If I want to deploy to the Android Market it looks like I have two options:
Create my own keystore and upload. When I update my app use that keystore on my APK to ensure that users are given the option to update.
Do step 1, but also implement Application Licensing which will put controls on how the app is used.
Am I correct to assume that step 1 means that anyone could copy my APK once it is purchased from the Android Market and install it anywhere they wish?
How common is it for people to use Application Licensing and is it the defacto approach?
My app will be paid and I want to ensure I am taking the best approach.

Yes you are correct, it would be extremely easy to copy your application.
How common is it for people to use Application Licensing and is it the defacto approach?
I would say it's very common since it's the only way to verify the licence against the Android Market, though I don't have any stats on this. Otherwise you would need to implement your own "Market" and verify purchases in your own.
My app will be paid and I want to ensure I am taking the best approach.
Use LVL, DO NOT use the default implementation. Watch the LVL session from the 2011 IO for a how to.
Often times, people will not simply download an app and copy it anywhere they would like. However, it is possible through some apps and other software for users to copy off APKs from their phones (even though they aren't suppose to). In my opinion, if you app is paid, you should implement Applicant Licensing. It is a very useful tool to help in preventing people from stealing your APKs (in other words, downloading it and then trying to install it some where else) as it checks on start up to ensure that the app is on the phone that purchased it. Otherwise, for free apps, I don't really see the neccessity because it's free and anyone could have downloaded it.

is it possible to create an android application that is meant only for internal use? Basically a private application not meant to be installed by non-approved phones?
If so what is the basic process of deployment? How do you get the app on the employees phone's?
thanks!
The easiest way is to email it to them. Any email with an .apk attachment will get an "Install" button that you can tap to install the app.
Installing from non-market sources needs to be enabled -- which is a bit of a security risk -- but the user will be prompted to turn that on if they need to, and even given a button that will take them right to the appropriate settings page. The whole process is really quite slick. :)
Alternatively, you can copy it to the phone (e.g. after connecting the phone in USB storage mode) and then use a file system app to locate the file and install it.
Emailing it is the easiest way, however.
Edit: I'm assuming you meant private as in "only sent to certain individuals" and you're not actually looking for a method that will prevent the apps from being run on non-approved devices should they end up on one.
There's a proper way to do it now: Google Play Private Channel for Google Apps. You publish app on Private Channel and then send invitations to users. It won't be seen by other users of Google Play.
Option 1
Using Google Play Private Channel is probably the best way, but is useful only for Google Apps users.
Option 2
You can use new Developer dashboard options that let your app be in Alpha or beta phase and is available to only selected google accounts (using groups or google plus circles). Your app can stay in beta indefinitely so not become visible to other users. if you like this method you can also use services like TestFlight.
Option 3
Mail distribution is also ok it's even mentioned in documentation which I find a little bit odd, but I would advise you to use some file storage like Dropbox and just distribute the link to selected people.
Two major ways:
You can either use the non-market application installation method, or adb from a connected PC to install an apk which you distribute as a bare file. The downside is that anyone in possession of the apk can install your application.
Alternatively, you can distribute the application through the android market, but make it require an account on a server you control in order to do anything useful. The upside is that possession of the apk doesn't get an unauthorized user much; the downside is negative ratings from confused randoms, and that you've made your apk very available for interested parties to know about and decompile. (There is or was also a way to put an app on the market but not list it so it was only accessible via a full url, however don't rely on that)
Yes. As of right now I use such a method, I have to manually load the app on the phone, however other techniques can be used. Once loaded the app checks the main server to see if it is up to date. If it is not, it downloads and installs the new version of itself.
If you go to your eclipse workspace and go to yours app's folder, in the bin folder assuming you develop with eclipse, you will find a .apk file somewhere in there. Copy it to the phone and then use something like EZ File Explorer (or something like that) to access your android filesystem, click on the .apk and it will install and be ready to use.
I published many versions so far. And, the users should use the most recent app. However, apkpure shows all the app list that I released.
How come this website take all the apk or abb? I don't want the website takes my applications and block the users in the app. Is there any way to do that?
Actually it's possible to do, using one of the Android features like app bundles. This could help you to verify non Google Play installation. Or even create behavior to crash/exit in such cases.
The whole idea of the approach, it's separation application features to different bundles which could installed be installed within Google play package manager. So you can check it's documentation.
Lots of android users can not access play store when removing the google restrictions, because they want apk file for install. Third party websites publish for that kind users, As well as some desktop users want APk file specially GAME APPs. I think they not Change original APK file.
I am going to have a alpha release of my app, which is not yet on the market. I want to have the app APK link sent out to friends via email so they can download it from my site CDN.
One question here: if I want to give them updates, what will be a good way? Can I download the new APK within the app, and somehow install the APK to replace the old one without anything to do with the market? So my friends can have the app upgraded while it is still in alpha release?
When I did it, I used Zubhium -- they were a web service with a small API that you could install into your app, giving you a mini "app store"-style backend and handling distribution for you. It would host and distribute your APK, connect up to their server when the app launched, check for updates, invalidate old versions, gather crash logs for you, etc. It was very good.
Zubhium are now https://www.vessel.io -- I presume they still have the above features as part of their now-much-bigger service, but when I checked you had to give them a credit card number even to sign up for the free plan, so I've not played with it.
A friend of mine uses http://testflightapp.com for iOS, and it looks like they have an Android version now, so that's certainly worth checking out. A quick search also shows up http://applover.me. #Janusz recommends http://hockeyapp.net/features in his comment.
As #Nanne points out in his answer, the Play Store itself now lets you distribute to limited alpha- and beta-test groups. That looks like it has fairly minimal features compared to the third-party services (no A/B testing, etc.), but will be familiar and free. And it doesn't need an extra SDK rolled into your app.
So, my general answer is that there's more than one professional beta-testing API/service that you could use, that they're generally very useful, quite easy to roll into your app, solve all the problems you're anticipating and more, and often have a free plan to get started. I'd recommend picking one of them rather than trying to roll your own solution.
If you want this only to be able to release your app in Alpha, and maybe later in beta, take a look at the android market again.

It boils down to the fact that you can have an Alpha-test, and a beta test, each with selected users. You can upload your app as normal, so you'll have updates via the market, but not everyone can download your app.
For the beta at least, you can select a community that is the source of your users, so all that are in that community could be testers.
This is the best method for testing I believe.

Here's the scenario i am trying to achieve:
Publish/have an app in the Android app store
However - i do not want it to be searchable through the android market search, etc.
The only way people can access the app is if i give them an explicit link to download
Is above possible? If so - how? All FAQs/instrucitons i have seen publish & make it searchable for the whole world - but i want it only accessible through #3 above.
Thanks.
Try this site https://www.push-link.com/, you can upload apk on your private account and only can be accessible thorough automatic generated link and QR code. This service contains user notification on new versions and bug reports.
Two things that are problematic with the link to an APK approach:
Some of the devices out there (I m only aware of the Motorola Atrix) don't have the "Unkown Sources" option, meaning that this won't work on them.
You loose the ability to auto update the app if you want.
I would recommend adding a login process where only your users will have access to the actual application. This way, you still have the Market advantages and only those people can activate the application.
The main disadvantage is that the application will be open to search in the Market, but as far as I know, this won't be a problem since people will immediately uninstall it since they won't be able to activate it.
In your case, what I do is, I dont upload the application to the Market and distribute it from my server.
I mean this is simple, sweet and it also saves my $25 for the market account...
Don't do this. Just publish the APK to your own website, then give the users the URL to the APK, they can download and install it directly. The only thing they'll need to do is ensure that Menu-Settings-Applications-Unknown sources is ticked.
