我的应用程序在Android模拟器上运行正常。当我尝试在我的设备上运行它时，LogCat列会向我提供没有此类列的信息：USERNAME。 在模拟器上我的SQLite数据库是正常创建的，我可以添加新用户和签名但在设备中有一个例外，当我尝试这样做时。
当我尝试创建新用户时，这是一个日志文件：

任何人都可以提供帮助吗？

您可能在不增加DATABASE_VERSION的情况下更改了数据库架构，因此新应用程序正在查找旧数据库。
namespace App\Http\Middleware;
use Closure;
class CustomAuthRedirectMiddleware
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$grupoRoute = $request->route()->getGroup();
if($grupoRoute == "adminRoutes"){
return redirect('/admin/login');
}else{
return redirect('/login');
}
return $next($request);
}
}
应该修复它。

尝试在设备上卸载应用程序并重新运行。
