Default Activity not found

[winster]

Since there is no activity defined in the manifest, getting error in Android studio.

Error running app:
Default Activity not found

[tjohns]

Yes, this is correct. This is an input manager, not an activity.

You can get Android Studio not to complain by going to the "Edit Configurations" menu (tap "Shift" three times, type "Edit Configurations"), then change Launch Options > Launch to "Nothing".

I'll probably add a generic activity containing instructions, just to avoid any confusion.

I also got the same error; however, in my case it was straightforward since this error occurred in a fresh project and it turns out I have to add an intent inside activity tag to get rid of the error:

<activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>

@tjohns i agree with you that if we change that setting then app works fine but what if want to run the app without edit Edit Configuration ? I have checked this stack overflow question's answers to solve this issue in android studio 3.2
I have spend almost 5 hours and got the solution. I have copy that project and run in another system then its working fine, So just do following solution to fix this issue and it is work for me and i hope some one will get help with this.
Solution :

1. Delete the cash from your %Home%\.gradle\cash and sync project again.
2. Also check that is there any duplicate tag in your Manifest.

1. Delete the caches from your `%Home%\.gradle\caches` and sync project again.

that worked really well for me. I tried file>invalidate caches/restart and that did not work for me

I lost over 6 hours hunting down the problem. I even redownload gradle, restarted Android studio, Invalidated cache/restart to no vail. Until a sister pointed me to this wonderful thread.

This came to my rescue.

Make sure your application label and your activity label are not the same string resource when declared in the Android Manifest
