FragmentStatePagerAdapter getItem not called

Using FragmentStatePagerAdapter instead of FragmentPagerAdapter might fix this problem. 

FragmentPagerAdapter stores the whole fragment in memory, and could increase a memory overhead if a large amount of fragments are used in ViewPager. But FragmentStatePagerAdapter only stores the savedInstanceState of fragments, and destroys all the fragments when they lose focus. 

Hence FragmentStatePagerAdapter should be used when we have to use dynamic fragments.

Eclipse Error : contains native libraries that will not run on the device

Few days back I wanted to try Crittercism's NDK library and ended up facing the following error in Eclipse after following exactly the same steps given on their site.

The library 'crittercism_v4_5_1_ndk.jar' contains native libraries that will not run on the device.

The following libraries were found:

- assets/armeabi-v7a/libcrittercism-ndk.so

This error could be avoided by the following Steps.

Eclipse Preference ->Android->Build->Un Check "Force error when external jars contain native libraries"

The problem started last week when I started receiving Cell Broadcast alerts non stop all day. My phone is Samsung Galaxy S2 and was running on latest version of Cynogenmod.

Message->Menu->Cell Broadcast

Even after doing so the problem did not go away. Finally after lot of searching I found a way to do this. Use Terminal Emulator and execute the following commands.

UI≠UX

Difference between UI and UX




The most common misconception we come across in the workplace, in client meetings or even in the Job listings is that the terms UI and UX are interchanged and used in the wrong context. Though both the terms look and spell alike there is a substantial difference in the overall objective and scope.

User Interface (UI) is a medium of communication between a person and a system. UI encompasses approaches and elements that allows the user to interact with the system. In other terms UI can be considered as the most powerful tool that designer use to bring out a great user experience.

On the other hand User Experience (UX) is:

• The overall experience


• A combination of various interface, UI being an important one among it.


• Thrives to address everything perceived by a person

A UI designer can only solve a part of the equation by creating tools such as images, icons, text but the user experience is much larger than that and is influenced by a multitude of things such as functional performance, color scheme, ease of use etc. Hence for an organization it is very important to understand the basic difference between the two roles and hiring the right candidate with proper skill set.


Last but not the least...

This is what happens when you let a developer play the role of UI/UX designer
