so on. For example, "*" means matching any class name but does not include the package delimiter, while "* *" matches any class name and includes any number of package delimiters. So the code we commented on above means the following: the first line: all methods that keep all classes under Com.ttdevs.proguard and sub-packages are not confused, and the second row keeps all methods and member variables of the class under Com.ttdevs.proguard and all the classes under the sub-package are not confus

View.setelevation () method in your code.Set the panning of a view using the View.settranslationz () method.The new Method Viewpropertyanimator.z () and Viewpropertyanimator.translationz () can make it easier for you to change the height of the view. For more information, see E mentor's Android app development video tutorial .You can also define these files in an XML file using the Statelistanimator method

This series of special training applies to: Beginner Android programmers, that is, j2se basics and Android beginners. J2se refers to mastering the Java syntax. It doesn't matter if the New syntaxes 1.5 and 1.6 are not fully mastered. Understand basic object-oriented ideas, write simple j2se programs, master basic debugging methods, and be familiar with swing.

the flag variable is 1, indicating that a connection was generated.When currentstate-historystae =-1, the state is connected to a break, at which time the flag variable is 0, indicating that a fracture has occurred.Create a function to get the Currentstae:public int getcurrentstate () {return this.manager.getWifiState () = = wifimanager.wifi_state_enabled? 1:0;}Next we modify Mythread's Run method as follows:@Overridepublic void Run () {if (historystate = =-1) {currentstate = Getcurrentstate ()

that the device can run the Android 4.4 system smoothly with just 512MB of memory. In addition, Google provides developers with memory usage analysis tools to help developers better monitor their applications and reduce RAM usage."512MB of Memory enough" such a message is really ecstatic, but we also do not be happy too early, after all, pretending not to be loaded with the use of not good is a different thing. Google says 512MB of memory is enough,

most are translated by Google's official documents. Because of the time problem, coupled with their own English is bad enough, the recent slow. However, such a down, plus some of their own code exercises, for the material design can be basically used. Unfortunately, most of the style is not backward compatible, had to wait 5. There are some big God in the Internet has been open source some open source components, we can take this curve to salvation, the next time in a special collation. This ar

, although the name is slightly different, but the bottom-up implementation still through the above four ways.1.Activity implements value transfer between two appsSuppose you have two apps APP1 and APP2, and you want to start APP2 in Activityb by clicking on a button in the Activitya in App1 or another control's click event. The steps are as follows:1. Exposing the ActivitybFor example, now that a loginactivity needs to be exposed, you can modify the

for animation: Z = elevation + Translationz Shading of views of different heightsSet evelation in the layout file android:elevation and use the method in your code View.setElevation() .Set the panning of a view using the View.settranslationz () method. New method viewpropertyanimator.z () and viewpropertyanimator.translationz () allows you to change the height of the view more easily. A lot of other information, see Viewpropertyanimat

() { super.oncreate (); System.out.println ("Service started"); } @Override public void OnDestroy () { Super.ondestroy (); System.out.println ("Service destory");} }　　AnotherappPackage Com.xfeng.anotherapp;import Android.content.componentname;import Android.content.intent;import Android.support.v7.app.appcompatactivity;import Android.os.bundle;import Android.view.view;public Class Mainactivity extends Appcompatactivity implements View.onclicklistener {

The previous chapter documented the cross-application launch service, before learning the difference and usage of startservice in Bindservice.Using the Bindservice method, the activity requires the service to return a binder object, so if two applications are implemented, this involves a aidl concept. Aidl (Android Interface Definition Language) is an IDL language used to generate interprocess communication between two processes on

Sometimes you may not like the Default Application icons, instead of some personalized icons. In fact, it is possible for Android users to change the desktop icon. You only need some applications such as LauncherPro, GO Launcher EX, Apex Launcher, and Nova Launcher to help you replace the icons. There are a lot of icons on the Internet for you to choose and select, but they are too scattered. It may not be easy to find the one you like. In this articl

The four ways Android boots are standard,singletop,singletask,singleinstence, respectively.Standard is the most common way to start an activity and is the default way to start. When you start an activity, he goes to the top of the stack at the back of the stack. The system does not control whether the stack has the same activity, in the same way as after-in first-out.Singletop mode is when the activity starts, the system first determines whether the t

appearance of the CardView: Use the Card_view:cardcornerradius property to set the radius of the fillet in the layout file.Use the Cardview.setradius method to set the radius of the fillet in Java code.Sets the background color of the card, using the card_view:cardbackgroundcolor property. Below is an example of a CardView included in an XML layout file: Card example DiagramCard example DiagramStrumRecyclerview can be seen through the above. It's a lot like the ListView we used t

There are several ways to implement multi-language switching for Android applications, and there are a lot of information on the web, and there is a simple and effective way.The steps are as follows:Create a new folder in the resource file Values-en, Create a new Strings.xml, copy the contents of the Strings.xml in the default values folder to Strings.xml in Valu

Today in the use of 360 mobile phone assistant, found that it will automatically create a quick start mode, it feels very interesting, so on the Internet Baidu Some methods, try, there is a way is quite good, I use for reference, first save, I also wrote a Test applet.First, add the code in the mainactivity you want to launch the app into, and in the OnCreate () method, plus a method createshortcut ();Then there is the implementation of the method:private void CreateShortcut () {//TODO auto-gene
