question

Hello,

Welcome to our Microsoft Q&A platform!

Have you added the following permission in file AndroidManifest.xml ?

 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

I tried to create a new demo to achieve this function , and it works properly in my device (Google Pixel 8.1).
The main code is:

1.create a BootReceiver

 [BroadcastReceiver(Enabled = true, DirectBootAware = true, Exported = true)]
 [IntentFilter(new[] { Intent.ActionBootCompleted }, Priority = (int)IntentFilterPriority.HighPriority)]
 public class BootReceiver : BroadcastReceiver
 {
     public override void OnReceive(Context context, Intent intent)
     {
         Intent i = new Intent(context, typeof(MainActivity));
         i.AddFlags(ActivityFlags.NewTask);
         context.StartActivity(i);
     }
 }

2.added the following permission in file AndroidManifest.xml

  <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Note: we should change receiver android:name= into above receiver we created (`BootReceiver `)

Best Regards,

Jessie Zhang

Hi Jessie,

Yes, I forgot to say that I added also this permission in my manifest as suggested by my others readings...

I just ask a simple question: how can you add <receiver> tag in you manifest in you Xamarin Forms app ? If I do so (that was I made the first time), I got an error during compilation (or deployment, I do not remember exactly).

Documentation says that the manifest is automatically updated according to attributes set on the function...and when I go to the "obj" subfolder of my android project, I can find the modified manifest that contains thes lines :

 <application android:largeHeap="true" android:label="ElhomMobilityStorengy" 
                        android:name="crc64d3e6e025a3206700.MainApplication" android:allowBackup="true" android:icon="@drawable/icon" 
                        android:debuggable="true" android:extractNativeLibs="true">
      ....
      <receiver android:enabled="true" android:exported="true" android:name="crc64d3e6e025a3206700.ServiceStarter">
       <intent-filter>
         <action android:name="android.intent.action.BOOT_COMPLETED" />
       </intent-filter>
     </receiver>
     ....
   </application>

I see some difference with your code, for exemple the presence of permission attribute on the rceiver tag...could it be the problem in my case ? I see that I can put a Permission on the BroadCastReciver attribute...

Regards.
