要解决Android通知被取消而没有显示且没有错误信息的问题,可以尝试以下方法:
// 创建通知渠道
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
String channelId = "your_channel_id";
CharSequence channelName = "your_channel_name";
String channelDescription = "your_channel_description";
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel(channelId, channelName, importance);
channel.setDescription(channelDescription);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.createNotificationChannel(channel);
// 设置通知渠道ID
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId);
// 构建通知
// ...
// 显示通知
notificationManager.notify(notificationId, builder.build());
} else {
// 在Android 7.1及更低版本中直接显示通知
// ...
}
// 检查通知权限
private boolean checkNotificationPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
return notificationManager.getNotificationChannel(channelId) != null &&
notificationManager.getNotificationChannel(channelId).getImportance() != NotificationManager.IMPORTANCE_NONE;
} else {
// 在Android 7.1及更低版本中默认具有通知权限
return true;
}
}
// 设置通知为持久通知
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
.setOngoing(true);
// 构建通知
// ...
// 显示通知
notificationManager.notify(notificationId, builder.build());
// 设置通知的优先级为最高
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
.setPriority(NotificationCompat.PRIORITY_HIGH);
// 构建通知
// ...
// 显示通知
notificationManager.notify(notificationId, builder.build());
通过以上方法,您可以解决Android通知被取消而没有显示且没有错误信息的问题。请根据您的具体需求选择适当的解决方法。
