为什么Android设备推送通知在Log中可查看，但是通知无法弹出?

1 问题


向Android设备推送消息，从客户端Log已经看到通知内容，为什么并没有通知弹出？

2 解决方案


请按照以下步骤进行排查：

• 检查设备【设置】中是否对测试App做了通知栏弹出的限制，如小米设备，通过【设置】-【应用】-【自定义通知】可指定打开或关闭指定应用的通知弹出；
• 推送老版本SDK对Android 4.2以下版本兼容问题，Android 4.2以下版本系统设备通知可能无法弹出，SDK v2.3.0已将该问题修复。
• 由于部分设备不允许监听系统的广播，可能导致通知栏的通知无法弹出，将AndroidManifest.xml中消息接收receiver只注册以下三个intent-filter：

  1. [backcolor=transparent]   [backcolor=transparent] <!--[backcolor=transparent] [backcolor=transparent] 消息接收[backcolor=transparent] [backcolor=transparent] （用户可自主扩展）[backcolor=transparent] [backcolor=transparent] -->
  2. [backcolor=transparent]  [backcolor=transparent]<[backcolor=transparent]receiver
  3. [backcolor=transparent]   android[backcolor=transparent]:[backcolor=transparent]name[backcolor=transparent]=[backcolor=transparent]".MyMessageReceiver"
  4. [backcolor=transparent]   android[backcolor=transparent]:[backcolor=transparent]exported[backcolor=transparent]=[backcolor=transparent]"false"[backcolor=transparent]>[backcolor=transparent] [backcolor=transparent]<!--[backcolor=transparent] [backcolor=transparent]为保证[backcolor=transparent]receiver[backcolor=transparent]安全，建议设置不可导出，如需对其他应用开放可通过[backcolor=transparent]    android[backcolor=transparent]：[backcolor=transparent]permission[backcolor=transparent]进行限制[backcolor=transparent] [backcolor=transparent]-->
  5. [backcolor=transparent]      [backcolor=transparent]<[backcolor=transparent]intent[backcolor=transparent]-[backcolor=transparent]filter[backcolor=transparent]>
  6. [backcolor=transparent]       [backcolor=transparent]<[backcolor=transparent]action android[backcolor=transparent]:[backcolor=transparent]name[backcolor=transparent]=[backcolor=transparent]"com.alibaba.push2.action.NOTIFICATION_OPENED"[backcolor=transparent] [backcolor=transparent]/>
  7. [backcolor=transparent]      [backcolor=transparent]</[backcolor=transparent]intent[backcolor=transparent]-[backcolor=transparent]filter[backcolor=transparent]>
  8. [backcolor=transparent]      [backcolor=transparent]<[backcolor=transparent]intent[backcolor=transparent]-[backcolor=transparent]filter[backcolor=transparent]>
  9. [backcolor=transparent]       [backcolor=transparent]<[backcolor=transparent]action android[backcolor=transparent]:[backcolor=transparent]name[backcolor=transparent]=[backcolor=transparent]"com.alibaba.push2.action.NOTIFICATION_REMOVED"[backcolor=transparent] [backcolor=transparent]/>
  10. [backcolor=transparent]      [backcolor=transparent]</[backcolor=transparent]intent[backcolor=transparent]-[backcolor=transparent]filter[backcolor=transparent]>
  11. [backcolor=transparent]      [backcolor=transparent]<[backcolor=transparent]intent[backcolor=transparent]-[backcolor=transparent]filter[backcolor=transparent]>
  12. [backcolor=transparent]       [backcolor=transparent]<[backcolor=transparent]action android[backcolor=transparent]:[backcolor=transparent]name[backcolor=transparent]=[backcolor=transparent]"com.alibaba.sdk.android.push.RECEIVE"[backcolor=transparent] [backcolor=transparent]/>
  13. [backcolor=transparent]      [backcolor=transparent]</[backcolor=transparent]intent[backcolor=transparent]-[backcolor=transparent]filter[backcolor=transparent]>
  14. [backcolor=transparent]  [backcolor=transparent]</[backcolor=transparent]receiver[backcolor=transparent]>

  如果是从v2.3.7及以下版本升级到v3.0.0及以上版本的用户，需将<action android:name="org.agoo.android.intent.action.receive" />改为<action android:name="com.alibaba.sdk.android.push.receive" />,否则会接收不到推送。
