android - Google Play服务版本过时会不会让应用无法运行？

标签 android google-maps nullpointerexception google-play-services

我正在开发一个简单的应用程序来显示 map 。为此，我正在真实设备上测试我的应用程序:Samsung Galaxy Europa (Android 2.2)。不幸的是，我的应用程序被强制关闭/崩溃，并在 logcat 中查看了很多错误(我提到了我的代码)。我按照规则包含了 google_play_services_lib 但没有成功。是的，我已经抓取了这里提到的所有解决方案，例如:

  1. Solution 1 - Google play services out of date
  2. Solution 2 - Google play services out of date
  3. Solution 3 - Google play services out of date
  4. Solution 4 - Google play services out of date
  5. Solution 5 - Google play services out of date
  6. Solution 6 - Google play services out of date
  7. Solution 7 - Null pointer exception calling fragment

但是将这些从许多其他解决方案中应用出来并没有取得成果。而且我的应用程序仍在崩溃。 我什至在在线 Manymo 模拟器上测试了我的应用程序，但我的应用程序也在模拟器上崩溃了。 是否只有我的 google play 服务版本导致我的应用程序无法运行或其他原因？我将把我的代码和其他所有内容放在一起，这样你们就可以看看挖掘出来根本原因。

MainActivity.java

package com.example.googlev2map;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        GoogleMap googleMap;
        googleMap = ((SupportMapFragment)(getSupportFragmentManager().findFragmentById(R.id.map))).getMap();
        LatLng latLng = new LatLng(-33.796923, 150.922433);

        googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        googleMap.addMarker(new MarkerOptions()
                .position(latLng)
                .title("My Spot")
                .snippet("This is my spot!")
                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));


        //  googleMap.getUiSettings().setCompassEnabled(true);
      //  googleMap.getUiSettings().setZoomControlsEnabled(true);
       // googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 10));

    }


}

最佳答案

由于您的设备是 2.2，因此您不能使用任何高于 3.2 的 Google Play 服务版本(我相信这是对 froyo 停止支持的地方)。

您使用的是最新版本的 google play 服务，它不适用于 2.2

您需要在 SDK 管理器中下载并使用 Google Play Services for Froyo
