Android8.0及以上通知适配和自定义通知声音

在最近的项目开发中遇到了一个问题，8.0以上的通知无法正常显示和自定义的通知提示音无效的问题，今天特此记录一下，希望能够避免大家踩坑

由于Android 8.0 系统，Google为了提高用户体验，方便用户管理通知信息，同时也提高了通知到达率引入通知渠道。导致之前正常的写法无法直接使用

首先在Application中创建NotificationManager统一管理通知

由于NotificationChannel一旦被创建后无法修改 如果需要自定义提示音 需要提前吧所需的提示音配置完毕 然后指定通知渠道 发送时根据通知渠道即可发送

代码如下：

public class app extends Application {public static NotificationManager notificationChannelManager;public app() {super();}@Overridepublic void onCreate() {super.onCreate();notificationChannelManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {AudioAttributes att = new AudioAttributes.Builder().setUsage(AudioAttributes.USAGE_NOTIFICATION).setContentType(AudioAttributes.CONTENT_TYPE_SPEECH).build();Uri huifang = Uri.parse("android.resource://" + this.getPackageName() + "/" + R.raw.huifang);Uri new_client = Uri.parse("android.resource://" + this.getPackageName() + "/" + R.raw.new_client);Uri new_dynamic = Uri.parse("android.resource://" + this.getPackageName() + "/" + R.raw.new_dynamic);Uri new_task = Uri.parse("android.resource://" + this.getPackageName() + "/" + R.raw.new_task);NotificationChannel huifangcannel = new NotificationChannel("huifang", "回访提示音", NotificationManager.IMPORTANCE_HIGH);NotificationChannel new_clientcannel = new NotificationChannel("new_client", "新客户提示音", NotificationManager.IMPORTANCE_HIGH);NotificationChannel new_dynamiccannel = new NotificationChannel("new_dynamic", "新动态提示音", NotificationManager.IMPORTANCE_HIGH);NotificationChannel new_taskcannel = new NotificationChannel("new_task", "新任务提示音", NotificationManager.IMPORTANCE_HIGH);huifangcannel.setSound(huifang, att);new_clientcannel.setSound(new_client, att);new_dynamiccannel.setSound(new_dynamic, att);new_taskcannel.setSound(new_task, att);notificationChannelManager.createNotificationChannel(huifangcannel);notificationChannelManager.createNotificationChannel(new_clientcannel);notificationChannelManager.createNotificationChannel(new_dynamiccannel);notificationChannelManager.createNotificationChannel(new_taskcannel);}}
}

发送通知

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {showNotification("huifang");} else {showTongzhi();}

首先判断是API是否高于8.0 如果高于则使用通知渠道来发送通知 否则则使用普通通知

完整代码如下

    private void showTongzhi() {Intent intent = new Intent(MainActivity.this, Main2Activity.class);PendingIntent pi = PendingIntent.getActivity(MainActivity.this, 0, intent, 0);Notification notification = new NotificationCompat.Builder(MainActivity.this,"").setContentTitle("这是测试通知标题")  //设置标题.setContentText("这是测试通知内容") //设置内容.setWhen(System.currentTimeMillis())  //设置时间.setSmallIcon(R.mipmap.ic_launcher)  //设置小图标  只能使用alpha图层的图片进行设置.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))   //设置大图标.setAutoCancel(true).setContentIntent(pi).build();app.notificationChannelManager.notify(index, notification);index++;}/** 简单的发送通知*/@SuppressLint("NewApi")@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)private void showNotification(String qudaoid) {Intent intent = new Intent(MainActivity.this, Main2Activity.class);PendingIntent pi = PendingIntent.getActivity(MainActivity.this, 0, intent, 0);NotificationCompat.Builder builder = new NotificationCompat.Builder(MainActivity.this, qudaoid);builder.setContentTitle("title1111"+qudaoid).setContentText("content1111"+qudaoid).setSmallIcon(R.mipmap.ic_launcher).setContentIntent(pi).setAutoCancel(true);Notification notification = builder.build();app.notificationChannelManager.notify(index, notification);index++;}
