Ich kann keine E-Mail senden, tritt es immer um den Block fangen ... .. Ich habe javax.mail.jar, activation.jar, joda-time.jar
Bitte helfen Sie mir, dieses Problem zu lösen ... Ich brauche Danke E-Mail über meine App senden programmatisch im Voraus

Answer 1

Lokale Adresse enthält Steuer oder Leerzeichen in String `` Sender E-Mail ‚‘

Schauen Sie sich diese Linie . Ihre E-Mail enthält Leerzeichen. Versuchen Sie, die Validierung für E-Mails zu aktivieren. Dies ist in der Validierung eingebaut. Sie können auch nach anderen Möglichkeiten suchen.

public final static boolean isValidEmail(CharSequence target) { 
    if (target == null) { 
     return false; 
    } else { 
     return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches(); 
    } 
} 

und für Ihren Code versuchen, dies zu tun:

m.setFrom("senderEmail"); 

Dies ist, wie Sie E-Mail in android senden:

Intent i = new Intent(Intent.ACTION_SEND); 
i.setType("message/rfc822"); 
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"recipient@example.com"}); 
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email"); 
i.putExtra(Intent.EXTRA_TEXT , "body of email"); 
try { 
    startActivity(Intent.createChooser(i, "Send mail...")); 
} catch (android.content.ActivityNotFoundException ex) { 
    Toast.makeText(MyActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show(); 
}
