Trouble shoot for does not have android.permission.SEND_SMS case in Android

 Today I met error on android send SMS function with below error message

"does not have android.permission.SEND_SMS"

This problem came up on android API 23. 

I never met this kind of error under API 23.

What I found solution is that

first, give SEMD_SMS permission on AndroidManifest.xml file

<uses-permission android:name="android.permission.SEND_SMS" />

then, I implemented code like this

// first, call address intent to get person mobile number
public void sendBySMS() {
    Intent intent = new Intent(Intent.ACTION_PICK);
    intent.setData(ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
    startActivityForResult(intent, REQ_CODE_SMS_ADDRESS);
}

// second, after get person mobile number, call send sms function
@Override
protected void onActivityResult(int requestCode, int responseCode, Intent data) {
    switch (requestCode) {
        case REQ_CODE_SMS_ADDRESS:
            if (responseCode == RESULT_OK) {
                Cursor cursor = getContentResolver().query(data.getData(),
                        new String[]{ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
                                ContactsContract.CommonDataKinds.Phone.NUMBER}, null, null, null);
                cursor.moveToFirst();
                mName = cursor.getString(0);
                mMobileNumber = cursor.getString(1);
                cursor.close();

                // call send sms function which is created by me.
                smsMessageSent();
            }
            break;
    }
}

// call intent to send sms
public void smsMessageSent() {
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse( "sms:" + mMobileNumber ) );
    intent.putExtra( "sms_body", mContentToSend );
    startActivity(intent);
}

Here is what i used before (I mean under API 23 version)

It's just reference

public void smsMessageSent() {
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SENT), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0);

    //---when the SMS has been sent---
    registerReceiver(new BroadcastReceiver() {
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS sent", Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    }, new IntentFilter(SENT));

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(mMobileNumber, null, mContentToSend, sentPI, deliveredPI);
}
