Android通知setSound无效

Question

在我的针对API 23+的混合Cordova Android应用中,我想使用自定义声音进行通知.为此,我做了以下工作

• 在plugin.xml我声明的应用程序中使用的单个自定义插件的文件中<resource-file src="src/android/res/unysound.mp3" target="res/raw/mysound.mp3" />'.

打开APK作为zip存档我看到mp3文件实际上最终在`res/raw/mysound.mp3'. - 构建通知时,我执行以下操作

    Notification notification = new Notification.Builder(context)
    .setDefaults(0) //turns off ALL defaults
    .setVibrate(vibrate)  /sets to vibrate
    ....
    .setSound(uri).build();

哪里

Uri uri = Uri.parse("android.resource://" + ctxt.getPackageName() + "/raw/mysound.mp3");

这似乎是我在google网站上发现的一些文章中指出的配方,甚至在SO上的其他帖子中也是如此.然而,当我发出通知时,我听不到预期的声音.我可能做错了什么？

下面的答案没有帮助,因为在我的混合Cordova应用程序与自定义插件尝试构建APK的上下文中引发了一个错误的行 class R not known/found...

Answer 1

以下代码将帮助您:

String CHANNEL_ID="1234";

Uri soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://"+ getApplicationContext().getPackageName() + "/" + R.raw.mysound);

NotificationManager mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);

对于API 26+,您需要添加一些额外的代码,如下所示:

NotificationChannel mChannel;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            mChannel = new NotificationChannel(CHANNEL_ID, Utils.CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
            mChannel.setLightColor(Color.GRAY);
            mChannel.enableLights(true);
            mChannel.setDescription(Utils.CHANNEL_SIREN_DESCRIPTION);
            AudioAttributes audioAttributes = new AudioAttributes.Builder()
                    .setContentType(AudioAttributes.CONTENT_TYPE_NOTIFICATION)
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();
            mChannel.setSound(soundUri, audioAttributes);

            if (mNotificationManager != null) {
                mNotificationManager.createNotificationChannel( mChannel );
            }
    }

一般代码:

 NotificationCompat.Builder status = new NotificationCompat.Builder(getApplicationContext(),CHANNEL_ID);     
                      status.setAutoCancel(true)
                            .setWhen(System.currentTimeMillis())
                            .setSmallIcon(R.drawable.logo)
                            //.setOnlyAlertOnce(true)
                            .setContentTitle(getString(R.string.app_name))
                            .setContentText(messageBody)
                            .setVibrate(new long[]{0, 500, 1000})
                            .setDefaults(Notification.DEFAULT_LIGHTS )
                            .setSound(Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE+ "://" +mContext.getPackageName()+"/"+R.raw.apple_ring))
                            .setContentIntent(pendingIntent)
                            .setContent(views);

                    mNotificationManager.notify(major_id, status.build());

mysound是我的铃声,放在res/raw文件夹下.

注意:你必须只放置没有扩展名的铃声名称,如raw/mysound

对于API 26+,您需要在通知通道上设置声音:

Uri soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://"+ getApplicationContext().getPackageName() + "/" + R.raw.siren);
NotificationManager mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    NotificationChannel mChannel;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            mChannel = new NotificationChannel(Utils.CHANNEL_SIREN_ID, Utils.CHANNEL_SIREN_NAME, NotificationManager.IMPORTANCE_HIGH);
            mChannel.setLightColor(Color.GRAY);
            mChannel.enableLights(true);
            mChannel.setDescription(Utils.CHANNEL_SIREN_DESCRIPTION);
            AudioAttributes audioAttributes = new AudioAttributes.Builder()
                    .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();
            mChannel.setSound(soundUri, audioAttributes);

            if (mNotificationManager != null) {
                mNotificationManager.createNotificationChannel( mChannel );
            }
    }

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, Utils.CHANNEL_SIREN_ID)
            .setSmallIcon(R.drawable.ic_stat_maps_local_library)
            .setLargeIcon(BitmapFactory.decodeResource(getApplicationContext().getResources(), R.mipmap.ic_launcher))
            .setTicker(title)
            .setContentTitle(contentTitle)
            .setContentText(contentText)
            .setAutoCancel(true)
            .setLights(0xff0000ff, 300, 1000) // blue color
            .setWhen(System.currentTimeMillis())
            .setPriority(NotificationCompat.PRIORITY_DEFAULT);

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
            mBuilder.setSound(soundUri);
    }

    int NOTIFICATION_ID = 1; // Causes to update the same notification over and over again.
    if (mNotificationManager != null) {
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }

Answer 3

1. 尝试清除数据（或全新安装）
2. 再试一次

除非您通过全新安装或清除数据手动进行设置，否则设置将在您首次创建通道时进行设置，然后再进行修改。

Answer 4

您可以在处理通知时调用此方法

    public void playNotificationSound() {
    try {
        Uri alarmSound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE
                + "://" + mContext.getPackageName() + "/raw/notification");
        Ringtone r = RingtoneManager.getRingtone(mContext, alarmSound);
        r.play();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Answer 5

 Notification.Builder builder = new Notification.Builder(context);
    builder.setContentTitle(mTitle);
    builder.setContentText(mContentText);
    builder.setSmallIcon(R.mipmap.ic_launcher);

    builder.setSound(Settings.System.DEFAULT_NOTIFICATION_URI);
    builder.setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 });
    builder.setDefaults(Notification.DEFAULT_ALL);

用它来处理声音，我希望它能解决您的问题，干杯！
