Android通知setSound无法正常工作 [英] Android notification setSound is not working
问题描述
在面向API 23+的混合式Cordova Android应用中,我想使用自定义声音进行通知.为此,我已完成以下操作
In my hybrid Cordova Android app targeting API 23+ I want to use a custom sound for notifications. To that end I have done the following
- 在我在应用程序中使用的单个自定义插件的
plugin.xml
文件中,声明了<resource-file src="src/android/res/unysound.mp3" target="res/raw/mysound.mp3" />'
.
- In
plugin.xml
file for the single custom plugin I use in the app I declare<resource-file src="src/android/res/unysound.mp3" target="res/raw/mysound.mp3" />'
.
打开APK作为zip存档,我发现mp3文件实际上以`res/raw/mysound.mp3结尾. -建立通知时,请执行以下操作
Opening the APK as a zip archive I see that the mp3 file has in fact ended up in `res/raw/mysound.mp3'. - When building the notification I do the following
Notification notification = new Notification.Builder(context)
.setDefaults(0) //turns off ALL defaults
.setVibrate(vibrate) /sets to vibrate
....
.setSound(uri).build();
其中
Uri uri = Uri.parse("android.resource://" + ctxt.getPackageName() + "/raw/mysound.mp3");
这似乎是我在谷歌搜索的地方甚至在SO的其他主题中找到的许多文章中指出的配方.但是,当我发出通知时,我听不到预期的声音.我可能做错了什么?
This appears to be the recipe indicated in a number of articles I find on a spot of googling and even in other threads on SO. And yet, when I issue a notification I do not hear the expected sound. What might I be doing wrong?
下面的答案无济于事,因为在我的带有自定义插件的混合式Cordova应用程序的上下文中,尝试构建APK时会沿着class R not known/found...
The answer below does not help since in the context of my hybrid Cordova app with a custom plugin attempting to build the APK throws up an error along the lines of class R not known/found...
推荐答案
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);
//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是我的手机铃声,它位于res/raw文件夹下.
where mysound is my ringtone which is put under res/raw folder.
注意:您只需输入铃声名称,无需扩展名即可,例如 raw/mysound
Note: you have to only put name of ringtone without extension like raw/mysound
