我正在制作一个应用程序，它利用广播接收器获取手机中收到的特定短信息。广播接收器要获取的短信息包含“！test！”在它们中，然后通过HTTP帖子发送到服务器。 此程序在某些手机上正常运行，，而在其他手机上则（虽然有时会这样）。
问题在于广播接收器未被激活。根据我最近进行的研究，当具有较高优先级的广播接收器首先获得sms广播然后中止它，阻止它被传送到其他电话时，似乎会出现这个问题。 一些解决方案提供了将intent filter的优先级设置为999或1000的位置。但是这并没有最终解决问题。
此外，我已经阅读了从Android 4.4及以上版本中止播放是不允许的，虽然我似乎仍然面临着类似的Android版本问题。
尽管我知道这与Android操作系统存在的一些故障本质上更相关，但为方便起见，我提供了一些代码片段。 我想知道是否有某种方法可以解决这个问题。如果没有，那么需要考虑的建议是什么？
在on create方法中以编程方式注册接收器。
registerReceiver(smsreceiver, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
收到程序：
private BroadcastReceiver smsreceiver = new BroadcastReceiver()

在android manfiest.xml中定义接收器：
<receiver android:name=".smsreceiver">
<intent-filter android:priority="999">
</intent-filter>
答案 0 :(得分：0)
将清单更改为
<receiver
android:name=".YourSMSReceiverClass"
android:exported="true">
<intent-filter android:priority="999">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
