Difference between Versioncode and Versionname ?
android:versionCode
An internal version number. This number is used only to determine whether one version is more recent than another, with higher numbers indicating more recent versions. This is not the version number shown to users; that number is set by the versionName attribute. The value must be set as an integer, such as "100". You can define it however you want, as long as each successive version has a higher number. [...]
android:versionName
The version number shown to users. This attribute can be set as a raw string or as a reference to a string resource. The string has no other purpose than to be displayed to users. The versionCode attribute holds the significant version number used internally.

What is the difference between Activity and Fragment in Android ?
fragment is a part of an activity, which contributes its own UI to that activity. Fragment can be thought like a sub activity. Where as the complete screen with which user interacts is called as activity. An activity can contain multiple fragments.Fragments are mostly a sub part of an activity.
An activity may contain 0 or multiple number of fragments based on the screen size. A fragment can be reused in multiple activities, so it acts like a reusable component in activities.
A fragment can't exist independently. It should be always part of an activity. Where as activity can exist with out any fragment in it.

What is the difference between getPreferences and getSharedPreferences in Android ?
getPreferences(0) - will open or create a preference file with out giving a name specifically. By default preference file name will be the current Activity name. if some one knows this, any once can access getPreference() file using that activity name. getSharedPreferences("name",0) - will open or create a preference file with the given name. If you want to create a preference file with a specific name then use this function. If you want multiple preference files for you activity, then also you can use this function. Note: preferences file will be with .xml extension stored in data/data/preferences folder.

What is the Purpose of the ContentProvider class ?
If you want to share the data of one application with the application then use content provider.
Note: We can start an Activity, a service, and a broadcast receiver by using intents.
But you can't start or communicate with a content provider by using intents.
If you want to communicate with content provider then you have to use content resolver.
1.content provider, and resolver will handle IPC(Inter process communication) mechanism when sharing data between
2 applications. 2.content provider has the capability to handle multiple threads, when queries are coming from multiple resolvers.

Is it Possible to Have Multiple Actions in an intent-filter ?
intent-filters can have 0 - n number of actions, but if that component has only one intent-filter with 0 actions, then that component can be triggered using only explicit intents. a given intent-filter can have more than one action because, a given component can do more than one action. EG: notepad can perform two actions ACTION_VIEW & ACTION_EDIT on an existing note pad file.

What is the Difference Between Service and Intentservice in Android ?
i Intentservice by default will create one separate thread to handle the service functionality.
All the startservice requests for intentservice will be routed to that thread.
ii. Where as service by default runs in main thread. All the startservice requests will be routed to main thread by default.
iii. While implementing a service, programmer has to implement onCreate(), onStartCommand(), and onDestroy() methods.
iv. Where as while implementing IntentService programmer has to implement only onHandleIntent().
v. After starting IntentService, it will be automatically closed if there are no pending startService requests.
vi. Where as for normal service programmer has to stop the service explicitly either by using stopSelf() or stopService() methods.
vii. Don't try to touch UI from IntentService's onHandleIntent() method directly, as that function runs in a separate thread. (Not in main thread).

What are Adapters and When and How are they used ?
It is tough to develop an Android app without using an adapter somewhere because they are so important.
Where do adapters fit in? They bridge the Model and View (e.g. AdapterViews such as ListViews, GridViews, Spinners and ViewPagers) with underlying data. They provide access to data items and are responsible for Creating a view for each item in the data set.
Android doesn’t adopt the MVC pattern per se. You define the Model that works for you. Android helps you layout and render views, and you customize Android’s Activities and Fragments that typically act as Controllers.
Novice developers might try to get away with using simple helper adapters like ArrayAdapter, SimpleAdapter and SimpleCursorAdapter when possible, but these are usually too limiting for some of the more complex views typically required by todays apps. Master developers will write adapters that extend BaseAdapter directly, because it is more powerful and flexible than the subclass helpers mentioned above.

What is an URI ?
Android uses URI strings both for requesting data (e.g., a list of contacts) and for requesting actions (e.g., opening a Web page in a browser). Both are valid URI strings, but have different values. All requests for data must start with the string “content://”. Action strings are valid URIs that can be handled appropriately by applications on the device; for example, a URI starting with “http://” will be handled by the browser.

What is AsyncTask ?
AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.An asynchronous task is defined by a computation that runs on a background thread and whose result is published on the UI thread. An asynchronous task is defined by 3 generic types, called Params, Progress and Result, and 4 steps, called onPreExecute, doInBackground, onProgressUpdate and onPostExecute.

What are the different Storage Methods in Android ?
Android provides many options for storage of persistent data. It provides the solution according to your need. The storages which have been provided in Android are as follows:
Shared Preferences: Store private primitive data in key value pairs
Internal Storage: Store private data on the device memory.
External Storage: Store public data on the shared external storage.
SQLite Databases: Store structured data in a private database.
Network Connection: Store data on the web with your own network server.

What is a Sticky Intent ?
Intent is basically an abstract description of an operation that has to be performed for communication. Sticky Intent is also a type of intent which allows the communication between a function and a service.
sendStickyBroadcast() performs a sendBroadcast (Intent) known as sticky, i.e. the Intent you are sending stays around after the broadcast is complete, so that others can quickly retrieve that data through the return value of registerReceiver (BroadcastReceiver, IntentFilter). In all other ways, this behaves the same as sendBroadcast(Intent).

What is a Broadcast Receivers ?
A broadcast receiver is a component that does nothing but receive and react to broadcast announcements.
For example, announcements that the timezone has changed, that the battery is low or that the user changed a language preference.
All receivers extend the BroadcastReceiver base class.
Broadcast receivers do not display a user interface. However, they may start an activity in response to the information they receive, or they may use the NotificationManager to alert the user like(flashing the backlight, vibrating the device, playing a sound)

What is an Intent Filter ?
Activities and intent receivers include one or more filters in their manifest to describe what kinds of intents or messages they can handle or want to receive. An intent filter lists a set of requirements, such as data type, action requested, and URI format, that the Intent or message must fulfill. For Activities, Android searches for the Activity with the most closely matching valid match between the Intent and the activity filter. For messages, Android will forward a message to all receivers with matching intent filters.

What is the Difference Between Service and Thread ?
Service is like an Activity but has no interface. Probably if you want to fetch the weather for example you wolud not create a blank activity for it, for this you will use a Service. It is also known as Background Service because it performs tasks in background.
A Thread is a concurrent unit of execution. You need to know that you cannot update UI from a Thread. You need to use a Handler for this.

What is a Toast Notification ?
A toast notification is a message that pops up on the surface of the window. It only fills the amount of space required for the message and the users current activity remains visible and interactive. The notification automatically fades in and out, and does not accept interaction events.

What is Android Runtime ?
Android includes a set of core libraries that provides most of the functionality available in the core libraries of the Java programming language. Every Android application runs in its own process, with its own instance of the Dalvik virtual machine. Dalvik has been written so that a device can run multiple VMs efficiently. The Dalvik VM executes files in the Dalvik Executable (.dex) format which is optimized for minimal memory footprint. The VM is register-based, and runs classes compiled by a Java language compiler that have been transformed into the .dex format by the included dx tool.

What is Dalvik Virtual Machine ?
The name of Android virtual machine. The Dalvik VM is an interpreter-only virtual machine that executes files in the Dalvik Executable (.dex) format, a format that is optimized for efficient storage and memory-mappable execution. The virtual machine is register-based, and it can run classes compiled by a Java language compiler that have been transformed into its native format using the included dx tool. The VM runs on top of Posix-compliant operating systems, which it relies on for underlying functionality (such as threading and low level memory management). The Dalvik core class library is intended to provide a familiar development base for those used to programming with Java Standard Edition, but it is geared specifically to the needs of a small mobile device.

What is the Difference Between a File, a Class and an Activity in Android ?
File: It is a block of arbitrary information, or resource for storing information. It can be of any type.
Class: Its a compiled form of .Java file . Android finally used this .class files to produce an executable apk.
Activity: An activity is the equivalent of a Frame/Window in GUI toolkits. It is not a file or a file type it is just a class that can be extended in Android for loading UI elements on view.

<activity android:name=".MyTestActivity"></activity>
Activity is to be declared in the manifest file. For example:
<activity android:name=".MyTestActivity"></activity>
How Will You Pass Data to Sub-Activities ?
We can use Bundles to pass data to sub-activities. There are like HashMaps that and take trivial data types. These Bundles transport information from one Activity to another.
Bundle b = new Bundle();
b.putString("EMAIL", "abc@xyz.com");
i.putExtras(b); // where i is the intent

How Can Your Application Perform Actions that are Provided by other Application e.g. Sending Email ?
Intents are created to define an action that we want to perform and the launches the appropriate activity from another application.
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, recipientArray);
startActivity(intent);
