In QuizActivity.java, add a TAG constant to QuizActivity: Listing 3.1 Adding TAG constant ( QuizActivity. This makes it easy to determine the source of a particular message. The first string is typically a TAG constant with the class name as its value. Retrofit is a very powerful library that can make the most problematic API easy to use. (There is more about the Log levels in the final section of this chapter.) The first parameter identifies the source of the message, and the second is the contents of the message. Intent intentnew Intent (Intent.ACTIONVIEW) tData (Uri.parse (' startActivity (intent) For Example: In the below images, no component is specified, instead, an action is performed i.e. Retrofit 2 is the type-safe HTTP client, built by Square Inc for Java and Kotlin applications that simplify authenticating and interacting with REST APIs and sending network requests with OkHttp. The d stands for “debug” and refers to the level of the log message. Here is the one that you will use most often in this book: public static int d(String tag, String msg) To create a deep link to your app’s content you first have to create an intent filter.

Android Pass Object Via Intent Between Activity Example Overview. It is not difficult, you just need to make your custom class either implements the java.io.Serializable or android.os.Parcelable interface.

Now that you understand the parts of a deep link, it’s time to create one for your app. This article will tell you how to pass custom-type objects via intent between two android activities. Log has several methods for logging messages. code: The query parameter you can extract from intents in your destination. In Android, the class sends log messages to a shared system-level log. Each implementation will simply log a message informing you that the method has been called. In this section, you are going to override lifecycle methods to eavesdrop on QuizActivity’s lifecycle. You override them in your activity subclasses, and Android calls them at the appropriate time. It is important to understand that you never call onCreate(.) or any of the other Activity lifecycle methods yourself. Setting listeners on widgets to handle user interaction Inflating widgets and putting them on screen (in the call to ( setContentView(int))

Typically, an activity overrides onCreate(.) to prepare the specifics of its user interface: It has a simple UI, MainUnityActivity, which extends OverrideUnityActivity, and is prepared to start MainUnityActivity with an Intent 2.

The OS calls this method after the activity instance is created but before it is put on screen. You are already acquainted with one of these methods – onCreate(Bundle). You can extract action, extra input data from the intent input parameter. Subclasses of Activity can take advantage of the methods named in Figure 3.1 to get work done at critical transitions in the activity’s lifecycle. Your custom intent service class must override the onHandleIntent(Intent intent) method, this method will be invoked when intent service is called.
