Crash when closing soft keyboard while using native activity

由 天涯浪子 提交于 2021-02-18 02:29:00
问题 We are developing an indie game for android and would like the user to choose his nickname. We have chosen to use the Native Activity that is provided by the NDK as that seemed to be the easiest way to go. The first problem we've encountered with the keyboard was that the function ANativeActivity_showSoftInput() seems to do nothing at all (as described e.g. here), so we bring up the keyboard using JNI calls to function: static void showKeyboard(Activity activity) { String s = Context.INPUT

Datagram Transport Layer Security (DTLS) on Android/Java

问题 Has anyone used DTLS on Android or is there an open source Java implementation that supports DTLS? What are my other options for securing UDP traffic on Android? 回答1: DTLS support is not available in pure Java yet. We ended up using OpenSSL through JNI. I doubt you will find anything on Android. You should use TLS (which means you have to use TCP). 回答2: wolfSSL recently created an open source JNI wrapper around the lightweight SSL/TLS library, CyaSSL. The wrapper supports both DTLS 1.0 and

鸿蒙和安卓，到底有什么区别？

来自： 程序员小枫 在 9 月 10 日召开的华为开发者大会上，宣布了鸿蒙2.0 系统正式面世，同时开启了 Beta 版本的测试和开源网站。 对于开发者来说两个最关键的点值得关注： 一个是 Beta 版的开发工具，一个是开源网站。 开源网站 在开发者大会上宣布将 HarmonyOS源代码捐赠给中国开放原子开源基金会，并在大会上公布了鸿蒙系统的开源路线。 OpenHarmony 官方源码地址： https: //openharmony.gitee.com/openharmony 开发工具 鸿蒙使用基于 Intellij IDEA 深度定制研发的 DevEco Studio 作为其开发工具。 DevEco Studio 下载地址： https: / /developer.harmonyos.com/cn /develop/deveco -studio 那么，在应用开发过程中，HarmonyOS（鸿蒙）和 Android（安卓）开发环境有什么不同呐？ HarmonyOS 项目和 Android 项目对比 资源目录的变更 ①资源目录名称有更改 安卓 res 目录，这里用 resources 目录，它包括 base 和 rawfile 两部分，其中 base 是核心的资源目录，常用的都放在这里面，便于查找和使用。rawfile 会原封不动打包到生成的应用里面。 安卓是 res/values

Android 9.0适配遇到的问题1

文章同步自 javaexception 本周在适配Android 9.0，过程中碰到了小问题 问题1: SSL handshake timed out 解决办法： Android 9.0 开始，默认不允许明文传输，所以在建立网络连接时会使用 https 连接，同时进行安全认证。如果应用没有做对应处理，即会发生上述异常。 在应用中的res/xml目录添加network_security_config.xml文件。内容如下 <?xml version="1.0" encoding="utf-8"?> <network-security-config> <base-config cleartextTrafficPermitted="true" /> </network-security-config> 接着在androidManifest.xml文件的<Application>标签里面添加android:networkSecurityConfig="@xml/network_security_config"即可解决此问题 问题2: Android p 设备报错java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/ProtocolVersion 解决办法: 在androidManifest.xml文件的
