Can't open Activity from other module

Question

I've added a reference to a new module and try to open an Activity from it. It throws an Exception that says:

android.content.ActivityNotFoundException: Unable to find explicit activity class{
com.giljulio.imagepicker.ui/com.giljulio.imagepicker.ui.ImagePickerActivity };

have you declared this activity in your AndroidManifest.xml?

Do I need to add anything else beside reference the new module?

Answer 1

You have to define in gradle dependencies(in module where you want to call another module activity):

dependencies{
     ...
     compile project(':yourModuleName')
     ...
}

After adding this sync the gradle and now can you use the activity in the module.

User like this. This will help you

Intent intent = null;
try {
    intent = new Intent(this, 
       Class.forName("ir.test.testlibary1.HelloWorldActivity"));
    startActivity(intent);
} catch (ClassNotFoundException e) {
    e.printStackTrace();
}
