Block mobile website to open my app android deeplink - Google Chrome

Question

I have supported deeplinks in my app

Answer 1

After lot of research I have solved it. You can use either way.

Handle in mobile website : So if you want to render your user to Chrome always when they are on your msite you can achieve this by redirecting all your urls to

• googlechrome://navigate?url=https://www.example.com
• intent://www.example.com/x#Intent;scheme=https;package=com.android.chrome;S.browser_fallback_url=https://www/example.com/x;action=android.intent.action.VIEW;end;

Handle in app

• Create single transparent activity to handle all your deeplinks

• Handle all the links using pathpattern = '.*'

• Redirect user back to Chrome for urls you do not want to handle in app.

AndroidManifest.xml

 <activity
            android:name=".DeepLinkActivity"
            android:noHistory="true"
            android:theme="@style/Theme.Transparent">
            <intent-filter android:autoVerify="true">
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="https" />
                <data android:scheme="http" />
                <data android:scheme="@string/SCHEMA" />
                <data android:host="@string/WEB_DOMAIN" />
                <data android:host="@string/WWW_WEB_DOMAIN" />
                <data android:pathPattern="/.*" />
            </intent-filter>
        </activity>

DeepLinkActivity

@Override
protected void onCreate(Bundle bundle) {
    super.onCreate(bundle);
    try {
        if (Intent.ACTION_VIEW.equals(getIntent().getAction())) {
            Uri uri = getIntent().getData();
            if (uri == null) throw new IllegalArgumentException("Uri can not be null");
            Intent intent = null;
            if (getString(R.string.SCHEMA).equals(uri.getScheme()) || uri.toString().matches(Links.REGEX)) {
                intent = linkIntent(uri);
            }
            if (intent == null) SystemUtil.launchUrlInDefaultBrowser(uri, this); else startActivity(intent);

        }
    } catch (IllegalArgumentException e) {
        Toast.makeText(this, R.string.can_not_open_url, Toast.LENGTH_SHORT).show();
    } catch (Exception e) {
        Toast.makeText(this, R.string.can_not_open_url, Toast.LENGTH_SHORT).show();
    } finally {
        finish();
    }
}

 /**
