I have recently had to update my SDK and ADT and since then I have been having loads of trouble with existing applications. My problem is that with one of my applications I am getting the following error:

This is occurring when I am trying to load up a fragment activity that contains maps v2.
This is confusing to me because in another application that I have, there is maps v2 code inside this app and this app has no problems with it. I have checked all the settings and made sure that everything matches, but I am still getting this crash.
Can someone please help.
EDIT
In changing the project and placing the google-play-services-lib.jar file in the libs folder I am now getting the following error

This is now exactly the same as my other project that is working, I am really confused at why this one isn't working
You should not place the jar in libs folder.
You should google play services library project in your android project.
Import library project into workspace and eclipse.
Right click on your android project. goto properties. Choose android. click add. Browse the library project and add the same.
Now if you have updated adt to rev 22.
java.lang.ClassNotFoundException after changing nothing in the project but upgrading eclipse android sdk
to check if its a library project. right click on your google play services library goto properties choose android. You will see Is Library check box checked
After adding it looks similar to the one below
I upgrate SDK and ADT(ver22) yesterday just like you .
And have same error
I try this and it's work ...

I recently moved to MoPub and it all appears to be working well except for I have started getting this exception saying that com.millennialmedia.android.VideoPlayer can not be found. I looked and it isn't on the Millennial jar (I just got the latest from their site). Also my AndroidManifest mentions that class and Android Studio also says it can't be found.
This is what I have there:
<activity android:name="com.millennialmedia.android.MMActivity" android:theme="#android:style/Theme.Translucent.NoTitleBar" android:configChanges="keyboardHidden|orientation|keyboard" />
<activity android:name="com.millennialmedia.android.VideoPlayer" android:configChanges="keyboardHidden|orientation|keyboard" />
On Android Studio the VideoPlayer part is red.
This is the exception I got:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{mypackage/com.millennialmedia.android.VideoPlayer}: java.lang.ClassNotFoundException: Didn't find class "com.millennialmedia.android.VideoPlayer" on path: /data/app/mypackage-1.apk

Looking at the latest Millennial Media documentation, it looks like
com.millennialmedia.android.VideoPlayer
isn't included. This may be an update that needs to be made.

I am working on a simple android application which has a ViewPager with swiping images. I have static application containing 12 images. When I swipe, the app is getting crashed after the fourth image.
How can I understand the stacktrace and solve this problem?

It seems you are using image with very large size that the device can not handle. Try using some smaller sizes
ViewPager adapter loads all your images at a time that's why you got the error. So what are the actual reason:
1. Your image size is very large
2. You did not use image resources properly. Try to put your different size image in different folder like ldpi, hdpi, xdpi folder.
Try to use the above tricks.
If you still get error, you can follow this:
Change the FragmentPagerAdapter to a FragmentStatePagerAdapter. The reason for this is that the FragmentPagerAdapter will keep all the views that it loads into memory forever. Where the FragmentStatePagerAdapter disposes of views that fall outside the current and traversable views.
Override the adapter method getItemPosition (shown below). When we call mAdapter.notifyDataSetChanged(); the ViewPager interrogates the adapter to determine what has changed in terms of positioning. We use this method to say that everything has changed so reprocess all your view positioning.
Actual answer is here: Remove Fragment Page from ViewPager in Android
I did change the FragmentPagerAdapter to a FragmentStatePagerAdapter. However the swiping motion is quite sluggish. Seems like it solved the problem for the time being.
/**
* The {#link android.support.v4.view.PagerAdapter} that will provide
* fragments for each of the sections. We use a
* {#link android.support.v4.app.FragmentPagerAdapter} derivative, which
* will keep every loaded fragment in memory. If this becomes too memory
* intensive, it may be best to switch to a
* {#link android.support.v4.app.FragmentStatePagerAdapter}.
*/
The detail tutorial is available here http://blog.kerul.net/2013/09/adding-xml-layout-in-swipe-views.html
Currently project target sdk is google api level 14 and it runs well. If I changed target sdk to google api level 16 in android manifest file and run the project then it shows message unfortunately, app has stopped. Again if I change it back to level 14 then it runs.Can anyone tell me the what can be the reason?

You have to add the following line to your AndroidManifest.xml file:
<uses-permission android:name="android.permission.WRITE_CALL_LOG"/>
If you are just reading this log, change the line to:
<uses-permission android:name="android.permission.READ_CALL_LOG"/>
Put this line above of your <application> tag. Or, if you have other permission entries as well, where those others are.
Those permissions were added with the API-Level 16. See for example the documentation to the value READ_CALL_LOG.
in my android application it does not seem to let me use the accelerometer. when i call it in a statement the application crashes. the statement that seems to be causing the crash is:
SensorManager sensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
The application is simple as is only calls the accelerometer and runs when this statement is absent, the above statment is called before the onCreate method and the log cat is below

from the logcat i cannot figure out the cause of this problem when this statement worked in a different programme.
Thats a double negative? lol Cut the code where ure calling the system service and paste inside your onCreate
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//PLACE YOUR ACCEL CODE IN HERE
}
You have to grab the SensorManager after onCreate is called.
"System services not available to Activities before onCreate()"
I've tried this for 2 hours now and I dont seem to get it to work. I want to build a framework for my application, in another project. First of I'm just trying to reach a class from that other project. The code compiles but fails at runtime, at the line where i instantiate an object from a class from the framework.

I know there is a lot on this topic, but I've have searched for hours without any posts solving this problem. Most of the topics are how to reference to another project. But since my code is compiling it should be referenced?
And does both projects needs to be Android projects? Should the framework project be a library? Thanks for any help!
if the library project is an android project , you need to make it a library one by choosing it from the project properties , and then to reference it via the same place but on the project that uses it.
don't forget that there are some rules when you use a library project . see my post here for more information.
if the library project is java , its exactly as using other java projects.
This is a long shot, but it worked for me (having also spent hours on this, after reading all the same posts you did...)
If you are confident that you have correctly configured the project references, this could be a result of a silent build failure.
In my case, the problem arose due to incompatibilities between the build environments for my two projects. In Project "A", which was pure Java, the following line compiled without error in Project A's build environment:
if ((int) d.get("good")) == 0) {....
It turns out that this was not legal in the (Android) Project "B", which required an object cast:
if ((Integer) d.get("good")) == 0) {....
However, the only indication that I got of the error was the same as what you experienced, a "VFY: Unable to resolve..." error.
I found the error in a painful way: By copying the code from Project "A" into Project "B," finding the errors, and fixing them in Project "A." There is probably a more intelligent way than mine to find such incompatibilities, such as by tweaking the settings in both projects to match exactly.
