My app freezes crashes when it's supposed to go to the next activity

I don't know why the app crashes whenever it's supposed to go to the next Activity. I made a practice app that works as it should when using the same format. I uploaded the files to gist.github.
The error is
1216-1216/com.example.chiozokamalu.newfreshstart E/AndroidRuntime﹕ FATAL EXCEPTION: main

The questions array at line no. 164 is going out of bound that means questionIndex is greater than the total length of the questions array. So you should add a check on the length before extracting value from the array.
You have added the check but after that you incremented the value so either you modify the if condition to if (questionIndex < questions.length -1)
or modify the questionIndex variable before the if condition
You are getting problem because you haven't initiated resultView9 that is why it is null and giving nullpointer, just initiatlise it as you done with other and everything is fine. You have initialised the resultView8 twice just add resultview9 over there

NoClassFoundError MultipartEntity error in android

I am not able to figure this problem out.I added the following jars.
httpClient-4.2.5.jar
httpcore-4.2.4.jar
httpmime-4.2.5.jar
I added these jar through Add External JARs option in Build Paths and then added them manually in the libs folder of my eclipse project still it gives me the following error while debugging the following line.
MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
Actually I am trying to upload multiple images to my php server using this.

Found out myself.The problem was that I didn't include the READ_EXTERNAL_STORAGE permission.
I added the following line in my manifest and it worked.
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

ArcGIS - Unsatisfied link error find library returned null - Hello World sample app

This is my first time into the ArcGIS but not the first time for Android. I am an Android developer. For one of our recent projects, i am exploring the ArcGIS modules/samples. I did the following steps:
Installed Eclipse JUNO (latest) - Since my previous version got corrupted, had to replace the system.
Downloaded ArcGIS runtime SDK for Android 10.1.1.
Installed the ArcGIS plugin from the downloaded zip file obtained from step 2.
Restarted Eclipse/System.
Now to explore the basic "Hello World" ArcGIS app, i did the following steps.
File - New - Project - In the new window - selected the "ArcGIS for Android" option.
Out of the 2 options i selected "ArcGIS samples for Android". This option opened another window to fetch the samples from local or online.
I selected "LOCAL".
Under "Maps" section, i selected the "Hello World" sample project.
Now the Hello World project is in my workspace.
Cleaned and build the project. All errors gone.
Run the project.
I am obtaining the following error log:

Later i followed the ArcGIS forums and came across many links for example
http://forums.arcgis.com/threads/484...-returned-null
http://forums.arcgis.com/threads/850...ello-World-run
but alas the error was never cleared.
I encountered a similar problem with one of my Android projects. It had the libs folder with .so files for armeabi and armeabi-v7a. I converted the project into a library and used it one of my another project. Since it was a small project i didn't needed to explore the converted library project. This is due to the referencing of the .so files or library files related to the Eclipse updates. I am still unsure how to configure the .so files into the build path so that there is no "Unsatisfied link" error.
Please see the screenshot attached for the Build Path of this project.

Like Google maps , arc GIS also won't work in Emulator , to run your
app in Real device it should work

pull to refresh example, error

I'm trying to add the "pull to refresh" widget to my code, I'm just using this example:
https://github.com/johannilsson/android-pulltorefresh
So, I create the pullToRefresh package, generate a jar file with eclipse and import it in other package, I got this error:

what I see more important:-
06-26 10:55:05.482: E/AndroidRuntime(508): at com.pull.widget.pullToRefresh.init(pullToRefresh.java:92)
Is this line:
mRefreshViewText = (TextView) mRefreshView.findViewById(R.id.pull_to_refresh_text);
in "pullToRefresh.java" in the package created.
From the package, what could it be happening??
Thanks in advance

please can anyone explain this error in logcat

The solution to this problem is to create a folder named "libs" in the project directory and copying all the external jar files there.

I think what you face is that your code compiles , but # run time it crashes . How do i solve this , create a libs folder in your project inside eclipse(if its not exist) and add the jar file that contains the org.mythrii.email.Mail class inside the libs folder , Then run you app .
