我正在尝试启动一个仅打印“服务”的简单服务。但是，就像我的服务从未执行过（至少我在应用程序输出中看不到来自它的任何消息）。
这是我的main.cpp
#include <QAndroidService>
#include <QDebug>
#include <QGuiApplication>
int main(int argc, char *argv[]) {
if (argc == 1) {
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc, argv);
qDebug() << "Application debug!!!";
return app.exec();
}
else {
QAndroidService app(argc, argv);
qDebug() << "Service debug !!!";
throw "lol";
app.exec();
}
}
这是我的AndroidManifest。
