I am making an app that has two button that then open different apps I have made. This makes use of intents. The first one works fine with no issues, but the second app results in a crash and this error.

This is the line that throws an error when the button is pushed to go to the BmiCalculator module.
heightLabel = (TextView) findViewById(R.id.heightLabel);
To clear up some confusion, this is one app. The two apps the main page is linking to by the use of intents have been imported into Android Studio as modules.
I had two XML layouts both named activity_main. As such, one app was using another activity_main that it should have been. Once I renamed the XMl file and then updated the Java code, this resolved the issue.
