Question

我想在Android应用中实施Google Map。我还按照Google控制台api的所有步骤操作。但在运行时，我的应用程序崩溃并得到有关片段的错误，我不明白。我还在app中添加了google play服务库。有人请帮助我。谢谢。提前感谢。

这是我的日志信息。

这是活动代码

import com.google.android.gms.maps.SupportMapFragment;

    // Google Map
    private GoogleMap googleMap;
   //
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        try {
            // Loading map
            initilizeMap();

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

    }

    /**
     * function to load map. If map is not created it will create it for you
     * */
    private void initilizeMap() {
        if (googleMap == null) {
            googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

            if (googleMap == null) {
                Toast.makeText(getApplicationContext(),
                        "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                        .show();
            }
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        initilizeMap();

Answer 1

你应该

  <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

在<application>

中的manifest.xml标记中

Answer 2

您应该在Manifest.xml文件中添加此权限

<permission
    android:name="com.example_map.demomap.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

<uses-permission android:name="com.example_map.demomap.permission.MAPS_RECEIVE" />

并在<meta-data>

中添加此<application>

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

有关详细信息，请参阅this tutorial.
