override fun onStop() { axbells.ga() axbells.gaCallbacks(runnable) axbells.gaMessages(0) } Now, lets the discuss the Reactive Way. Reactive Way. In this blog, we will be learning the new way to create Splash Screen using axbells.ga will be using RxJava Timer operator in this blog. Implement the interface on Android up to Android To create an implementation of InputManagerCompat that supports Android up to Android , you can use the following objects: A SparseArray of device IDs to track the game controllers that are connected to the device. A Handler to process device events. Android蓝牙打开和关闭的流程基本一致,这里就从打开的流程进行分析。 1 UI 从UI上看蓝牙开关就是设置settings里那个switch开关,蓝牙开关操作封装在Set.

If you are supporting game controllers in your game, it's your responsibility to make sure that your game responds to controllers consistently across devices running on different versions of Android. This lets your game reach a wider audience, and your players can enjoy a seamless gameplay experience with their controllers even when they switch or upgrade their Android devices. This lesson demonstrates how to use APIs available in Android 4. The examples in this lesson are based on android removemessages(0) reference implementation provided by the sample ControllerSample.

This sample shows how to implement the InputManagerCompat interface to support different versions of Android. To compile the sample, you must use Android 4. Once compiled, the sample app runs on any device running Android 3. Suppose you want to be able to determine if a game controller's connection status has changed on android removemessages(0) running on Android 3. However, the APIs are only available in Android 4, android removemessages(0).

To help you determine which features require such a fallback mechanism for older versions, table 1 lists the differences in game controller support between Android 3. Table 1. APIs for game controller support across different Android versions.

You can use abstraction to build version-aware game controller support that works across platforms. This approach involves the following steps:. For an overview of how android removemessages(0) can be used to ensure that applications can work in a backward compatible way across different versions of Android, see Creating Backward-Compatible UIs.

To provide backward compatibility, you can create a custom interface then add version-specific implementations. One advantage of this approach is that it lets you mirror the public interfaces on Android 4. The InputManagerCompat interface provides the following methods:. Next, create implementations for InputManagerCompat that work across different platform versions. If your game is running on Android 4. However, if your game is running on Android 3, android removemessages(0).

Regardless of which version-specific implementation is used at runtime, the implementation passes the call results back transparently to the game. Figure 1. Class diagram of interface and version-specific implementations. The InputManager is obtained from the system Context. To create an implementation of InputManagerCompat that supports Android 3. A Handler to process device events, android removemessages(0). When an app is started or resumed, the Handler receives a android removemessages(0) to start polling for game controller disconnection.

The Handler will start a loop android removemessages(0) check each known connected game controller and see if a device ID is returned. A null return value indicates that the game controller is disconnected. The Handler stops polling when the app is paused. A Map of InputManagerCompat. InputDeviceListener objects. You will use the listeners to update the connection status of tracked game controllers. This method checks if an attached game controller has been disconnected and notifies registered listeners.

To detect that an input device has been added, override the onGenericMotionEvent method. When the system reports a motion event, check if this event came from a android removemessages(0) ID that is already tracked, or from a new device ID. If the device ID is new, notify registered listeners. Notification of listeners is implemented by using the Handler object to send a DeviceEvent Runnable object to the message queue. When the DeviceEvent runs, the appropriate callback method of the listener is called to signal if the game controller was added, changed, or removed.

You now have two implementations of InputManagerCompat : one that works on devices running Android 4. The version-specific switching logic is implemented in a class that acts as a factory. InputDeviceListener in your main View. Because of the version-switching logic you set up, your game automatically uses the implementation that's appropriate for android removemessages(0) version of Android the device is running.

Your game should now be able to process game controller events consistently on devices running Android 3.

Implement the interface on Android up to Android To create an implementation of InputManagerCompat that supports Android up to Android , you can use the following objects: A SparseArray of device IDs to track the game controllers that are connected to the device. A Handler to process device events. I have a situation in an Android app where I want to start a network activity (sending out some data) which should run every second. I achieve this as follows: In the onCreate() I have the code. override fun onStop() { axbells.ga() axbells.gaCallbacks(runnable) axbells.gaMessages(0) } Now, lets the discuss the Reactive Way. Reactive Way. In this blog, we will be learning the new way to create Splash Screen using axbells.ga will be using RxJava Timer operator in this blog.
