PID: 7202 SIG: 9 Heres the part of the androidmanifest.xml file I belive it is talking about:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.testapp"> <application android:allowBackup="true" android:icon="@drawable/bolt_logo_2_bolt_square" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> Any help would be greatly appreciated, knowing me I’ve probably missed something stupid lol
Edit: changed the code sample as I misread it as activity_main.xml sorry
Edit 2: sorry completely misunderstood what was meant, however from that ive fixed it. simply removed the activity from the activity_main.xml file and it worked. Thanks a lot!
