Cold Drawn Plug when the application is deployed, the project is split into 10 parts, each with its own. dex file, and all classes are assigned to the appropriate. dex file based on the package name. When the cold plug is turned on, the. dex file for the modified class is reorganized to generate a new. dex file and then deployed to the device. The reason you can do this is to rely on Android's ART mode, which allows you to load multip

You can create multiple avds as needed based on the device type you want to simulate. To thoroughly test the application, you need to create an AVD for each specific device configuration (for example, different screen sizes and platform versions ). Test the application on each AVD to ensure its compatibility.
When selecting a system image for AVD, remember the followin

Configure Gradle build and gradle buildBuild basic configuration
Android Studio contains a top-level build file and a build file for each module. A build file is called build. gradle. It is a plain text file that uses Groovy syntax to configure the elements provided by the Android Gradle plug-in. In most cases, you only need to edit the module-level build file. For example, the build file of the app module of the BuildSystemExample project is as follows:
Apply plugin: 'com. android. app
to open android-studio, choose File> Setting> IDE Settings> Plugins, and click Install Plugin from disk on the right ].
Restart android-studio and find an icon in the toolbar. Click it. The first configuration points to the installation path of Genymotion.
In this way, you can select a simulation device each time you start it.

Table 1. A simple action bar with app icons and activity titles.
To set a basic action bar, your app needs to use a topic with the action bar enabled. How to request such a topic depends on the minimum supported version of your app. This lesson is divided into two chapters based on your minimum supported Android version.
Only Android 3.0 and above are supported
From Android 3.0 (API level 11), the action bar is included in all the a

The top level script blocks is listed below.Approximate meaning statments can include method invocation, attribute assignment, local variable definition, and script Bolck is a method whose parameters can be a closure. This closure is a configuration closure because it is used to configure the delegate object when it is executed.

narrow screen device, these navigation option labels may be filled in the main operation bar, instead of being separated to the stacked operation bar. In particular, If you disable the icons and titles in the Operation column (using the setdisplayshowhomeenabled (false) and setdisplayshowtitleenabled (false) methods), the navigation option label is folded into the main operation column, for example, 3 shows the second device:

2. Retain the Android: minsdkversion attribute to ensure that the attribute value is the API level that your application must be compatible.
3. To compile your application, change your compilation goal to API Level 8. This is required because the older Android class library does not understand the Android: installlocation attribute, so your application will not be compiled when this attribute exists.
