我在Android 5上遇到了一个问题。x版本。它在Android 4.x中运行良好。
它崩溃的视图在ScrollView中包含一个GoogleMap。如果我不初始化映射，一切都可以正常工作。如果我初始化，有时应用程序崩溃或冻结，我得到以下错误(相同的错误从曲棍球几个设备，Android 5.0 - Android 5.1.1):

地图的初始化应该不是问题，但如果我不调用"在地图上绘制路线"函数，问题也不会发生。序列如下
- 启动活动并初始化地图
- 在地图上放置自定义标记
- 获取从用户位置到出口的路由//<——CRASH
缩放地图显示用户位置路线和出口
private void initializeMap() { if (googleMap == null) { scrollableMapFragment = ((ScrollableMapFragment) getSupportFragmentManager() .findFragmentById(R.id.retailer_detail_map)); googleMap = scrollableMapFragment.getMap(); // check if map is created successfully or not if (googleMap == null) { //show error } else { scrollableMapFragment .setListener(new ScrollableMapFragment.OnTouchListener() { @Override public void onTouch() { parallaxScrollView .requestDisallowInterceptTouchEvent(true); } }); googleMap.getUiSettings().setMyLocationButtonEnabled(false); googleMap.setLocationSource(this); //This is required for balancing power and (low) battery usage!!! googleMap.setMyLocationEnabled(true); googleMap.getUiSettings().setZoomControlsEnabled(false); googleMap.getUiSettings().setZoomGesturesEnabled(true); googleMap.getUiSettings().setCompassEnabled(true); googleMap.getUiSettings().setRotateGesturesEnabled(false); googleMap.getUiSettings().setTiltGesturesEnabled(false); googleMap.getUiSettings().setScrollGesturesEnabled(true); googleMap.getUiSettings().setMapToolbarEnabled(false); placeOneMapMarker(customType); } } } private void placeOneMapMarker(CustomType marker) { LatLng latLng = null; GeoCoordinate geoCoordinate; MarkerOptions marker = null; geoCoordinate = marker.getGeoCoordinate(); latLng = new LatLng(geoCoordinate.getLatitude(), geoCoordinate.getLongitude()); marker = new MarkerOptions().position(latLng); // some more custom configurations... BitmapDescriptor icon = null; icon = iconManager.getShrinkedMapMarker(nRKER); marker.icon(icon); // adding marker googleMap.addMarker(marker); //CRASH!!!! if we uncomment this, everything works as expected showRoute(); } private void showRoute(){ new Thread(new Runnable() { @Override public void run() { try { routeFromPosition = new LatLng(locationDao.getCurrentLocation().getLatitude(), locationDao.getCurrentLocation().getLongitude()); routeToPosition = new LatLng(outlet.getAddress().getGeoCoordinate().getLatitude(), outlet.getAddress().getGeoCoordinate().getLongitude()); GoogleMapRoute googleMapRoute = new GoogleMapRoute(); Document doc = googleMapRoute.getDocument(routeFromPosition, routeToPosition, GoogleMapRoute.MODE_DRIVING); directionPoint = googleMapRoute.getDirection(doc); runOnUiThread(new Runnable() { @Override public void run() { if (directionPoint != null && directionPoint.size() > 0) { showRoute(); } else { zoomToOutletPosition(); } } }); } catch (Exception e) { //handle error } } }).start();}
这里有一些日志，看起来像内存泄漏?

我们刚刚在android StrictMode的帮助下解决了这个问题
将以下内容添加到您的Activity onCreate()中，可以提供有关崩溃和策略违规的更详细信息。其中一个违规是我们崩溃的关键，但这与我发布的代码无关(问题作为副作用发生)
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork() // or .detectAll() for all detectable problems
.penaltyLog()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
.detectLeakedClosableObjects()
.penaltyLog()
.penaltyDeath()
.build());
//...
}
