如何解决“找不到 com.my.package.urbanairship.provider 的提供商信息”？

Question

我正在尝试使用Urban Airship 和GCM 在我的Android 应用程序中启用推送通知。我使用here 给出的说明创建了一个GCM 帐户，并在Urban Airship 上设置了一个开发应用程序。然后我从here 显示的示例应用程序中复制了代码。

现在当我运行我的应用程序时，我得到了

E/ActivityThread﹕ Failed to find provider info for com.my.package.urbanairship.provider

然后

E/ActivityThread﹕ Failed to find provider info for com.my.package.urbanairship.provider
E/XXXX - UALib﹕ Failed to insert in UrbanAirshipProvider.
java.lang.IllegalArgumentException: Unknown URL content://com.my.package.urbanairship.provider/preferences

我错过了什么？

app/src/main/assets/airshipconfig.properties

developmentAppKey = <my developmentAppKey>
developmentAppSecret = <my developmentAppSecret>
productionAppKey = 
productionAppSecret = 
gcmSender = <my gcmSender>
inProduction = false
# LogLevel is "VERBOSE", "DEBUG", "INFO", "WARN", "ERROR" or "ASSERT"
developmentLogLevel = DEBUG

Answer 1

我没有在您的清单中看到定义的提供程序。你应该有这样的东西：

<provider
    android:name="provider"
    android:authorities="com.my.package.urbanairship.provider"
    android:exported="false"/>
