Android: Multiple Sceen layout API

I just want to make sure I'm understanding the method to setup for multiple screen.
I want to make the app runnable from API 8-21.
So far, I implemented smallest-width to differentiate the multiple screen. Everything works perfectly in the emulator when I use API 17, but crashes when i use API 8. I then realized that smallest-width only works for API 13 and above.
So now, I think my next step is to just create layout-small, layout-normal, etc. and adjust it for them.
Is this the correct way to tackle the problem?
Edit***********
Here's the logcat from the error filter, let me know if I need to post the other:

Also would like to add that my default layout folder is empty. Under API8, it seems like it's trying to load off that folder, instead of layout-sw-320dpi, which is probably the reason for the crash. I tested on API17+API21 and it loads off the layout-sw-320dpi just fine.
Edit2:
Seems to only work on API16+.
Edit3:
My manifest's sdk:
android:minSdkVersion="8"
android:targetSdkVersion="21"

No , problem is caused by due to your java class not by your xml files what I can assume from this point.

Google Maps Android API v2 crashes with NoClassDefFound Error

I am trying to implement the most basic example of google maps android api v2 example.
But it crashes with the error:java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable.
I have set up the google api and have looked at stackoverflow posts like:
-https://stackoverflow.com/questions/14252879/google-maps-android-api-v2-tutorials,
-Google map android API V2 crashed
and
-https://stackoverflow.com/questions/13796822/google-map-android-api-v2-application-crashes
but their problems are slightly different than mine.
Can you please point me to the right direction? I am using android 2.2 and would like to use the new Maps to make use of fragments in my app; so that I can get some functionality like apple's uinavigation to push new views in a pop up activity.
Thanks.
Thank you,how did you get to the png you are showing in the attachment?The google play service is shown as a referenced library in my package explorer; I did add it; this is my logcat:

Please check if the "libs" folder containing the "android-support-v4.jar" exists in your project. Because you are using Android 2.2, you must have "libs " folder in your project root directory. If you have not that, just copy that jar file into your "libs" folder .
"android-support-v4.jar" is located in "/extras/android/compatibility/v4/android-support-v4.jar" under your drectory.
And before running your project, you must set your project Build target to "Google APIs", not Android x.x. version : Select your project and click Project > Properties > Project Build Target in Eclipse and select any "Google APIs ", and then run your project on your phone. If you use the emulator, also MUST set the AVD of the emulator to the any "Google APIs ".
Once more, you don't need to create the new Google Maps API key in order to test your project, Just use the default provided API key, which is shown as "Key for browser apps (with referers) "in your Google APIs Console.

Use Android SDK Manager download "google play services"
import it into your workspace (path: android-sdk root/extras/google/google_play_service/libproject/google-play-service_lib)
project Properties -> android -> Library add google-play-service_lib
Build path -> Order and Export check Android private libraries

I solved this error by checking "Copy projects into workspace" while importing the Google Play Services lib.

Null Pointer Exception in First Android App

I am trying to write my first Android app, and I'm having trouble. I wrote a simple Java program to find the factors of a number provided by the user, and I'd like to port it over to Java. I have an XML file for the interface, which seemed to run OK until I added the first Java class. Now it won't run, and log.cat says that there's a null pointer exception. So far, I only have stubs, but it seems like it should run OK with what I've done to this point. I'm including the log.cat text, but I'm too new it this to make much sense out of it.
There may be more than one problem. After adding the Java file I began to get run-time errors right away, but I don't think they were null pointer exceptions. I think that started when I made changes to fix what was already causing problems.
Any help is appreciated.
Here is the Java file:
import android.app.Activity; <br>
import android.os.Bundle; <br>
import android.widget.Button; <br>
import android.widget.EditText; <br>
import android.widget.TextView; <br>
public class AndroidFactoringActivity extends Activity {
// Instance Variables
EditText userNumber;
Button factorButton;
TextView resultsField;
int factorResults;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
factorButton = (Button) findViewById(R.id.factorButton);
userNumber = (EditText) findViewById(R.id.userNumber);
factorResults = 1;
resultsField.setText(String.valueOf(factorResults));
}
}
Here is main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<EditText
android:id="#+id/userNumber"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="number" >
<requestFocus />
</EditText>
<Button
android:id="#+id/factorButton"

resultsField.setText(String.valueOf(factorResults));
resultsField is null and you are trying to set value on null.
resultsField= (TextView ) findViewById(R.id.userNumber);
Get textview instance before setting value, otherwise resultsField will be null and all operations on null reference results in NullPointerException.

You got a null pointer because you didnt intialise the variable resultsField (you just declared it) .
As you used
userNumber = (EditText) findViewById(R.id.userNumber);
you must even initialise the reference resultsField.
This can be done using
resultsField= (TextView ) findViewById(R.id.resultsField);
in the onCreate() after the statement setContentView()

You need to initialize the userNumer and resultsFiled as follows
userNumber = (EditText) findViewById(R.id.userNumber);
resultsField= (TextView ) findViewById(R.id.resultsField);

Memory Error during frame animation in Android application

Hi im trying to set up a frame animation with a series of images as a background for my splash page in an android application at the moment there is no errors but when I run the application it quits unexpectedly. The first error which follows 10 garbage collections is E/dalvikvm-heap(276): 1234272-byte external allocation too large for this process. I have 17 images I am using for the frame animation each of them are 50k or less so I dont think that the image sizes can be the issue.
The java code I have implemented in my main activity is as follows:
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView frameanimation = (ImageView) findViewById(R.id.frame_animation);
AnimationDrawable frame_animation = (AnimationDrawable) frameanimation.getBackground();
frame_animation.setVisible(true, true);
frame_animation.start();
}
I then have this code implementing an image view within my XML Layout file:
<ImageView
android:id="#+id/frame_animation"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:src="#drawable/frame_animation"
android:background="#drawable/frame_animation"/>
and finally I have my animation drawable saved as 'frame_animation.xml' within my drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">

Any help is much appreciated, I just cannot figure out what is causing the problem.
Thanks

The images you are using might be too large for an animation. How large are they? In an animation, Android loads all of the images into memory and uncompresses them meaning that every pixel will take 4 bytes. So 50k would mean that your image is 111px x 111px. It seems from the error each frame is about 480 x 640, which is really large. Try using smaller images.

Im designing my first android application and keep coming up with the following error which is draining the life out of me and I do not understand it very well (Please find my Logcat (verbose), Java Code(this i played around with and this began to occur once started to work on my editButton and buttonUpdate bit. Does it have anything to do with the editStatus? I really think it may) and I have also put in my manifest file:

I have;
attempted to do adb kill-server and adb start-server and run it with an without an emulator as suggested in another post. Please be slightly understanding as my knowledge of eclipse and Java is pretty low and im learning.
Please help

As seen from this error:
java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.locator.demo/com.locator.demo.LocatorDemoActivity}:
java.lang.ClassCastException: android.widget.TextView
And this one:
Caused by: java.lang.ClassCastException: android.widget.TextView
You are trying to cast a TextView to EditText ( in this line: editStatus = (EditText)findViewById(R.id.edit_status);).
Go to locationstatus.xml, and change the TextView with the id edit_status to EditText.
