未能找到用户0的提供者null；期望为此权限找到有效的ContentProvider Android Oreo

Question

我面临两个相互关联的问题，我在Android Oreo设备中面临以下问题，

     java.lang.RuntimeException: Error receiving broadcast Intent { act=com.example.bluetooth.le.ACTION_REMOTE_RSSI_UPDATED flg=0x10 (has extras) } in com.linka.linkaapikit.module.widget.LockGattUpdateReceiver$1@762cfd9

    at android.content.ContentResolver.notifyChange(ContentResolver.java:1970)
    at com.activeandroid.Model.save(Model.java:162)

此后，我找到了以下解决方案，

在Android清单中添加

 <provider
        android:name="com.activeandroid.content.ContentProvider"
        android:authorities="com.myapp"
        android:enabled="true"
        android:exported="false"
        />

但是在添加这一行之后，我又遇到了另一个问题，

 java.lang.IncompatibleClassChangeError: Superclass org.apache.http.params.BasicHttpParams of org.apache.http.params.SyncBasicHttpParams is declared final (declaration of 'org.apache.http.params.SyncBasicHttpParams' appears in /data/app/com.kolonishare-6KsxqUHOK_Q45cGI0D0bHg==/base.apk:classes16.dex)

我清理并重建项目，使重新启动无效，但出现相同的错误。

您需要在其中放入xml

<provider android:name="com.activeandroid.content.ContentProvider"
    android:authorities="${applicationId}.fileprovider"
    android:enabled="true"
    android:exported="false" />
