问题描述
我实现了PlacePicker.IntentBuilder UI到我的应用程序。在很长的，它的工作没有问题，但现在只要用户界面出现后，它会关闭和IM不知道为什么。疯狂的事是在看logcat的它不会崩溃或导致任何异常，所以我不知道问题是什么。这是一个创建并调用它的类。
I implemented the PlacePicker.IntentBuilder UI into my application. For the longest it worked with no problem but now as soon as the UI appears, it closes and im not sure why. The crazy thing is looking at the logcat it doesn't crash or cause any exceptions so I don't know what the issue is. This is the class that creates and calls it.

这是logcat的，当我到达这个阶级和preSS的按钮，呼叫PlacePlace.IntentBuilder
This is the logcat when I get to this class and press the button the calls the PlacePlace.IntentBuilder

是否有人可以帮助我。
推荐答案
我有同样的问题。请确保您启用的地方为Android API并不仅仅是的地方API中的开发者控制台。因为它不是一个受欢迎的API（还）; 为Android API的地方将不会在认证/ API的原料药及放出现。你将不得不使用API的搜索框进行搜索。
I was having the same issue. Make sure you enable "Places API for Android" and not just "Places API" in the Developer Console. "Places API for Android" will not show up under "APIs & Auth/APIs" because it isnt a popular API (yet). You will have to search for it using the API search box.
