Android 前台服务

添加权限

<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

创建前台服务

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
    NotificationChannel channel = new NotificationChannel("Example","Example", NotificationManager.IMPORTANCE_HIGH);
    ((NotificationManager) getSystemService(NOTIFICATION_SERVICE)).createNotificationChannel(channel);
}
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "Example");
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setContentTitle("Example");
builder.setContentText("Running");
startForeground(1, builder.build());

前台服务需要创建一个channel用来显示在通知栏

关闭服务

stopForeground(true);
