該項目的構建和運行成功，但是當我啓動應用程序時崩潰，說不幸你的應用程序停止。添加谷歌地圖到我的Android應用程序
任何人都可以幫助我嗎？
這段代碼有什麼問題？
這裏是MainActivity.java
package app.elbalshy.mohamed.myapplication_map;
import android.app.Dialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GoogleApiAvailability;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {
GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
googleServicesAvilable();
Toast.makeText(this, "Perfect", Toast.LENGTH_LONG).show();
initMap();
}
private void initMap() {
SupportMapFragment mapFragment =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapFragment);
mapFragment.getMapAsync(this);
}
public boolean googleServicesAvilable()
{
GoogleApiAvailability api = GoogleApiAvailability.getInstance();
int isAvilable = api.isGooglePlayServicesAvailable(this);
if(isAvilable== ConnectionResult.SUCCESS)
{
Toast.makeText(this, "SUCCESSFULLY", Toast.LENGTH_LONG).show();
return true;
}
else if(api.isUserResolvableError(isAvilable))
{
Toast.makeText(this, "ResolvableError", Toast.LENGTH_LONG).show();
Dialog dialog = api.getErrorDialog(this, isAvilable,0);
dialog.show();
}
else
{
Toast.makeText(this, "Cant't connect to Play Services.", Toast.LENGTH_LONG).show();
}
return false;
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
}
}
AndroidManifest.xml中
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
