Question

public class MainActivity extends FragmentActivity {

private GoogleMap mMap;

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


private void setUpMapIfNeeded() {
    if (mMap == null) {
        // Try to obtain the map from the SupportMapFragment.
        mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                .getMap();
        // Check if we were successful in obtaining the map.
        if (mMap != null) {
            setUpMap();
        }
    }

}


private void setUpMap() {
    mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));

}


@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
    setUpMapIfNeeded();
}


@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;
}
}

我遇到了这个例外：

Answer 1

试试这个

在Eclipse中转到：

项目 - ＆gt;属性 - ＆gt; Java构建属性

在“订购和导出”标签上，我检查了项目中的“Android私有库”。我也为它引用的库项目做了这个。这修复了我升级到SDK 22后未找到错误的类。
