android - Android教程上的Google Maps问题

Question

大家好，我一直在尝试遵循Google在其开发人员网站上使用Android中的Google Maps的教程。不用说，我无法使事情正常运行，并且它有多个错误。因此，我从Youtube切换到一个，这也给我带来了错误。我要做的就是绘制 map 。我无法使用的错误发布在下面。我真的希望你们能给我一些提示。任何帮助深表感谢。

人们还注意到，每次遇到问题时，我都会用Google搜索并尝试多次“修复”。因此，这将导致代码中的任何不一致。

错误:

Gradle: Execution failed for task ':GoogleMapsDemoV2:compileDebug'.

Compilation failed; see the compiler error output for details.

无论如何，这是我所有的代码...

主要 Activity

package com.example.googlemapsdemov2;

import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.os.Build;

public class MainActivity extends ActionBarActivity {

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

        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.container, new PlaceholderFragment())
                    .commit();
        }
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        switch (item.getItemId()) {
            case R.id.action_settings:
                return true;
        }
        return super.onOptionsItemSelected(item);
    }

    /**
     * A placeholder fragment containing a simple view.
     */
    public static class PlaceholderFragment extends Fragment {

        public PlaceholderFragment() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_main, container, false);
            return rootView;
        }
    }

}

Answer 1

在AndroidManifest.xml中的MAP_KEY行之前添加以下两行

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