我的应用有问题。 一切都还可以，但是当我尝试将地图片段添加到我的活动中时，我的应用程序已停止。我认为一切都很好：我拥有自己的谷歌Api密钥，权限等。在我的代码中，我指出了我的代码中的新内容。
public class OpisMiejscaActivity extends FragmentActivity
{
Miejsce zMiejsce;
boolean mShowMap;
GoogleMap zMap;
private ImageView imgView;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.opis_miejsca_activity);
getActionBar().setDisplayHomeAsUpEnabled(true);
//this line is new
mShowMap = GooglePlayServiceUtility.isPlayServiceAvailable(this) && initMap();
Bundle b = getIntent().getExtras();
zMiejsce = b.getParcelable(".model.Miejsce");
display();
}
//this initMap is new
private boolean initMap()
{
// TODO Auto-generated method stub
if(zMap == null)
{
MapFragment mapFrag = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
zMap = mapFrag.getMap();
}
return (zMap != null);
}
private void display()
{
TextView tv = (TextView) findViewById(R.id.titleText);
tv.setText(zMiejsce.getTytul1());
NumberFormat nf = NumberFormat.getCurrencyInstance();
tv = (TextView) findViewById(R.id.priceText);
tv.setText(nf.format(zMiejsce.getKoszt()));
tv = (TextView) findViewById(R.id.descText);
tv.setText(zMiejsce.getOpis());
//this if is new
if (mShowMap)
{
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(zMiejsce.getLatLng(), 5);
zMap.moveCamera(update);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.opis_miejsca, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_goto_action :
break;
case android.R.id.home:
break;
}
return false;
}
}

答案 0 :(得分：0)
您没有将OpisMiejscaActivity声明为清单中的活动
答案 1 :(得分：0)
正如您收到的错误所述：
您必须在application元素中包含以下声明：
<meta-data
<android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
因此，请将此元数据标记添加到xml清单文件中：
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
答案 2 :(得分：0)
你的例外说：
ActivityNotFoundException：无法找到显式活动类{com.example.mysteriouspoland / com.example.mysteriouspoland.OpisMiejscaActivity};你有没有在AndroidManifest.xml中声明这个活动？
因此，您需要在清单文件的应用程序标记中提及您的活动，例如：
<activity android:name="com.example.mysteriouspoland.OpisMiejscaActivity" />
并将此元数据标记添加到xml清单文件中，如：
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
