The value must be set as an integer, such as "100". You can define it however

<th>Description</th>
</tr><tr>
<td>"{@code auto}"</td>
<td>Let the system decide the ideal install location. This will usually be based on the user's
saved preference.</td>
</tr><tr>
<td>"{@code internalOnly}"</td>
<td>Request to be installed only on the internal device storage. If this is set, then
the application will never be installed on the external storage (SD card). If the internal storage
is full, then the application will not install.</td>
</tr><tr>
<td>"{@code preferExternal}"</td>
<td>Prefer to be installed on external storage (SD card). There is no guarantee that the system
will honor this request. The application might be installed on internal storage if the
external media is unavailable or full, or if the application uses the forward-locking mechanism
(not supported on external storage).</td>

<p>When an application is installed on the external storage:</p>
<ul>
<li>The {@code .apk} file is saved
to the external storage, but any application data (such as databases) is still saved on
the internal device memory.</li>
<li>The container in which the {@code .apk} file is saved is encrypted with a key that allows
the application to operate only on the device that installed it. (A user cannot
transfer the SD card to another device and use applications installed on the card.) Though,
multiple SD cards can be used with the same device.</li>
<li>At the user's request, the application can be moved to the internal storage.</li>
</ul>
<p>The user may also request to move an application from the internal storage to the external
storage. However, this will not be allowed if this attribute is set to {@code internalOnly}.
