我在（android 2.3）中共享图像时遇到了麻烦，我尝试在 Jelly Bean 中共享并且它有效。我已经在 30 多台运行 Android 2.3 的设备上测试了我的应用程序，并且所有设备的共享选项都不起作用。当我单击共享按钮时，它会显示一条消息：“无法加载资源”..：/

这是我的代码：

public class ImagePager extends BaseActivity implements OnClickListener {

    Button share, back;
    private static final String STATE_POSITION = "STATE_POSITION";
    public String image;
    ViewPager pager;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ac_image_pager);

        share = (Button)findViewById(R.id.share);
        back = (Button)findViewById(R.id.back);

        share.setOnClickListener(this);
        back.setOnClickListener(this);

        Bundle bundle = getIntent().getExtras();
        String[] imageUrls = bundle.getStringArray(Extra.IMAGES);
        int pagerPosition = bundle.getInt(Extra.IMAGE_POSITION, 0);

        if (savedInstanceState != null) {
            pagerPosition = savedInstanceState.getInt(STATE_POSITION);
        }

        pager = (ViewPager) findViewById(R.id.pager);
        pager.setAdapter(new ImagePagerAdapter(imageUrls));
        pager.setCurrentItem(pagerPosition);    
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        outState.putInt(STATE_POSITION, pager.getCurrentItem());
    }

    private class ImagePagerAdapter extends PagerAdapter {

        private String[] images;
        private LayoutInflater inflater;

        ImagePagerAdapter(String[] images) {
            this.images = images;
            inflater = getLayoutInflater();
        }

        @Override
        public void destroyItem(ViewGroup container, int position, Object object) {
            ((ViewPager) container).removeView((View) object);
        }

        @Override
        public void finishUpdate(View container) {
        }

        @Override
        public int getCount() {
            return images.length;
        }

        @Override
        public Object instantiateItem(ViewGroup view, int position) {


            View imageLayout = inflater.inflate(R.layout.item_pager_image, view, false);
            ImageView imageView = (ImageView) imageLayout.findViewById(R.id.image);
            final ProgressBar spinner = (ProgressBar) imageLayout.findViewById(R.id.loading);

            imageLoader.displayImage(images[position], imageView, options, new SimpleImageLoadingListener() {
                @Override
                public void onLoadingStarted(String imageUri, View view) {
                    spinner.setVisibility(View.VISIBLE);
                }

                @Override
                public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
                    String message = null;
                    switch (failReason.getType()) {
                        case IO_ERROR:
                            message = "Input/Output error";
                            break;
                        case DECODING_ERROR:
                            message = "Image can't be decoded";
                            break;
                        case NETWORK_DENIED:
                            message = "Downloads are denied";
                            break;
                        case OUT_OF_MEMORY:
                            message = "Out Of Memory error";
                            break;
                        case UNKNOWN:
                            message = "Unknown error";
                            break;
                    }
                    Toast.makeText(ImagePager.this, message, Toast.LENGTH_SHORT).show();

                    spinner.setVisibility(View.GONE);
                }

                @Override
                public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
                    spinner.setVisibility(View.GONE);
                }
            });

            ((ViewPager) view).addView(imageLayout, 0);
            return imageLayout;
        }

        @Override
        public boolean isViewFromObject(View view, Object object) {
            return view.equals(object);
        }

        @Override
        public void restoreState(Parcelable state, ClassLoader loader) {
        }

        @Override
        public Parcelable saveState() {
            return null;
        }

        @Override
        public void startUpdate(View container) {
        }
    }

@Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.share:
            int position = pager.getCurrentItem();
            switch (position) {
            case 0:
                image="c1";
                break;
            case 1:
                image="c2";
                break;
            case 2:
                image="c3";
                break;
            case 3:
                image="c4";
                break;
            case 4:
                image="c5";
                       }
        //Here is my share code.... I don't know really what the problem is.
            //And why this not works in Android 2.3


        Uri imageUri = Uri.parse("android.resource://mypackagename/drawable/"+image);

        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("image/jpg");

        intent.putExtra(Intent.EXTRA_STREAM, imageUri);
        startActivity(Intent.createChooser(intent , "Share"));

            break;

        case R.id.back:
            this.finish();
            break;
        }
    }
}

我有另一个用于设置图像资源的类，代码如下：

public final class Constants {

    public static final String[] IMAGES = new String[] {
        "drawable://" + R.drawable.c1,
        "drawable://" + R.drawable.c2,
        "drawable://" + R.drawable.c3,
        "drawable://" + R.drawable.c4,
        "drawable://" + R.drawable.c5
};

    private Constants() {
    }

    public static class Config {
        public static final boolean DEVELOPER_MODE = false;
    }

    public static class Extra {
        public static final String IMAGES = "mypackagename.IMAGES";
        public static final String IMAGE_POSITION = "mypackagename.IMAGE_POSITION";
    }
}

尝试使用 Images.Media.insertImage(..) 共享位图时遇到了同样的问题。解决方案是在清单中添加权限：“android.permission.WRITE_EXTERNAL_STORAGE”。发现在某些设备上它可以在没有此权限的情况下工作，但有时不会，这取决于供应商。

应该有帮助。祝你好运。
