Question

我正在用MapActivity扩展我的活动，以动态实现MapView，其中包含显示mapView的片段。

public abstract class BaseHomeActivity extends MapActivity

我在如下片段中实现了MapView

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    rootView = (ViewGroup) inflater.inflate(R.layout.acs_widget_mymap, null);
    linearLayout = (LinearLayout) rootView.findViewById(R.id.mymap_widget_LinearLayout02);      
    if(AppStateObjects.getMapview() == null){       
        mapView = new CustomMapView(getActivity(), MAP_API_KEY);
    }else{
        mapView = AppStateObjects.getMapview();
    }

    this.inflater = inflater;
    mapView.setClickable(true);
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,
            LinearLayout.LayoutParams.FILL_PARENT);     
    mapLayout.addView(linearLayout, layoutParams);      
    mapOverlays = linearLayout.getOverlays();
    iconworker = this.getResources().getDrawable(R.drawable.pointer_worker);
    iconequipment = getResources().getDrawable(R.drawable.pointer_equipment);
    initBroadCastReceiver();
    return rootView;
}

下面是CustomMapView类

public class CustomMapView extends MapView
{
    // import com.google.android.maps.MapView;
    Context context;
    private Bitmap windowFrame;

    public CustomMapView(Context context, String apiKey)
    {
        super(context, apiKey);
        this.context = context;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev)
    {
        int action = ev.getAction();
        switch (action)
        {
            case MotionEvent.ACTION_DOWN:
                this.getParent().requestDisallowInterceptTouchEvent(true);
                break;

            case MotionEvent.ACTION_UP:
                this.getParent().requestDisallowInterceptTouchEvent(false);
                break;
        }
        super.onTouchEvent(ev);
        return true;
    }

    @Override
    protected void dispatchDraw(Canvas canvas)
    {
        super.dispatchDraw(canvas); 
        if (windowFrame == null)
        {
            createWindowFrame(); 
        }

        canvas.drawBitmap(windowFrame, 0, 0, null);
    }

    protected void createWindowFrame()
    {
        windowFrame = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888); 
        Canvas osCanvas = new Canvas(windowFrame); 
        RectF outerRectangle = new RectF(0, 0, getWidth(), getHeight());
        RectF innerRectangle = new RectF(0, 0, getWidth(), getHeight());
        float cornerRadius = getWidth() / 50f; 

        Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); 
        paint.setColor(Color.rgb(18, 42, 71)); 
        osCanvas.drawRect(outerRectangle, paint);
        paint.setColor(Color.RED); 
        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_OUT));
        osCanvas.drawRoundRect(innerRectangle, cornerRadius, cornerRadius, paint);
    }

    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b)
    {
        super.onLayout(changed, l, t, r, b);
        windowFrame = null; 
    }
}

当我在棉花糖设备（不是模拟器）上运行该应用程序时，一旦尝试加载BaseHomeActivity（扩展了MapActivity），该应用程序就会崩溃。

以下是崩溃：

问题：

在上面的本机崩溃中观察com.google.android.maps.jar。由于我使用的是“ Google Maps Android v1 API”，因此当我将应用程序从eclipse移植到Android Studio时（25及以上版本没有可用的Google API），我不得不使用API 26来实现JobIntentService等功能。 / p>

存在与MapActivity相关的编译错误，我通过将maps.jar添加到libs文件夹并添加为依赖项来解决。

如果我删除MapActivity并将BaseHomeActivity扩展到AppCompatActivity并注释掉我的地图代码，则该应用程序在棉花糖设备中运行良好。

在棉花糖中如何使用“ Google Maps Android v1 API”（使用Google Maps Android V2 API有一些限制）的任何想法，因为它可以在除Marshmallow之外的其他所有OS版本上使用。

先谢谢了。

仅在MarshMallow（6.0和6.0.1）上使用MapActivity for MapView会使应用程序崩溃
