Question

与回收站视图持有者中显示的Google地图（精简模式）相关的大量崩溃报告。

只有HockeyApp报告这些崩溃，而Firebase Crashlytics则不报告。
据报道，相对较少的用户崩溃发生了数百次，因此似乎影响了某些类型的用户。
在各种设备（华为，LG，三星等）上出现在一系列Android版本（7.0、8.0、8.1、9）上。
总是报告与地图有关的DeadSystemException，因此我排除了由于其他原因设备正在关闭的情况。
在没有安装Google Play服务且没有崩溃的情况下在模拟器上进行了测试；然后，地图视图会显示预期的错误消息MyApp won't run without Google Play services, which are not supported by your device.

根据设备的不同，堆栈跟踪看起来略有不同。

对于华为：

地图的实现方式如下：

视图架布局（简化）：

<com.google.android.gms.maps.MapView
    android:id="@+id/map"
    android:layout_width="@dimen/_100sdp"
    android:layout_height="@dimen/_100sdp"
    android:visibility="gone"
    map:liteMode="true"
    map:mapType="none" />

View Holder（简体）：

public class MyHolder extends RecyclerView.ViewHolder implements OnMapReadyCallback {

    private @NonNull MapView mapView;
    private @Nullable Location location;

    public MyHolder(@NonNull View itemView) {
        super(itemView);

        mapView = itemView.findViewById(R.id.map);
        mapView.onCreate(null);
        mapView.getMapAsync(this);

        LocalBroadcastManager.getInstance(App.getInstance().getApplicationContext()).registerReceiver(broadcastReceiver, new IntentFilter(MyFilter));
    }

    // Called when the view holder is recycled
    public void recycle() {

        mapView.setVisibility(View.GONE);
        releaseMap();
    }

    // Called when binding the view holder or by the broadcast receiver
    public void update(@NonNull Location location) {
        this.location = location;

        mapView.setVisibility(View.VISIBLE);
        setMapLocation();
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {

        MapsInitializer.initialize(App.getInstance().getApplicationContext());
        map = googleMap;
        map.getUiSettings().setMapToolbarEnabled(false);
        map.getUiSettings().setAllGesturesEnabled(false);

        setMapLocation();
    }

    private void setMapLocation() {

        if (map == null) {
            return;
        }

        if (location == null) {
            map.setMapType(GoogleMap.MAP_TYPE_NONE);
            return;
        }

        LatLng mapLocation = new LatLng(location.getLatitude(), location.getLongitude());
        map.addMarker(new MarkerOptions().position(mapLocation));
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(mapLocation, 14f));
        map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    }

    private void releaseMap() {

        if (map == null) {
            return;
        }

        map.clear();
        map.setMapType(GoogleMap.MAP_TYPE_NONE);
    }

    private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {

            update();
        }
    };
}

这可能是什么原因？

Answer 1

我也已经开始在我的App中看到这一点，但是决定，对此不能做太多事情。根据{{3}}的意思是：

核心Android系统已经死亡，正在运行重新开始。所有正在运行的应用程序将被立即杀死。

实际上，这实际上意味着您的应用经常在内存中，这可能意味着用户喜欢它。在开始与Android内存清理（即Application.onTrimMemory()或Activity.onTrimMemory()交互之后，使用我的应用程序，我开始获得这些代码，因为它们适合使应用程序（的核心）保留在内存中更长。

这表示，除非您考虑，否则应用程序本身会导致Android系统死亡，但是您可能必须在其他地方搜索。内存泄漏，本机组件等。

是什么原因导致android.gms.dynamite_mapsdynamite出现DeadSystemException？
