I want to know why users delete my app. So, I what to know why users do it. Is it possible to ask the user why they deleted my app? API something like ACRA library.
It´s not!
When an Android-APP was uninstalled there is an INTENT coming up.
http://developer.android.com/reference/android/content/Intent.html#ACTION_PACKAGE_REMOVED
So every other App might be able to recognize your app beeing uninstalled but not your app itself.

I’m working on an app that can "disable" another apps for a limited time. In the first activity the user can choose which application he wants to disable, then my application needs to check if the chosen apps have been opened. If so, my app needs to detect it and show the “disabled app” activity of my app instead.
My problem is how my app can detect that the disabled app has been opened.
I looked for solutions and found this one and this one, but they were removed.
Thank you!
There is an API you can use to query events about apps (packages) but it requires an additional 'special access' permission . Have a look at UsageStatsManager
I find this question a couple places on the web, but never with a good answer. Let me be specific in the questions asked.
I want to build a custom Android ROM which only features one app. This app is not to interact with any hardware (per now). This app will be launched on the start up of the device. No locked-screen. The device will have to restart if the app malfunctions.
A resource told me that you can change the launcher app of the ROM.
-> Does this mean that the home screen, the one which displays all apps on our phones, is merely another app? If so, can you simply change the launcher app as it is stated here? What were to happen if this app fails?
If this is the case, it would solve the entire issue.
If not, how do you go about making this sort of project? It includes
Making an app on AOSP
Refuse users to leave the app or interact with anything else
Making this app part of the boot-up process
Remove locked screen
Make the app a dependency of the OS (to force shutdown if malfunction)
Thanks in advance for any replies
I just found Android have a topic about dedicated devices (formerly called corporate-owned single-use, or COSU) are a subset of company-owned devices that serve a specific purpose. maybe that can meet your requirement.
BTW, After into the sub-topic lock task mode that mentions about set DPC whitelist APPs and the device policy controller (DPC) needs setup by other steps.... FYR~
I have an idea for an app and after doing some research I couldn't find anything that would answer my question, what I want is for when a user touches their android phone off a tag, it auto downloads an app for them, kind of like a QR Code, but specifically nfc.
All help appreciated.
No app can be installed without user interaction. This is required because the user is in charge of the device and he has to manually allow an app to be installed, otherwise you have a great recipe for allowing malicious apps to find their way to your device undetected.
Best you can do is direct them to the play store page with your app, but it is up to the user to decide whether to install it or not.
I want to make an app that takes info/data from other apps that are already installed on my phone ( Android ). By example: Let's say I want to make an app that shows how many messages I sent to each person with my phone. Then I would like to get my app linked with the message app on my phone and count how many times I sent someone a message , get that data, and put it on my app.
When I search for this problem, one 'solution' I found was working with intents, but it's NOT that, by far as I know, you can use intents to share data between apps you created yourself. I want to be able to get data from apps that I did not make. HOW? Thanks already
You can't, otherwise it would be a security issue, think about a bank app... In Android all the apps are fisically separated into different directories.
You can access data only from apps that expose methods, like Intent.
I am using the BackupManager to backup SharedPreferences to the cloud. Now this works as expected when I use it on a single device and only perform a reinstall not a full uninstall. To do that I am clearing data which wipes prefs and than reinstalling the app from eclipse. If I first uninstall the app and after reinstall it the restore call reports no data to restore. The same happens when I install the app on another device.
From my understanding I would expect the data to be restored to any device regardless of the app being reinstalled or being a fresh install. Let me know if posting code will help but I figured that because it is working I might just have misunderstood what the service should be used for and how it works. I am trying to backup a users settings and possibly some information they enter into search fields. I would like this data to follow the user to a new device or if the user uninstalls the app and reinstalls at a later date. Please let me know if BackupManager is not the correct tool to accomplish this.
As I know from the words of Android Advocate:
Generally it seems that BackupManager is only reliable for backing
up app data that will later be restored on the same device if the app
is re-installed from the Play Store.
If you want to do backup syncing across multiple devices then you can try to use Google Drive API, not BackupManager, and that there is very useful session from Google I/O 2012 on the subject.
