Question

我在我的Android应用中使用GoogleApiClient，并在我的应用恢复时遇到崩溃。

代码如下所示：

MainActivity签名：

public class MainActivity : AppCompatActivity, GoogleApiClient.IOnConnectionFailedListener, Android.Gms.Location.ILocationListener

OnCreate中

protected override async void OnCreate(Bundle bundle)
{
    App.Initialize();
    base.OnCreate(bundle);

    SetContentView(Resource.Layout.Main);

    await InitializeGoogleApis();
}

Google API初始化

private async Task InitializeGoogleApis()
{
    // Construct api client and request for required api's
    googleApiClientBuilder = new GoogleApiClient.Builder(this)
       .AddApi(LocationServices.API)
       .EnableAutoManage(this, this);

    // Connect to google play services
    googleApiClient = await googleApiClientBuilder
        .BuildAndConnectAsync();

    // Request location api and set common properties
    googleLocationRequest = new LocationRequest()
        .SetPriority(LocationRequest.PriorityHighAccuracy)
        .SetInterval(1000)
        .SetFastestInterval(1000);

    // Set location changed listener
    await LocationServices.FusedLocationApi.RequestLocationUpdatesAsync(googleApiClient, googleLocationRequest, this);
}

OnResume和OnDestroy ：

protected override void OnResume()
{
    base.OnResume();
}

protected override async void OnDestroy()
{
    base.OnDestroy();

    if (googleApiClient != null)
        await LocationServices.FusedLocationApi.RemoveLocationUpdatesAsync(googleApiClient, this);
}

我已启用所有例外但is no exception description

当我尝试恢复时，应用程序总是崩溃。当它崩溃时，它会被放入后台，当我再次尝试恢复时，它会完美运行。

好的，我找到了一个讨厌的方法，我把所有的实现都保持不变，只是将这些功能添加到我的主要活动中

protected override void OnStop()
{
    base.OnStop();

    if (googleApiClient != null)
    {
        LocationServices.FusedLocationApi.Dispose();
        googleApiClient.StopAutoManage(this);
        googleApiClient.Disconnect();
        googleApiClient.Dispose();
        googleApiClient = null;
    }
}

protected override async void OnRestart()
{
    base.OnRestart();
    await InitializeGoogleApis();
}

我强行停止GoogleApiClient并在我的OnRestart函数中重新初始化它。所以基本上解决了我的问题。
