If you using Context as parameter of function try this solution:
public class MyActivity extends Activity {
// bla bla bla .......
//error
myFc( getapplicationcontext());
// OK
myFc(MyActivity.this);
No executable code found at line ....
Try one from this solution:
1.) uninstall app from test device, try to debugg app
or
2.) open module gradle file and set minifyEnabled to false in debug condition
