Android: How to build AOSP (Android Full Source)

·         make -j24 -k 2>&1 | tee android.log

o   -j

: Allow N jobs at once

: Use to raise compile speed

: For example, if the number of CPU is 4, as create process 4 by command -j4, build speed can raise.

o   -k

: --keep-going

: Keep going when some targets can’t made (Keep going run build although error occurred)

: If you want to check error when error occurred immediately, you don’t need to use this command.

o   2>&1

: n >&m

: n or m è 0,1,2 è 0: standard input (stdin) / 1: standard output (stdout) / 2: standard err (stderr)

: deliver the 2(stderr) to 1(stdout)

o   |

: run command additionally

o   tee

: Copy to file the object of stdin/stdout ( object of stdin/stdout : build logs in consol window )

: Can be check the build log in consol window directly and also can be save logs as file

Android: How to keep current state (Using SharedPreferences method)

1. Save Data
    SharedPreferences shprefs
                          = getSharedPreferences((String)"GroupSMSApp", MODE_PRIVATE);
    SharedPreferences.Editor preeditor = shprefs.edit();
    preeditor.putString((String)"s_prefix", mPrefix);

public interface

SharedPreferences

android.content.SharedPreferences

Class Overview

---

Interface for accessing and modifying preference data returned by getSharedPreferences(String, int). For any particular set of preferences, there is a single instance of this class that all clients share. Modifications to the preferences must go through an SharedPreferences.Editor object to ensure the preference values remain in a consistent state and control when they are committed to storage. Objects that are returned from the various get methods must be treated as immutable by the application.

Note: currently this class does not support use across multiple processes. This will be added later.

Developer Guides

For more information about using SharedPreferences, read the Data Storage developer guide.

Android: How to send SMS

Add Permission into Manifest

    <uses-permission android:name="android.permission.SEND_SMS" />
    <uses-permission android:name="android.permission.WRITE_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />



Add API into Source
private void sendSMS(String m_phoneNumber, final String m_smsMessage)
{      
    String SENT         = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";
     
    Log.d(TAG, "In sendSMS()");

    PendingIntent sentPI    
                             = PendingIntent.getBroadcast(this, 0, new Intent(SENT),      0);
    PendingIntent deliveredPI
                             = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0);
             
    Log.d(TAG, "sendTextMessage() : number = " + m_phoneNumber
                                                                     + ", Message = " + m_smsMessage);
     
    // Write SMS data into DB
    ContentValues values = new ContentValues();
    values.put("address",   m_phoneNumber.replace("-", ""));
    values.put("body",       m_smsMessage);
    values.put("protocol",  MESSAGE_TYPE_SENT);
    getContentResolver().insert(Uri.parse("content://sms/sent"), values);
     
    // Send Text Message
    SmsManager.getDefault().sendTextMessage(m_phoneNumber.replace("-", ""),

Android: Group SMS which is based on contact group

This post is just for introduce "Group SMS" application.

Sometimes, we need to send SMS to my customer, friends or anyone.

In this case, this application can help you to send SMS to people.

  

  

We can input prefix and postfix about each contact name and message body.

For example,

   Prefix               : Dear

   Contact Name  : Victor, Crum

   Postfix             : .

   Message Body : Thanks for your APP.

   Then 2 messages will be made automatically as below.

   - Dear Victor.

      Thanks for your APP.

   - Dear Crum.
      Thanks for your APP.

   Finally, this messages will be sent to each person.


You can download this APP for nothing as the below path.

Android: Saving SMS data into DB

We can send the SMS by using the below API.
    SmsManager.getDefault().sendTextMessage()

But it is not saved into the conversation list.
For this reason, we can't know what message is sent.

Now, I wanna let you know how to save it.

1. Add <uses-permission>

    <uses-permission android:name="android.permission.SEND_SMS" />
    <uses-permission android:name="android.permission.WRITE_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />


2. Add Code
    public class TestActivity extends Activity {

        public static final int MESSAGE_TYPE_ALL    = 0;
        public static final int MESSAGE_TYPE_INBOX  = 1;
        public static final int MESSAGE_TYPE_SENT   = 2;
        public static final int MESSAGE_TYPE_DRAFT  = 3;
        public static final int MESSAGE_TYPE_OUTBOX = 4;
        public static final int MESSAGE_TYPE_FAILED = 5; // for failed outgoing messages
        public static final int MESSAGE_TYPE_QUEUED = 6; // for messages to send later



       @Override
        protected void onCreate(Bundle savedInstanceState) {

             ContentValues values = new ContentValues();

             values.put("address",  m_phoneNumber.replace("-", ""));
             values.put("body",       m_smsMessage);
             values.put("protocol",  MESSAGE_TYPE_SENT);
             getContentResolver().insert(Uri.parse("content://sms/sent"), values);

    In this point, "content://sms/sent" is really really important.
    Please take a look at the below picture.
    The left side is MT SMS and right side is MO SMS.

    "content://sms/sent"   : Save as MO SMS
    "content://sms/inbox" : Save as MT SMS
