title: Send sms permission doesn't work
body: <p>I want to send a simple message and i have <code>&lt;uses-permission android:name="android.permission.SEND_SMS"/&gt;</code> in my manifest, but I always get: <code>java.lang.SecurityException: Sending SMS message: uid 10064 does not have android.permission.SEND_SMS.</code></p>
  
  <p>I checked <a href="https://stackoverflow.com/questions/23210056/sms-permissions-not-working-no-matter-where-i-put-the-permission-tag">this answer</a>, but it still doesn't work.</p>
  
  <p>this is my manifest:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.roa.sendsms" &gt;
  
  
  &lt;uses-permission android:name="android.permission.SEND_SMS"/&gt;
  
  &lt;application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:supportsRtl="true"
      android:theme="@style/AppTheme" &gt;
      &lt;activity
          android:name=".MainActivity"
          android:label="@string/app_name"
          android:theme="@style/AppTheme.NoActionBar" &gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
  
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  &lt;/application&gt;
  </code></pre>
  
  <p></p>
  
  <p>and this is my code:</p>
  
  <pre><code>package com.roa.sendsms;
  
  import android.os.Bundle;
  import android.support.design.widget.FloatingActionButton;
  import android.support.design.widget.Snackbar;
  import android.support.v7.app.AppCompatActivity;
  import android.support.v7.widget.Toolbar;
  import android.telephony.SmsManager;
  import android.view.View;
  import android.view.Menu;
  import android.view.MenuItem;
  import android.widget.Button;
  
  public class MainActivity extends AppCompatActivity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
      setSupportActionBar(toolbar);
  
      Button sendButton =  (Button)findViewById(R.id.sendButton);
      sendButton.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              sendSms(phoneNumber, "you get message from roish app!!");
          }
      });
  }
  
  private void sendSms(String phoneNumber, String message){
      SmsManager sms = SmsManager.getDefault();
      sms.sendTextMessage(phoneNumber, null, message, null, null);
  }
  </code></pre>
  
  <p>}</p>
