我只是想用虚幻引擎4设置一个测试应用程序并将其打包到我的手机上。这只是一个空的入门关卡，因为我想确保我正确设置了Android CodeWorks，并且可以打包游戏并使其在手机上运行。一切都运行顺利，直到将APK和OBB文件实际安装到我的手机上。下面是我正在获得的日志，据我所知，没有任何问题。

E:My GamesFirstGameTwinStickShooterAndroid_ATC>E:NVPACKandroid-sdk-windowsplatform-toolsadb.exe install TwinStickShooter-arm64-es2.apk
Failed to install TwinStickShooter-arm64-es2.apk:
There was an error installing the game or the obb file. Look above for more info.
Things to try:
Check that the device (and only the device) is listed with "ADB$ devices" from a command prompt.
Make sure all Developer options look normal on the device
Check that the device has an SD card.
我已经检查以确保我的设备显示"ADB 设备"命令，并且我很确定我的所有开发选项都可以使用，因为我只需要激活USB调试，对吗？至于SD卡，有一个，它有足够的空间，我的内部存储也是如此。
我真的很困惑，并希望任何人能提供任何帮助。感谢您抽出宝贵时间，并提前非常感谢您。另外，我对此真的很陌生，所以如果问题的解决方案如此简单，我深表歉意。
我只是弄乱了手机上的设置并解决了这个问题。对于可能遇到相同问题的其他任何人，将手机连接到PC并打开USB调试，向下拖动以调出菜单，单击android系统通知，然后将USB传输设置从文件传输更改为图像传输。它立即对我有用。
