I have gone through many articles. But somehow i could not achieve what i wanted to achieve. I have a http image link in my app and i want to share this as an image attachment from Twitter application. I have tried following. But it seems not to be working as Twitter expects it to be a local url.
TweetComposer.Builder builder = new TweetComposer.Builder(context)
.text(text)
.image(Uri.parse("https://dummyimage.com/300/09f/fff.png"));
builder.show();
So now that i know it requires a local path, i tried to download the image to phone using Picasso as below.
Picasso.get().load(CONSTANT.IAMGE_URI + list.get(position).getEvent_model().getPhoto_link())
.placeholder(R.drawable.placeholder)
.error(R.drawable.placeholder)
.into(getTarget(list.get(position).getEvent_model().getPhoto_link()));
File myImageFile = new File(getFileFullPath(list.get(position).getEvent_model().getPhoto_link()));
Picasso.get().load(myImageFile).into(holder.iv_album_image);
And this is code to get the target.
private static Target getTarget(final String fileName) {
Target target = new Target() {
//This method in target is called by picasso when image downloaded
@Override
public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
new Thread(new Runnable() {
@Override
public void run() {
try {
File file = new File(getFilename(fileName));
if (file.exists()) {
file.delete();
}
file.createNewFile();
FileOutputStream fileoutputstream = new FileOutputStream(file);
ByteArrayOutputStream bytearrayoutputstream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 60, bytearrayoutputstream);
fileoutputstream.write(bytearrayoutputstream.toByteArray());
fileoutputstream.close();
} catch (IOException e) {
Log.e("IOException", e.getLocalizedMessage());
}
}
}).start();
}
@Override
public void onBitmapFailed(Exception e, Drawable errorDrawable) {
}
@Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
}
};
return target;
}
public static String getFilename(String fileName) {
File file = new File(Environment.getExternalStorageDirectory().getPath(), "Images");
if (!file.exists()) {
file.mkdirs();
}
return (file.getAbsolutePath() + "/" + fileName);
}
In this case photo is not loading in to imageview and also not being downloaded to local.
You need to download the image to your phone, and use a local path.
Ultimately for image: The Uri should be a file Uri to a local file
Uri.fromFile(someExternalStorageFile)
Can you change your getFilename to match as such:
public static String getFilename(String fileName, Context context) {
int code = context.getPackageManager().checkPermission(
android.Manifest.permission.WRITE_EXTERNAL_STORAGE,
context.getPackageName());
if (code == PackageManager.PERMISSION_GRANTED) {
File file = new File(Environment.getExternalStorageDirectory().getPath(), "Images");
if (!file.exists()) {
file.mkdirs();
}
return (file.getAbsolutePath() + "/" + fileName);
}
return "";
}
And set a breakpoint at each return. My assumption is you're returning "";
