Is it possible to keep the device restarting？

[FloatingGuy]

Is there a way to automatically pull up the StartFlagExploit APP after the system_server restarts, so that the phone will continue to be restarted?
I tried to register the system startup broadcast, but my receiver did not receive any system startup broadcast. I think it is because my APP has not started yet, so I can't receive the broadcast. And the system did not send the android.intent.action.BOOT_COMPLETED broadcast.

My test code:
test devices: pixel 4XL android10

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

<receiver
            android:name=".BootCompletedReceiver"
            android:enabled="true">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.BATTERY_CHANGED" />
                <action android:name="android.intent.action.LOCKED_BOOT_COMPLETED"/>

            </intent-filter>

            <intent-filter>
                <action android:name="android.intent.action.BATTERY_CHANGED" />
                <action android:name="android.intent.action.ACTION_POWER_DISCONNECTED" />
                <action android:name="android.intent.action.DOCK_EVENT" />
                <action android:name="android.intent.action.ACTION_SHUTDOWN" />
                <action android:name="com.android.intent.action.timezone.TRIGGER_RULES_UPDATE_CHECK" />
                <action android:name="com.android.frameworks.coretests.activity.BROADCAST_REGISTERED" />
                <action android:name="com.android.frameworks.coretests.activity.BROADCAST_LOCAL" />
                <action android:name="com.android.frameworks.coretests.activity.BROADCAST_REMOTE" />

            <intent-filter>

                <action android:name="android.intent.action.ACTION_SHUTDOWN" />
            </intent-filter>

            <intent-filter>
                <action android:name="android.intent.action.USER_PRESENT" />
            </intent-filter>

        </receiver>

public class BootCompletedReceiver extends BroadcastReceiver {
    private static final String TAG = "systemcrash";
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent in = null;
        switch (intent.getAction()) {

                in = new Intent();
                in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                in.setClassName("com.facat.systemcrash", "MainActivity");
                context.startActivity(in);
            case ...
            
            default:
                Log.e(TAG,"default: " + intent.getAction());
                in = new Intent();
                in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                in.setClassName("com.facat.systemcrash", "MainActivity");
