java - android 应用程序中的红外线实现导致它崩溃

标签 java android infrared

如果我取消注释我的方法 sendIrCode 中的任何代码，那么我的应用程序将在按下按钮时崩溃，该按钮运行方法 sendIrCode。虽然采用这种格式，但我可以获得 We have liftoff 和 Ultra liftoff 打印到屏幕上，但就像我之前说的那样，一旦我取消注释传输它就会崩溃。我已经尝试在两部不同的手机上运行这段代码，并且都可以使用 hasiremitter() 方法并像他们应该的那样返回 true，但这是我能够正常工作的 ConsumerIrManager 的唯一功能，任何帮助将不胜感激。

我还逐字使用了此链接中的代码位，没有任何变化。 https://android.googlesource.com/platform/development/+/master/samples/ApiDemos/src/com/example/android/apis/hardware/ConsumerIr.java

因此 API 文档甚至没有暗示您需要请求 Ifrared 许可这一事实，因此通过在我的 list 文件中看到它，我能够解决我的问题

http://developer.android.com/reference/android/Manifest.permission.html#TRANSMIT_IR

最佳答案

你的问题里面有答案:

 Caused by: java.lang.SecurityException: Requires TRANSMIT_IR permission

将权限放在您的 list 中；)
