Ok I'm in a sticky situation here.
I decided to make an app for my anniversary that shows a notification with a message every day at 8 a.m. That's it no complicated interface or anything.
Thing is I might have got myself way in over my head since although I'm not very new to programming I am new to android studio and java.
So do you guys know any sites and/or that would help me make this very simple app since I don't really know what to search for?
Thanks in advance.
I would suggest starting with the activity tutorial.
Then, have the activity create a notification .
Now you probably want to use the AlarmManager tocreate a notification every day at a set time.
My guess is that the final activity will have buttons to toggle the repeating alarm (set with AlarmManager) on or off. This alarm will persist even when you close out of the app/activity. When the 'alarm' goes off you can point to a routine that creates the notification.
Having it all working together might be hard (I am a newbie in Android) but these are the core components you would need and taking it one step at a time will help ! If I have time I will try to come up with a skeleton.

I got a mine craft server online (https://server.pro/control-panel/1446793/) and I need to click the restart button every 45-55 Minutes. How can I do this? Is it possible to Do using GC (google code)? If not do i use java? Is it even possible? I have no idea what to do. Any response is helpful (even if it says something I have done wrong :) )
If i do need to use JAVA what program would i use to make the script (If there is one)
I am not familiar with either of those languages, however I have made an autoclicker in C. It can be found here. If you are unwilling to use mine, there are many other autoclickers out there.
There are many ways to do it. You could write some javascript that is injected into the page by plugin. You could also do it in Java with a Robot although that would be more hacky than the first solution. Also the Selenium library may help you as it's used for writing tests that will click different things on the web page.
You don't need to click the button from the remote to restart the server.
You can do that with a plugin, for example auto-restart plugin

We have a strange requirement where we have to trigger 1k android apps for a digital wall having devices. We do not have WLAN/INTERNET connection.We want to run an animation in all the devices , synced together.For this we need a trigger to initiate android apps.
I was working with Sound frequency check, but not sure if it is feasible to trigger each and everyone without lag.
Please provide any other suggestions.
You can use a time-based trigger. I expect that you have at least connection to a your mobile provider network which you can use to synchronize clocks. Once you do that, you can use any means of communication with the devices to notify them about the next time to run your animation at a given time.
For example, you could send a SMS message with the time to all devices containing the time when to trigger the animation. There will be a lag before all messages are delivered but if the trigger time is in future further than maximum lag, you will still achieve synchronization.
Or you can use another sensor, such as microphone, camera, maybe even Bluetooth. If you write your application to be triggered by a clap or flash, all devices may trigger at a reasonably similar time (especially if they were the same model with the same installed apps). It depends on how much precision you require. If e.g. sound is not precise enough, you can improve synchronization with time again - set the animation to run at the nearest second/ten seconds/... boundary after the trigger event.
All in all, it depends on your exact requirements (precision, ...) and you will probably need to do some experimenting. Internet connection would probably be the most precise trigger, though. Almost all Android devices have access to WiFi and setting up an access point is not difficult

I am aware of the Startup Splash screens in Android which I have used in my application during initial resource load.
In additional to the splash screen, I have 3 screens which shows a basic guide or tutorial of what the application is about. I need these screens to come only during first installation. Otherwise, these screens should not come. Any help with tutorial or steps to do is greatly appreciated.
Thanks
You can set up a flag in your shared preference, and after showing the tutorial for the first time you can set it to true. Every time when the app launches check for this flag, if the flag is set true then dont show the tutorial.

I am looking for a library that will allow me to work with sound. This is just something that occurred to me and the problem is that in a large music collection I need to find tracks similar to another reference track . The simplest of things would be to find tracks with the same/almost-the-same tempo . Is this possible and are there any tools available for this ?
Finding music which is similar to other music is quite a complex field, and will probably require quite a bit of work if you're willing to spend quite a bit of time. If Java is your language of choice, then you could have a look at coMIRVA which will let you compare music based on timbre. From my experience, doing comparisons on that single dimensions isn't always good enough, but it is at least a start.
There's always the other path, which is to use an already existing commercial offering such as the Echo Nest and BMAT. I don't know what they cost, but it's probably quite pricey. However, these are products that have taken years to develop so I assume they must at least provide some sort of value.

So we have a web application and we keep changing user interface. Sometimes user asks to tell them about new features and changes. Previously we have sent a group email to let our users know about new features and changes. But email thing is tedious sometimes. Is there any easier way to dynamically announce on everyone's application that these features have been added? Are there any examples , apis for this? I am looking for any apis particularly in Java.
You could have a page on your web app (like a news/updates/announcements page) for this kind of thing. If you are planning major changes then put an article on the news page a little in advance, maybe with some screenshots, so the users know that change is coming.
When the news page changes (ie you have a new announcement to make) then make the link to the page more obvious, a bit like stackoverflow.com does with the link to the blog page.
