Delphi Android App在键盘连接/断开连接时崩溃

Question

创建Android应用，删除编辑框，运行应用。

• 连接条形码扫描仪，App Crash。
• 连接条形码扫描仪并运行应用程序，一切正常。
• 断开扫描仪和应用程序崩溃。

如果应用程序运行，您无法连接/断开键盘/条形码扫描仪，无论是蓝牙还是有线。

有什么想法吗？

与App crashes when closing Keyboard on Android Delphi Xe7相似 但这不是同一个问题。

运行应用程序中的LogCat，然后连接条形码扫描器

来自Embarcadero Community site的解决方案（更新了Ernie Thomason建议的其他项目）

您需要将keyboard添加到Android清单模板AndroidManifest.template.xml中，以避免在连接/断开外部USB键盘时终止应用。

当前档案：

android:configChanges="orientation|keyboardHidden"

更新文件：

android:configChanges="orientati‌​on|keyboard|keyboardHidden|navigation|screenLayout|screenSize"

以下是有关模板文件的一些其他信息：

构建项目时，RAD Studio使用AndroidManifest.template.xml作为模板在输出目录中生成AndroidManifest.xml。您需要编辑与项目位于同一文件夹中的模板文件。
