我正试图在屏幕上显示传入的短信。但是当我发送新的短信时，什么也没发生。
我正在使用Nexus 5（Api 23）模拟器。
调试时我得到了：
权限拒绝：接收Intent {act = android.provider.Telephony.SMS_RECEIVED flg = 0x8000010（有额外内容）}需要android.permission.RECEIVE_SMS，因为发件人com.android.phone
在MainActivity.Java中我处理权限。
@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);
}
}
我做错了什么？ 你能救我吗？

我在AndroidManifest.xml上缺少MAIN内部活动标记。
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
