I am facing a strange behavior of Android Studio. When trying to run an app and the build fails the Run button becomes disabled. I resolve the issue but the run button doesn't changes state. So, I have to restart the IDE. Is there any solution? Below are the screenshots describing my situation. My os is Ubuntu and Android Studio version is 1.1.
On line 176 is that red writing after the semi colon suppose to be there? Try removing it

I updated to the new Android Studio version 4.0 and there's an irritating issue I am facing which
I believe is a result of instant run (or whatever the new name of this feature is). Basically on using the Android studio run/play button, the app does not launch on the device sometimes and erratically. It always installs but sometimes fails to launch.
I have had similar issues in the past and simply disabled instant run, however, in Android Studio 4.0 I can't see any option anywhere to disable it. I read somewhere that the feature name is changed but searching for that name also didn't yield any results.
How can I disable instant run in android studio 4.0?
I've faced the same issue and disabling parallel run option in the edit configuration window solved the issue for me.
"Apply Changes" has been introduced in replacement of instant run. Besides the Run green button in Android studio, there is apply change option in android studio 4.
I have just updated my Android Studio to 3.5 and I am starting to use the new "Apply Changes" feature. I can deploy my apps without problems using AVD, but when I use my smartphone (Galaxy S9+ with Oreo) the process keeps crashing and all the times I have to kill manually the app and click Start.
I've already tried to create a new project, kill all the apps, plug & unplug the USB cable and restart my device. I tried also Invalidate cache/restart and clean project.
This is the error that the IDE gives me:
E/zygote64: Bad JNI version passed to GetEnv: 805372416
E/studio.deploy: Error retrieving JVMTI function table.
Changes were not applied.

Thanks for your help
After contacting the Google Team they have opened a new issue, here's the link if you want to stay updated: https://issuetracker.google.com/issues/139942372
UPDATE: Google has marked this issue as fixed, I think that in the next update everything will be fine.
If this is happening with a plain project, my guess is that there is some incompatibility between your device and the "Apply Changes" feature in Android Studio 3.5.
This issue seems to match your symptoms. Keep an eye on it, and with luck this will get fixed in Android Studio 3.5.1, either by fixing the IDE or at least detecting that "Apply Changes" will not work and reacting better.
Last night, I clicked "run" button and Android Studio built my app.
But after completing the build task, it did not work on my device anymore.
How to fix that? Do I have to set the auto run option?
I checked the application installation on my device.
My issue is that "autorun on device" does not work.
Open the Gradle tab that is on the right side of the Android Studio UI.
Find the installDebug option, and the Run button will use that as the "last ran" command.
If you are otherwise unable to run the app, then you may have a compilation issue
I've installed Android Studio 2.3 rc1 and my app doesn't run. Only the Splash screen activity that I've setted up is shown, and then the app crashes.
The big problem is that the log is empty, shows only "Connected to process..." and "Application terminated".
How can I solve this? Is it normal for non-stable version of Android Studio (I'm a noob) or it's a problem of my app?
Edit 1: I've tried to create a new simple project but the result is the same. So maybe the problem is the IDE.
Edit 2 (partially solved): During operation on Edit 1, I've tried a code sample from My App, not an entirely new project, the problem was exactly in that code XD.
Now I've tried other projects and they work.
Edit 3 (solved): I'm really sorry, I think you can delete this thread. The logcat was not empty. I had exchanged the position of the logcat screen with the run one, and by force of habit, always clicked on it without reading the label that had changed. Forgive the fool.
Android studio allow you to run Stable, Beta and Canary builds at the same time. Try running your app on stable version to find out if this has something to do with the IDE or your app.
When you are running Beta/Canary builds it is always a good idea to keep a stable version in your computer as these releases are not always 100% stable.
The strangest thing happened overnight. I try to debug an app from Android Studio to Genymotion. I see Gradle build finishing, but the app is never deployed. Thereafter the debug button gets disabled. The same story occurs with the run button. And neither SHIFT+F9 nor SHIFT+F10 work. Has anyone faced this problem as well?
I am using Android Studio 1.5 RC1 and latest Genymotion
If the above solution doesn't work, just try re-installing Android Studio. And when installing, make sure HAXM is installed properly. Use this link for reference. I used to have the same issue too.
Go to Run > Edit Configurations... and setting like this:
