I am thinking of making widget for Android that can display Google Maps.
Though i have made two classes one inheriting with MapActivity and the other with AppWidgetProvider but i am not sure how to use them. Could any one help it out?
package com.leaning.widget;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.widget.RemoteViews;
public class MapWidgo extends AppWidgetProvider {
MapGoogle obj = new MapGoogle();
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
// TODO Auto-generated method stub
super.onUpdate(context, appWidgetManager, appWidgetIds);
for(int i=0;i<appWidgetIds.length;i++)
{
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://maps.google.com"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews remote = new RemoteViews(context.getPackageName(), R.layout.main);
remote.setOnClickPendingIntent(R.id.webView1, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, remote);
}
}
}
now below is my MapGoogle Class
package com.leaning.widget;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
public class MapGoogle extends MapActivity {
#Override
protected void onCreate(Bundle icicle) {
// TODO Auto-generated method stub
super.onCreate(icicle);
MapView mapview = (MapView) findViewById(R.id.mySecretMap);
mapview.setBuiltInZoomControls(true);
final MapController controller = mapview.getController();
LocationManager manager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener listener = new LocationListener() {
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
controller.setCenter(new GeoPoint((int)location.getLongitude(),(int)location.getLatitude()));
}
};
manager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,0, listener);
}
#Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
and the last one is my manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.leaning.widget"

I want a quick solution!
maybe you can have a web service which reads a google map url and convert it to an image.
The,n what you need is simply a widget able to show an image from a web URL (there are many on Play)

I am creating an android app that consists of android push notifications.Here i need the push notifications that will run even when the app was closed. I had achieved it by calling the notification in a service. But here when i was running the code in the android >5.x devices my code was running perfectly even when app was closed notification was coming for every 5 sec but when i was running app on devices <5.x notifications was displaying only when the app was opened or when it was minimised not receiving any notifications when app was closed can any one help me what my mistake is and this is my code

Samsung phones have this problem. There is hack to this. You need to kick the locationmanager on the butt to get the latest location from the maps cache.
God.locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
new LocationListener() {
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
#Override
public void onLocationChanged(final Location location) {
}
});
currentLocation = God.locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
Call getLastKnownLocation after kicking the requestLocationUpdates with 0's.
It happens with emulators, try rebooting the emulator.
Or, close both eclipse and emulator and start both again
I have created a very basic program to track GPS coordinates. The program has a button that turns a service on and off. The service simple installs a LocationListener. On each onLocationChanged the location coordinates are dumped on sd card.
The application works fine. But when I push the sleep button, the application logs data for sometime and then causes Google Nexus One to reboot.
Below I am posting the MINIMUM code that is required to reproduce this bug. I have striped extra code to avoid confusion.

Please see if I am missing out something.
I want to pop up the alert dialog on location change through service. Here i have attached my manifest , Service and broadcastReciever codes.
In the console it is giving that .apk has been installed.
But i'm not getting any toast or alertdialog.

create an Activity and and register receiver in this activity and start service from this activity and use alert dialog in activity class

still have any doubts for Receiver,Service and GPS classes let me know!!
or even your can check Start Service from Broadcast Receiver and Get Current Location links for details. hope it helps!!
I'm trying to create a program for android that constantly (every minute) gets the gps location and then sends it to my server at home (so that i always know where my phone is).
I created a gui with a start-button which starts the service:
start.setOnClickListener(new View.OnClickListener() {
synchronized public void onClick(View v) {
startService(new Intent(GpsTest2.this, GTService.class));
}
});
Then my service is declared like this:
public class GTService extends Service implements LocationListener {
}
This GTService has a method for retrieving the data:
public void onLocationChanged(Location location) {
}
#Override
public void onCreate() {
super.onCreate();
LocationManager locMgr = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, interval * 1000, minDist, this);
}
In AndroidManifest.xml I have:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<service android:name=".GTService">
</service>
This doesn't seem to work: no data is logged.
What am I doing wrong here?
Your code seems to be working fine except this,
You are using LocationManager.NETWORK_PROVIDER
locMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, interval * 1000, minDist, this);
Where as it should be LocationManager.GPS_PROVIDER
locMgr.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2 * 1000, 10, locationListener);
Hope this will surely do for you. Thanks.
The location from Network provider is not accurate. PLease use GPS instead. If you really want to user Network only then I would recomond to set minDistance param as 0
The following should work fine,
Manifest :
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<uses-permission android:name="android.permission.LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.smartconcept.locationmonitor.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".GTService" />
</application>
GTService :
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
import android.widget.Toast;
public class GTService extends Service implements LocationListener {
LocationManager locMgr;
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onCreate(){
super.onCreate();
locMgr = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1 * 1000, 0, this);
}
#Override
public void onDestroy(){
super.onDestroy();
locMgr.removeUpdates(this);
}
#Override
public void onLocationChanged(Location loc) {
Toast.makeText(getBaseContext(), String.valueOf(loc.getLatitude()) + "\n" + String.valueOf(loc.getLongitude()), Toast.LENGTH_SHORT).show();
}
#Override
public void onProviderDisabled(String arg0) {
// TODO Auto-generated method stub
}
#Override
public void onProviderEnabled(String arg0) {
// TODO Auto-generated method stub
}
#Override
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
// TODO Auto-generated method stub
}
}
MainActivity:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btnStart = (Button)findViewById(R.id.btnStart);
btnStart.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
startService(new Intent(MainActivity.this,GTService.class));
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
Hope this helps.
