Recording Sound and Saving it in Android

Hey guys, in this blog we will see how to record sound in the android. The recorded sound will be saved in the "MediaRecorder" folder in your SD card. Run and test this project on the real device as it wont work on the emulator because emulators dont have mics to record.

Working with SoundPool Android

Hey Guys, Today we are going to see the usage of SoundPool in Android. So lets get started.

Download 

1) First of all create an Android Application Project.

2) Next go to "res/layout/activity_main.xml" and create a  button there.

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="play"
        android:id = "@+id/play"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" />

</RelativeLayout>

3) Now go to "src/your_package_name/MainActivity.java" and the code is here.

import android.app.Activity;
import android.media.SoundPool;
import android.media.SoundPool.OnLoadCompleteListener;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener{
    
    SoundPool sp;
    private Button btn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        btn = (Button) findViewById(R.id.play);
        btn.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch(v.getId()) {
        case R.id.play : playit();break;
        }
        
    }

    private void playit() {
        // TODO Auto-generated method stub

        sp = new SoundPool(1,AudioManager.STREAM_MUSIC,0);
        final int i = sp.load(this, R.raw.music, 0);
        sp.setOnLoadCompleteListener(new OnLoadCompleteListener() {

            @Override
            public void onLoadComplete(SoundPool arg0, int arg1, int arg2) {
                // TODO Auto-generated method stub
                sp.play(i, 1,1,0,0,1.0f);    
            }
            
        });
    }
}

Now we are done. Post your questions in the comment. I will be happy to answer those.

        android:id = "@+id/et" />
    
    <Button 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id = "@+id/send"
        android:text="send"/>

</LinearLayout>

3) Next go to "src/your_package_name/MainActivity.java" and here we are goin to retrieve the value written in the EditText and send the value to the "Second_Activity.java" on clicking the send button. The code looks like the following.

MainActivity.java

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;
import android.widget.EditText;

public class MainActivity extends Activity implements OnClickListener {
    EditText et;
    Button send;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        et = (EditText) findViewById(R.id.et);
        send = (Button) findViewById(R.id.send);

        send.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch (v.getId()) {
        case R.id.send:
            Intent i = new Intent(this, Second_Activity.class);
            i.putExtra("value", et.getText().toString());
            startActivity(i);
            break;
        }
    }

}

4) Now go to "res/layout" and create an Android Xml file there, for our case lets name it "show.xml" .

show.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id = "@+id/tv"
        android:text="Demo text"
        android:textColor="#000000" />
    

</LinearLayout>

5) Next go to "src/your_package_name/Second_Activity.java" and here we are going to retrieve the value send in by MainActivity.java and set the same value  in the TextView.

Second_Activity.java

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;

public class Second_Activity extends Activity {
    TextView tv;
    String word;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.show);
        try{
        word = getIntent().getExtras().getString("value");
        Toast.makeText(this, word, Toast.LENGTH_SHORT).show();
        }catch(Exception e) {
            Toast.makeText(this, "Exception raised", Toast.LENGTH_SHORT).show();
            
        }
        tv = (TextView) findViewById(R.id.tv);
        tv.setText(word);
    
    }

}

Note - Dont forget to declare the activity in AndroidManifest.xml

<activity android:name="com.example.passing_value.Second_Activity" /> 

Now we are done. Post your questions in the comment. I will be happy to answer those.

Drawing Graph in Android

Hello guys, whats up?? Today in this blog we are going to see how to draw graphs in Android. For this purpose we are going to use a library called as "achartengine" . So , lets get started.

Download 

1) First of all  create an Android Application Project.

2) Next go to "res/alyout/activity_main.xml" and create a LinearLayout there.

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/label"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

</LinearLayout>

3) Now go to http://www.achartengine.org/content/download.html and download "achartengine" library from there.

4) Right click on the project file in eclipse and go to properties->Java Bild Path-> Libraries-> Export External Jar files and select the downloaded "achartengine" library from there.

5) Now go to "src/your_package_name/MainActivity.java" and paste the following code there.

Develop Multilingual Android Application (Hindi)

Hello Guys , how are you today? Hope you will be fine.

Have you ever wondered how to write in Hindi or any other language in Android. In this tutorial we are going to see how to develop multilingual android application.

Download 

1) First of all, create an Android Application Project.

2) Next go to "res/layout/activity_main.xml" and create a TextView there. The code looks like

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id = "@+id/text" />

</RelativeLayout>

3) Now you need to download the font file of the language you wish to use. For our case its hindi, so i downloaded the "Mangal.ttf" file. You can google for your respective font file.

4) After downloading the font file save it in "assets/font/font_file.ttf" .

5) Next go to "src/your_package_name/MainActivity.java" and paste the below code.

import android.app.Activity;
import android.graphics.Typeface;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends Activity {
    TextView text;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
        text = (TextView) findViewById(R.id.text);
        Typeface tf = Typeface.createFromAsset(getAssets(), "font/Mangal.ttf");              
        //TextView tv = (TextView) findViewById(R.id.yourtextview);
        text.setTypeface(tf);
        text.setText("यह एक अच्छा एप्लीकेशन है | इ  लव इट |");
    }

}

Note - You can download and use google input tools for converting english to your respective languages. In our case it was Hindi so i used hindi.

Now we are done. Post your questions in the comment. I will be happy to answer those.

Building SideBar or Navigation Drawer in Android

Hello Guys, How are you today? Hope you all be fine..

Today we are going to see how to create sidebar or Navigation Drawer in Android.

Download 

1)  Go to "res/layout/activity_main.xml" and create Navigation drawer there. The code looks like

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">



<FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />



<ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="#111"/>
</android.support.v4.widget.DrawerLayout>

2) Create two more Android xml files in the "res/layout" folder . For our case lets name it "drawer_list_item.xml"  and "fragment_planet.xml"  .

drawer_list_item.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:textColor="#fff"
    android:background="?android:attr/activatedBackgroundIndicator"
    android:minHeight="?android:attr/listPreferredItemHeightSmall"/>

fragment_planet.xml

<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/image"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000"
    android:gravity="center"
    android:padding="32dp" />

3) In the "res/values/strings.xml" write the following code.

<resources>
    <string name="app_name">Navigation Drawer Example</string>
    <string-array name="planets_array">
        <item>Mercury</item>
        <item>Venus</item>
        <item>Earth</item>
        <item>Mars</item>
        <item>Jupiter</item>
        <item>Saturn</item>
        <item>Uranus</item>
        <item>Neptune</item>
    </string-array>
    <string name="drawer_open">Open navigation drawer</string>
    <string name="drawer_close">Close navigation drawer</string>
    <string name="action_websearch">Web search</string>
    <string name="app_not_available">Sorry, there\'s no web browser available</string>
</resources>

4) Next go to "res/menu/main.xml" .

main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/action_websearch"
          android:icon="@drawable/action_search"
          android:title="@string/action_websearch"
          android:showAsAction="ifRoom|withText" />
</menu>

5) Next go to "src/your_package_name/MainActivity.java" and paste the following code.

import java.util.Locale;

import android.app.Activity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.SearchManager;

Displaying Information In Dialog in Android

Hello guys, How are you today? I hope you all be in the best of your life.

Today, we are going to see how to show the information in dialog in Android. So , lets get started.

Download 

1) First of all, create an Android Application Project.

2) Next go to "res/layout/activity_main.xml" and create a button for which we are going to implement OnClickListener. The code looks like

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click Me"
        android:id="@+id/click" />

</RelativeLayout>

3) Next make an Android xml file in the "res/layout/" folder and create a TextView in there. For our case the name is "show.xml" .

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    
    <TextView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="You are awesome"
        android:textColor="#ffffff"/>
    

</LinearLayout>

4) Next go to "src/your_package_name/MainActivity.java" and implement OnClickListener for the click button. The code looks like

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener {
    Button click;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        click = (Button) findViewById(R.id.click);
        click.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch(v.getId()) {
        case R.id.click : Intent i = new Intent(this, Show.class);
        startActivity(i);
        break;
        }
    }

}

5) Now, we have to create a class "Show.java" in the "src/your_package_name" . In Show.java we are going to display the show.xml.

import android.app.Activity;
import android.os.Bundle;

public class Show extends Activity{
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.show);
        
    
    }

}

6) Now open AndroidManifest,xml and create an Show Activity with the dialog theme.

For our case its like

<activity android:theme="@android:style/Theme.Dialog" android:name="com.example.dialog_blog.Show" />

Now we are done. Post your questions in the comment. I will be happy to answer those.

Playing Video In Android

Hello Guys , How are you?? Its Super Sunday, hope you guys enjoying your weekend.

Today we will see how to Play Videos in Android. So lets get started.

Download 

1) First of all create an Android Application Project.

2) Go to "res/layout/activity_main.xml" and create a VideoView. The code looks like

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <VideoView  
        android:id="@+id/videoView1"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignParentLeft="true"  
        android:layout_centerVertical="true" />  

</RelativeLayout>

3) Next go to "src/your_package_name/MainActivity.java" and create set the MediaController for VideoView.

import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.widget.MediaController;
import android.widget.VideoView;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        VideoView videoView = (VideoView) findViewById(R.id.videoView1);

        // Creating MediaController
        MediaController mediaController = new MediaController(this);
        mediaController.setAnchorView(videoView);

        // specify the location of media file
        Uri uri = Uri.parse("android.resource://com.example.videoplayer_blog/"
                + R.raw.video1);

        // Setting MediaController and URI, then starting the videoView
        videoView.setMediaController(mediaController);
        videoView.setVideoURI(uri);
        videoView.requestFocus();
        videoView.start();
    }

}

Now we are done. Post your questions in the comment. I will be happy to answer those.
