getAllNetworkInfo

I check getAllNetworkInfo() API. There are many network in my android. I get all network.

NetworkInfo[] ni = cm.getAllNetworkInfo();

print network information.

Log.d("net", "getDetailedState = " + dt);
Log.d("net", "getExtraInfo = " + ni[i].getExtraInfo());
Log.d("net", "getReason = " + ni[i].getReason());

NetworkInfo.State st = ni[i].getState();

Log.d("net", "getState = " + st);
Log.d("net", "getSubtype = " + ni[i].getSubtype());
Log.d("net", "getSubtypeName = " + ni[i].getSubtypeName());
Log.d("net", "getType = " + ni[i].getType());
Log.d("net", "getTypeName = " + ni[i].getTypeName());
Log.d("net", "isAvailable = " + ni[i].isAvailable());
Log.d("net", "isConnected = " + ni[i].isConnected());
Log.d("net", "isConnectedOrConnecting  = " + ni[i].isConnectedOrConnecting ());
Log.d("net", "isFailover   = " + ni[i].isFailover  ());
Log.d("net", "isRoaming   = " + ni[i].isRoaming  ());

This is my phone result.

getDetailedState = DISCONNECTED

getReason = dataDisabled

getSubtype = 0
getSubtypeName = UNKNOWN

getTypeName = mobile

ConnectivityManager

I check ConnectivityManager Class.

I get Active network. If active network isn't, app makes exception.

ConnectivityManager cm = (ConnectivityManager)getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();

I print network information.

NetworkInfo.DetailedState dt = ni.getDetailedState();
Log.d("net", "getDetailedState = " + dt);
Log.d("net", "getExtraInfo = " + ni.getExtraInfo());
Log.d("net", "getReason = " + ni.getReason());
NetworkInfo.State st = ni.getState();
Log.d("net", "getState = " + st);
Log.d("net", "getSubtype = " + ni.getSubtype());
Log.d("net", "getSubtypeName = " + ni.getSubtypeName());
Log.d("net", "getType = " + ni.getType());
Log.d("net", "getTypeName = " + ni.getTypeName());
Log.d("net", "isAvailable = " + ni.isAvailable());
Log.d("net", "isConnected = " + ni.isConnected());
Log.d("net", "isConnectedOrConnecting  = " + ni.isConnectedOrConnecting ());
Log.d("net", "isFailover   = " + ni.isFailover  ());
Log.d("net", "isRoaming   = " + ni.isRoaming  ());

This result is 3g mobile active:

 getDetailedState = CONNECTED
 getExtraInfo = dm.jplat.net
 getReason = apnSwitched
 getState = CONNECTED
 getSubtype = 0
 getSubtypeName = UNKNOWN
 getType = 0
 getTypeName = mobile
 isAvailable = false
 isConnected = true
 isConnectedOrConnecting  = true
 isFailover   = false
 isRoaming   = false

This result is wifi active:

 getDetailedState = CONNECTED
 getExtraInfo = null
 getReason = null
 getState = CONNECTED
 getSubtype = 0
 getSubtypeName = 
 getType = 1
 getTypeName = WIFI
 isAvailable = true
 isConnected = true
 isConnectedOrConnecting  = true
 isFailover   = false
 isRoaming   = false

HttpClient

I use HttpClient Class. I would like to get yahoo's Web Page.
I create DefaultHttpClient Class and set url, create Http Get Message.

String url = "http://www.yahoo.co.jp";
HttpClient hc = new DefaultHttpClient();
HttpGet get = new HttpGet(url);

I do http Get execute. and receive http response.

HttpResponse res;
res = hc.execute(get);

If response is 200 OK, I get http content.

if (res.getStatusLine().getStatusCode() == 200) {
 //It is ok.
 InputStream input = res.getEntity().getContent();

I print http content by LogCat.

BufferedReader rBuffer = new BufferedReader(new InputStreamReader(input, "UTF-8"));
String readLine;

try {
 while((readLine = rBuffer.readLine()) != null) {
  Log.d("HttpClientActivity", readLine);

I could get yahoo's Web Page.

socket

I used Socket Class. I get my blog by Socket Class.

Create Socket.

String host ="playandworkandroid.blogspot.com"; 
sk = new Socket(host, 80);

I prepare for send data and receive data.

rBuffer = new BufferedReader(new InputStreamReader(sk.getInputStream()));
wBuffer = new BufferedWriter(new OutputStreamWriter(sk.getOutputStream()));

I make http Get messeage . and Send it!

wBuffer.write("GET / HTTP/1.1\n");
wBuffer.write("host : " + host + "\n");
wBuffer.write("\n");
wBuffer.flush();

If it receive data, print console.

while((readLine = rBuffer.readLine()) != null) {
 Log.d("HttpGetActivity", readLine);
}

I got my blog page.

ActivityInstrumentationTestCase2 GridView ClickItem

I think must be selected whether onClickItemListener API or onClickListener() API.
First, Test Target Activity...
Reference Basic GirdView Program to here.

Add OnItemClickListener() include GridView. It is selected position information.
OnItemClickListener Class.

mGridView.setOnItemClickListener(new OnItemClickListener() {

 @Override
 public void onItemClick(AdapterView arg0, View arg1, int position,
   long id) {
  Log.d("GridViewActivity", "onItemClick " + position + " " + id);
  
 }
 
});

Second, Tester. It is extends ActivityInstrumentationTestCase2. I call performItemClick with GridView and postion. must be UIThread

mActivity.runOnUiThread(new Runnable() {
 public void run() {
  
  Log.d("GridViewActivity", "performItemClick 3");
  gridview.performItemClick(gridview, 3, 0);
  
  
 }
});
mInstrumentation.waitForIdleSync();

Check Logcat.

performItemClick 3
onItemClick 3 0

It is OK.

ActivityInstrumentationTestCase2 GridView Select View

First, Test Target Activity...
Reference Basic GirdView Program to here.

Add OnClikcListener() include GridView. It is include position information. I create other
OnClickListener Class.

class OnClickListenerDetectPosition implements OnClickListener {
 private int mPosition = 0;
 public OnClickListenerDetectPosition(int position ) {
  mPosition = position;
 }
 @Override
 public void onClick(View v) {
  Log.d("GridViewActivity", "onClick = " + mPosition);
 }
 
}

register OnClickListner by it.

OnClickListener onclikclistener = new OnClickListenerDetectPosition(position);
imageView.setOnClickListener(onclikclistener);

Second, Tester. It is extends ActivityInstrumentationTestCase2. set position. must be UIThread

mActivity.runOnUiThread(new Runnable() {
 public void run() {
  Log.d("GridViewActivity", "setSelection 2");
  gridview.setSelection(2);
 }
});
mInstrumentation.waitForIdleSync();

get selected view and click view.

mActivity.runOnUiThread(new Runnable() {
 public void run() {
  
  Log.d("GridViewActivity", "getSelectedItemPosition = " + gridview.getSelectedItemPosition ());
  
  Log.d("GridViewActivity", "getSelectedView");
  ImageView imageview = (ImageView)gridview.getSelectedView();
  Log.d("GridViewActivity", "performClick");
  imageview.performClick();
 }
});

Check Logcat.

setSelection 2
getSelectedItemPosition = 2
onClick = 2

It is OK.
