Question

我正在尝试选择自动填充表单并绘制一个路径，当我从自动填充中选择一个地方时，应用程序崩溃了。请看

---------崩溃的开始

E / AndroidRuntime：致命异常：主要程序：com.saoutimohamed.tewsila，PID：5924 java.lang.IllegalStateException：没有包含的点在com.google.android.gms.common.internal.Preconditions.checkState（未知来源：8）在com.google.android.gms.maps.model.LatLngBounds $ Builder.build（未知来源：10）在com.saoutimohamed.tewsila.WelcomeDriver $ 4.onResponse（WelcomeDriver.java:271） at retrofit2.ExecutorCallAdapterFactory $ ExecutorCallbackCall $ 1 $ 1.run（ExecutorCallAdapterFactory.java:70）在android.os.Handler.handleCallback（Handler.java:789）在android.os.Handler.dispatchMessage（Handler.java:98）在android.os.Looper.loop（Looper.java:164）在android.app.ActivityThread.main（ActivityThread.java:6938） at java.lang.reflect.Method.invoke（Native Method）在com.android.internal.os.Zygote $ MethodAndArgsCaller.run（Zygote.java:327）在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:1374）申请已终止。

logcat并告诉我我的代码有什么问题

这是代码

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

在logcat中没有响应的行是（LatLngBounds bounds = builder.build（）;）

我遇到了同样的问题，因此将其删除 requestApi中的“ + getResources（）。getString（R.string.google_direction_api）”部分。 Perfectlr为我工作。但是我不知道原因。

requestApi = "https://maps.googleapis.com/maps/api/directions/json?" +
                "mode=driving&" +
                "transit_routing_preference=less_driving&" +
                "origin=" + Common.mLastLocation.getLatitude() + "," + Common.mLastLocation.getLongitude() + "&" +
                "destination=" + lat+","+lng + "&" +
                "key=";
