Как отправить URL-адрес изображения в WhatsApp на Android?
Автор вопроса: ramsОтветов: 5
Мне нужно поделиться изображением с WhatsApp в моем приложении. У меня есть URL-адрес изображения. Для отправки в WhatsApp я использую следующий код.
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();
}
Но это не сработало. Я получаю следующую ошибку.

Для этого я много искал в Google и перешел по указанному ниже URL-адресу.
whatsapp.setOnClickListener(new View.OnClickListener() {

Intent intent1 = c.getPackageManager().getLaunchIntentForPackage("com.whatsapp");
if(intent1!=null)

whatsappIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
whatsappIntent.setType("image/*");
whatsappIntent.setPackage("com.whatsapp");
String url = Spacecraft.new_image_array.get(position);
new Download_GIF(url).execute();
Uri imageUri = Uri.parse("file:///storage/emulated/0/downloadedFile.gif");
whatsappIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
c.startActivity(whatsappIntent);
}
Класс Download_GIF.

Сначала вам нужно загрузить изображение в glide, после чего вы сможете поделиться им где угодно.
Код для загрузки изображения из glide (изображение сохраняется в хранилище, вы можете удалить его позже)
Glide.with(getApplicationContext())
.load(imagelink) \\link of your image file (url)
.asBitmap().skipMemoryCache(true).diskCacheStrategy(DiskCacheStrategy.NONE)
.into(new SimpleTarget<Bitmap>(250, 250) {@Override
public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "Hey view/download this image");
String path = MediaStore.Images.Media.insertImage(getContentResolver(), resource, "", null);
Log.i("quoteswahttodo", "is onresoursereddy" + path);
Uri screenshotUri = Uri.parse(path);
Log.i("quoteswahttodo", "is onresoursereddy" + screenshotUri);
intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
intent.setType("image/*");
startActivity(Intent.createChooser(intent, "Share image via...")); // if you want to share with whatsapp only replace with below code
}
@Override public void onLoadFailed(Exception e, Drawable errorDrawable) {
Toast.makeText(getApplicationContext(), "Something went wrong", Toast.LENGTH_SHORT).show();
super.onLoadFailed(e, errorDrawable);
}
@Override public void onLoadStarted(Drawable placeholder) {
Toast.makeText(getApplicationContext(), "Starting", Toast.LENGTH_SHORT).show();
super.onLoadStarted(placeholder);
}
});
Здесь заменить на WhatsApp:
sendd.setPackage("com.whatsapp");
try {
startActivity(sendd);
} catch (Exception e) {
Toast.makeText(FinishedDoing.this, "It seem like Whatsapp is not been installed", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
