Yes, a blocking operation in a Service will still block the application. Despite first appearances, Services are not simply for running tasks in the background. They are for running tasks with a lifecycle that is independent of the Activity lifecycle (IE, they may continue after the Activity is closed). A Service that starts and ends … Read more
So I finally figured it out. It turns out that TabSpec cannot bind to activities Using getApplicationContext().bindService instead of just bindService on your activity solves the problem as it is using the higher level application context. Hope this helps someone!
NOTE: NOW THIS ANSWER IS ONLY VALID FOR ANDROID 7 AND BELOW. SINCE ANDROID 8 GOOGLE HAS CHANGED HOW BACKGROUND TASKS ARE HANDLED Since I posted this question, I have implemented two different approaches to this solution into multiple apps. APPROACH 1 This extract is from an app where I use push notifications, which need … Read more
As you wrote that the task is about monitoring 3-rd party applications, there is no solution other than periodically read a list of processes and detecting foreground process. You need a service for this. Unfortunately, Android does not provide means such as broadcast events for foreground process change. The task requires a lot of code … Read more
How can I wait for ServiceConnection.onServiceConnected being called reliably? You don’t. You exit out of onCreate() (or wherever you are binding) and you put you “needs the connection established” code in onServiceConnected(). Are all the event handlers: Activity.onCreate, any View.onClickListener.onClick, ServiceConnection.onServiceConnected, etc. actually called in the same thread Yes. When exactly is ServiceConnection.onServiceConnected actually going … Read more
I assume that the first error (undefined property) happened before you added the property and the constructor. Then you got the second error. This other error means that your constructor expects to receive a Container object but it received nothing. This is because when you defined your service, you did not tell the Dependency Injection … Read more
Edit: you should now use brew services start mongodb, as in Gergo’s answer… When you install/upgrade mongodb, brew will tell you what to do: To have launchd start mongodb at login: ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents Then to load mongodb now: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist Or, if you don’t want/need launchctl, you can just run: mongod It … Read more
You need to open the Service.cs file in the designer, right click it and choose the menu-option “Add Installer”. It won’t install right out of the box… you need to create the installer class first. Some reference on service installer: How to: Add Installers to Your Service Application Quite old… but this is what I … Read more
The common answer to this problem is that you have to restart your device. Surely you cannot tell your users to restart device in order for your app to function, so my solution was to use a HTTP fallback, here is the AsyncTask I use in my code. You will have to modify it for … Read more
I would definitely suggest using Google Cloud Messaging here. This has the benefit that once a device runs your app, you can make it register against GCM and you can send them some message that would make them register their coordinates into your database. This approach would need that you have to implement some server … Read more
