所以我有一个应用程序，它包含所有 google play 服务.. 但我仍然收到错误和强制崩溃.. 提前致谢。 MainActivity.java

        public class MainActivity extends FragmentActivity {
        SupportMapFragment mMap;
        GoogleMap googleMap;
        TabHost tabHost;

        @SuppressLint("SetJavaScriptEnabled")
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            // Load Webview
            WebView myWebView = (WebView) findViewById(R.id.webView1);
            WebSettings webSettings = myWebView.getSettings();
            webSettings.setJavaScriptEnabled(true);
            myWebView.setWebViewClient(new WebViewClient());
            myWebView.loadUrl("http://www.salespharma.com/sptouch/msplogin.htm");
            // Remove ActionBar
            getActionBar().hide();
            // Setup the tabhost
            tabHost = (TabHost) findViewById(R.id.tabHost);
            tabHost.setup();

            TabSpec spec1 = tabHost.newTabSpec("SPtouch");
            spec1.setContent(R.id.tab1);
            spec1.setIndicator("SPtouch");

            TabSpec spec2 = tabHost.newTabSpec("GeoLocation");
            spec2.setIndicator("GeoLocation");
            spec2.setContent(R.id.tab2);

            tabHost.addTab(spec1);
            tabHost.addTab(spec2);
            mMap = (SupportMapFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.map);

            googleMap = mMap.getMap();
            // mMap = ((MapFragment)
            // getFragmentManager().findFragmentById(R.id.map)).getMap();
            // Flip view

        }

        public void LoadActivity() {
            Intent startNewActivityOpen = new Intent(MainActivity.this,
                    Settings.class);
            startActivityForResult(startNewActivityOpen, 0);
        }

        public boolean onOptionsItemSelected(MenuItem item) {
            // Handle item selection
            switch (item.getItemId()) {
            case R.id.action_settings:
                LoadActivity();
                return true;
            default:
                return super.onOptionsItemSelected(item);
            }
        }

        @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;
        }

         }

【问题讨论】：

标签： android xml eclipse google-play-services

【解决方案1】：

这里有几个指针：

在您的 AndroidManifest.xml 中：

<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="***********************************" />

应该位于<application>标签内
您的项目经理中没有google-play-services_lib，这是我的设置：

请注意，我有google-play-services_lib.jar 和google-play-services.jar，您需要将Google Play Services Library 导入您的工作区，确保项目已打开，然后将其导入为其他项目的库

祝你好运！！

This Link 将为您提供 Android API v2 的分步快速入门指南，对于您的情况，我认为您只需要按照从第 1 步到第 4 步的指南进行操作 :)

现在，我建议你对这个问题做更多的研究，方法如下：

尝试在您的应用程序中仅显示地图，如果地图显示，则您的布局声明有错误。如果应用程序崩溃，那么您有库引用错误。
如果出现引用错误，请尝试创建一个新项目，将google-play-services_lib 导入到您的项目中，然后尝试先显示地图。当它显示时，修改您的代码以匹配您在此处拥有的当前代码。

祝你好运：D

感谢您的回复，我注意到您没有 android 私有依赖项。如何删除我拥有的那个，并将所有 JARS 移动到 android 依赖项......再次感谢。一张图告诉你我的进步link
不用担心android private dependencies，尝试从构建路径中删除google play services 库，然后使用我的方法重新插入：D
我编辑了我的答案，请检查那里的链接，它将为您提供分步教程，请按照 1-4 中的步骤操作
那是我所遵循的原始指南。好吧，Google-play-services-lib.jar 在那里，Google-play-services.jar 不在。
在将google-play-services_lib 添加为库后尝试清理您的项目，它工作了吗？
