Versenden mehrerer Anhänge in einer E-Mail: Android.intent.extra.STREAM erwartet Parcelable

Question

Mögliches Duplikat:
wie man mehrere Dateien an einen E-Mail-Client in Android anhängt.

Hallo,

Ich kann eine E-Mail mit mehreren Anhängen nicht versenden.

Hier ist der Code, den ich im Internet und in Tutorials gefunden habe:

String[] mArray = getResources().getStringArray(R.array.pdf_entries);               
int i = 0;
Intent theIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
theIntent.setType("application/pdf");

ArrayList<Uri> uris = new ArrayList<Uri>();

for (String file : mArray) {
    if (booleans[i]) {
        File fileIn = new File("/sdcard/mydir/"+file+".pdf");
        Uri u = Uri.fromFile(fileIn);
        Log.i("","** add: "+u);
        uris.add(u);
    }
    i++;
}
theIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(Intent.createChooser(theIntent,"Select email application."));

Aber ich bekomme immer diesen Fehler:

Vielen Dank für jede Anregung/jeden Leitfaden.

Answer 1

Anhängen mehrerer Dateien an einen E-Mail-Client in Android

EDIT(zu dem Punkt, wo der Unterschied liegt):

Intent.ACTION_SEND != Intent.ACTION_SEND_MULTIPLE

Answer 2

    public class EmailActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);       
    }

    public void buttonClickMethod(View buttonObject){
            emailMultipleFiles(arrayOfFilestoSend[],"Subject","Message Content");
    }

    private void emailMultipleFiles(File[] attachmentFiles, String subjectContent, String messageContent) {
            Intent email = new Intent(Intent.ACTION_SEND_MULTIPLE);
            email.putExtra(Intent.EXTRA_SUBJECT, subjectContent);
            email.putExtra(Intent.EXTRA_TEXT, messageContent);

            ArrayList<Uri> uriList = new ArrayList<Uri>();
            for (int i = 0; i < attachmentFiles.length; i++) {
                uriList.add(Uri.fromFile(attachmentFiles[i]));
            }

            email.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uriList);
            email.setType("text/plain");
            /** or use **/ 
            email.setType("message/rfc822");
            startActivity(email);
    }
    }
