Running Android Develop on Win 7 64-bit

I just updated my OS to win 7 64-bit. I can use all 6 GB of RAM. But the Android Development really gave me trouble. The Eclipse 64-bit might be a good idea but it requires Java-64. Java-64 might conflict with other 32-bit application. In the end, I have to use Java-32 and Eclipse 32.

After Eclipse is installed, you need go to Help->Update Software. That will install the Android Plugin for Eclipse. Once the plugin is installed, you can install Android SDK and point the Android SDK directory in Eclipse.

Since there are many things to download in the Android SDK and I am tired of downloading, I decided to use the old Android SDK directory.

After the Android SDK is pointed to the right directory, you can start developing. Using virtual machine is no problem. If you want to use the real devices, you have to install ADB driver. The driver will recognize your device through USB cable. Common drivers are installed in the Androids SDK usb_driver directory.

For LG Ally, there is an LG driver you need to install. Once you have that installed, everything will be fine.

How to post rating

myRating = new RatingBar(this);  //Create a rating bar.
myRating_Label = new TextView(this);  //Create a label;
  
myRatingView = new LinearLayout(this);  //Create a LinearLayout
myRatingView.setOrientation( LinearLayout.VERTICAL );

myRatingView.addView(myRating_Label);  //Add the label to the View
myRatingView.addView(myRating);  //Add rating bar to the View
  
alert = new AlertDialog.Builder(this).create(); //Create a AlertDialog

alert.setView(myRatingView);  //Add the Rating View to the alert

  // Add a button to the Alert
alert.setButton("Submit", new DialogInterface.OnClickListener() {
   public void onClick(DialogInterface dialog, int whichButton) {
    String value = "Thanks for your rating " + String.valueOf(User_Rating);
    Toast.makeText(getApplicationContext(), value, Toast.LENGTH_SHORT).show();

   }
});

Create menu

When the Menu button is press on the phone, you can show up a menu to let user do something

public boolean onKeyDown(int keyCode, KeyEvent event){
    if(keyCode == KeyEvent.KEYCODE_MENU) {
         AlertDialog.Builder dialogBuilder = 
             new AlertDialog.Builder(this)
             .setMessage("Dialog Message")
             .setTitle("The Title");
         dialogBuilder.create().show();
         return true;
         }
     return super.onKeyDown(keyCode, event);
}

Fetch data from html

    public void Fetch_Data(){
     line = "";
        try {
      // Perform action on click
      //Log.w("Fetchhhhhhhhhhhhh","You are going to fetch tip data");
      String tempStr = ""; 
      // Initiate the url connection
      URL url = new URL(The_URL);
      HttpURLConnection conn = (HttpURLConnection) url.openConnection();
      // Get the response
      BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
      while ( (tempStr= rd.readLine()) != null) {
       line = line + tempStr;
       }
      rd = null;
      conn.disconnect();
      }
     catch (Exception e) {
      Log.w("===========",e);

     }
    }

How to use Spinner

private List Game_Mode_List
  for (int i=0;i < Game_Mode.length ;i++) {
   // Populate the Game_Mode List
   Game_Mode_List.add(Game_Mode[i]);
  }
   // Put the Game_Mode_List to an Addapter and set addapter tpye
  ArrayAdapter Game_Mode_Addapter = new ArrayAdapter(
    this, android.R.layout.simple_spinner_dropdown_item, Game_Mode_List);
  Game_Mode_Addapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item );
  
    // Create Spinner and attach the addapter to it.
  Spinner Game_Mode_Spinner = new Spinner(this);
  Game_Mode_Spinner.setAdapter(Game_Mode_Addapter);
    // The listener will listen the change. arg2 is the item selected
  Game_Mode_Spinner.setOnItemSelectedListener(
       new AdapterView.OnItemSelectedListener() {
     @Override
     public void onItemSelected(AdapterView arg0, View arg1, int arg2, long arg3) {
      myGameMode = String.valueOf(arg2);
     }
     @Override
     public void onNothingSelected(AdapterView arg0) {
      myGameMode = "1";
     }
       }
   );

Program Android on Mac

According to some websites, in order to develop android device on a Mac, all you need to do is to add the adb tool path to your .bash_profile. There is a script that do that for you. adb for Mac

In addition to that, it seems the cable also play an important role. The cable comes with MID does not work. Only the cable comes with the LG ally can work with Eclipse.

Send data to php

A php can read "POST" data. The following code can be used.

public void Fetch_Html() {
    try {

        String Data_username = URLEncoder.encode("username", "UTF-8") + "=" + URLEncoder.encode("Test username", "UTF-8");
        String Data_email = URLEncoder.encode("email", "UTF-8") + "=" + URLEncoder.encode("Test Email", "UTF-8");
        String Data_tip = URLEncoder.encode("tip", "UTF-8") + "=" + URLEncoder.encode("This tip", "UTF-8");

        String Quest_Data = Data_username + "&" + Data_email + "&" + Data_tip;

        The_URL = "http://ad-mountain.com/tipSubmit.php";

// Initiate the url connection
        URL url = new URL(The_URL);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setUseCaches(false);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Connection", "Keep-Alive");
        conn.setRequestProperty("Charset", "UTF-8");
        conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded"  );
        conn.setRequestProperty("Content-Length", "" + Integer.toString(Quest_Data.getBytes().length));
        conn.connect();

        DataOutputStream ds = new DataOutputStream(conn.getOutputStream());
        ds.writeBytes(Quest_Data);
        ds.flush();
        Log.w("=========", Quest_Data);

        conn.disconnect();

        ds.close();


    }
        catch (Exception e) {}
  }

Make Android connection

Update: Actually, both of the following code would work on my S7 and Ally. The headset I tried has only one profile implemented. That's the reason it can not be found by S7.

mmSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
mmSocket.connect();

The following code is suggested.

private static String address = "00:19:7F:1F:20:DF";
private BluetoothSocket btSocket = null;

mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);

Method m = null;
m = device.getClass().getMethod("createRfcommSocket", new Class[]{int.class});
btSocket = (BluetoothSocket)m.invoke(device, Integer.valueOf(1));
btSocket.connect();

Computer setup

The new computer client setup is not hard. Sever things I have noticed.

}

public void sleep(long delayMillis) {
this.removeMessages(0);
sendMessageDelayed(obtainMessage(0), delayMillis);
}
};

private void updateUI(){
int currentInt = Integer.parseInt((String) txtStatus.getText()) + 10;
if(currentInt <= 100){
mRedrawHandler.sleep(1000);
txtStatus.setText(String.valueOf(currentInt));
txtViewer.setText(String.valueOf(currentInt*100));
}
}

@Override
