Question: Yesterday I got a new upgrade for the Android N preview. Ever since I upgraded, I cannot start my app anymore. 

```
java.io.IOException: Cleartext HTTP traffic to myserver.com not permitted

```

I have tried to set the `usesCleartextTraffic` to `true` in the manifest or to add a `network_security_config.xml` 

```
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">myserver.com</domain>
    </domain-config>
</network-security-config>

```

Neither did work. Any ideas about what is going on there?

When I try to define networkSecurityConfig in the manifest, I get a compile error

```
Error:(35) No resource identifier found for attribute 'networkSecurityConfig' in package 'android'

```

Not really sure why. The file is there and everything looks good.

Found [this](https://code.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Status%20Priority%20Owner%20Summary%20Stars%20Reporter%20Opened&groupby=&sort=&id=212584) suggestion in the Android issue tracker from Google. They suggest to move the `network_security_config` definition to the `meta-data`. I still get the same exception though.

Answer: 
```
android:usesCleartextTraffic="true"

```

put this line in application tag in manifest file
```
<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
       ...
       android:usesCleartextTraffic="true"
       ...>
    </application>
</manifest>

```

This one worked perfectly for me :)
