Android - API 23 - Not able to display incoming sms

Question

I'm trying to show on the screen the incoming sms. But nothing is happening when I send a new sms.

I'm using Nexus 5 (Api 23) emulator.

When debugging I got:

Permission Denial: receiving Intent {act=android.provider.Telephony.SMS_RECEIVED flg=0x8000010 (has extras) } requires android.permission.RECEIVE_SMS due to sender com.android.phone

In MainActivity.Java I deal with the permissions.

@TargetApi(Build.VERSION_CODES.M)
public void getPermissionToReceiveSMS() {

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECEIVE_SMS)
            != PackageManager.PERMISSION_GRANTED) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if (shouldShowRequestPermissionRationale(Manifest.permission.RECEIVE_SMS)) {
                // Show our own UI to explain to the user why we need to read the contacts
                // before actually requesting the permission and showing the default UI
            }
        }

        requestPermissions(new String[]{Manifest.permission.RECEIVE_SMS},REQUEST_RECEIVE_SMS);
    }
}

What Am I doing wrong? Could you help me out?

Answer 1

I was missing the MAIN inside activity tag on AndroidManifest.xml.

<activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
