Android UI operations are not thread-safe, and only the main thread can operate the UI. At the same time, the main thread has a certain time limit on UI operations (up to 5 seconds ). To perform some time-consuming operations (such as downloading and opening large files), Android provides some column mechanisms. The articles in the "android basics 02-thread secur

difference in the composition of the object to parcel. With the parcel class and parcelable interface class, it is easier to pass objects like taskinfo. We can enable our taskinfo class to implement the parcelable function, so that all the generated objects will be transmitted at the underlying layer through the parcel object. The taskinfo class we defined earlier will be changed to the following: package org.lianlab.services;import android.os.Parcel;import android.os.Parcelable; public class

For example, the orientation at the to

Four storage methods for Android data: SharedPreferences, SQLite, Content Provider, and File (2) -- SQLite and androidsqlite SQLite is a lightweight database designed for embedded devices. It has only five data types: NULL: NULL INTEGER: INTEGER REAL: Floating Point Number TEXT: String BLOB: Big Data In SQLite, the BOOLEAN and DATE types are not specifically designed, because the BOOLEAN type can replace tr

Android Network Programming (2) HttpClient and HttpURLConnectionPreface In the previous article, we learned about the principles of the HTTP protocol. In this article, we will talk about HttpClient of Apache and HttpURLConnection of Java. These two types are commonly used in the request network. Both our encapsulated network request classes and third-party network request frameworks cannot be separated from

Android source code "application interface" Analysis 2 (PackageManager and PackageManagerService ): I. PackageManager: In the previous article, we usedPackageManager'sGetPackageSizeInfo function to obtain detailed information about the application.PackageManagerTo find out. 1. PackageManager class: It is an abstract class. We only list several functions to be discussed: Definition: publicAbstractClassPack

two simple rules for the android single-thread mode: 1. Do not block the UI thread; 2. do not access the android UI toolkit from outside the UI thread. Worker thread Because of the single-thread mode described above, it is vital that your application UI response does not block the UI thread. If you are not performing instantaneous operations, you should use a se

I 've been a little busy recently. I have to go to work tomorrow. I'm so angry. I am only free to post these two articles ··· The last time I talked about an idea, I first got the UI out. Android provides several data storage methods: 1, shared preferences 2, SQLite Database It is good to use sharedpreference for some simple small functions. Next we will implement a sign-in function. Let's take a look a

;} Compared with previous articles, you will find that there are two changes: one is that the getcount () method returns the maximum integer value instead of the number of images; The other part is imageview. setimageresource (image [position % image. Length]); The gallery component is displayed to the last image, and the position parameter value is exactly getcount ()-1. To achieve a loop, a large number must be returned, that is, the click can always go down, and the remainder of the position
