workaround for shareactionprovider leak

    private static Method activityChooserGetMethod = null;

    public static void fix(Context context, ShareActionProvider actionProvider) throws ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException {
        actionProvider.setOnShareTargetSelectedListener(new ShareActionProvider.OnShareTargetSelectedListener() {
            @Override
            public boolean onShareTargetSelected(ShareActionProvider source, Intent intent) {
                return false;
            }
        });
        ActivityChooserModel dataModel = ActivityChooserModel.get(context, ShareActionProvider.DEFAULT_SHARE_HISTORY_FILE_NAME);
        dataModel.setOnChooseActivityListener(new ActivityChooserModel.OnChooseActivityListener() {
            @Override
            public boolean onChooseActivity(ActivityChooserModel host, Intent intent) {
                return false;
            }
        });
        fixInternalClass(context);
    }

    private static void fixInternalClass(Context context) throws ClassNotFoundException, NoSuchMethodException, InvocationTargetException, IllegalAccessException {
        /*
        Android 5.x seems to use the internal activityChooserModel 
         */
        if (activityChooserGetMethod == null) {
            activityChooserModel = Class.forName("android.widget.ActivityChooserModel");
            activityChooserGetMethod = activityChooserModel.getMethod("get", new Class[]{Context.class, String.class});
        }

        Object activityChooserObject = activityChooserGetMethod.invoke(null, new Object[]{context, ShareActionProvider.DEFAULT_SHARE_HISTORY_FILE_NAME});
        for (Method method : activityChooserModel.getMethods()) {
            if (method.getName().equals("setOnChooseActivityListener")) {
                method.invoke(activityChooserObject, new Object[]{null});
                break;
            }
        }
    }
}

Also, Android Studio 2.1 doesn't resolve the import for
import android.support.v7.internal.widget.ActivityChooserModel;

From testing with LeakCanary, I've found that the fixInternalClass used onStop of any activity that uses the SharedActionProvider is sufficient for the latest versions of the support library.

public class SharedActionProviderContextLeak {

    public static void patch(Context context) {
        try {
            fixShareActionProvider(context);
        } catch (ClassNotFoundException ignored) {
        } catch (NoSuchMethodException ignored) {
        } catch (InvocationTargetException ignored) {
        } catch (IllegalAccessException ignored) { }
    }

        /*

        Class activityChooserModel = Class.forName("android.widget.ActivityChooserModel");
        Method activityChooserGetMethod = activityChooserModel.getMethod("get", new Class[]{Context.class, String.class});

        Object activityChooserObject = activityChooserGetMethod.invoke(null,
                new Object[] { context, ShareActionProvider.DEFAULT_SHARE_HISTORY_FILE_NAME });

        for (Method method : activityChooserModel.getMethods()) {
            if (method.getName().equals("setOnChooseActivityListener")) {
                method.invoke(activityChooserObject, new Object[]{null});
                break;
            }
        }
    }
