Question

项目构建并成功运行但是当我启动应用程序时崩溃说不幸的是你的应用已停止。

任何人都可以帮助我吗？

此代码有什么问题？
这是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;


    }
}

的AndroidManifest.xml

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <meta-data android:name="com.google.maps.v2.API_KEY"
            android:value="AIzaSyBT6CZPIS5XY37b0r0D-6OQEPFb4ebWKtA"/>
        <meta-data android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version"/>

    </application>

</manifest>
