There is something that bothers me in android studio which is the way Logcat keeps showing some errors that have been fixed. Every time I run the emulator they keep appearing again. Although I fixed them as I said. The app doesn't crash but I just don't want them to show up.
Any idea how to resolve this issue?
It's because of the Instants run. Android studio is caching some of your code base for faster building and deployment, its much better if you do a build and install every time
To disable it go to "File -> Settings -> Build, Execution, Deployement -> Instant Run"

I saw a similar question but none of the answers actually tell you how to disable it, just give workarounds for the issue. I want to totally disable instant run, how can I do that?
The issue I have is that no matter what I do, use the run button, the debug button, the apply changes button, clean, etc, any code I just wrote won't run until I uninstall the app on the phone, if I don't do that all I see is the old code running. I'm guessing instant run is the issue since I always get the message that says App restart successful without requiring re-install.
From android studio 3.5 and above you cant disable it but if your running an earlier version: Go to Android Studio Settings or Preferences (for MAC) -> Build,Execution,Deployment -> Instant Run. Then deselect the "Enable Instant Run" checkbox at the top.
My android project has over 30 build flavors and I started seeing the slowdown. Android Studio just keeps freezing whenever I type a character or add a new line.
Filed a bug with Google but haven't heard back.
Has anyone run into this issue before?
Any help will be very appreciated.
Have you tried disabling Instant Run?
I would need more info on your config but it sounds like you probably have Instant Run enabled. The larger and more complex your project becomes, the higher the impact on IDE performance.
If you haven’t tried already, it’s worth a shot:
Android Studio -> Preferences -> Build, Execution, Deployment -> Instant Run
You may need to uninstall Android Studio. After a while it starts to present these freezes kind of without explanation. Whenever I face this type of problem in the IDE I reinstall it and it returns to normal.
Exactly my problem, if I have small change in app about display UI (modify activity code or resource layout), Android studio build very fast and then run my app in emulator without kill "previous version" process (running in emulator), sometime it's run and display correct, but sometime it doesn't run correct what I want, I must kill process manual and rebuild project, it takes a lot of time, and makes me confused because I don't know where go wrong,
I thought this is my bug.
It happen recently when I update Android studio, I think this feature is very powerful and helpful, application mustn't rerun from the beginning whenever build new version.
But how to enabled/disabled "fast build", sometime I want Android studio build my project normally.
You have 2 solution:
1)You can also disable Instant Run from Settings > Build,Execution,Deployment > Instant Run - and disable it
2)Clean Project when studio doesn't build properly
Press the stop button before running the app and then run the app so dialog will be displayed to choose the emulator.
I download the latest Android Studio 2.0 from Android Develop Website.
But when I change a line of code and use the "instant run", instead of updating the changes, it prompt me "no changes to deploy".
This will happen on code changes and XML changes.
But when I restart Android Studio, things will works fine for once or twice and then "no changes to deploy" Come again!
I used my old SDK on Android Studio older version.
JDK is 1.7.0
Windows7 64
So, is anyone has this same bug?
A lot of people are having this issue as Instant Run is still quite buggy. The best thing to do would be to disable Instant Run entirely by Preferences > Build, Execution, Deployment > Instant Run > Enable Instant Run
Solved by rebuilding Project (menu Build -> Rebuild project)
This sounds like a bug. It would be super helpful to our team if you can report the bug with specific repro steps so we can investigate. Without your help, it's going to be very difficult for us to track down these problems. We want Instant Run to work for you.
You can file a bug at this link: https://code.google.com/p/android/issues/entry?template=Android%20Studio%20Instant%20Run%20Bug
Also having this issue with Android Studio 2.1. Turning off Instant Run seems to have fixed it, which is unfortunate, but I was wasting more time failing to understand why old code was being run than Instant Run was saving me! Running Ubuntu, so agree not just a Windows bug.
Run TAB next to anroid-monitor, sometimes it shows, no changes to deploy mean changes in code has not been added to your app(this bug has been resolved to a great extent).
Sometimes it runs the new app and when you restart your app it shows the old one(this bug has been resolved, officially declared on android site ).
Solution :
Disable instant run under your project settings(you can face some error while gradle build if you switch from instant-Run to normal one then Try clean option or if still there's an error then you can delete those files at the path shown by the error)
Try to use the latest studio release which has totally improved
instant-run.
Not a solution but as a better workaround I'd prefer to:
Press "Recent Apps"
Simply close my app from the list
Run the app again
This takes less time than Clean and Rebuild.
Update:
Rerun the app also works:
When Instant Run does not works correctly:
As far as I realized, Instant Run works properly when I change my views ids otherwise it does't recognise changes in xml and gives me "No changes to deploy"
I also used clean and rerun app or Cntrl+F5 this fix my problem
I have been quite interested in developing an application for my Android device. I downloaded the all the required tools for VS2010 following this guide - http://mono-android.net/Installation/Visual_Studio and everything went pretty smoothly.
Now, the first time I ran the default application and it copied everything to the emulator, it ran perfectly. If I make a simple change to the application and hit F5 to redeploy - it starts the app, but it seems to have the old version on there still and doesn't show my changes. I've cleaned the solution and rebuilt the application, so I don't think its that. I've also completely changed the code (just in case it was something I was doing wrong), but that didn't work either. Oh and the build also succeeds!
Now the Emulator seems a bit flaky and slow...but is it something that I am doing? Is there somewhere I need to clear before hitting F5?
When it is doing the deploy, does it say "Uninstalling the previous version"?
Another thing to try is to manually remove the app from the emulator (Settings -> Applications -> Manage Applications -> -> Uninstall. Then deploy again and see if the new version is copying. This should narrow down if it's a deployment issue or a build issue.
