I have bitmap in my code and i need to send it by email as attachment.
I saved it as file and make send intent but every time i have error (file not found).
this is my code.

save file :

private void savePicture(String filename, Bitmap b, Context ctx) {
    try {
        FileOutputStream out;
        out = ctx.openFileOutput(filename, Context.MODE_APPEND);

        b.compress(Bitmap.CompressFormat.JPEG, 40, out);
        if (b.compress(Bitmap.CompressFormat.JPEG, 40, out) == true) {
            Toast.makeText(act,"file created",Toast.LENGTH_LONG).show();
            out.close();
        }
    } catch (Exception e) {
        e.printStackTrace();
        Toast.makeText(act,e.getMessage(),Toast.LENGTH_LONG).show();
    }
}

public void sendmail (String filename){
        String path = Environment.getExternalStorageDirectory().toString();
        File file = new File(path,filename+".JPEG");
        Uri pngUri = Uri.fromFile(file);

        emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, pngUri);
        startActivity(Intent.createChooser(emailIntent,"send quotation"));
}

First of all doing

b.compress(Bitmap.CompressFormat.JPEG, 40, out);
    if (b.compress(Bitmap.CompressFormat.JPEG, 40, out) == true) {

you are calling twice b.compress(Bitmap.CompressFormat.JPEG, 40, out);

You should do something like boolean success = b.compress(Bitmap.CompressFormat.JPEG, 40, out); if(success){ // Your code } boolean success = b.compress(Bitmap.CompressFormat.JPEG, 40, out); if(success){ // Your code }

Said that, are you targetting Android N or higher version? If yes, you probably need to grant uri permissions

See File providers and grant permissions from official documentation
