Android emulator is not asking for any permission while running an application which uses protective functions like dialing a number etc. Is the user consent asked only while running on a mobile and not on emulator?
permission is asked on install time, once the app is installed, it will use all the functionality of phone that was asked on install time.
So on Emulator, you just hit the run button and it installs automatically, that's why you are thinking it is not asking permission.
if you go into Settings->Applications->YourApp
you will see the details of the permission your app will use.
Update for newer emulator versions where the Settings app can't be found on the launch screen anymore: Open the notifications by swiping from the top of the screen to the bottom, do it again to enlarge the quickstarter for bluetooth, flashlight etc. On the bottom-right you will find a gearwheel to open the Android settings.

According to the documentations, an Instant App is downloaded via Google Play and launched on the fly. It is not installed but is rather cached in the Android system. As a developer and user, I would like to validate this behaviour.
I have tried running Clash Royale by hitting the "Try now" - that is when a splash screen is shown with a progress bar (assuming that's when the feature APK is downloaded?) and it launches soon. On exit, there is no application icon which is expected.
In the device storage I looked for trace of the APK but with no success. Do I need ROOT permissions to see this? Is there a way to inspect and verify?
There is still an APK installed.
For O+ devices, run adb shell pm path com.supercell.clashroyale after TRY NOW
And you'll see:
package:/data/app/com.supercell.clashroyale-CUaYOumzCbUDNAdv1MRtRg==/base.apk
package:/data/app/com.supercell.clashroyale-CUaYOumzCbUDNAdv1MRtRg==/split_split_2_tutorial_battles.apk
Do it again after INSTALL (for comparison), and you'll see:
package:/data/app/com.supercell.clashroyale-0Dn0s6yq6WqGCRZ9ETT8bA==/base.apk
package:/data/app/com.supercell.clashroyale-0Dn0s6yq6WqGCRZ9ETT8bA==/split_config.arm64_v8a.apk
package:/data/app/com.supercell.clashroyale-0Dn0s6yq6WqGCRZ9ETT8bA==/split_config.en.apk
package:/data/app/com.supercell.clashroyale-0Dn0s6yq6WqGCRZ9ETT8bA==/split_config.xxxhdpi.apk
(For pre-O devices, the first part won't work, but I don't know any other cmd that will do the same)
You can navigate to Settings -> Apps, and see instant apps there. The App Icon will have Lightning bolt sub-icon at least it looks like that on Samsung Android 12.
We have a project we need to complete at work, however the coding is done and the app works.
What I need to know, how do I take an Android tablet and change the OS that when the device is turned on the device must open up with a logo when started up, to say (ABC with the logo) and then the application we have designed should automatically open up and start running the operation.
In the same sentence, all apps should be blocked out and only the one app should be opened and should work, with internet connectivity.
There are a few different options,
1) Google Dedicated Device
2) Fully Managed Device
3) mason
4) SureLock for Android
After adding a certain website to homescreen through Chrome for Android, I'm looking for a way to autorun that homescreen app as the device boots up. I found a few apps in the Google Play store that offer that behaviour but they don't list Chrome homescreen apps as possible to autorun on boot.
Any solution, anyone?
Unfortunately, there is no solution right now. Chrome homescreen apps work slightly differently from regular apps. Please read here for the full details: https://developer.chrome.com/multidevice/android/installtohomescreen
Specifically, Google developers have mentioned that Android can not detect Chrome homescreen apps as installed.
Do not prompt the user to add your app to the homescreen. There is no
way to detect if the app is running installed or not.
So by extension, you are not able to run them at startup.
Running homescreen apps on device boot up might be tricky since Android cannot detect them as installed, but here is a workaround you might be interested in:
Install AutoStart - No root on your Android device
In the app, Set "Auto startup" to ON
Add Chrome to the Applications list
In Chrome, add the page you wish to launch as the browser start page
Optional - Install a secondary browser and repeat the steps above in order to avoid interfering with the start screen of your regular browser
Optional - Install an app like Fulscrn Free or similar and add your browser to the list of apps that run in full screen mode.
This way, every time you boot up the device, a browser will launch with the page you designate, almost as if it is launching the homescreen app.
Here is what I did:
Installed Tasker and AutoInput . They are paid though.
In Tasker, add a profile for "On device boot" and an action from Plugins->AutoInput.
Follow the instructions in AutoInput to create an action that simulates a press on the web app's icon on the homescreen.
I placed my icon on the default home screen, otherwise you might need to add a swipe action first to get to the proper screen.
I want to build an app that would remotely install other apps on controlled tablets.
I know from the Android SDK documentation that you cannot install an APK programatically without user interaction, and rightfully so!
However, it looks like Tab Pilot http://www.tabpilot.com/ does this in background.
Any idea on how they do it? Apparently, the tablet needs not be rooted.
Just that, I like to know is always all the preinstalled apps are with the uninstall button disable in Android.
If I am reading your question correctly, some of the pre-installed apps can't be uninstalled without rooting your phone using cyanogenmod or rooting your phone.
Some pre-installed applications can be uninstalled. For example in Android 4 (ICS) you can go to Settings -> Apps and select the "All" tab. There you can uninstall some of the preinstalled software.
Root the phone, put the APK into the /system/app folder and then unroot the phone. This is possible on a Droid 4 at least in theory. Not sure about other hardware models. If you can root and unroot the phones it should work.
This depends on the Device manufacturer. They have the possibility to install the app in any way they like before they freeze the image and flash it to the hardware in the factory.
For example some of the Branded apps might be installed under system privileges, but some of the more "friendly recommendation" apps might be free to uninstall.
From what i understand in ics apps in usolder can be uninsfreeled, apps in system folder instead of uninstall the button reads disable. Except for only s slight few only, these apps are reQuired by the os for the user to be able to"enable" a disable App, so i think i the app needs to be signed by the room cooker our needs top have a intent in the manifest like a launcher or home app (since if you disable your home launcher you bricked your phone, so you can't disable it, but if you give your app a intent label of copied from the Android source launcher then the phone will think it's a launcher, and not let you disable it, you will prob have to set the home launcher back to be default or Android will ask you witch launcher too use Every time user hits the home button, i was looking for the same answer found this page
Android 4.0 Api to Disable Apk Witch gave me the idea, currently thus reply is closest I've come to impinging the idea, i well be trying it soon, if you beat me to it, let me know tour results, and i well do the same.
And to install a app in /system/app a uninstall.zip won't do it, you need too root the phone, install the app, xfer it to system (i use system/app mover available in the play store free, the too secure ot Unindtsll app mover, and unroot, any way good luck.
P.s. I'm Not a Dev, i just understand the format format of the app language, and can c effectivly search for info, so please no code questions. i can't answer them, but google can.
