Addendum: The Android framework provides many helpers for one-off work, background work, etc, which may be preferable over trying to roll your own thread in many instances. As mentioned in a below post, AsyncTask is a good starting point to look into. I encourage readers to look into the framework provisions first before even beginning … Read more
There is no distinction as far as Spring is concerned. By convention you can mark DAO classes with @Repository and services with @Service. Also the former does some persistence layer exception translation. Since you are asking theoretically: DAO should perform raw database operations and translate them to some higher level constructs (objects, collections). Services should … Read more
I found a solution worked for me by calling Settings.Secure.putString(getContentResolver(), Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES, “pkgname/classname”); Settings.Secure.putString(getContentResolver(), Settings.Secure.ACCESSIBILITY_ENABLED, “1”); Where the pkgname is your package name and the classname is the class name of your accessibility service. If you need to enable several services or you don’t want to destory the previous settings you might want to use : … Read more
You may still have some problems with the permissions in your data directory. Especially if you have run mongod from the terminal to start with. I find that the data files are created under root not the mongodb user when you run from the terminal. To fix .. sudo chown -R mongodb:mongodb /var/lib/mongodb/*

It is possible for an executable to actually contain multiple services.

Each service is implemented (in .NET) as a different class. But the multiple services (if they’re all started) would share an AppDomain (I believe). … Read more
add shebang to the script #!/bin/bash sudo java -jar “/home/ubuntu/FirstWebAppWithoutDB.jar” and execution permission chmod +x spring-start.sh
Use -w option with launchctl. $ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist -w Overrides the Disabled key and sets it to false.
I must disagree with @Darko. In Swift 2, use protocol oriented programming and the simple reflection offered by Mirror class : protocol JSONAble {} extension JSONAble { func toDict() -> [String:Any] { var dict = [String:Any]() let otherSelf = Mirror(reflecting: self) for child in otherSelf.children { if let key = child.label { dict[key] = child.value … Read more
Controllers are typically used to be bound with a view. Controllers manage a view’s life cycle, and should be thought of as View Controllers. A new controller will be created for each instance of a view, meaning that if you navigate away from a certain view, and then back again – or if you have … Read more
