Answer 1

You can use Appium to install your app on your device, Just uninstall your App manually and in setUp code use absolute path of .apk file like this:
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("VERSION", "5.1.1");
capabilities.setCapability("deviceName", "Name");
File appDir = new File("/home/filename/ProjectFile");
File app = new File(appDir, "appname.apk");
capabilities.setCapability("app",app.getAbsolutePath());
It will install your app on your device.

Answer 2

You said you tried to launch on real device, but your logs saying you tried to launch on simulator.
If you are using UI version of appium, Please uncheck Force Device option in appium and give UDID of real device which you connected in appium and prelaunch. your app will be installed.
