Notification.setSound() 不适用于 proguard

Question

我遇到了包括通知库在内的 proguard 问题。如果启用了 proguard，我将听不到通知声音。我找不到哪个库有问题。

app/build.gradle：

实现 'com.google.android.gms:play-services-auth:16.0.1'

实现'com.google.android.gms:play-services-gcm:16.0.0'

实现 'com.google.firebase:firebase-core:16.0.7'

实现 'com.google.firebase:firebase-messaging:17.3.4'

实现'com.crashlytics.sdk.android:crashlytics:2.9.8'

实现'com.android.support:appcompat-v7:28.0.0'

实现 'com.android.support:support-v13:28.0.0'

实现 'com.android.support:design:28.0.0'

实现 'com.android.support:recyclerview-v7:28.0.0'

实现'com.android.support:cardview-v7:28.0.0'

我的保镖：

    protected Object[][] getContents(); }

    public <init>(android.content.Context); }
-keep public class * extends android.support.design.widget.CoordinatorLayout.Behavior { *; }
-keep public class * extends android.support.design.widget.ViewOffsetBehavior { *; }

代码：

    Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notification);
    AudioAttributes attributes = new AudioAttributes.Builder()
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                   .setContentType(AudioAttributes.CONTENT_TYPE_SPEECH)
                    .build();

    // over android 8.0
    NotificationChannel mChannel = new NotificationChannel(Constants.MISSED_CALL, getString(R.string.notification), NotificationManager.IMPORTANCE_HIGH);

    mChannel.setSound(uri, attributes);
    getNotificationManager().createNotificationChannel(mChannel);

    // < 8.0
    android.app.Notification notification = builder
                    .setCategory(NotificationCompat.CATEGORY_CALL)
                    .setSound(uri)
                    .setStyle(setNotificationList(notificationList))
                    .build();

也许配置proguard来保留通知相关的类和音频类？这是一个部分示例：
