android - 导出的应用程序（android）没有全部功能

Question

当我通过 USB 直接从 android studio 将应用程序安装到我的手机上时，一切正常。我正在处理使用这种方法的推送通知。但是，当我在 android studio 中导出我的应用程序并获取 apk 文件，然后根据这个 apk 文件将其安装到我的手机上时，一切正常，但没有通知？

你明白我的意思吗？我可以直接在我的手机上播放我的每个 android studio 应用程序，并且它 100% 运行良好（我也收到了预期的推送通知）。

导出后，我得到一个 apk 文件。我手动安装了这个apk文件，我得到了我的应用程序，它起初看起来很棒，只有通知没有出现，尽管当我直接通过android studio安装它时它们会出现。

我究竟做错了什么？apk文件不是正确的文件吗？也许我需要另一个文件？代码必须是好的，因为在 android studio 中推送播放时一切都很好。

编辑：这是我的通知代码：

import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.ContextWrapper;
import android.content.Intent;
import android.graphics.Color;
import android.os.Build;

import androidx.annotation.RequiresApi;
import androidx.core.app.NotificationCompat;
import androidx.core.app.NotificationManagerCompat;

import java.util.Random;

public class NotificationHelper extends ContextWrapper {

    private static final String TAG = "NotificationHelper";

    public NotificationHelper(Context base) {
        super(base);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            createChannels();
        }
    }

    private String CHANNEL_NAME = "High priority channel";
    private String CHANNEL_ID = "com.example.notifications" + CHANNEL_NAME;

    @RequiresApi(api = Build.VERSION_CODES.O)
    private void createChannels() {
        NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
        notificationChannel.enableLights(true);
        notificationChannel.enableVibration(true);
        notificationChannel.setDescription("this is the description of the channel.");
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        manager.createNotificationChannel(notificationChannel);
    }

    public void sendHighPriorityNotification(String title, String body, Class activityName) {

        Intent intent = new Intent(this, activityName);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 267, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID)
//                .setContentTitle(title)
//                .setContentText(body)
                .setSmallIcon(R.drawable.ic_launcher_background)
                .setPriority(NotificationCompat.PRIORITY_HIGH)
                .setStyle(new NotificationCompat.BigTextStyle().setSummaryText("summary").setBigContentTitle(title).bigText(body))
                .setContentIntent(pendingIntent)
                .setAutoCancel(true)
                .build();

        NotificationManagerCompat.from(this).notify(new Random().nextInt(), notification);


    }

}

这是我调用通知的代码：

package com.example.geofencing1;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.util.Log;
import android.widget.Toast;

import com.google.android.gms.location.Geofence;
import com.google.android.gms.location.GeofencingEvent;
import com.google.android.gms.maps.model.LatLng;

import java.util.List;

public class GeofenceBroadcastReceiver extends BroadcastReceiver {

    private static final String TAG = "GeofenceBroadcastReceiv";

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        // Toast.makeText(context, "Geofence triggered...", Toast.LENGTH_SHORT).show();

        NotificationHelper notificationHelper = new NotificationHelper(context);

        GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);

        if (geofencingEvent.hasError()){
            Log.d(TAG, "onReceive: Error receiving geofence event...");
            return;
        }


        List<Geofence> geofenceList = geofencingEvent.getTriggeringGeofences();
        for (Geofence geofence: geofenceList) {
            Log.d(TAG, "onReceive: " + geofence.getRequestId());
        }
//        Location location = geofencingEvent.getTriggeringLocation();
        int transitionType = geofencingEvent.getGeofenceTransition();

        switch (transitionType) {
            case Geofence.GEOFENCE_TRANSITION_ENTER:
                Toast.makeText(context, "GEOFENCE_TRANSITION_ENTER", Toast.LENGTH_SHORT).show();
                notificationHelper.sendHighPriorityNotification("GEOFENCE_TRANSITION_ENTER", "", MapsActivity.class);
                break;
            case Geofence.GEOFENCE_TRANSITION_DWELL:
                Toast.makeText(context, "GEOFENCE_TRANSITION_DWELL", Toast.LENGTH_SHORT).show();
                notificationHelper.sendHighPriorityNotification("GEOFENCE_TRANSITION_DWELL", "", MapsActivity.class);
                break;
            case Geofence.GEOFENCE_TRANSITION_EXIT:
                Toast.makeText(context, "GEOFENCE_TRANSITION_EXIT", Toast.LENGTH_SHORT).show();
                notificationHelper.sendHighPriorityNotification("GEOFENCE_TRANSITION_EXIT", "", MapsActivity.class);
                break;
        }


    }
}
