Deep link 启动 Splash Activity 而不是 Main Activity

Question

我按照 this guide - Splash screens the right way 为我的 Android 应用程序创建了启动画面，所以现在我有 2 个活动（MainActivity 和 SplashActivity）

问题是深层链接现在无法正常运行，因为它们没有启动 MainActivity，而是启动了 SplashActivity。

我不希望 SplashActivity 除了在应用程序启动时出现。

我能做什么？

SplashActivity:

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
        finish();
    }
}

主要活动：

public class MainActivity extends SplashActivity implements OnImagePickerPermissionsCallback {

    private PermissionListener listener;

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

    @Override
    public void setPermissionListener(PermissionListener listener)
    {
        this.listener = listener;
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults)
    {
        if (listener != null)
        {
            listener.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }


    @Override
    public View createSplashLayout() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Window window = getWindow();
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setStatusBarColor(getResources().getColor(R.color.navBarColor));
        }
        LinearLayout view = new LinearLayout(this);
//        view.setBackgroundColor(getResources().getColor(R.color.catalyst_redbox_background));
        view.setBackgroundResource(R.drawable.launch_screen_radius);
        return view;
    }
}

编辑：有人指出我正在使用 SplashActivity。没错，就是下面activity的代码。它是我用于屏幕导航的 react-native-navigation 库的一部分。不确定这是否有帮助，但这是代码：

SplashActivity:

public abstract class SplashActivity extends AppCompatActivity {
    public static boolean isResumed = false;

    public static void start(Activity activity) {
        Intent intent = activity.getPackageManager().getLaunchIntentForPackage(activity.getPackageName());
        if (intent == null) return;
        intent.setAction(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        activity.startActivity(intent);
    }

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setSplashLayout();
        IntentDataHandler.saveIntentData(getIntent());
    }

    @Override
    protected void onResume() {
        super.onResume();
        isResumed = true;

        if (NavigationApplication.instance.getReactGateway().hasStartedCreatingContext()) {
            if (CompatUtils.isSplashOpenedOverNavigationActivity(this, getIntent())) {
                finish();
                return;
            }
            NavigationApplication.instance.getEventEmitter().sendAppLaunchedEvent();
            if (NavigationApplication.instance.clearHostOnActivityDestroy()) {
                overridePendingTransition(0, 0);
                finish();
            }
            return;
        }

        if (ReactDevPermission.shouldAskPermission()) {
            ReactDevPermission.askPermission(this);
            return;
        }

        if (NavigationApplication.instance.isReactContextInitialized()) {
            NavigationApplication.instance.getEventEmitter().sendAppLaunchedEvent();
            return;
        }

        // TODO I'm starting to think this entire flow is incorrect and should be done in Application

Answer 1

android 系统查看第一个标签的清单：

   <category android:name="android.intent.category.LAUNCHER" />

将 MainActivity 设置为使用此标记而不是 SplashActivity。

始终首先启动 MainActivity，然后在您的 MainActivity onCreate 中对 Intent 执行任何检查。

    //replace getStringExtra with whatever you use to identify deeplink.
Boolean isDeepLink= getIntent().getStringExtra("").startsWith("mydeeplink://");

if(!isDeepLink)
    {
        Intent splashIntent=new Intent(this, SplashActivity.class);
        startActivity(splashIntent);
    }

Answer 2

找到导致问题的原因。

实际上是MainApplication.java上的这行代码：

public boolean clearHostOnActivityDestroy() {
    return false;
}

当我将该值更改为 true 时，一切都开始按照预期的方式工作。

这是我的导航库引起的问题：https://github.com/wix/react-native-navigation

Answer 3

例如：您的 url 将类似于 https://example.com 并且您在 Android 清单中具有意图过滤器，如下所示：

<activity
    android:name="com.droid.MainActivity"
    android:label="@string/app_name" >

    <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:host="example.com"
            android:scheme="https" />
    </intent-filter>
</activity>

使用 URL 映射 编辑器通过 Android 应用程序链接（Android Studio > 工具 > Android 应用程序链接）。
