Android : android permission for camera and internet

In android, I remember that it was mandatory to request permission to use the Camera or to use the internet connection in a app.

But I did a small test in which I did not request any of the above permissions and I expected my test app to crash & burn.

But this did not happen!!

I was able to use the cammera and the internet without requesting for permissions, and I've tested on 3 devices all with different version of android.

Here is the code:

public class MainActivity extends Activity implements View.OnClickListener
{
    private int cameraCode = 0;
    private Button start_cam;
    private Button start_internet;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        start_cam = (Button) findViewById(R.id.camera);
        start_internet = (Button) findViewById(R.id.internet);

        start_cam.setOnClickListener(this);
        start_internet.setOnClickListener(this);
    }

    @Override
    public void onClick(View v)
    {
        switch(v.getId())
        {
            case R.id.camera:
                Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, cameraCode);
                break;
            case R.id.internet:
                Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.imdb.com"));
                startActivity(browserIntent);
                break;
        }
    }
}

the manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.permissions.linux.android">

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="16" />

    <application
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name">

        <activity
            android:name="com.permissions.linux.androi.android.MainActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>


    </application>

</manifest>

The question is why didn't it crashed??
