Android development Tips (2)

1. Dagger2 development sequence

Module-> Component-> Application
FirstModule)Create a class instance to be provided, and then add the moduleComponent)And provide the class to be injected, and add the componentApplication)And provides interfaces.

// Module @ Modulepublic class TestAppModule {private final Context mContext; public TestAppModule (Context context) {mContext = context. getApplicationContext () ;}// Provides class instances @ brief users @ Provides public Context provideAppContext () {return mContext ;}@ Provides public WeatherApiClient provideWeatherApiClient () {return new MockWeatherApiClient ();}} // Component @ appsent @ Component (modules = TestAppModule. class) // registration module public interface TestAppComponent extends AppComponent {void inject (MainActivityTest);} // application public class TestWeatherApplication extends WeatherApplication {private TestAppComponent mTestAppComponent; @ Override public void onCreate () {super. onCreate (); mTestAppComponent = DaggerTestAppComponent. builder (). testAppModule (new TestAppModule (this )). build () ;}// provide the component @ Override public TestAppComponent getAppComponent () {return mTestAppComponent ;}}

2. JRebel

You can refresh some project modifications without compiling the Android debugging tool. However, the function has been replaced by Android Studio 2.0 and will be released later.

3. Data Binding)

DataBinding separates data from pages and is more in line with the object-oriented programming mode.
Layout settings

<code class="hljs haskell">    <data>        <variable name="weatherData" type="clwang.chunyu.me.wcl_espresso_dagger_demo.data.WeatherData">    </variable></data>            <textview android:id="@+id/temperature" android:layout_centerinparent="true" android:layout_height="wrap_content" android:layout_marginbottom="@dimen/margin_large" android:layout_margintop="@dimen/margin_xlarge" android:layout_width="wrap_content" android:text="@{weatherData.temperatureCelsius}" android:textappearance="@style/TextAppearance.AppCompat.Display3" tools:text="10°"></textview></code>

Logical settings

Private ActivityMainBinding mBinding; // page binding class mBinding = DataBindingUtil. setContentView (this, R. layout. activity_main); // bind the page to mBinding. weatherLayout. setVisibility (View. VISIBLE); // use IdmBinding. setWeatherData (weatherData); // bind data

4. ClassyShark

The SDK for viewing Apk information is very powerful and does not require any decompilation steps. Its main functions are as follows:
(1) dex details in MultiDex.
(2) Use NativeLibrary details.
(3) Class details.
(4) Quantity statistics.

5. CocoaPod Installation

Upgrading the Mac system may cause the Pod command to disappear and you need to reinstall the Pod.

sudo gem install -n /usr/local/bin cocoapods

6. LaunchMode

LaunchMode includes four modes,
(1) standard, standard mode, restart and recreate example, default.
(2) singleTop: Stack top reuse mode. It is located at the top of the stack and cannot be created during startup. onNewIntent is called.
(3) singleTask, in the stack reuse mode, is not created and onNewIntent is called.
(4) singleInstance, in single-instance mode, is located in a single task stack and reused.

OK, That's all! Enjoy It
