When I deploy my app to any Android device I get an old version of the app. I have factory reset the android phone on Kitkat 4.4.4 and have also tried installing on a newer android 5.0 device. I am always getting the same old version cached. When I debug with the ripple emulator I always get the newest changes with no issue.
I have tried adding 'preference name="useBrowserHistory" value="false"' to the config.xml in the solution with no luck. One notable change that has happened is I have moved to a new computer and I did not have this issue on the old one.
Any help would be greatly appreciated.
Have you tried to delete the bin and bld folders in your project before you deploy? It might be that for some reason your Android project is not being rebuilt. This should force it.
Try to use the option "Revoke USB debugging authorization" above "USB debugging" to update the authorization Keys in Developer Options in your Android Phone or Emulator.
I use Visual Studio 2015 with Xamarin and works for me.

I just upgraded my android studio to 4.1 version:
And tried to run some project on this emulator:
And for some reason, this specific emulator is crashing my android studio, I have noticed that I am getting an error:
After reading about the subject, I uninstalled "Riot Vanguard" but it did not solve my problem.
More info (and partially solving the problem ) can be found in "Update" at the bottom of the question.
In addition, moments after my android studio will get closed I will get a windows blue screen (happens every time).
I didn't have this problem earlier with android studio below 4.1 version, why is this happening?
Update (problem solved for others emulators)
I have run into the same problem on other emulators as well, but I could open those emulators so I could fix the problem:
Solution 1
According to most threads that I have run into, You will need to disable or uninstall "Riot Vanguard":
Open task manager, go to the startup tab, right click on Riot Vanguard, and press disable
Solution 2
If step 1 didn't fix the problem you may want to enable developer mode on your emulator.
For some reason with android studio 4.1 android studio could not find the emulator (It will tell you that there are "No connected devices") without enabling the developer mode
Before Android studio 4.1 version I didn't need to enable the developer mode to run projects on emulators and this is what solved the problem for other emulators for me.
BUT
Although I don't have any problems with other emulators at all I still can`t even open Pixel_3a_API_30c68 emulator without it crashing
How can I fix this problem on the specific emulator?
Update 2
The problem still occurs even After updating android studio to 4.1.1
Without having "Riot Vanguard" I also could not run any emulator in Android Studio since I upgraded to version 4.1. After some hours I finally found out what caused the problem (in my case):
"Android SDK Tools" have been replaced by other SDK tools (which ?) and is obsolete now. As soon as I UNINSTALLED "Android SDK Tools" the emulator worked again.
I would be interested to know if the java version makes a different. I moved from Windows to Linux because of problems running the emulator.
Linux worked great until I moved to Android Studio 4.1. So check java and it was version 11. Changed to java8 and it worked straight first time.
Seem to remember there was a setting in Android Studio to set the SDK which I think was version 8. But can no longer find this in settings in Studio 4.1.
Updating to the latest system image of the SDK helped me.
I am having an issue with Android Studio not connecting to any devices. This includes physical devices, as well as emulators. Everything was working, but I updated AS to the latest version, and now it is not working. The devices still show as connected when I use adb on the command line, so I am able to run commands through that. However, I can not run anything from Android Studio, or debug, or use logcat. What could possible be the issue where adb is connected to the devices, but Android Studio is not?
Even using the connection assistant shows that I have a pixel connected, but AS does not recognize it as an android device.
This is for Android Studio 3.6.2, updated recently: Directory 'platform-tools' contains a directory of the same name, and I made the hypothesis that this was a bug and that the lower dir should not the there. Using the Mac Finder, I copied all files and directories from the lower dir to the upper one, I closed and restarted Android Studio, and voila, the Run > Select Device... can see my tablet, and I could run the app on it.
I'm running on a mac with Yosemite. I tried running old versions of Android Studio that were laying around which was a waste of time. So I got drastic.
This is a really bad solution, but has allowed me to actually get back to work.
Completely uninstall Android Studio and the Android SDK (the sdk might have been over-kill, but I'll let someone else figure that out). If you like, here's a website that helps uninstall AS. https://nektony.com/how-to/uninstall-android-studio-on-mac
Re-install Android Studio using an older version. I used 3.5.2 because I liked that color of green better than the new one. The link to find it: https://developer.android.com/studio/archive (you'll have to agree to their terms before being able to even look at the list!).
Run the newly-installed AS. Connect your device (remember to turn dev-mode!)...voila!
Well, it worked for me. And I only wasted 1 day.
I am using a MACbook. For one specific emulator its always showing offline. The emulator has a nexus 5 skin and is a api 24 build. When i try another emulator its fine and works. i tried re-creating the emulator. when i run adb devices it says the "unauthorized".
I tried the following:
I went into the developer settings of the emulator and allowed usb debugging if to see if that would help but it did not. this happened after i updated android studio to 2.3. i also tried to wipe user data from emulator. What is going on here ?
UPDATE: THIS IS OCCURRing for my other emualtors above api 22 also . i had to switch to genymotion for now which seems to work fine and shows as online. it has something to do with updating android studio. after i re-installed studio and did not take the 2.3 update, the problem was resolved.
Don't know the exact issue but it appears there are some bugs/issues with the latest updates.
Personally I am seeing my tests fail when run by ./gradlew commands, but not when run via Android Studio IDE.
I experienced your offline issue as well, I found I could at least rectify this by running:
adb kill-server
adb devices

-- UPDATE --
After investigating this one a little more, I found there to be compatibility issues between Qt version 5.7.0 which the new emulator uses, and Ubuntu 14.04 and it's version of Qt. Whatever system you will be using, you will have some version of Qt installed.
I'm guessing this may be the cause/related to the issues you are experiencing.
I was successfully able to fix my system by downgrading the SDK tools from version 25.3.1 to 25.2.3. I don't get the speed improvements of the new emulator, but at least I can run my tests reliably.
Going to try resolve the issues between Qt versions, and will update this if I can get the new emulator to work correctly again.
I had the same problem. I solved it by turning on USB debugging after unlocking developer options of the emulator by clicking 7x on the build number.
I have updated my android studio to 2.2, Since then I get this strange issue when running the studio gives me error Instant Run requires that the platform corresponding to your target device (Android 1.0) is installed. I am using Note 4 on android 6.0.1. Why is this error happening ?
If you have connected your android device, unplug it then uninstall the current app. Then plug the usb back and click run. You good to go.
Am also facing similar issues since i downloaded the upgrade patch for android studio 2.2
i have noticed it happens when Android monitor says device offline Android device says offline yet connectet
The reason why the device goes offline and yet its connected properly i don't know yet. When i click download i get this error Package id platforms;android-1
I currently sole this temporarily by checking if android monitor says device offline, if yes i unplug the USB and plug it back in else it just runs fine
I had the same problems as you all and I solved it.
If you get an error like 'error Package id platforms;android-1 ' you must go to: Tools -> Android->SDK Manager, and thed to SDK Platforms. Make sure that 'Show Package Details' tab is checked (so that you can see all packages) and Android 1.1 package installed.
Otherwise just install it like all others packages. After you do this, restart Android Studio, unplug/plug phone. You will be asked then to conform something at your device, say ok and you fixet problem.
I got the same problem, but with an emulator.
So the answer of unplug/plug the device is not applicable to me.
I deleted my emulator and create a new one in Android Studio.
And, it's solved...
Connect to your computer as MTP. After this Android Studio will recognize your device and SKD could install for it.l
I've solved this by changing the USB cable. The one given by Samsung is useless.
I had the same problem but it solved after I approve the confirmation box for connecting the phone to the computer.
Running the android studio as sudo did the trick for me.
i got same problem , i have unplug my Device then uninstall the current app. Then plug the usb back and click run. i am good to go and my Problem
In this Video there is a Solution for Error running app: Instant Run requires 'Tools | Enable ADB integration' to be enabled. It worked for me to disable the instance run error messages.
In my case SDK location was incorrect.
I disabled Instant_Run option.
please check SDK version in local.properties file.
I currently have the latest version of Android Studio and I'm trying to deploy an app onto my phone running Android 5.0.1 Lollipop. After building, the terminal shows that the apk is being installed onto the phone and the status indicates that it is running. However, nothing shows up on my phone (no running applications and the app does not show up in the installed applications list). I've tried disabling auto-run in studio settings but it doesn't help. Any ideas why it's doing this? Also I reinstalled the adb driver just in case that was the cause. It might be helpful to note also that this happens even on the default template apps generated by studio.
try to turn off the Instant Run
File - Settings - Search Instant Run , unselect all the options
Hope this would help.
In my case the 'HMS Toolkit' (version 6.3.0.3003.AF) plugin, on Android Studio Chipmunk (version 2021.2.1), was causing this.
I've disabled it and it all started working again.
