That's it, I'm trying to create an options menu with pictures (1 of basketball and 1 of butterfly) when you click on the item.

If you need the whole ZIP, here it is: Download the ZIP file

Thanks in advance!:)

CodePudding user response：

The problem is in your butterfly.png & basketball.png placed wrong directory.

Just move those image drawable-v24 to drawable

CodePudding user response：

The answer mentioned by Ganesh MB is correct.But I noticed one more issue.It is in your manifest.I see that the secondActivity does no have exported line in it.

So,replace

<activity android:name=".SecondScreenActivity"></activity>

in your manifest to

<activity android:name=".SecondScreenActivity"
    android:exported="true"/>
