深度链接启动启动活动,而不是主活动

react-native-navigation deep-linking android-manifest android java

SudoPlz · 技术社区 · 6 年前

我跟着 this guide - Splash screens the right way 要为我的Android应用程序创建启动屏幕,现在我有2个活动(MainActivity和SplashActivity)

问题是深层链接丢失现在表现得很好,因为没有启动 MainActivity 他们启动了 SplashActivity .

我不想要 飞溅活动 除非应用程序启动,否则不会显示。

我能做什么?

飞溅活动:

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 飞溅活动 . 这是真的,这是以下活动的代码。这是 react-native-navigation 我用于屏幕导航的库。不确定这是否有帮助,但下面是代码:

飞溅活动:

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
        NavigationApplication.instance.startReactContextOnceInBackgroundAndExecuteJS();
    }

    @Override
    protected void onPause() {
        super.onPause();
        isResumed = false;
    }

    private void setSplashLayout() {
        final int splashLayout = getSplashLayout();
        if (splashLayout > 0) {
            setContentView(splashLayout);
        } else {
            setContentView(createSplashLayout());
        }
    }

    /**
     * @return xml layout res id
     */
    @LayoutRes
    public int getSplashLayout() {
        return 0;
    }

    /**
     * @return the layout you would like to show while react's js context loads
     */
    public View createSplashLayout() {
        View view = new View(this);
        view.setBackgroundColor(Color.WHITE);
        return view;
    }
}

你的url应该是 https://example.com 您在Android清单中有如下意图过滤器:

<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,可通过Android应用程序链接(Android Studio>工具>Android应用程序链接)轻松将URL意图过滤器添加到您的活动中。

android系统查看第一个标记的清单,其中包含:

   <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,并在MainActivity onCreate中对意图执行任何检查。

    //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);
    }

找到导致问题的原因。

实际上是这行代码 MainApplication.java :

public boolean clearHostOnActivityDestroy() {
    return false;
}

当我将该值更改为真的 ,一切都开始按预期的方式工作。

这是我的导航库导致的问题: https://github.com/wix/react-native-navigation
