map - Android AsyncTask error while adding items to GoogleMap -
i want load coordinates file , add shapes map in async task. getting error, , don't know why. here code:
private class shploading extends asynctask<googlemap, void, string> { progressdialog dialog; @override protected string doinbackground(googlemap... params) { shpreader shpread = new shpreader(); googlemap map = params[0]; try { shpread.reading(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (invalidshapefileexception e) { // todo auto-generated catch block e.printstacktrace(); } for(latlng : shpread.points()) map.addmarker(new markeroptions() .position(a) .draggable(false)); int = 0; for(list<latlng> a: shpread.lines()){ map.addpolyline(new polylineoptions() .addall(a) .width(3) .color(color.red)); } for(list<latlng> a: shpread.polygons()){ map.addpolygon(new polygonoptions() .addall(a) .strokewidth(3) .strokecolor(color.red) .fillcolor(0x3f00ff00)); } return "done"; } @override protected void onpreexecute() { dialog = new progressdialog(measuring.this); dialog.setmessage("kraunama..."); dialog.setindeterminate(true); dialog.setcancelable(false); dialog.show(); } @override protected void onprogressupdate(void... values) { } @override protected void onpostexecute(string result) { dialog.dismiss(); } } and how execute code:
shploading load = new shploading(); load.execute(mmap); mmap googlemap variable. if add doinbackground code onpostexecute method , change variable map global mmap eveything working, want task in background , show loading dialog @ same time.
here logcat:

add them map? maybe there better way this?
sorry can not change ui component background thread must write map operation in uithread.
your solution within existing code :
private handler mhandler = new handler(); private class shploading extends asynctask<googlemap, void, string> { progressdialog dialog; @override protected string doinbackground(googlemap... params) { shpreader shpread = new shpreader(); googlemap map = params[0]; try { shpread.reading(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (invalidshapefileexception e) { // todo auto-generated catch block e.printstacktrace(); } mhandler.post(new runnable() { public void run() { for(latlng : shpread.points()) map.addmarker(new markeroptions() .position(a) .draggable(false)); int = 0; for(list<latlng> a: shpread.lines()){ map.addpolyline(new polylineoptions() .addall(a) .width(3) .color(color.red)); } for(list<latlng> a: shpread.polygons()){ map.addpolygon(new polygonoptions() .addall(a) .strokewidth(3) .strokecolor(color.red) .fillcolor(0x3f00ff00)); } } }); return "done"; } @override protected void onpreexecute() { dialog = new progressdialog(measuring.this); dialog.setmessage("kraunama..."); dialog.setindeterminate(true); dialog.setcancelable(false); dialog.show(); } @override protected void onprogressupdate(void... values) { } @override protected void onpostexecute(string result) { dialog.dismiss(); } }
