안드로이드의 SDCARD를 저장하고 선택하여 이메일 본문에 이미지를 포함

StackOverflow https://stackoverflow.com/questions/19834933

문제

SDCard를 저장 한 다음 해당 장소에서 선택하여 이메일 본문에 인라인 이미지를 포함 시키려고하지만 이미지가 표시되지 않으며 "OBJ"만 표시됩니다.

   {

    Bitmap newImg=BitmapFactory.decodeByteArray(img,0,img.length);

    String root = Environment.getExternalStorageDirectory().toString();
    File myDir = new File(root + "/saved_images");    
    myDir.mkdirs();
    String fname = "stoneage.jpg";
    File file = new File (myDir, fname);

    try{
           FileOutputStream out = new FileOutputStream(file);
           newImg.compress(Bitmap.CompressFormat.JPEG, 90, out);
           out.flush();
           out.close();

    } catch (Exception e) {
           e.printStackTrace();
    }

    Uri uri = null;
    uri = Uri.parse("file://" + Environment.getExternalStorageDirectory()+"/saved_images/"+fname);


    String txtBody = "<html><body><h1>hi it is stoneage product</h1><br><img src ="+uri+"/></body></html>";
    Log.d("data", txtBody);

    Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.setType("text/html");

  emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "testemail");
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(txtBody));
    startActivity(Intent.createChooser(emailIntent, "Email:"));  }

해결책

파일을 저장하려면 이것을 시도하십시오.

    try {
        File myFile = new File("/sdcard/mysdfile.jpg");
        myFile.createNewFile();
        FileOutputStream fOut = new FileOutputStream(myFile);
        OutputStreamWriter myOutWriter = 
                                new OutputStreamWriter(fOut);
        myOutWriter.append(txtData.getText());
        myOutWriter.close();
        fOut.close();
        Toast.makeText(getBaseContext(),
                "Done writing SD 'mysdfile.txt'",
                Toast.LENGTH_SHORT).show();
    } catch (Exception e) {
        Toast.makeText(getBaseContext(), e.getMessage(),
                Toast.LENGTH_SHORT).show();
    }





    Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
    emailIntent.setType("application/image");
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{strEmail}); 
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Test Subject"); 
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "From My App"); 
    emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///mnt/sdcard/mysdfile.jpg"));
    startActivity(Intent.createChooser(emailIntent, "Send mail..."));
