java.lang.OutOfMemoryError:位图大小超出虚拟机预算,即使我不使用任何图像

我的应用程序遇到了以前从未遇到过的问题。我使用这个应用程序已经有一段时间了,并且运行了数千次,但我从未遇到过此错误。

我有一个服务器,它接收一些 GPS 数据,这些数据也写入数据库和单例类中。 在我的一个类中,我使用异步任务线程来从单例类中读取到达的新 GPS 数据并在地图上显示这些点。

现在突然我在这样的行中遇到错误:

mc.animateTo(p1);

where mc=mapView.getController();

这就是我的代码的样子:

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

             mapView = (MapView) findViewById(R.id.mapview1);

    mapView.setBuiltInZoomControls(true);

    mc = mapView.getController();

    mc.setZoom(17);

    mapView.setSatellite(true);

    mapView.setStreetView(true);

    mapView.invalidate();
}


public class InitTask extends AsyncTask<Void, GeoPoint, Void> {

    GeoPoint p;

    protected Void doInBackground(Void... voids) {

        try {

            while (true) {


                if(number.equals("Car1"))
                {
                longitude = ServerManager.getInstance().getLastLongitude1();
                latitude = ServerManager.getInstance().getLastLatitude1();
                speed = ServerManager.getInstance().getLastSpeed1();
                loc1 = ServerManager.getInstance().getLastLocation1();
                speed = ServerManager.getInstance().getLastSpeed1();
                }



                runOnUiThread(new Runnable() {
                    public void run() {
                        speed_1.setText(Integer.toString(speed));
                        location.setText(loc1);

                    }
                });


                p = new GeoPoint(latitude, longitude);

                publishProgress(p);

                Thread.sleep(1500);
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    protected void onProgressUpdate(GeoPoint... progress1) {

        theRouteDraw(progress1[0]);
    }

这就是 RouteDraw() 的样子:

public void theRouteDraw(GeoPoint p1) {

    mc.animateTo(p1);

    mc.setZoom(17);

    mapView.setSatellite(true);

    mapView.invalidate();
}

ServerManager 是我的单例类...我从那里读取新数据并使用publishProgress();以及 theRouteDraw() 方法在地图上显示这些点。

我没有在地图上使用任何叠加层或特殊图像。

我在这一行的方法中遇到错误

public void theRouteDraw(GeoPoint p1) {

    public void theRouteDraw(GeoPoint p1) {

    mc.animateTo(p1);

    mc.setZoom(17);

    mapView.setSatellite(true);

    mapView.invalidate();
}

:mc.animateTo(p1);

这是我的日志猫:

I'm having a problem in my app that I never met before.I've been having this app for a while and runned it thousands of time, but I never got this error.

I have a server that receives some GPS data that are written also in a DB and a singleton class.
In one of my classes I use an Async Task thread in order to read from the singleton class the new GPS data that arrived and display those points on the map.

And now suddenly I get error at a line like this:

mc.animateTo(p1);

where mc=mapView.getController();

This is how my code looks like:

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

             mapView = (MapView) findViewById(R.id.mapview1);

    mapView.setBuiltInZoomControls(true);

    mc = mapView.getController();

    mc.setZoom(17);

    mapView.setSatellite(true);

    mapView.setStreetView(true);

    mapView.invalidate();
}


public class InitTask extends AsyncTask<Void, GeoPoint, Void> {

    GeoPoint p;

    protected Void doInBackground(Void... voids) {

        try {

            while (true) {


                if(number.equals("Car1"))
                {
                longitude = ServerManager.getInstance().getLastLongitude1();
                latitude = ServerManager.getInstance().getLastLatitude1();
                speed = ServerManager.getInstance().getLastSpeed1();
                loc1 = ServerManager.getInstance().getLastLocation1();
                speed = ServerManager.getInstance().getLastSpeed1();
                }



                runOnUiThread(new Runnable() {
                    public void run() {
                        speed_1.setText(Integer.toString(speed));
                        location.setText(loc1);

                    }
                });


                p = new GeoPoint(latitude, longitude);

                publishProgress(p);

                Thread.sleep(1500);
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    protected void onProgressUpdate(GeoPoint... progress1) {

        theRouteDraw(progress1[0]);
    }

This is how theRouteDraw() looks like:

public void theRouteDraw(GeoPoint p1) {

    mc.animateTo(p1);

    mc.setZoom(17);

    mapView.setSatellite(true);

    mapView.invalidate();
}

ServerManager is my singleton class...I read new data from there and use publishProgress(); and the method theRouteDraw() to display those points on the map.

I'm not using any overlay or special image on my map.

I get error in this method

public void theRouteDraw(GeoPoint p1) {

    public void theRouteDraw(GeoPoint p1) {

    mc.animateTo(p1);

    mc.setZoom(17);

    mapView.setSatellite(true);

    mapView.invalidate();
}

at this line: mc.animateTo(p1);

This is my logcat:

谷歌地图图像图块是位图,谷歌地图也缓存一些图像,因此会分配位图。我面临着类似的问题。

在这种情况下,删除:

mc.animateTo(p1);

可能会解决它,这似乎会引发错误,并且这可能涉及加载相当多的图像是有道理的。您可能在某个地方存在内存泄漏,可能是对地图视图的引用,这是问题的根源。

Google maps image tiles are bitmaps and google maps does cache some images as well, so there are bitmaps being allocated. I'm facing similar problems.

In this case removing:

mc.animateTo(p1);

Will probably solve it, this seems to be throwing the error and it makes sense that this might involve the loading of quite a few images. You might have a memory leak somewhere, probably a reference to your mapview, which is the root of the problem.
