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.

Suppose I get a call at my android phone. What I want is this call to be routed to my bluetooth/wifi connected PC just like it is routed to any other android audio device.
If you have embedded Bluetooth hardware just use accompanying software and set your PC (after pairing) headset/speakers as a Hands-free device. That's it.
If you have BT USB-dongle try to install Bluesoleil software and do the same as above. It's simple but not very stable piece of s..oftware, so it may work or it may not. In this case you can try Broadcom WIDCOMM Bluetooth Driver 12.0.1.940 and again set that so you could use your PC headset as a Hands-free device.
I'm sorry I can't tell you exact steps because I don't have Bluetooth on my PC atm. But believe me it's very easy. It was some time ago but it was like half a minute to set things up.
Hope this will help.

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 planning to build a voice authentication system for android devices. Simply meaning instead of the login screen where you have to type your password or draw the pattern, you only only need to say one word such as "Login" and the phone authenticates you and automatically unlocks the phone.
I was initially planning to implement it on windows but i am afraid that windows might not support voice bio metrics.
So my question is will android support voice bio metrics for unlocking a phone?
Are there any voice bio metrics libraries for android ?
I did a google search but couldn't really find what i wanted. I have also found out some voice biometrics apps such as nuance but their authentication is implemented for a different purpose.
Thanks.
Android does support voice authentication by its own. You can have this feature by using an external library. Several companies offer online voice biometrics, but only a few offers offline.
If you are looking for offline voice authentication I would suggest the following companies:
Neurotechnology
Agnitio
They both support multiple platforms.

I understand that during development, you are supposed to use the test devices (either xml tags or java code behind) to show test ads on your own devices to avoid clicking your own ads before releasing an app for production in the PlayStore.
My question is that once an app is in production, in the PlayStore, is it not fair game for the developer to click ads? After turning off test ads for upload to PlayStore does AdMob know that it is the developer that is clicking ads? How?
Google's stance seems pretty unambiguous to me. AdMob publisher guidelines and policies
Publishers may not click their own ads or use any means to inflate
impressions and/or clicks artificially, including manual methods.
Testing your own ads by clicking on them is not allowed.
