How do I make my WearOS app work on LockScreen? My app reacts to tapping the smartwatch on an NFC tag. I hear about widget, but it's almost dead now. Is lockscreen programming still possible in Android app development? Thanks in advance.
From: https://developer.android.com/guide/topics/appwidgets
Only Android versions lower than 5.0 support lock-screen widgets.
So lock-screen widgets have been unavailable for quite some time now.

Is it possible to use Android Things on a tablet?
My project needs Android Things, but I can't use Raspberry for it, because it will be expensive.
If not, what do I do to a "normal" Android (Android for tablets/phones) to have only my application, don't have notification bar and don't close my app with the life cycle? (like on Android Things)
It's possible to use Android things on a tablet?
No. Here is the list of supported platforms.
If not, what do I do to the "normal Android".
Develop a kiosk mode app or, if it's not enough for you, customize Android source code.
I am registering RemoteControlClient to control playback in my application. http://developer.android.com/reference/android/media/RemoteControlClient.html
it shows playback notification on android wear, but buttons play/pause/next/prev does not work on wear, volume up/down work. It also work locally on phone, so i think remotecontrolclient is registered correctly. Does someone faced up with this problem too? Any advices?
Thanks,
It seems that on Android 4.3, Android Wear only sends specific Intents that are unique to Google Play Music, rather than using the standard functionality to handle media controls. In Android 4.4, they use RemoteController to correctly send media events, in place of their custom solution on Android 4.3 (hence, why it works on those devices).
I've filed an issue with the Android Wear team to use the standard functionality, which should eventually fix this issue.
I'm planning to create myself a proof of concept Android Wear application, but I'm not planning to buy myself an Android smartwatch yet. I will buy it if I get positive reactions from my target audience once I show some of them the proof of concept app from my personal smartphone (Android Kitkat).
is it possible to run/debug an Android Wear application on my smartphone? Suggestions for third party software is welcome as well.
For a demo/proof of concept I'd say yes it's possible, in certain conditions/restrictions:
It should be a standalone/fullscreen app (it will be hard to emulate the notifications/cards behaviour)
Define a 320x320px layout for your content (or 280x280, and eventually add a round mask it you need a round watch)
Code like it's Android!
Note that behind the scene communication between the phone and the app will be different when you do it on a real Wear, but for a demo your audience will not see the difference.
You can check this app in which I use a similar layout for the watch, the handheld app and the widgets.
I have started to develop a new app for Android Wear, but now that I want to use the accelerometer, I'm a little stuck.
Since I dont have an Android Wear devide, I have tried to use SensorSimulator for simulate accelerometer events but seems that it forces close after just a while.
Any ideas of how to da that?,
thanks in advance
I think you can set up an Android Wear device by installing android wear app available on google Play & then Follow the app instructions.
And also you can create your own project.
I think this is a good link that gives you better idea onCreating & Running Wearable App :-

I'm currently developing an app for android that uses the flash. My miserable problem is that I don't have a device featuring a flashlight... Is there any emulator in the world that shows the flash state?
Thank you guys in advance!
José.
There is no emulator that can allow you test the flashlight. You need a real device for it.
You need to add the permission also to your manifest file - "android.permission.FLASHLIGHT"
If you are working with laptop then You can use bluestack to check your application related to flashlight it will work
The android emulator does not work with "flashlight apps".
I was also disappointed to hear this when I started developing my flashlight app quite some time ago. I haven't found a solution either, except for having a development device (my phone) to test the app on.
In general, it helps to have a development device on hand because the emulator is not always 100% accurate.
Best of luck.
