一个APK，多个应用模块

Question

I have a project setup with 4 modules that flows like this Module1 -> Module2 -> Module3 Module4

Module1 and Module4 are both entry points in to the app and need to have their own launch icons

Before I split the app in to modules this worked fine but when I split this into modules Modules 1 and 4 are are treated independent and I can either launch one or the other.

This is fine while developing the app but what I want at the end is to generate one APK that contains all modules and create 2 launcher icons when installed, but this isn't happening because it seems to generate 2 APKs

How do I need to organise this to generate one APK?

Answer 1

I figured it out.

It needs a bit more than just setting the intent filter so I thought I would explain it here in case anyone else is trying this.

Module1 is the application module, Module4 needs to be a library with just the bare definition for an activity.

Then in Module1 manifest you need to create an activity alias to Module4

The process is decribed well here..

Also because of this Module1 now has a dependency on Module4 too

Answer 2

In your Manifest file write this code at both entry point . it will generate two instance . for ex like this

 <activity
        android:name=".Activity.Your_module1_entry_activity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

and for your second module

 <activity
        android:name=".Activity.your_module2_entry_activity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
