I need to share an image (.png format) with transparent background, through sent_action intent.
I searched a lot and tried a lot of samples but couldn't find the solution.
The is this method in witch the image will get shared directly from the resources, but for some reason from some point it has stop working.
Uri url = Uri.parse("android.resource://"
+ getPackageName() + "/" + R.drawable.ic_launcher);
Intent share_intent = new Intent();
share_intent.setAction(Intent.ACTION_SEND);
share_intent.setType("image/png");
share_intent.putExtra(Intent.EXTRA_STREAM,
Uri.fromFile(new File(url.toString())));
startActivity(Intent.createChooser(share_intent, "choose app"));
and there is this function which works fine, the problem is it adds a black background to the image.
private void share3()
{
Bitmap bitmap;
OutputStream output;
bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
File filepath = Environment.getExternalStorageDirectory();
File dir = new File(filepath.getAbsolutePath() + "/Gallery/");
dir.mkdirs();
File file = new File(dir, "ic_launcher" + ".png");
try {
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/png");
output = new FileOutputStream(file);
bitmap. compress(Bitmap.CompressFormat.PNG/*Bitmap.CompressFormat.PNG*/, 0, output);
output.flush();
output.close();
Uri uri = Uri.fromFile(file);
share.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(share, "choose app"));
} catch (Exception e) {
e.printStackTrace();
}
}
I need to share the image from "raw" folder in the resources and share it without background. What should I do?
I found the problem, It is telegram itself. Telegram adds a black background to .png images you share.
Try this ..its work for me to share image from drawable folder.
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/LatestShare.png";
OutputStream out = null;
File file = new File(path);
try {
out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
path = file.getPath();
Uri bmpUri = Uri.parse("file://" + path);
Intent shareIntent = new Intent();
shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
shareIntent.setType("image/png");
startActivity(Intent.createChooser(shareIntent, "Share with"));

I am getting picture from a layout and do not want to save it. I want to share it directly through intent ACTION_SEND service. when I send it gives exception Transaction Too many Large: data parcel size 2315980 bytes
Here is my code snippet
View myview = (View) findViewById(R.id.mylayout);
Bitmap mypicture = getBitmapFromView(myview);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra("", mypicture);
intent.setType("image/jpeg");
startActivity(intent);
I want to share it directly through intent ACTION_SEND service
That is not an option. EXTRA_TEXT holds text. EXTRA_STREAM holds a Uri. Neither of those is a Bitmap.
Here is my code snippet
Your extra is pointless, as no ACTION_SEND activities will be looking for an extra with an empty key.
you can save your bitmap to a file, then share the uri/link to that file.
public static File saveBitmapInternal(Context context, Bitmap bitmap) {
File imagePath = new File(context.getFilesDir(), "images");
if (!imagePath.exists() && !imagePath.mkdirs()) {
print("Make dir failed");
}
return saveBitmap(bitmap, "preview.png", imagePath);
}
private static File saveBitmap(Bitmap bitmap, String filename, File root) {
print(String.format("Saving %dx%d bitmap to %s.", bitmap.getWidth(), bitmap.getHeight(), filename));
final File file = new File(root, filename);
if (file.exists()) {
file.delete();
}
try {
final FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 99, out);
out.flush();
out.close();
return file;
} catch (final Exception e) {
print("Exception!" + e);
}
return null;
}
then to share it,
// Uri uri = Uri.fromFile(file);
Uri uri = FileProvider.getUriForFile(context,
context.getString(R.string.file_provider_authority),
file);
final Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.putExtra(Intent.EXTRA_TEXT, shareText);
context.startActivity(Intent.createChooser(intent, "Share media"));
you need to set up the file provider in your manifest (refer to https://developer.android.com/reference/android/support/v4/content/FileProvider.html). you can create another question if you have queries regarding the fileprovider.
I am tring to share an image which i fetch from Json. After a number of attempts i finally concluded with this code. It works well till i open whatsapp and select the contact i want to share, the image doesnt load from there and when i click on submit, it says sharing failed.
Drawable drawable1 = imageViewPreview.getDrawable();
Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.id.image_preview);
File file = new File(SlideshowDialogFragment.this.getCacheDir(), String.valueOf(largeIcon + ".png"));
// FileOutputStream fOut = new FileOutputStream(file);
// largeIcon.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
file.setReadable(true, false);
final Intent intent = new Intent(Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
intent.setType("image/png");
startActivity(intent);
if i remove the comments
FileOutputStream fOut = new FileOutputStream(file);
will show error message and i have to add try/catch then, the app crashes saying Nullpoint exception
Try this code:
Bitmap bitmap = mBitmap;
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File f = new File(Environment.getExternalStorageDirectory() + File.separator + "photo.jpg");
try {
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
} catch (IOException e) {
e.printStackTrace();
}
share.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/photo.jpg"));
startActivity(Intent.createChooser(share, "Share Image"));
When I try to share an screenshot via the Samsung email app the preview of the image I am sending is wrong. It happens only with the Samsung email app.
Here is my code:
-------here I am taking a screenshot-----------
String mPath = "";
try {
// image naming and path to include sd card appending name you choose for file
mPath = Environment.getExternalStorageDirectory().toString() + "/" + "share" + ".jpeg";
// create bitmap screen capture
View v1 = getActivity().getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
File imageFile = new File(mPath);
FileOutputStream outputStream = new FileOutputStream(imageFile);
int quality = 100;
bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
outputStream.flush();
outputStream.close();
-------sending a screen shot via intent-----------
Uri imageUri = Uri.parse(sorcUrl);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(intent, "Share"));
} catch (Throwable e) {
// Several error may come out with file handling or OOM
e.printStackTrace();
}
I am writing an app to share image.
I wrote the code but getting problems.
What I am doing
1: Saving the image temporarily in Internal Stoarge
2: Passing the URI to share the image.
Image is successfully saved in internal storage but not getting share on whatsapp.
When I share it on whatsapp, Whatsapp get opens, I select recipient, whatsapp processes it and says "Retry".
Code:
public void shareImage(View V)
{
Bitmap icon = BitmapFactory.decodeResource(getResources(), R.drawable.download);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
icon.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File file = new File(Environment.getExternalStorageDirectory()
+ File.separator + "myDownloadedImage.jpg");
try
{
file.createNewFile();
FileOutputStream fo = new FileOutputStream(file);
fo.write(bytes.toByteArray());
fo.close();
} catch (IOException e) {
Toast.makeText(this, "Some error in Writing"+e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
Uri downloadLocation=Uri.fromFile(file);
share.putExtra(Intent.EXTRA_STREAM, downloadLocation);
startActivity(Intent.createChooser(share, "Share Image"));
}
Image succesfully get saved on internal storage but not getting shared on whatsapp.
The screenshot is below. We can see images are not shared successfully.
Use below code to fetch image and make uri:
File file = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOWNLOADS), "share_image_" + System.currentTimeMillis() + ".png");
file.getParentFile().mkdirs();
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
out.close();
bmpUri = Uri.fromFile(file);
Now pass the bmpUri in:
shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
This should make your image share.
I've used the following code to save an image file to the external storage
drawView.setDrawingCacheEnabled(true);
String img = MediaStore.Images.Media.insertImage(getContentResolver(),drawView.getDrawingCache(),UUID.randomUUID().toString()+".jpeg", "doodle");
I want to return this saved file to Whatsapp using an intent. Can somebody please help me out with the code? I'm new to android and would really appreciate it! Thanks :)
Try this code
Bitmap icon = mBitmap;
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
icon.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File f = new File(Environment.getExternalStorageDirectory() + File.separator + "temporary_file.jpg");
try {
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
} catch (IOException e) {
e.printStackTrace();
}
share.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/temporary_file.jpg"));
startActivity(Intent.createChooser(share, "Share Image"));
