如何在 Android 中将图像 URL 分享到 WhatsApp？

我需要在我的应用程序中将图像分享到 WhatsApp。我有图片网址。为了分享到 WhatsApp，我使用以下代码。

String image_url = "http://images.cartradeexchange.com//img//800//vehicle//Honda_Brio_562672_5995_6_1438153637072.jpg";

URI uri = null;
try {
    uri = new URI(image_url.toString());
} catch (URISyntaxException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
Log.e("uri=", "" + uri);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.setType("image/jpg");

// Target whatsapp:
shareIntent.setPackage("com.whatsapp");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

try {
    startActivity(shareIntent);
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(InventoryManageOnlineActivity.this,
            "Whatsapp have not been installed.",
            Toast.LENGTH_SHORT).show();
}

但这没有用。我收到以下错误。

为此，我在谷歌上搜索了很多，然后我点击了下面的网址

Android 共享图片不起作用.

但这对我来说没有用。请告诉我如何共享图像 URL。

如何在android中的ImageView上设置的whatsapp上共享图像.

顺便说一句，我不明白你为什么这么做image_url.toString()？它已经在字符串中了，对吗？

也尝试一下这个代码。

String image_url = "http://images.cartradeexchange.com//img//800//vehicle//Honda_Brio_562672_5995_6_1438153637072.jpg";

        Intent shareIntent = new Intent();
        shareIntent.setType("image/*");
        shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        shareIntent.setAction(Intent.ACTION_SEND);
        //without the below line intent will show error
        shareIntent.setType("text/plain");
        shareIntent.putExtra(Intent.EXTRA_TEXT, image_url);
                // Target whatsapp:
        shareIntent.setPackage("com.whatsapp");
        shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

                try {
                    startActivity(shareIntent);
                } catch (android.content.ActivityNotFoundException ex) {
                    Toast.makeText(InventoryManageOnlineActivity.this,
                            "Whatsapp have not been installed.",
                            Toast.LENGTH_SHORT).show();
                }
