Android - Sending GPS Location to Emulator

Assuming you've got a mapview set up and running:

MapView mapView = (MapView) findViewById(R.id.mapview);
final MyLocationOverlay myLocation = new MyLocationOverlay(this, mapView);

mapView.getOverlays().add(myLocation);
myLocation.enableMyLocation();

myLocation.runOnFirstFix(new Runnable() {
    public void run() {
        GeoPoint pt = myLocation.getMyLocation();
    }
});

You'll need the following permission in your manifest:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

And to send mock coordinates to the emulator from Eclipse, Go to the "Window" menu, select "Show View" > "Other" > "Emulator control", and you can send coordinates from the emulator control pane that appears.

Android - Access SQLite Database File in Emulator

You have to be on the DDMS perspective on your Eclipse IDE

(Window > Open Perspective > Other > DDMS)

and the most important:

YOUR APPLICATION MUST BE RUNNING SO YOU CAN SEE THE HIERARCHY OF FOLDERS AND FILES.

Then in the File Explorer Tab you will follow the path :

data > data > your-package-name > databases > your-database-file.

Then select the file, click on the disket icon in the right corner of the screen to download the .db file. If you want to upload a database file to the emulator you can click on the phone icon(beside disket icon) and choose the file to upload.

If you want to see the content of the .db file, I advise you to use SQLite Database Browser, which you can download here.

PS: If you want to see the database from your real device, you must root your phone.

How to forward localhost IP-Address to an Android Emulator

Each emulator instance provides a control console the you can connect to, to issue commands that are specific to that instance. You can use the redir console command to set up redirections as needed for an emulator instance.

First, determine the console port number for the target emulator instance. For example, the console port number for the first emulator instance launched is 5554. Next, connect to the console of the target emulator instance, specifying its console port number, as follows:

telnet localhost 5554

Example:

Assume that your environment is
A is you development machine
B is your first emulator instance, running on A

Set up the server on B, listening to 10.0.2.15:<serverPort>
On B's console, set up a redirection from A:localhost:<localPort> to B:10.0.2.15:<serverPort>

* 10.0.2.15 is the default Ip Address of the Emulator
** For Windows: All Commands must be written in "Windows Command Prompt"

Android - How To Make 2 or More Emulator Communicate Each Other

Each emulator instance provides a control console the you can connect to, to issue commands that are specific to that instance. You can use the redir console command to set up redirections as needed for an emulator instance.

First, determine the console port number for the target emulator instance. For example, the console port number for the first emulator instance launched is 5554. Next, connect to the console of the target emulator instance, specifying its console port number, as follows:

telnet localhost 5554

Once connected, use the redir command to work with redirections. To add a redirection, use:.

redir add <protocol>:<host-port>:<guest-port>

where <protocol> is either tcp or udp, and <host-port> and <guest-port> sets the mapping between your own machine and the emulated system, respectively.

For example, the following command sets up a redirection that will handle all incoming TCP connections to your host (development) machine on 127.0.0.1:5000 and will pass them through to the emulated system's 10.0.2.15:6000.:

redir add tcp:5000:6000

Or UDP
redir add udp:5000:6000


Example:

Assume that your environment is

A is you development machine
B is your first emulator instance, running on A
C is your second emulator instance, running on A too
and you want to run a server on B, to which C will connect, here is how you could set it up:

Set up the server on B, listening to 10.0.2.15:<serverPort>
On B's console, set up a redirection from A:localhost:<localPort> to B:10.0.2.15:<serverPort>
On C, have the client connect to 10.0.2.2:<localPort>


** For Windows All commands must be written in a "Windows Command Prompt"

How To Deploy XAP File Directly To Your Emulator

If you ever want to install/ deploy XAP file to your emulator just run the following application;

"C:\Program Files\Microsoft SDKs\Windows Phone\v7.0\Tools\XAP Deployment\XapDeploy.exe"

*path can vary according to the installation path.

This is helpful for testing whether the XAP file you made has all the needed resources like: Images, DBFile etc.
