I am trying to share an image to other apps.
From the doc, I understand I have to create a ContentProvider
to ensure access to my resource from outside the app. It works with most apps but Facebook Messenger and Messages (com.android.mms). I have the following errors:
FB Messenger: "Sorry, messenger was unable to process the file"
com.android.mms: "Unable to attach. File not supported"
The code I call in the activity to share:
Uri path = Uri.parse("content://com.myauthority/test.png");
Intent shareIntent = new Intent(Intent.ACTION_SEND).putExtra(Intent.EXTRA_STREAM, path).setType("image/png");
startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.share)));
The in my content provider I only override openFile:
@Override
public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException {
String fileName = uri.getLastPathSegment();
String resName = fileName.replaceAll(".png","");
int resId = getContext().getResources().getIdentifier(resName,"drawable",getContext().getPackageName());
File file = new File(getContext().getCacheDir(), fileName);
Bitmap bitmap = BitmapFactory.decodeResource(getContext().getResources(), resId);
FileOutputStream fileoutputstream = new FileOutputStream(file);
boolean flag = bitmap.compress(Bitmap.CompressFormat.PNG, 100, fileoutputstream);
try {
ParcelFileDescriptor parcelfiledescriptor = ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY | ParcelFileDescriptor.MODE_WORLD_READABLE);
return parcelfiledescriptor;
} catch (IOException e) {
e.printStackTrace();
return null;
}
Has anyone an idea or experience to share regarding this issue?
