मैंने अपने आवेदन में Google मानचित्र कार्यक्षमता को जोड़ा है, अब मैं आपसे पूछ रहा हूं, क्या कोई तरीका है, मैं इस मानचित्र को कैसे देख सकता हूं दृश्य रूटिंग कार्यक्षमता। मेरे पास मेरे जीपीएस (जैसे स्टार्ट) और मेरे गंतव्य के निर्देशांक से मेरे निर्देशांक होंगे। मैं मार्ग खींचना चाहता हूं, जिसे मुझे खत्म करने के लिए लेना चाहिए। क्या यह संभव है?एंड्रॉइड - Google मानचित्र रूटिंग
धन्यवाद
सबसे होनहार समाधान मैक्स Gontar द्वारा दिए गए देख Hmyzak ... यह मेरे लिए काम किया। J2ME/Android/BlackBerry - driving directions, route between two locations

इस मैं डेटाबेस में पहले रिकार्ड निर्देशांक करना क्या होता है, जबकि स्थान परिवर्तन करने के लिए
public void startRouteTracking(){
// Acquire a reference to the system Location Manager
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
locationListener = new LocationListener() {
LocationOpenHelper myLocationDb = new LocationOpenHelper(Main.this);
SQLiteDatabase locationDb = myLocationDb.getWritableDatabase();
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
@Override
public void onLocationChanged(Location location) {
//if last location is known and the current location is newer than last location
//if ((lastLocation != null) && (location.getTime() > lastLocation.getTime())){
if ((lastLocation != null)){
ContentValues values = new ContentValues();
values.put(COLUMN_LATITUDE, location.getLatitude());
values.put(COLUMN_LONGITUDE, location.getLongitude());
values.put(COLUMN_TIME, location.getTime());
values.put(COLUMN_SPEED, location.getSpeed());
values.put(COLUMN_DISTANCE_TO_LAST_LOC, location.distanceTo(lastLocation));
locationDb.insert(LOCATION_TABLE_NAME, null, values);
statusTextView.setText("provider " + location.getProvider() + location.getLatitude() + " " + location.getLongitude() + "speed:" + location.getSpeed() + "distance: " + location.distanceTo(lastLocation));
}
lastLocation = location;
}
};
// Register the listener with the Location Manager to receive location updates
// Update every 5 seconds or 5 meters, whichever comes first
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
}
दूसरा सुन, डेटाबेस से निर्देशांक को पुनः प्राप्त करने और डेटा पास है नक्शा खंड संवाद
