在我的针对 API 23+ 的混合 Cordova Android 应用程序中，我想使用自定义声音进行通知。为此，我做了以下工作
plugin.xml<resource-file src="src/android/res/unysound.mp3" target="res/raw/mysound.mp3" />'以 zip 存档形式打开 APK，我发现 mp3 文件实际上已位于“res/raw/mysound.mp3”中。 - 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");
这似乎是我在谷歌搜索上找到的许多文章中指出的食谱，甚至是在其他线程中。然而，当我发出通知时，我没有听到预期的声音。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 应用程序的上下文中，尝试构建 APK 的自定义插件会引发类似
class R not known/found...下面的代码可以帮助你：
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);
//For API 26+ you need to put some additional code like below:
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_SONIFICATION)
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.build();
mChannel.setSound(soundUri, audioAttributes);
if (mNotificationManager != null) {
mNotificationManager.createNotificationChannel( mChannel );
}
}
//General code:
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());
其中 mysound 是我的铃声，放在 res/raw 文件夹下。
注意：您必须只输入铃声名称而不带扩展名，例如raw/mysound
注意：在 Android Oreo 中，您必须更改频道 ID 才能使更改生效。在 Oreo 版本之前，使用“.setDefaults()”会阻止自定义声音的播放。
这些设置是在您第一次创建频道时设置的，然后不会修改，除非您通过全新安装或清除数据手动进行设置。
有关这方面的更多信息，请阅读此处的最佳答案： 即使我没有设置声音，Android Oreo 通知也会不断发出声音。在旧版本上，完美运行
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());
}
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();
}
}
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，我希望它能解决你的问题，干杯！
用它来设置声音
Uri defaultSoundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + mContext.getPackageName() + "/raw/mysound");
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(mContext)
.setContentIntent(mainPIntent)
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), R.mipmap.ic_launcher))
.setContentTitle("" + title)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentText("" + body);
NotificationManager mNotificationManager =
(NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(title, NOTIFICATION_ID, mBuilder.build());
您正在访问资源子文件夹中的声音
将 uri 的来源更改为
Uri uri = Uri.parse("android.resource://" + context.getPackageName() + "/" + R.raw.siren);
对于默认声音，请使用：
notification.defaults |= Notification.DEFAULT_SOUND;
我不确定，但我认为问题是你做错了方法
"/raw/mysound.mp3Uri uri = Uri.parse("android.resource://" + ctxt.getPackageName() + "/raw/mysound.mp3");
首先在清单中添加权限：
uses-permission android:name="android.permission.VIBRATE" />Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
mBuilder.setSound(alarmSound);
振动：
mBuilder.setVibrate(new long[] { 1000, 1000});
对于自定义声音，请将 mp3 文件放在此路径中：
Res\raw\sound.mp3Notification notification = builder.build();
notification.sound = Uri.parse("android.resource://"
+ context.getPackageName() + "/" + R.raw.sound);
这在另一个答案的评论中提到过，但我认为值得重复。
