feat(android): change app icons at runtime

[m1ga]

Summary

Android can change activity icons during runtime to predefined <activity-alias> nodes. We can add those into tiapp.xml.

This PR will add a method to switch from one to another alias and makes a change to the build script to not add the default LAUNCHER intent if there are alias nodes.

Test

• Create an app with the name test and add this to the <application> node:

<activity-alias android:enabled="true" android:name=".default" android:targetActivity=".TestActivity" android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
</activity-alias>
<activity-alias android:icon="@mipmap/ic_launcher" android:name=".red" android:enabled="false" android:targetActivity=".TestActivity" android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
</activity-alias>

• use icon.kitchen and download the default icon.
• put the file res content into app/platform/android/
• run this app code

var win = Ti.UI.createWindow({
	layout: "vertical"
});

var btn1 = Ti.UI.createButton({
	title: "switch to red"
});
var btn2 = Ti.UI.createButton({
	title: "switch to default"
});
var btn3 = Ti.UI.createButton({
	title: "switch broken"
});

btn1.addEventListener("click", function() {
	Ti.App.Android.changeIcon({
		from: "default",
		to: "red"
	});
});
btn2.addEventListener("click", function() {
	Ti.App.Android.changeIcon({
		from: "red",
		to: "default"
	});
});
btn3.addEventListener("click", function() {
	Ti.App.Android.changeIcon({
		from: "default"
	});
});

win.add([btn1, btn2, btn3]);
win.open();
