Question

我目前正在努力改进现有的Android应用程序，该应用程序可以映射区域中不同类型的树。

从Google Play商店下载应用程序时，地图工作正常。但是，当我在Android Studios中进行操作时，它只是显示灰色屏幕。

我从谷歌获得了一个API密钥并将其放在google_maps_api.xml

中

这就是我正在初始化地图的方式：

    if key == ['k']: 
        win.clearBuffer()
        win.flip()
        return win, None

    elif key == ['r']: 
        win.close()
        display.init()
        display.set_mode(resolution, FULLSCREEN |DOUBLEBUF,32)
        pylink.openGraphics()

        print 'This is a monocular calibration routine. Please select the appropriate eye.'

        # set calibration colors (target, background)
        pylink.setCalibrationColors((255, 255, 255), (0, 0, 0))
        # set calibration target size (diameter, hole)
        pylink.setTargetSize(int(0.25 * degToPix), int(0.05 * degToPix))
        # set calibration sounds
        pylink.setCalibrationSounds('', '', '')
        pylink.setDriftCorrectSounds('', 'off', 'off')

        # custom calibration routine: randomize and repeat first target must be turned off inside EYELINK
        #        5    1    6
        #          9   10
        #        3    0    4
        #          11   12
        #        7    2    8

        EYELINK.sendCommand('calibration_type = HV9')
        EYELINK.sendCommand('generate_default_targets = NO')      
        EYELINK.sendCommand('calibration_targets = %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d' % eyeCoordsR)    
        EYELINK.sendCommand('validation_targets = %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d' % eyeCoordsR)
        EYELINK.doTrackerSetup()
        pylink.closeGraphics()
        display.quit()

        win = ps.visual.Window(resolution, units = 'pix', fullscr = True, screen = 1, color = (0, 0, 0), colorSpace = 'rgb255', useFBO = False)
        return win, None

    elif key == ['l']: 
        win.close()
        display.init()
        display.set_mode(resolution, FULLSCREEN |DOUBLEBUF,32)
        pylink.openGraphics()

        print 'This is a monocular calibration routine. Please select the appropriate eye.'

        # set calibration colors (target, background)
        pylink.setCalibrationColors((255, 255, 255), (0, 0, 0))
        # set calibration target size (diameter, hole)
        pylink.setTargetSize(int(0.25 * degToPix), int(0.05 * degToPix))
        # set calibration sounds
        pylink.setCalibrationSounds('', '', '')
        pylink.setDriftCorrectSounds('', 'off', 'off')

        # custom calibration routine: randomize and repeat first target must be turned off inside EYELINK
        #        5    1    6
        #          9   10
        #        3    0    4
        #          11   12
        #        7    2    8

        EYELINK.sendCommand('calibration_type = HV9')
        EYELINK.sendCommand('generate_default_targets = NO')      
        EYELINK.sendCommand('calibration_targets = %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d' % eyeCoordsL)    
        EYELINK.sendCommand('validation_targets = %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d, %d' % eyeCoordsL)            
        EYELINK.doTrackerSetup()
        pylink.closeGraphics()
        display.quit()

        win = ps.visual.Window(resolution, units = 'pix', fullscr = True, screen = 1, color = (0, 0, 0), colorSpace = 'rgb255', useFBO = False)
        return win, None

    elif key == ['e']: 
        print '\t Exit? YES (Y) or NO (N)'
        key = ps.event.waitKeys(keyList = ['y', 'n']) 
        if key == ['y']: 
            return win, True
        elif key == ['n']:
            return win, False

这些是我在AndroidManifest中使用的权限：

if (savedInstanceState != null) {
        mMapFragment = (MapFragment) myFragmentManager.findFragmentByTag("map_tag");

        mMapFragment.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(GoogleMap googleMap) {
                mMap = googleMap;

                setUpMap();
            }
        });
        myFragment = (ControlClass) myFragmentManager.findFragmentByTag("control_tag");
        fragmentTransaction.commit();
        //mMap=mMapFragment.getMap();

    } else {

        mMapFragment = MapFragment.newInstance();
        fragmentTransaction.add(R.id.map, mMapFragment, "map_tag");

        useGPS = true;

        mMapFragment.setRetainInstance(true);
        myFragment = new ControlClass();
        fragmentTransaction.add(R.id.myfragment, myFragment, "control_tag");
        fragmentTransaction.commit();

        mMapFragment.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(GoogleMap googleMap) {
                mMap = googleMap;

                setUpMap();
                //handleNewLocation(lastKnownPosition);

            }
        });

    }

这是我对地图活动的布局：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

任何帮助将不胜感激！

事实证明，有两个版本的google_maps_api.xml，我的清单指的是调试版本，它仍然包含以前的api密钥。更改google_maps_api.xml调试版本中的密钥解决了问题。

谷歌地图在Play商店中运行，但在开发中不起作用
