Android studio 使用? ?targetSdkVersion 28? 在Android系統(tǒng)大于等于8.0的時候，通知不顯示bug解決方法：

?

1、修改appcompat版本，如果是小于v27

改為

implementation 'com.android.support:appcompat-v7:27.1.1'

2、添加依賴

compile 'com.github.lovetuzitong:MultiImageSelector:1.2'

3、添加如果系統(tǒng)版本大于等于 8.0 設置NotificationChannel代碼

NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {NotificationChannel channel = new NotificationChannel("com.tianxinyw.mapclient.liteapp",TAG,NotificationManager.IMPORTANCE_DEFAULT);mNotificationManager.createNotificationChannel(channel);}

4、builder添加通道setChannelId

Notification.Builder builder = new Notification.Builder(this);

?

builder.setChannelId("com.tianxinyw.mapclient.liteapp")

?

import static me.nereo.multi_image_selector.MultiImageSelectorFragment.TAG;

附：

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(APPlocation.getTotalContext()); NotificationManager mNotificationManager = (NotificationManager) APPlocation.getTotalContext().getSystemService(Context.NOTIFICATION_SERVICE);if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {NotificationChannel channel = new NotificationChannel("com.tianxin.service2thread",TAG,NotificationManager.IMPORTANCE_DEFAULT);mNotificationManager.createNotificationChannel(channel);}mBuilder.setChannelId("com.tianxin.service2thread"); mBuilder.setContentText("內(nèi)容"); Intent notificationIntent = new Intent(this, TwoActivity.class); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,notificationIntent, 0); mBuilder.setContentIntent(pendingIntent); mBuilder.setSmallIcon(R.mipmap.ic_launcher); mNotificationManager.notify(1, mBuilder.build());
