来自Modul的Android Studio Start Activity

Question

I have created an *.aar File from a Android Studio project. This file I have successfully imported to an another Android Studio project file. Now I want start the activity from the included libraries. But i am hanging and I try hour to hour...

In wich file I have to include the statement like this?

 public void button_to_start_the_activity(View view)
{
    Intent intent = new Intent(StartActivity.this, MainActivity.class);
    startActivity(intent);
}

Should I implement this in the modul java file or in the application java file? (Please check this out, I have not found a activity java file in my module :-/ glglgl) Steps bevor, i have created a new activity in my main-project and i was able to start the activity without trouble.

Okay... Next question:

In the Main Manifest,...what to hell I shout declare in android:name"....?...." like this:

<activity
        android:name="....??????...."
        android:label="DLC"
        android:screenOrientation="portrait"
        android:theme="@style/Theme.AppCompat.NoActionBar">
    </activity>

Maybe, or for sure, simple question... But i try to learn a little bit AS since a week... For your understanding, i will try to explain my project with simple words....:

Try to merge two app projects in one app!

I have created a app, then i have created an another app. Now i want to merge. Simple startpage (allready exist) with the function to call the both activitys... :-/

Answer 1

My final solution to start a modul activity in the main app (For poeple with less experience like me)

1. Create in Android Studio a modul from the existing app
2. Open Main-Project an insert the new modul (File-->New-->Import Modul)
3. Right click on project folder. Search App (left side), then dependencies (right side) --> Add new from modul --> Add your modul
4. Check your build.cradle (Main-App) for compile project(':yourmodul')

5. Add this in your activity (from the Main-App)

     public class StartActivity extends AppCompatActivity { public void gotocalc(View view) { Intent intent = new Intent(StartActivity.this, YourModulClass.class); startActivity(intent); } 

6. gotocalc is for start with a button android:onClick="gotocalc" set in your layout.xml in the Main App.

7. Clean, Rebuild
