Somehow your AndroidManifest get corrupted. AndroidManifest should contain root application details and other project settings like as follows. Please try again
by creating new project.
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Thanks to the comment of jaumard. If the Sync project with Gradle files
it's not visible you have to open the Gradle panel and click sync icon on top the toolbar.
