在Android Studio上，makeGooglePlayServicesAvailable在真实设备上导致应用崩溃

Question

我正在一个真实设备上运行Android 4.2.2上的makeGooglePlayServicesAvailable，但它会崩溃，并显示下面的堆栈跟踪。我不知道这是否是一个makeGooglePlayServicesAvailable问题还是来自错误消息的其他问题？在具有更高Android操作系统的模拟器上，相同的代码可以正常工作。

public class EventsActivity extends BaseActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);


        GoogleApiAvailability googleApiAvailability =  GoogleApiAvailability.getInstance();

        int success = googleApiAvailability.isGooglePlayServicesAvailable(this);

        if(success != ConnectionResult.SUCCESS)
        {
            googleApiAvailability.makeGooglePlayServicesAvailable(this);
        }

        super.onCreate(savedInstanceState);
        setContentView(R.layout.drawer);
    }

错误

问题是你正在从一个已销毁的活动中调用它。除此之外，如果没有代码，我们无法提供更多信息。 - Gabe Sechan

添加了代码，就像我说的那样，它在启动时运行，并不会破坏任何东西。 - Mike Flynn

尝试在super.onCreate()之后调用它。在此之前，Activity并没有真正初始化。 - Gabe Sechan

哈，就是这样，不知道为什么在我的模拟器上无法工作，但现在看起来可以了。 - Mike Flynn

Answer 1

在调用 super.onCreate() 之后使用它解决了该问题。
