I also added a field "android:name=.Session" to my Application object in the manifest.
The application is called "Session".
What do you think is the error? This is happening even before the my App starts.
This is the error stack:

Make sure your Session class is public, is not static, and does not have a default constructor.
public class Session extends Application {}
In the Manifest application tag, make sure you include the fully-qualified class name of your custom Application object:
<application
android:name="com.mycompany.myapp.Session"
.... />
The Android docs do say the class name must be fully qualified:
http://developer.android.com/guide/topics/manifest/application-element.html#nm
(This is not the case for Activity class names that are included in the activity tag of the Manifest. Those can be relative, preceded with a '.').
My solution was to delete the whole project from Eclipse and load it again from SVN. Now it works
