无法通过ShareActionProvider共享图像

Question

我首先尝试从Gallery中获取一个简单的图像，相应地更新我的图像视图，然后应用两种方法进行共享，一种是通过简单的共享按钮，另一种是使用ShareActionProvider。 Whatsapp（或任何其他应用程序）在使用Action Bar共享时崩溃，但与简单的共享按钮完美共享。

ShareActionProvider完美地共享文本但不共享图像。请帮忙

以下是我的菜单文件

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"

<item
    android:title="@string/action_share"
    android:id="@+id/action_share"
    android:orderInCategory="2"
    app:showAsAction="always"
    app:actionProviderClass="android.support.v7.widget.ShareActionProvider"


    />

以下是我的ShareActivity.java

// Share image

//Sharing through ShareActionButton

    //Share Action Provider
    MenuItem menuItem = menu.findItem(R.id.action_share);

以下是我用来获取位图图像的util函数

package com.example.android.shareactivity;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;

import java.io.FileNotFoundException;

/**

public class utils {
    public static Bitmap decodeUri(Context context, Uri uri,
                                   final int requiredSize) throws FileNotFoundException {
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(context.getContentResolver()
                .openInputStream(uri), null, o);

        int width_tmp = o.outWidth, height_tmp = o.outHeight;
        int scale = 1;

        while (true) {
            if (width_tmp / 2 < requiredSize || height_tmp / 2 < requiredSize)
                break;
            width_tmp /= 2;
            height_tmp /= 2;
            scale *= 2;
        }

        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeStream(context.getContentResolver()
                .openInputStream(uri), null, o2);
    }
}
