Does anybody has the Idea of making an android app undeletable.I want to install selected apps on the system memory so that anyone having an access to my phone cannot delete those apps even after resetting the phone...
What I earlier saw was that the apps installed on the system memory cannot be changed or modified by ordinary users...I tried resetting my phone but saw some apps preinstalled from the company remained and all the apps that were downloaded from the play store were deleted..
The answer I got from searching the web was that I could make install an Android app to the system memory...does it make the app undeletable even after resetting or formatting the phone?
You can achieve this by making your application by Developing a Device Administration Application, follow this link http://developer.android.com/guide/topics/admin/device-admin.html.
you could only do this if you root your phone and place the apps inside system/apps.
However, if this is about your phone, why don't you use a password protector for apps, so nobody can access the app manager?
Removing a users choice to uninstall your app, goes against everything most programmers strive for. It's probably against the Google T&Cs also. And as already said, other than Malware or some dodgy virus attempt, there would be no practical (ethical) use for such an app, IMO.

I want to access the apk file of any app before installation.
In more details: in google play store when the user clicks on Install button I want my application to access the apk file of the application that the user wants to download, and analyze this apk file and be able to whether allow the installation or stop it.
is that possible and if so how to approach this
On Android this functionality was introduced in Android 4.2. It is usually used by anti-malware products like Google Play Protect is known as a "Package Verifier". There is a good blog post on it here.
The short answer is this has to be done as part of the phone manufacturing process as it is so critical to security. So the answer is it can be done, but if you write this code you will need to get a phone manufacturer to include your code as part of a phone system image.
Most third party anti-malware products instead rely on analyzing the APK after the install happens by listening to the package added notification.
Definitely not possible in the way that you want. Android's OS is pretty well locked down. You might be able to do something if the device was rooted but at that point you may as well write your own OS fork. You can attempt to do someting with https://developer.android.com/reference/android/content/Intent.html#ACTION_PACKAGE_ADDED broadcast but you will not be able to analyze the apk freely nor will you be able to stop the installation of it.
I port my android apps for making bb10 builds . Since now from bb10.2.1 update blackberry has introduced a new concept wherein apk's can be directly installed and can be installed in BB10 devices if the manage apps in settings menu of the phone is made ON. My question is that I wanna restrict my users from doing so and not installing the apk's into bb10 . And take download my app only from appworld.
Has anyone faced and has fixed this issue kindly tell me on how to solve the same.
Based on the Android behaviour, I don't think you can restrict users from doing so.
I haven't tried it on BlackBerry but from what you say, that option sounds analogue to the Unknown sources setting under Security settings on Android. If the user enables the installation of applications from unknown sources on their phone, there is now way to prevent the direct install of the apk (by adding something to your apk or any other way).
There is no way to restrict it to BlackBerry World only. If they get the APK, they can load it directly this way. There may be other ways around it though.
If, for example, your app is for sale and people are side loading a pirated copy, you could change your app to be free, and put some advanced functionality in your app behind an in-app purchase. That way they'll be forced to go through the storefront at some point to pay. This takes bigger changes to your app though, and the IAP implementation is likely different between BBW and GPlay.
You could also put in a version check: when your app launches, it checks a special file on your web server to see what the latest version of the app is. If they don't have the latest version, it doesn't let them use the app until they upgrade. This won't prevent side loading or piracy outright, but you can put out updates often enough to make side loading very annoying. When they are roadblocked and told to get the new version, you can link directly to the storefront to encourage them to get the latest version there.
Thirdly, and lastly, if you port your app to a BlackBerry 10 native, cascades, or WebWorks app, the app file is fully protected and can't be pirated or extracted from BlackBerry World (since the platform is secure). That will 100% protect you from piracy on BlackBerry 10.
I hope this helps!
I'm working at the IT-department of a rather large company, and we got Android phones for all of our employees. Every time someone quits or turn in their phone for any reason, we have to factory reset and then install all the required apps for our company, and this takes time.
I recently discovered that if you flash a custom rom, you can pick and choose what apps you want pre-installed in the ROM. This is good news for us and it got me thinking further.
So my question is, is there any way to customize the app data before flashing the ROM?
For example, we want our company's email app pre-installed with the correct user data already set up.
Look here http://forum.xda-developers.com/forumdisplay.php?f=613, theres some socalled 'rom kitchens' that let you remove or add apps from/ to roms and make some customizations.
I'm not exactly sure about having the users data already in the email application, but you need to decompile the ROM, place your company's applications in the /system/app/ folder and then recompile the ROM. This will keep you from having to install the applications manually.
I am developing a customer care android application. The client want that only the customer care application should be installed in the Android phone and we should prevent installation of other application. Is there any hack we can do to do that?
Is there any hack we can do to do that?
Fortunately, not from a standard SDK app -- the technical term for this would be "malware".
As the comments to your question indicate, you are welcome to root the device, remove the Google Play Store client (if it exists), and disable the ability to install from non-Play sources by adjusting the secure settings. However, I suspect that this will prevent you from updating your own app without rooting.
I'm writing an app and would like users to be able to download the apk and install it from my website. However, I would like the app to still be able to update through the market, is this possible?
I don't believe that it is possible.
You are better off to link them to the market from your website rather than hosting the APK file.
market://search?q=pname:your.package.name
That will open the market on the users phone. It is safer and easier than plugging in the phone and installing over USB.
As far as I know and tested, applications installed using .apk files, will be recognized from the android market. Some games though like Angry Birds, do not appear on my list of installed applications and unfortunately I can't find out why.
But for what is worth the following link will help you more.

This is not possible without apps like Titanium Backup. Titanium Backup can link apps to their market counter-parts but you cannot do it without an app like that (which requires Root).
As i know - it's not possible.
Even if you'll use the same package names and signing certificates.
