When we use a third-party framework, we often see xxx.bundle files. We find the file, show the package content, and see a lot of resource files: Pictures, configuration text, xib files ...What is a bundle file? A simple understanding is a resource file package. We organize many pictures, XIB and text files together and package them into a bundle file. facilitates referencing resources within packages in oth
Android uses bundle to pass objects through intent
In Android development, you sometimes need to pass objects between applications or between processes, and here's a detailed description of how intent uses bundle to pass objects.
The object being passed needs to be serialized first, and there are two ways to serialize the object:java.io.Serializable and Android.os.Parcelable
Serializable is used in Java,
Bundle's Understanding:
A container class that holds the map type of the string and parcelable type data, obtains the corresponding values of various types by holding the Data key (key), and must be obtained by key.
Usage of bundle:
Bundle is equivalent to the map class, is a mapping, with bundle binding data for easy data processing
It mainly acts on the data
Bundle may use the put *** () method to add various types of data. Intent can also add data through putextras (bundle), and then use startactivity () when you jump to the next activity, the data is uploaded to the next activity.
package com.intent;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import andro
There is often a need to encapsulate your own modules or open classes into static libraries for convenient calls.
However, when your module needs to use a large number of XIB, images, audio or other resource files, it cannot be added to the static library. In this case, some resource files need to be encapsulated into the. Bundle file. The encapsulated items should contain three types of files:
1: Open header files (including complete call notes)
2: T
The Android program is known to have a method named OnCreate in the activity. This method is called by the system when activity is created, and is the beginning of an activity life cycle. But one thing that is easily overlooked is the parameter savedinstancestate of the OnCreate method. Because this parameter is seldom used in general program development.The complete definition of the OnCreate method is as follows:public void OnCreate (Bundle savedins
There is no difference in nature between the two.Bundles are just a carrier of information that organizes internal content into key-value pairsIntent is responsible for the interaction between the activity itself with a bundle ofIntent.putextras (Bundle bundle) directly sets the Intent internal bundle as the
First, what is the library libraries are actually a way of sharing code, primarily for code reuse and source hiding, usually in dynamic and static libraries.Static Library: A full copy of the link is made to the executable file, and multiple copies are used multiple times.Dynamic Library: The link is not copied, the program is dynamically loaded into memory by the system, for program calls, the system is only loaded once, multiple programs shared, saving memory space.Ii. what is. A,.
In an application, data may need to be transferred when you jump to another Activity. In this case, Bundle objects may be used;
In MainActivity, there is an Intent that directs to BActivity,

There are three ways to develop the Android environment, namely Jdk+sdk+eclipse+adt, Jdk+adt-bundle, and Jdk+android Studio.
Do not use Jdk+sdk+eclipse+adt this way, not to say what is too complicated, because the Guo Jia network you know, open the SDK tool after the download is not. Android Studio is also not good, said the collection of large open environment. It still needs to be networked when it's installed.

By merging multiple files into a single final executable file, running this final composite file is equivalent to running multiple files before merging. This kind of procedure is used frequently in the Trojan horse program merging, you want to know how it uses the program to realize?
