Detailed Description

A Flutter Activity that is based upon FragmentActivity.

FlutterFragmentActivity exists because there are some Android APIs in the ecosystem that only accept a FragmentActivity. If a FragmentActivity is not required, you should consider using a regular FlutterActivity instead, because FlutterActivity is considered to be the standard, canonical implementation of a Flutter Activity.

Member Function Documentation

◆ cleanUpFlutterEngine()

void io.flutter.embedding.android.FlutterFragmentActivity.cleanUpFlutterEngine ( @NonNull FlutterEngine flutterEngine )

inline

Hook for the host to cleanup references that were established in configureFlutterEngine(FlutterEngine) before the host is destroyed or detached.

This method is called in onDestroy().

Implements io.flutter.embedding.android.FlutterEngineConfigurator.

Definition at line 747 of file FlutterFragmentActivity.java.

                                                                         {
    // No-op. Hook for subclasses.
  }

◆ configureFlutterEngine()

void io.flutter.embedding.android.FlutterFragmentActivity.configureFlutterEngine ( @NonNull FlutterEngine flutterEngine )

inline

Hook for subclasses to easily configure a FlutterEngine.

This method is called after provideFlutterEngine(Context).

All plugins listed in the app's pubspec are registered in the base implementation of this method unless the FlutterEngine for this activity was externally created. To avoid the automatic plugin registration for implicitly created FlutterEngines, override this method without invoking super(). To keep automatic plugin registration and further configure the FlutterEngine, override this method, invoke super(), and then configure the FlutterEngine as desired.

Implements io.flutter.embedding.android.FlutterEngineConfigurator.

Definition at line 729 of file FlutterFragmentActivity.java.

                                                                           {
    if (flutterFragment != null && flutterFragment.isFlutterEngineInjected()) {
      // If the FlutterEngine was explicitly built and injected into this FlutterActivity, the
      // builder should explicitly decide whether to automatically register plugins via the
      // FlutterEngine's construction parameter or via the AndroidManifest metadata.
      return;
    }
 
    GeneratedPluginRegister.registerGeneratedPlugins(flutterEngine);
  }

◆ createDefaultIntent()

  }

◆ getAppBundlePath()

String io.flutter.embedding.android.FlutterFragmentActivity.getAppBundlePath ( )

inlineprotected

A custom path to the bundle that contains this Flutter app's resources, e.g., Dart code snapshots.

When this FlutterFragmentActivity is run by Flutter tooling and a data String is included in the launching Intent, that data String is interpreted as an app bundle path.

When otherwise unspecified, the value is null, which defaults to the app bundle path defined in io.flutter.embedding.engine.loader.FlutterLoader#findAppBundlePath().

Subclasses may override this method to return a custom app bundle path.

Definition at line 765 of file FlutterFragmentActivity.java.

                                      {
    // If this Activity was launched from tooling, and the incoming Intent contains
    // a custom app bundle path, return that path.
    // TODO(mattcarroll): determine if we should have an explicit FlutterTestActivity instead of
    // conflating.
    if (isDebuggable() && Intent.ACTION_RUN.equals(getIntent().getAction())) {

      }
    }
 
    return null;
  }

◆ getBackgroundMode()

BackgroundMode io.flutter.embedding.android.FlutterFragmentActivity.getBackgroundMode ( )

inlineprotected

The desired window background mode of this Activity, which defaults to BackgroundMode#opaque.

Definition at line 907 of file FlutterFragmentActivity.java.

                                               {
    if (getIntent().hasExtra(EXTRA_BACKGROUND_MODE)) {
      return BackgroundMode.valueOf(getIntent().getStringExtra(EXTRA_BACKGROUND_MODE));
    } else {
      return BackgroundMode.opaque;
    }
  }

◆ getCachedEngineGroupId()

String io.flutter.embedding.android.FlutterFragmentActivity.getCachedEngineGroupId ( )

inlineprotected

Definition at line 898 of file FlutterFragmentActivity.java.

                                            {

  }

◆ getCachedEngineId()

String io.flutter.embedding.android.FlutterFragmentActivity.getCachedEngineId ( )

inlineprotected

Definition at line 893 of file FlutterFragmentActivity.java.

                                       {
    return getIntent().getStringExtra(EXTRA_CACHED_ENGINE_ID);
  }

◆ getDartEntrypointArgs()

List< String > io.flutter.embedding.android.FlutterFragmentActivity.getDartEntrypointArgs ( )

inline

The Dart entrypoint arguments will be passed as a list of string to Dart's entrypoint function.

A value of null means do not pass any arguments to Dart's entrypoint function.

Subclasses may override this method to directly control the Dart entrypoint arguments.

Definition at line 817 of file FlutterFragmentActivity.java.

                                              {
    return (List<String>) getIntent().getSerializableExtra(EXTRA_DART_ENTRYPOINT_ARGS);
  }

◆ getDartEntrypointFunctionName()

String io.flutter.embedding.android.FlutterFragmentActivity.getDartEntrypointFunctionName ( )

inline

The Dart entrypoint that will be executed as soon as the Dart snapshot is loaded.

This preference can be controlled by setting a <meta-data> called FlutterActivityLaunchConfigs#DART_ENTRYPOINT_META_DATA_KEY within the Android manifest definition for this FlutterFragmentActivity.

Subclasses may override this method to directly control the Dart entrypoint.

Definition at line 798 of file FlutterFragmentActivity.java.

                                                {
    try {
      Bundle metaData = getMetaData();
      String desiredDartEntrypoint =
          metaData != null ? metaData.getString(DART_ENTRYPOINT_META_DATA_KEY) : null;
      return desiredDartEntrypoint != null ? desiredDartEntrypoint : DEFAULT_DART_ENTRYPOINT;
    } catch (PackageManager.NameNotFoundException e) {
      return DEFAULT_DART_ENTRYPOINT;
    }
  }

◆ getDartEntrypointLibraryUri()

String io.flutter.embedding.android.FlutterFragmentActivity.getDartEntrypointLibraryUri ( )

inline

The Dart library URI for the entrypoint that will be executed as soon as the Dart snapshot is loaded.

Example value: "package:foo/bar.dart"

This preference can be controlled by setting a <meta-data> called FlutterActivityLaunchConfigs#DART_ENTRYPOINT_URI_META_DATA_KEY within the Android manifest definition for this FlutterFragmentActivity.

A value of null means use the default root library.

Subclasses may override this method to directly control the Dart entrypoint uri.

Definition at line 836 of file FlutterFragmentActivity.java.

                                              {
    try {
      Bundle metaData = getMetaData();
      String desiredDartLibraryUri =
          metaData != null ? metaData.getString(DART_ENTRYPOINT_URI_META_DATA_KEY) : null;
      return desiredDartLibraryUri;
    } catch (PackageManager.NameNotFoundException e) {
      return null;
    }
  }

◆ getFlutterEngine()

FlutterEngine io.flutter.embedding.android.FlutterFragmentActivity.getFlutterEngine ( )

inlineprotected

Definition at line 652 of file FlutterFragmentActivity.java.

                                             {
    return flutterFragment.getFlutterEngine();
  }

◆ getInitialRoute()

String io.flutter.embedding.android.FlutterFragmentActivity.getInitialRoute ( )

inlineprotected

The initial route that a Flutter app will render upon loading and executing its Dart code.

This preference can be controlled with 2 methods:

Pass a boolean as FlutterActivityLaunchConfigs#EXTRA_INITIAL_ROUTE with the launching Intent, or
Set a <meta-data> called FlutterActivityLaunchConfigs#INITIAL_ROUTE_META_DATA_KEY for this Activity in the Android manifest.

If both preferences are set, the Intent preference takes priority.

The reason that a <meta-data> preference is supported is because this Activity might be the very first Activity launched, which means the developer won't have control over the incoming Intent.

Subclasses may override this method to directly control the initial route.

If this method returns null and the shouldHandleDeeplinking returns true, the initial route is derived from the Intent through the Intent.getData() instead.

Definition at line 871 of file FlutterFragmentActivity.java.

                                     {
    if (getIntent().hasExtra(EXTRA_INITIAL_ROUTE)) {
      return getIntent().getStringExtra(EXTRA_INITIAL_ROUTE);
    }

    return activityInfo.metaData;
  }

◆ getRenderMode()

RenderMode io.flutter.embedding.android.FlutterFragmentActivity.getRenderMode ( )

inlineprotected

Returns the desired RenderMode for the FlutterView displayed in this FlutterFragmentActivity.

That is, RenderMode#surface if FlutterFragmentActivity#getBackgroundMode() is BackgroundMode#opaque or RenderMode#texture otherwise.

Definition at line 923 of file FlutterFragmentActivity.java.

                                       {

boolean io.flutter.embedding.android.FlutterFragmentActivity.shouldAttachEngineToActivity ( )

inlineprotected

Hook for subclasses to control whether or not the FlutterFragment within this Activity automatically attaches its io.flutter.embedding.engine.FlutterEngine to this Activity.

For an explanation of why this control exists, see FlutterFragment.NewEngineFragmentBuilder#shouldAttachEngineToActivity().

This property is controlled with a protected method instead of an Intent argument because the only situation where changing this value would help, is a situation in which FlutterFragmentActivity is being subclassed to utilize a custom and/or cached FlutterEngine.

Defaults to true.

Definition at line 684 of file FlutterFragmentActivity.java.

◆ shouldHandleDeeplinking()

boolean io.flutter.embedding.android.FlutterFragmentActivity.shouldHandleDeeplinking ( )

inlineprotected

Whether to handle the deeplinking from the Intent automatically if the getInitialRoute returns null.

The default implementation looks <meta-data> called FlutterActivityLaunchConfigs#HANDLE_DEEPLINKING_META_DATA_KEY within the Android manifest definition for this FlutterFragmentActivity.
