【问题描述】：
我正在用 Flutter 开发一个应用程序。它曾经工作正常，我一直在安装它，在手机上使用它 2 个月。今天突然，当我运行这个命令flutter run时出现以下错误。
adb: failed to install D: \Flutter BLE May 2022\ SW_Mobile_Platform\ build\ app\ outputs\ flutter - apk\ app.apk: Failure[INSTALL_PARSE_FAILED_MANIFEST_MALFORMED:
Failed parse during installPackageLI: /data/app / vmdl116305539.tmp / base.apk(at Binary XML file line #187):
org.altbeacon.beacon.startup.StartupBroadcastReceiver: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when
intent filters are present]我已经在我的活动清单中添加了android:exported="true"。这是我的Manifest 文件：
