我遵循了有关使用Android Studio实施Google Maps API的教程，当我发现Place Picker已贬值时，我的进度暂停了。结果，我的应用程序在打开时崩溃。
在本教程中，我已经实现了MapView，缩放功能，中心功能和位置更新请求，并且在实现位置搜索时遇到了问题。
private fun loadPlacePicker() { //creates new builder for an intent to start the Place Picker UI
val builder = PlacePicker.IntentBuilder()
try {
startActivityForResult(builder.build(this@MapsActivity), PLACE_PICKER_REQUEST)
} catch (e: GooglePlayServicesRepairableException) {
e.printStackTrace()
} catch (e: GooglePlayServicesNotAvailableException) {
e.printStackTrace()
}
}
我相信预期的结果将是实现一个浮动操作栏，该栏可用于搜索位置。在代码上，PlacePicker被删除，并显示一条消息：“'PlacePicker'已弃用。在Java中已弃用”。
显示以下错误，我不知道这意味着什么：

答案 0 :(得分：0)
基于文档：
已于2019年1月29日弃用了Place Picker（Android，iOS）。 此功能将于2019年7月29日关闭，并且不再 在该日期之后可用。要继续将Place Picker与 在整个弃用期限内放置iOS版v.2.7.0的SDK，请勿 禁用iOS版Places SDK。
请注意，只有2019年1月29日之前的Place Picker用户才可以继续使用Place Picker直到2019年7月29日，因为这是因为只有 Places SDK才能使用Place Picker在GCP Console中启用了iOS / Android版， iOS / Android版Places SDK 现在对新用户不可见。现在，新用户将需要启用Places API才能使用其中Place Selecter现在不可用的移动SDK。
Google目前正在对促使用户使用位置选择器的因素进行审查，如果您有兴趣，可以在问题跟踪器中以issue中提到的形式添加答案。
