        </intent-filter>
    </activity>
</application>

Did you try to re-import your project? Also, you can delete .gradle and .idea folders in your root folder. — Murtadha S., Oct 04 '18 at 07:05
Test case **`Clear-Rebuild-run`** or just use **`invalidate-cache- and restart-studio`** — AskNilesh, Oct 04 '18 at 07:06

None of the given solutions worked for me. The thing that worked for me was:

Exit Android Studio
Find AndroidStudio3.2 (or whatever your version is) folder
Go to AndroidStudio3.2 -> system -> caches
Delete that folder
Restart Android Studio

It will re-index your files and that thing will work

I solved the very same issue by doing this

Close Android Studio

deleting :

1 .android

2 .AndroidStudio

3 .gradle

from C:\Users\[your user name]

Start Android studio ( Will take some time to rebuild)

It worked for me by adding the default activity in the configuration, Following these steps:

1- Select Edit Configurations from the drop down next to run button.

2- Under launch options > Launch select Specified activity.

3- Another field "Activity" will appear select your default activity.

4- Click OK and sync project with gradle files and it should work.

Have you refactored it in anyway ? Trying doing :

Cleaned the Project
Deleted the Build directory
Restarted Android Studio
Rebuild the Project

For future visitors with similar problem, I am just posting this incase if this turns out to be same problem for you. I tried everything mentioned here and yet none of them worked. Error: Default Activity Not Found

I am using Android Studio Stable 3.2.1 version and project is in Kotlin. I cloned project again and opened project freshly again after several Invalidate caches/Restart but din't help. Finally this 1 helped -> upgrading kotlin version in root .gradle file..from 1.3.10 to 1.3.11

In root gradle file

buildscript {
    ext.kotlin_version = '1.3.11'
    ext.annotation_version = "27.1.1"
    repositories {
        google()
        maven { url 'https://maven.fabric.io/public' }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.0.2'
        classpath 'io.fabric.tools:gradle:1.+'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
