How to call an Android Activity using a URL Scheme

First, modify AndroidManifest.xml in the called (Destination) app as follows.

<activity 
    android:name=".BkCalculatorActivity" 
    android:label="@string/title_activity_calc">
    <intent-filter>
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.BROWSABLE"/>
        <data android:scheme="bk" android:host="calc"/>
    </intent-filter>
</activity>

The important parts are android:scheme and android:host. Converted to a URI, the example above becomes:

bk://calc?

Next, add code to the corresponding Activity.onCreate() of the called app so it can receive the URI data.

Uri data = getIntent().getData();
if (data != null) {
    String get_op1 = data.getQueryParameter("op1");
    String get_op2 = data.getQueryParameter("op2");
}

Converted to a URI, the example above becomes:

bk://calc?op1=100&op2=200

Finally, the calling side builds the Intent as follows.

Uri uri = Uri.parse("bk://calc?op1=100&op2=200");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
intent.setAction(Intent.ACTION_VIEW);
startActivity(intent);
