Chrome自定义标签 - 意图未被触发(安卓)

5

我正在将PayPal集成到我的Android应用程序中,我被建议使用Chrome自定义选项卡,但似乎无法触发意图。

我认为我已经在AndroidManifest.xml中正确设置了意图。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.rhiannon.chromecustomtabs">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity android:name=".CompletePayPalPaymentActivity">
            <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="Test"
                android:host="com.Test.TestApp.PayPalReturn"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

我可以在我的Fragment类中成功启动Google Chrome标签(其中我有两个按钮:

  • 一个按钮将在Chrome自定义选项卡中启动www.google.co.uk
  • 一个按钮启动我的自定义网页(托管在本地主机上),当用户单击按钮/链接时,它将抛出重定向

请参见下面的代码片段:

public class MainFragment extends Fragment implements CustomTabsSceneHelper.ConnectionCallback {

    public enum CustomTabsAction {
        GOOGLE ("Open Google", "http://google.co.uk"),
        REDIRECT ("Open Redirect", "http://{mylocalhost_ip}/~Rhiannon/example1/test.html");

        private final String mActionDescription;
        private final String mActionUrl;

        CustomTabsAction (
                final String actionDescription,
                final String actionUrl) {

            mActionDescription = actionDescription;
            mActionUrl = actionUrl;
        }

        public String actionDescription () {
            return mActionDescription;
        }

        public String actionUrl () {
            return mActionUrl;
        }
    }

    private CustomTabsSceneHelper mCustomTabsSceneHelper;
    private CustomTabsAction mCurrentAction;


    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mCustomTabsSceneHelper = new CustomTabsSceneHelper();
        mCustomTabsSceneHelper.setConnectionCallback(this);
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onCreateView(inflater, container, savedInstanceState);

        View view = inflater.inflate(R.layout.fragment_main, container, false);
        Button buttonGoogle = (Button) view.findViewById(R.id.button_google);
        buttonGoogle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                open(CustomTabsAction.GOOGLE);
            }
        });

        Button buttonRedirect = (Button) view.findViewById(R.id.button_redirect);
        buttonRedirect.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                open(CustomTabsAction.REDIRECT);
            }
        });

        return view;
    }

    private void open(CustomTabsAction action) {
        final Activity scene = getActivity ();
        mCurrentAction = action;

        CustomTabsSceneHelper.openCustomTab(
                scene,
                getCustomTabIntent(scene, mCustomTabsSceneHelper.occupySession()).build(),
                Uri.parse(action.actionUrl())
        );
    }

    public static CustomTabsIntent.Builder getCustomTabIntent(
            @NonNull Context context,
            @Nullable CustomTabsSession session) {

        // Construct our intent via builder
        final CustomTabsIntent.Builder intentBuilder = new CustomTabsIntent.Builder (session);
        // Toolbar color
        intentBuilder.setToolbarColor(Color.GREEN);
        // Show title
        intentBuilder.setShowTitle(true);
        // Allow hiding for toolbar
        intentBuilder.enableUrlBarHiding();

        return intentBuilder;
    }

    @Override
    public void onCustomTabsConnected() {
        Log.i("MainFragment", "Custom Tabs > CONNECTED");
        if(mCurrentAction != null){
            mCustomTabsSceneHelper.mayLaunchUrl(Uri.parse(mCurrentAction.actionUrl()), null, null);
        }
    }

    @Override
    public void onCustomTabsDisconnected() {
        Log.i("MainFragment", "Custom Tabs > DISCONNECTED");
    }

    @Override
    public void onStart() {
        super.onStart();
        mCustomTabsSceneHelper.bindCustomTabsService(getActivity());
    }

    @Override
    public void onStop() {
        mCustomTabsSceneHelper.unbindCustomTabsService(getActivity());
        super.onStop();
    }

    @Override
    public void onDestroy() {
        mCustomTabsSceneHelper.setConnectionCallback(null);
        super.onDestroy();
    }

}

我现在有一个自定义的网页:

然后我有我的自定义网页:

<!DOCTYPE html>
<html>
<head>
    <title>PayPal Test Redirect</title>
    <script type="text/javascript">
        function RedirectSuccess(){
            window.location="Test://com.Test.TestApp.PayPalReturn://return";
        }

        function RedirectCancel(){
            window.location="Test://com.Test.TestApp.PayPalReturn://cancel";
        }
</script>
</head>
<body>
<a href="Test://com.Test.TestApp.PayPalReturn://return">Success</a>
<a href="Test://com.Test.TestApp.PayPalReturn://cancel">Cancel</a>

<input type="button" onclick="RedirectSuccess();" name="ok" value="Success"  />
<input type="button" onclick="RedirectCancel();" name="ok" value="Cancel"  />
</body>
</html>

我希望当用户在Chrome自定义标签页上点击链接/按钮时,能够重定向回应用程序,但我似乎无法使此功能正常工作。
public class CompletePayPalPaymentActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_complete_paypal);

        List<String> params = getIntent().getData().getPathSegments();
        if(params.get(0).equals("return")){
            Log.i("CompletePP", "PayPal Payment Success");
        }else{
            Log.i("CompletePP", "PayPal Payment Cancelled");
        }
    }
} 

非常感谢你的帮助!

有任何问题,我们将不遗余力地提供支持。

对于其他试图将http://localhost:8200用作其授权redirectUrl的人,您不能在Chrome自定义标签中使用localhost... 您需要定义自己的自定义URL方案。 如果您只是Android开发人员,则可能需要让后端开发人员在其端包含此更改。 - Sakiboy

我认为您的方案和主机混淆了。自定义方案URI不包含主机!因此,请尝试使用以下内容:

AndroidManifest.xml

    <activity android:name=".CompletePayPalPaymentActivity">
        <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="com.Test.TestApp.PayPalReturn"/>
        </intent-filter>
    </activity>

那么你HTML中的链接应该是:

<a href="com.Test.TestApp.PayPalReturn:/cancel">Cancel</a>

如果需要一个工作示例,请查看AppAuth for Android,它展示了如何使用Chrome自定义标签执行OAuth流程(到Google的OAuth服务器),包括从返回意图中解析数据。这是来自该演示的AndroidManifest.xml
