App does not launch through Android Studio

Issue

When I run my Android Studio project from the editor to my phone, nothing launches. Everything compiles fine, however no activity is started when it completes. I then have to open the application manually with my phone, and the newest code is indeed updated.

Here is a snippet from my Android Manifest:

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

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

What I have tried:

• Using a different physical device
• Using a virtual device
• Going into "Edit configurations" and selecting a default activity for launch

Solution

Ended up having the same problem as this post:

Android Studio 2.3 Update not opening app [Instant Run Service]

Solution is to disable instant run.
