【问题描述】：
我有一个颤动的应用程序，它产生了一个非常奇怪的行为； 当我在设备上运行它时，它运行完美，但是，当我构建一个 apk 并将其安装在同一设备上时，我在启动屏幕后得到一个空白应用程序。
我的“flutter run --verbose”会产生以下结果：
adb: failed to install /Volumes/<my volume>/<app name>/build/app/outputs/apk/app.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.<app name> signatures do
not match the previously installed version; ignoring!]

问题： 当我在设备上“颤振运行”应用程序时，它可以完美运行并产生以前的问题......但是当我在同一设备上使用“颤振构建 apk”然后“颤振安装”时，我的应用程序是一个空白屏幕
... Flutter Doctor 没有产生任何问题，我还安装了最新版本的 Flutter。
非常感谢您在这个问题上的帮助，因为我对 Flutter 比较陌生，而且我无法从上一个堆栈中找出错误。
非常感谢。
【问题讨论】：
-
您好，您是否尝试手动卸载该应用程序？如果您在设备上有多个用户或访客用户帐户，请尝试登录该帐户并手动卸载它
-
@thusith.92 我确实卸载并重新安装了几次应用程序，但无济于事
