Deep link launches Splash Activity, not main activity

Question

I followed this guide - Splash displays the right way to create a Splash screen for my Android application, so now I have 2 events (MainActivity and SplashActivity)

The problem is that Deep Links miss is behaving now, because instead of launching MainActivity they launch SplashActivity .

I do not want SplashActivity to SplashActivity displayed only after the application has started.

What can I do?

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(); } } 

MainActivity:

 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; } } 

Manifest file:

Edit: some people have indicated that I am using SplashActivity . It is true that the code is the next action. This is part of the react-native-navigation library that I use for on-screen navigation. Not sure if this will help, but here is the code:

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 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 js context loads */ public View createSplashLayout() { View view = new View(this); view.setBackgroundColor(Color.WHITE); return view; } } 

MainApplication.java The public MainApplication class extends the capabilities of NavigationApplication ReactInstanceHolder {

  @Override public boolean clearHostOnActivityDestroy() { return false; } @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); if (android.os.Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT_WATCH) { // only for KITKAT_WATCH and newer versions MultiDex.install(this); } } @Override public boolean isDebug() { // Make sure you are using BuildConfig from your own application return BuildConfig.DEBUG; } @Override public String getJSMainModuleName() { return "index"; } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); // Log.v(TAG, "onConfigChange"+newConfig); Intent intent = new Intent("onConfigurationChanged"); intent.putExtra("newConfig", newConfig); this.sendBroadcast(intent); } // 2. Override the getJSBundleFile method in order to let // the CodePush runtime determine where to get the JS // bundle location from on each app start @Override public String getJSBundleFile() { return CodePush.getJSBundleFile(); } @NonNull @Override public List<ReactPackage> createAdditionalReactPackages() { return Arrays.<ReactPackage>asList( new LinearGradientPackage(), new OrientationPackage(), new VectorIconsPackage(), new KeychainPackage(), new BackgroundTimerPackage(), new RNI18nPackage(), BugsnagReactNative.getPackage(), new BlurViewPackage(), new PickerViewPackage(), new ImagePickerPackage(), new RNFetchBlobPackage(), new MapsPackage(), new FIRMessagingPackage(), new RNAmplitudeSDKPackage(MainApplication.this), new RNVersionCheckPackage(), new RNCardIOPackage(), new AndroidWebViewPackage(), new WheelPackage() ); } @Override public void onCreate() { super.onCreate(); setActivityCallbacks(new ActivityCallbacks() { @Override public void onActivityCreated(Activity activity, Bundle savedInstanceState) { } @Override public void onActivityStarted(Activity activity) { } @Override public void onActivityResumed(Activity activity) { } @Override public void onActivityPaused(Activity activity) { } @Override public void onActivityStopped(Activity activity) { } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { } @Override public void onActivityDestroyed(Activity activity) { } // @Override // public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { // super.onRequestPermissionsResult(requestCode, permissions, grantResults); // } }); } @Override public ReactInstanceManager getReactInstanceManager() { return getReactNativeHost().getReactInstanceManager(); } } 

Any hints would be greatly appreciated, thanks!

Answer 1

Found the cause of the problem.

Actually it was a line of code on MainApplication.java :

 public boolean clearHostOnActivityDestroy() { return false; } 

when I changed this value to true , everything started working as intended.

This was a problem caused by my navigation library: https://github.com/wix/react-native-navigation

Answer 2

The android system looks at the manifest for the first tag:

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

Set MainActivity to use this tag instead of SplashActivity.

Always start MainActivity first, and in MainActivity onCreate, do all intent checks.

  //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 3

Example: your URL will look like https://example.com , and you have an intent filter in Android Manifest as shown below:

 <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> 

Use the URL Mapping Editor to easily add URL filters to your actions using Android application apps (Android Studio> Tools> Android Application Links).
