<h3 id="Permission">Requesting User Permissions</h3>



<p>In order to receive location updates from <code>NETWORK_PROVIDER</code> or

<code>GPS_PROVIDER</code>, you must request user permission by declaring either the {@code

ACCESS_COARSE_LOCATION} or {@code ACCESS_FINE_LOCATION} permission, respectively, in your Android

manifest file. For example:</p>

<p>

  In order to receive location updates from {@link

  android.location.LocationManager#NETWORK_PROVIDER} or {@link

  android.location.LocationManager#GPS_PROVIDER}, you must request the user's

  permission by declaring either the {@code ACCESS_COARSE_LOCATION} or {@code

  ACCESS_FINE_LOCATION} permission, respectively, in your Android manifest file.

  Without these permissions, your application will fail at runtime when

  requesting location updates.

</p>



<p>

  If you are using both {@link

  android.location.LocationManager#NETWORK_PROVIDER} and {@link

  android.location.LocationManager#GPS_PROVIDER}, then you need to request only

  the {@code ACCESS_FINE_LOCATION} permission, because it includes permission

  for both providers. (Permission for {@code ACCESS_COARSE_LOCATION} includes

  permission only for {@link

  android.location.LocationManager#NETWORK_PROVIDER}.)

</p>



<p class="note">

  <strong>Note:</strong> If your app targets Android 5.0 (API level 21) or

  higher, you must also declare that your app uses the

  <code>android.hardware.location.network</code> or

  <code>android.hardware.location.gps</code> hardware feature in the manifest

  file, depending on whether your app receives location updates from {@link

  android.location.LocationManager#NETWORK_PROVIDER} or from {@link

  android.location.LocationManager#GPS_PROVIDER}. If your app receives location

  information from both of these providers, you need to declare that the app

  uses both <code>android.hardware.location.network</code> and

  <code>android.hardware.location.gps</code>.

</p>



<p>

   The following code sample demonstrates how to declare the permission and

   hardware feature in the manifest file of an app that reads data from the

   device's GPS:

</p>

<pre>

&lt;manifest ... &gt;

    &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;

    ...

    &lt;!-- Needed only if your app targets Android 5.0 (API level 21) or higher. --&gt;

    &lt;uses-feature android:name="android.hardware.location.gps" /&gt;

    ...

&lt;/manifest&gt;

</pre>



<p>Without these permissions, your application will fail at runtime when requesting

location updates.</p>



<p class="note"><strong>Note:</strong> If you are using both <code>NETWORK_PROVIDER</code> and

<code>GPS_PROVIDER</code>, then you need to request only the {@code ACCESS_FINE_LOCATION}

permission, because it includes permission for both providers. (Permission for {@code
