Android Notification 版本适配方案

Notification 介绍见：https://developer.android.com/reference/android/app/Notification.html



Android api 一直对通知栏进行升级！ 包括7.0继续改善快捷通知栏，接下来介绍下通知栏不同版本的兼容适配.



**Android  JELLY_BEAN(16) 通知可以直接new Notification()**



     Notification notification = new Notification();

     notification.icon = android.R.drawable.stat_sys_download_done;

     notification.flags |= Notification.FLAG_AUTO_CANCEL;

    // 设置点击事件的PendingIntent

     notification.setLatestEventInfo(mContext, aInfo.mFilename, contentText, pendingIntent);



**Android .LOLLIPOP_MR1(22) 通知可以通过Notification.Builder（）**



    Notification notification = new Notification.Builder(mContext)

     .setAutoCancel(false)

     .setContentIntent(pi)// 设置pendingIntent

     .setSmallIcon(android.R.drawable.stat_sys_download_done)

     .setWhen(System.currentTimeMillis())

     .build();

    

**Android .LOLLIPOP_MR1(22)以上 也就从6.0开始  只能通过new NotificationCompat.Builder(mContext)**



    Notification notification = new NotificationCompat.Builder(mContext)

     .setContentTitle(aInfo.mFilename)

     .setContentText(contentText)

     .setSmallIcon(android.R.drawable.stat_sys_download_done)

     .setContentIntent(pi)// 设置pendingIntent

     .build();



# 综合代码： #



     //准备intent

     Intent intent = new Intent();

      String action = "com.skay.myapp.action";

     intent.setAction(action);

    

     //notification

      Notification notification = null;

      String contentText;

      // 构建 PendingIntent

      PendingIntent pi = PendingIntent.getActivity(mContext, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);

     //版本兼容

     

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {

       notification = new Notification();

     notification.icon = android.R.drawable.stat_sys_download_done;

     notification.flags |= Notification.FLAG_AUTO_CANCEL;

     notification.setLatestEventInfo(mContext, aInfo.mFilename, contentText, pi);

    

    } else if (Build.VERSION.SDK_INT >= 23) {

       notification = new NotificationCompat.Builder(mContext)

     .setContentTitle(aInfo.mFilename)

     .setContentText(contentText)

     .setSmallIcon(android.R.drawable.stat_sys_download_done)

     .setContentIntent(pi).build();

    

    } else if ( Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN &&

      Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP_MR1) {

       notification = new Notification.Builder(mContext)

     .setAutoCancel(false)

     .setContentIntent(pi)

     .setSmallIcon(android.R.drawable.stat_sys_download_done)

     .setWhen(System.currentTimeMillis())

     .build();

    }

    mNotificationManager.notify(RESULT_ID, notification);
