Can't play sound on button click using playSoundEffect(SoundEffectConstants.CLICK)

由 不打扰是莪最后的温柔 提交于 2021-02-19 00:41:17
问题 I have the following 2 lines of code: myButton.performHapticFeedback(HapticFeedbackConstants.VIRTUAL_KEY); myButton.playSoundEffect(SoundEffectConstants.CLICK); When I press the button, haptic feedback works fine but no audio is heard. Anybody had this problem when they started with Android? 回答1: I had this problem and it turned out to be something quite stupid on my part. I had disabled "Audible Selection" for the entire phone. On the home page, it's on Settings-->Sound-->Audible selection.

How to include versioned *.so file into apk using Gradle?

由 旧街凉风 提交于 2021-02-18 23:45:50
问题 I trying to build android application with some precompiled native libraries: liba.so and libb.so.1.2.3 Libraries are placed into jniLibs subdirectory. After building APK file, only liba.so included into it, but not libb.so.1.2.3 . Result is predictable. Application crashes at start. What to do with build scripts to include all files from jniLibs into APK? 回答1: Unfortunately I don't develop for Android anymore, so I can't test this, but I know Gradle and this might work for you.

Android面试题集：以前烂大街的四大组件-Activity，面试重提这些知识点你还记得吗?

由 风流意气都作罢 提交于 2021-02-18 23:15:16
前言 虽然有很多面试的文章里都有这些题目，但是我每次在看的时候，总是会觉得有些分散，复习的时候还要重新去找到对应的文章，所以我就想着自己来整理一下，并且把题目给分一下类型；自己整理可以帮助我复习的同时还可以巩固一遍；这次主要是4大组件相关，后续我会继续整理，觉得有帮助的可以点个赞。 接下来是关于Activity的面试题了： 描述一下Activity 生命周期？ onCreate() Activity第-次被创建的时候调用，一些初始化操作可以在这里完成。 onStart() 这个方法在Activity 由不可见变为可见的时候调用。 onResume() 这个方法在Activity 准备好和用户进行交互的时候调用。此时的Acivity一定位于返回栈的栈顶，并且处于运行状态。 onPause() 这个方法在系统准备去启动或者恢复另-个Activity的时候调用。 onStop() 这个方法在Activity 完全不可见的时候调用。它和onPause()方法的主要区别在于，如果启动的新Activity 是一个对话框式的Activity,那么onPause()方法会得到执行，而onStop()方法并不会执行。 onDestroy() 这个方法在Activity被销毁之前调用，之后Activity的状态将变为销毁状态。 onRestart

Detecting when the system ui is visible with sticky immersive mode

由 回眸只為那壹抹淺笑 提交于 2021-02-18 22:59:48
问题 When using sticky immersive mode (https://developer.android.com/training/system-ui/immersive.html) neither the View.OnSystemUiVisibilityChangeListener is called nor will any visibility flags be cleared (like View.SYSTEM_UI_FLAG_HIDE_NAVIGATION): Sticky flag—This is the UI you see if you use the IMMERSIVE_STICKY flag, and the user swipes to display the system bars. Semi-transparent bars temporarily appear and then hide again. The act of swiping doesn't clear any flags, nor does it trigger your

How to minimise/hide app programmatically?

由 前提是你 提交于 2021-02-18 22:45:12
问题 I have an activity which is purely transparent (user can't see when it gets open).I open this activity from background service whenever I want to open it. After doing some work, I need to close that activity (not finish() ).I want to hide or minimize app. Actually, my app opens up for a second and do someWork after doing someWork , it continues to do remaining work (some uploading process) in background i.e. in onPause .I don't want user to know that something opens & closed immediately.
