I have a Meteor app that runs fine when using meteor run android-device but shows a white screen when running the resulting APK built by meteor build. When I look at the remote debugger I see that the application is trying several times to connect to the following URL with different cb param values, only to have the connection cancelled: https://myapp.co.com/sockjs/info?cb=asdfasdf.
Taking the same build, I run the iOS project through XCode on the simulator or iOS device and it connects and runs just fine. I also can go to the website and connect through a browser and the /sockjs calls connect.
Any idea why this is happening just with Android?
I have tried many things over the past few days so I’m running out of options. I tried setting the DDP_DEFAULT_CONNECTION_URL to the same hostname as my ROOT_URL. I also tried setting the MOBILE_ROOT_URL and MOBILE_DDP_URL as well with the same hostname. Still no joy.
Here is how I’m building my app:
meteor build ../dist --server=https://myapp.co.com:443 --mobile-settings ./settings.json
(note the = sign; I’ve tried with and without it)
Once the unsigned APK is created, I sign it with jarsigner and zipalign it.
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 release-unsigned.apk my-keystore
$ANDROID_HOME/build-tools/25.0.3/zipalign -f -v 4 release-unsigned.apk final.apk
Here’s the code the client initially hits in main.ts (it’s an Ionic app):
Meteor.startup(() => {
// Switch to PROD mode for Angular if prod
console.log("METEOR_SETTINGS = " + JSON.stringify(Meteor.settings));
if (Meteor.settings.public.MODE.startsWith("prod")) {
enableProdMode();
}
Meteor.call('reauthenticateUser', (err, user) => {
if (err) {
console.log("Error connecting to authentication services. Please try again later.", err);
platformBrowserDynamic().bootstrapModule(AppModule);
}
else if (user) {
console.log("user = " + user);
Meteor.call('getUser', null, (err, user) => {
console.log("gotUser");
Session.set('user', user);
platformBrowserDynamic().bootstrapModule(AppModule);
});
}
else {
console.log("else");
platformBrowserDynamic().bootstrapModule(AppModule);
}
});
});
The above code results in me seeing the METEOR_SETTINGS but nothing from what’s inside the Meteor.call(). Again, on iOS and Web I do see the values as expected.
The server application is a Docker image built with launchpad and I use HAProxy to route 443 with a Verisign SSL Cert to port 3000 on the Meteor container.
Any help would be greatly appreciated!
