Android Development Tips (2)

Welcome to follow my GitHub and follow my csdn.

I'll introduce some interesting little points about Android. Previous article.

1. Dagger2 Development Sequence

Application, Component, Module
The module first creates an instance of the class that needs to be provided, and then adds the module to the component (Component) and provides the classes that need to be injected, and finally adds the component to the application (application) and provides the interface.

//Module@Module Public  class testappmodule {    Private FinalContext Mcontext; Public Testappmodule(Context context)    {mcontext = Context.getapplicationcontext (); }//Provide class instances    @AppScope    @Provides     PublicContextProvideappcontext() {returnMcontext; }@Provides     PublicWeatherapiclientprovideweatherapiclient() {return NewMockweatherapiclient (); }}//Components@AppScope@Component(modules = Testappmodule.class)//Registration module Public  interface testappcomponent extends AppComponent {    voidInject (mainactivitytest test);}//Application Public  class testweatherapplication extends weatherapplication {    PrivateTestappcomponent mtestappcomponent;@Override  Public void onCreate() {Super. OnCreate (); Mtestappcomponent = Daggertestappcomponent.builder (). Testappmodule (NewTestappmodule ( This). build (); }//Supply Components    @Override     PublicTestappcomponentgetappcomponent() {returnMtestappcomponent; }}

2. JRebel

Android Debugging tools, without compiling, you can refresh some project modifications. However, the feature has been replaced by Android Studio 2.0, waiting for the 2.0 official release.

3. Data binding (DataBinding)

DataBinding implements the separation of data from the page, more in line with the object-oriented programming model.
Layout settings

< Data><variable name="Weatherdata"             Type= "Clwang.chunyu.me.wcl_espresso_dagger_demo." data. weatherdata"/></ Data><TextViewAndroid:id="@+id/temperature"Android:layout_width="Wrap_content"android:layout_height="Wrap_content"Android:layout_centerinparent="true"Android:layout_marginbottom="@dimen/margin_large"android:layout_margintop="@dimen/margin_xlarge"android:text="@{weatherdata.temperaturecelsius}"Android:textappearance="@style/textappearance.appcompat.display3"tools:text="10°"/>

Logical Settings

private// 页面绑定类mBinding = DataBindingUtil.setContentView(this// 绑定页面// 使用Id// 绑定数据

4. Classyshark

The software to view the APK information is very powerful, eliminating the steps to decompile, the main features:
(1) For more information on Dex in Multidex.
(2) Use nativelibrary for more information.
(3) Class details.
(4) Quantity statistics.

5. Cocoapod Installation

Upgrading your Mac system may cause the pod command to disappear and you will need to reinstall the pod.

-n /usr/local/bin cocoapods

6. Launchmode

The Launchmode consists of four modes,
(1) Standard, Normal mode, start re-create example, default.
(2) Singletop, stack top multiplexing mode, located at the top of the stack, boot will not be created, call onnewintent.
(3) Singletask, stack in the reuse mode, the presence will not be created, call onnewintent.
(4) SingleInstance, single-instance mode, separate in a task stack, reuse.

OK, that ' s all! Enjoy It
