019: Effective Java for Android developers : Item 4 Oct 15, 2015

Show notes

Singer and Android developer Donn Felker explores Joshua Bloch's fourth Item: Enforce noninstantiability with a private constructor.

Stay tuned, cause we got more of these quick ones coming.

Effective Java (2nd Edition) - Joshua Bloch

Enforce noninstantiability with a private constructor.

Examples where you don't want class to be instantiated

class that groups static methods and static fields (Util like classes think java.lang.Math/java.util.Arrays)
class that groups static methods (including factory methods) for objects implementing specific interfaces (think java.util.Collections)
class that group methods on a final class (vs. extending the class)

Considerations

Makes no sense to instantiate such "Util" classes
Private constructors prevent instantiation
Important side effect: prevents subclassing

018: Effective Java for Android developers : Item 3 Oct 08, 2015

Show notes

In this mini Fragment, we introduce Joshua's third Item: Enforce the Singleton property with a private constructor or an enum type.

Stay tuned for more items from our "Effective Java for Android developers" Fragment series.

Show Notes

Effective Java (2nd Edition) - Joshua Bloch

Enforce the Singleton property with a private constructor or an enum type

Approaches

Create a public static final INSTANCE variable and privatize constructor
Same as 1 but privatize variable and expose access with provide factory method getInstance
Single element Enums

Considerations

First two approaches are open to Serialization attacks (deserializing creates new instance)
To protect from those declare the fields transient + provide readResolve method
Enums are concise, provide free serialization and ironclad Singleton guarantees and are functionally equivalent to first approach

Supplemental reading (for the diligent ones that follow shownotes)

Effective Java (2nd Edition) - Joshua Bloch

Consider a builder when faced with many constructor parameters

Patterns available for constructing object with parameters:

Telescoping Constructor Pattern - Provideconstructor with only required parameters, another with a single optional param, a third with 2 optional params... and so on.
- Advantage: Works well for small number of parameters
- Disadvantage: Does NOT scale well
JavaBeans Pattern - Callparameterless constructor to create the object; then call setter methods to set required parameter and each optional param of interest.
- Advantage: Scales well, easy (but wordy) to read resulting code
- Disadvantage: Allows inconsistency (if all required params not called); impossible to make classes immutable if using this pattern.
Builder pattern - winner!
- Advantage: Simulates named optional parameters; allows immutable objects to be constructed; flexible
- Disadvantage: more ceremony to actually construct the Builder Class and finally use.

Example usage from Android source:

AlertDialog Builder [androidxref.com]

Tip:

Use IntelliJ to generate your Builders easily

014: Effective Java for Android developers : Item 1 Aug 10, 2015

Show notes

We've mentioned the book "Effective Java" by Joshua Bloch quite a few times on previous episodes. At this point, everyone knows they should have read this book (quadruple times). But it's a dense read and everyone could use a reading buddy. Also, what does Effective Java look like through the eyes of an Android developer?

In this second installment of our Fragment (a.k.a mini-episode), we thought we'll do our listeners a favor and help with that reading. We introduce the very first of these venerable "Items": Consider providing static factory methods instead of constructors.

Stay tuned for more items from our "Effective Java for Android developers" Fragment series.

Show Notes:

Effective Java (2nd Edition) - Joshua Bloch

Consider providing static factory methods instead of constructors

static factory method makeText for Toast class [androidxref.com]
ObjectAnimator [androidxref.com]:
- .ofInt [androidxref.com]
- .ofArgb [androidxref.com]
- .ofFloat [androidxref.com]

Advantages:

You can control the name and thus give it much more meaningful names
You are not required to create a "new" object each time they are invoked
You can even return an object that's a subtype of the return type (unlike constructors which only return class type)

e.g. Java Collections framework [grepcode.com]

Disadvantages:

Classes without public or protected constructors cannot be subclassed
Static factory methods are not readily distinguishable from other static methods

Takeaways

"Consider" using static factory methods (not always)
Use newInstance when creating Fragments [androiddesignpatterns.com]
Use newIntent static factory method for creating intents inside the target activity.

012: Continous Integration and Collective Code Ownership Jul 21, 2015

Show notes

In this episode we're trying something new. Everyone has requested more episodes of the podcast. In short, everyone wants a weekly show. So this week, we're introducing what we call a mini-episode ... or as we like to call them a "Fragment". Fragment episodes will be shorter in length but still packed with goodness. They will range from ~7-25 minutes in length and will showcase either Kaushik, myself (Donn) or both of us.

In the first "Fragment" installment we're going to talk about Continuous Integration (CI) and Collective Code Ownership (CCO). Donn talks about what CI is, why its important and how it benefits you and your team. He then dives right into CCO and how it can be facilitated through testing.

We hope you enjoy these new mini-episodes ... aptly named ... Fragments. :)

011: The Fowler Road to a Clean Architecture Jul 14, 2015

Show notes

In this episode - Donn and Kaushik dive into a topic that is very near and dear their hearts - application architecture. They talk about how Martin Fowler has inspired a lot of their architectural decisions and how they're moving towards defining what a clean architecture means to them and other developers. They talk about Model View Presenter, Model View Controller and many other topics that surround these two common patterns. Take a listen and go for the ride on architecture train ... all aboard!
