-- try to clean project and rebuild project.
From #Kael: A clean is performed via Build -> Clean Project or Build -> Rebuild Project.

Kindly follow these steps:
Goto
1>File
2>Settings
3>Build,Execution,Deployment
4>Instant Run
5>Uncheck (Enable Instant Run to hot swap code)
So this helped me.

In my situation Build Menu > Clean Project and Build Menu > Rebuild did NOT work. Instead I had to delete the build folder manually from the filesystem (using Finder on OSX, Explorer on Win).

Try to clean project and rebuild project from Build Menu > Clean Project and Build Menu > Rebuild
try restarting android studio or use android studio on different user

I had the same problem .. I solved my problem by deleting .gradle file on my project root and rebuilt my project again.

I had Execution failed for task ':app:generateDebugBuildConfig'. error, cleaning and rebuilding project was not working.
I added C:\Users\...\AppData\Local\Android\sdk\tools to my PATH Environment variable.
I closed android studio and vscode that I was using for edit project files. (This is very important)
I run the project and it worked fine.

Change this https://services.gradle.org/distributions/gradle-4.4-all.zip to this https://services.gradle.org/distributions/gradle-4.1-all.zip in grable-wrapper.prperties. And then re import the properties. and sync the project.

Android Studio on Mac OS X, Gradle complaining about org.bouncycastle.asn1.ASN1Primitive

Recently migrated (or still trying to) from Eclipse ADT to Android Studio, here's what Gradle says when I hit `Run' (full trace below):
* What went wrong:
Execution failed for task ':app:packageDebug'.
> class org.bouncycastle.asn1.ASN1Primitive overrides final method equals.(Ljava/lang/Object;)Z
I've seen: Android Studio Bouncy castle issue (newbie), Problems launching error in Android Studio when packageDebug at Max OS X and similar SO posts that all point out to a bouncy castle JAR (bcprov-jdk15on-1.48.jar) that should be removed from the classpath. However I have no such JAR file there and it, in fact, Gradle itself seems to download it because the only place where I found it was:
/Applications/Android Studio.app/Contents/gradle/m2repository/org/bouncycastle/bcprov-jdk15on/
Trying to delete the file there, Gradle complains that a referenced library is missing.
Just how do I fix this?

Android studio does not start the application on the external device(application does not get installed)

I am trying android studio for the first time.
I have connected external android device via USB (debugging device settings are done in android device). I click on run button with selection as USB device.
The Run console shows this
Waiting for device.
Target device: iball-3g_q1035-0123456789ABCDEF
Whereas my gradle console shows this

Android Studio Gradle :app:preDexDebug never finishes

I have an issue and despite of a lot of googling, i couldn't find any informations about it.
So I have Windows 7 and had Android Studio 1.1 RC Beta and after modifying my code regarding work with a database i got failure install_failed_dexopt
I tried to clean and then to rebuild my project and since that moment Gradle Executing Tasks never finishes if i run my project. I saw into the Gradle logs and here it is
Executing tasks:
[:app:assembleDebug]

I waited ~30 minutes and nothing after that.
If i try to stop it, it also never stops, i see only
Stopping - Gradle: Executing Tasks[:app:assembleDebug]
and nothing else
I tried to unistall Android Studio, installed also 1.0.1, I tried to run "hello world" application - is always the same. It would be great if someone have any idea about it, thank you!

So it seemed to be a problem with sdk. At first I didn't notice, that even if I install Android Studio and sdk into another folder path to sdk was always the same and it was something wrong with that sdk directorie.
