Update the *AndroidManifest.xml* File {#pax-aio-configure-android-manifest-xml}
===============================================================================

To support a large heap size and ensure the necessary permissions for the Default UI, update your `AndroidManifest.xml` file. Enabling a larger heap is essential for scenarios where terminal updates require the handling and transfer of large volumes of data.  
Follow these steps to update your *AndroidManifest.xml* file.

1. Set the `android:allowBackup` attribute to `false` and the `android:largeHeap` attribute to `true`.

   ```
   <application
       ...
       android:allowBackup="false"
       android:largeHeap="true"
       >
       ...
   </application>
   ```
2. Enable the needed permissions for the Default UI and PAX.

   ```
   <manifest ... >
       ...
       <!-- Needed for Default UI ! -->
       <uses-permission android:name="android.permission.INTERNET"/>
       <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
       <uses-permission android:name="android.permission.READ_PHONE_STATE"/>                   
       
       <!-- Needed for PAX integrations ! -->
       <uses-permission android:name="com.pax.permission.ICC"/>
       <uses-permission android:name="com.pax.permission.PICC"/>
       <uses-permission android:name="com.pax.permission.MAGCARD"/>
       <uses-permission android:name="com.pax.permission.PED"/>                
       ...
   </manifest>
   ```
