App crashed on launch | Android Studio App crashed on launch | App crashed on launch- Android 4.4

Hello friends,

Today I found the strange issue while making an signed/released Apk.

My app getting crashed when app launched on Android 4.4, 4.2 and other devices
and Its working fine with Debug build. After spending lots of time I found that the
issue is with Android studio 2.0 or higher.

The reason of crash is in Android studio 2.0 and higher Google added a new feature
of Instant Run which makes your development/emulation faster.The Instant run is
enabled in latest android studio. We need to make it disable while making a signed
release build.

Steps to Disable:
1. Open the Settings or Preferences dialog: On Windows or Linux, select File > Settings
    from the main menu. On Mac OSX, select Android Studio > Preferences from
    the main menu.
2. Navigate to Build, Execution, Deployment > Instant Run.
3  Unchecked the box next to Enable Instant Run to hoot swap code/resource
    changes on display. 



What is Instant Run??
Instant Run: This feature is supposed to dramatically improve your workflow by letting you quickly see changes running on your device or emulator. It lets you see your changes running “in a near instant,” which means you can continuously code and run your app, hopefully accelerating your edit, build, run cycles. When you click on the Instant Run button, it will analyze the changes you have made and determine how it can deploy your new code in the fastest way. Instant Run works with any Android Device or emulator running API 14 (Ice Cream Sandwich) or higher.


Hope this will help someone.
Enjoy Coding.... :)

Unity Pluging : Read all incoming sms | Unity Read SMS Plugin


Hello Friends,
              I read a lot that people facing problem in register and un-register the incoming
sms broadcast from Unity. Also reading incoming sms in Unity app .

     

              So, today I am going to share my first blog on Unity. This post helps you
to read all android incoming sms in your unity app.  Also you can easily register
and un-register the broadcast base on need.

In this tutorial I am going provide you a Unity Plugin(i.e:smsreader.jar) which
communicate b/w your unity app and android native callbacks. Below are the
steps to use it in your unity app :


1. Note: The package name which you have to use to access the plugin method is
               com.affle.smsreader

    Permission:  Add below permission inside your unity app manifest.xml file.
         <uses-permission android:name="android.permission.RECEIVE_SMS"/>
         <uses-permission android:name="android.permission.READ_SMS" />



2.  The plugin contains to static method which will be call from unity app :
          A. registerBroadcastReceiver() :  When your unity app launch we first need to
              call this method for registering the broadcast receiver. Below is code snapshot.
              These two methods and class are there in plugin we just need to add that
               plugin as a jar and call it.
            
        /**
  * This method register the Broadcast receiver
  * @param view
  */
 public static void registerBroadcastReceiver() {
    if (broadCastReceiver == null) {
  broadCastReceiver = new IncomingSms();
    }
    UnityPlayer.currentActivity.registerReceiver(broadCastReceiver,
  new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
 }

          B. unregisterBroadcastReceiver() : Whenever you want to stop reading incoming
               sms call this method or when your unity app goes in background.
 /**
  * This method un-register the Broadcast receiver
  * @param view
  */
 public static void unregisterBroadcastReceiver() {

  if (broadCastReceiver != null) {
   UnityPlayer.currentActivity.unregisterReceiver(broadCastReceiver);
   broadCastReceiver = null;
  }
 }

3. IncomingSms.java:
package com.affle.smsreader;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.util.Log;

import com.unity3d.player.UnityPlayer;

public class IncomingSms extends BroadcastReceiver {

 final SmsManager sms = SmsManager.getDefault();

 public void onReceive(Context context, Intent intent) {

  // Retrieves a map of extended data from the intent.
  final Bundle bundle = intent.getExtras();

  try {

   if (bundle != null) {

    final Object[] pdusObj = (Object[]) bundle.get("pdus");

    for (int i = 0; i < pdusObj.length; i++) {

     SmsMessage currentMessage = SmsMessage
       .createFromPdu((byte[]) pdusObj[i]);
     String phoneNumber = currentMessage
       .getDisplayOriginatingAddress();

     String message = currentMessage.getDisplayMessageBody();

     if (UnityPlayer.currentActivity != null) {
      UnityPlayer.UnitySendMessage("TextMessageListner",
        "OnMessageReceived", "" + message);
     }
    } // end for loop
   } // bundle is null

  } catch (Exception e) {
   Log.e("SmsReceiver", "Exception smsReceiver" + e);

  }
 }

}


Download the plugin from here : SmsReader.jar
Hope this will help some one.
Enjoy....
Happy Coding ... :)

Android RecyclerView and CardView tutorial | Android RecyclerView and CardView widgets | Android RecyclerView and CardView with backward compatibility

Hello Friends,
         Today, I am going to share my another post on Android RecyclerView and CardView.
This widgets come in android  latest release i.e Lollipop, Android 5.0 and API Level 21.
We can also add support on lower devices above API Level 7 by adding support library.
For creating complex Listview we need RecyclerView  and CardView.



Android RecyclerView: The advance version of Listview is RecyclerView, It is more
                                        advance and flexible. RecyclerView uses Layout manager for
managing position of item inside the recycler view. Recycler view provides three
built in Layout manager :

1. LinearLayoutManager : shows items in a vertical or horizontal scrolling list.
2. GridLayoutManager: shows items in a grid.
3. StaggeredGridLayoutManager: shows items in a staggered grid.

For more check this Link


CardView Widget:  It help us in showing information inside cards that have a consistent
                                  look across the platform. CardView widgets can have shadows and
                                  rounded corners.
 Note:
       1. To create a card with a shadow, use the card_view:cardElevation attribute. 
       2. To set the corner radius in your layouts, use the card_view:cardCornerRadius
           attribute.
      3. To set the corner radius in your code, use the CardView.setRadius method.
      4. To set the background color of a card, use the card_view:cardBackgroundColor
            attribute.


Here is Sample Code:

1. MainActivity.java

Android media store tutorial | List all sdcard audio |List all sdcard video | List all sdcard images

Hello Friends,
       Today, I am going to share my another post on Android Media Store. In this post
I am going to show you how to query media file like audio,images and video using
Android Media Store and Android Content Resolver .









For Listing all Images:
private void parseAllImages() {
        try {
            String[] projection = {MediaStore.Images.Media.DATA};
            cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                    projection, // Which columns to return
                    null,       // Return all rows
                    null,
                    null);

          
            int size = cursor.getCount();

            /*******  If size is 0, there are no images on the SD Card. *****/

            if (size == 0) {

            } else {

                int thumbID = 0;
                while (cursor.moveToNext()) {

                    int file_ColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);

                    /**************** Captured image details ************/

                    /*****  Used to show image on view in LoadImagesFromSDCard class ******/
                    String path = cursor.getString(file_ColumnIndex);

                    String fileName = path.substring(path.lastIndexOf("/") + 1, path.length());

                    MediaFileInfo mediaFileInfo = new MediaFileInfo();
                    mediaFileInfo.setFilePath(path);
                    mediaFileInfo.setFileName(fileName);
                    mediaFileInfo.setFileType(type);
                    mediaList.add(mediaFileInfo);
                }
            }


        } catch (Exception e) {
            e.printStackTrace();
        }
} 


For Listing all Video(.mp4)


private void parseAllVideo() {
        try {
            String name = null;
            String[] thumbColumns = {MediaStore.Video.Thumbnails.DATA,
                    MediaStore.Video.Thumbnails.VIDEO_ID};

            int video_column_index;
            String[] proj = {MediaStore.Video.Media._ID,
                    MediaStore.Video.Media.DATA,
                    MediaStore.Video.Media.DISPLAY_NAME,
                    MediaStore.Video.Media.SIZE};
            Cursor videocursor = getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
                    proj, null, null, null);
            int count = videocursor.getCount();
            Log.d("No of video", "" + count);
            for (int i = 0; i < count; i++) {
                MediaFileInfo mediaFileInfo = new MediaFileInfo();
                video_column_index = videocursor
                        .getColumnIndexOrThrow(MediaStore.Video.Media.DISPLAY_NAME);
                videocursor.moveToPosition(i);
                name = videocursor.getString(video_column_index);

                mediaFileInfo.setFileName(name);

                int column_index = videocursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                videocursor.moveToPosition(i);
                String filepath = videocursor.getString(column_index);

                mediaFileInfo.setFilePath(filepath);
                mediaFileInfo.setFileType(type);
                mediaList.add(mediaFileInfo);
                // id += " Size(KB):" +
                // videocursor.getString(video_column_index);


            }
            videocursor.close();

        } catch (Exception e) {
            e.printStackTrace();
        }
} 



For Listing All Audio


private void parseAllAudio() {
        try {
            String TAG = "Audio";
            Cursor cur = getContentResolver().query(
                    MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, null, null,
                    null);

            if (cur == null) {
                // Query failed...
                Log.e(TAG, "Failed to retrieve music: cursor is null :-(");

            }
            else if (!cur.moveToFirst()) {
                // Nothing to query. There is no music on the device. How boring.
                Log.e(TAG, "Failed to move cursor to first row (no query results).");

            }else {
                Log.i(TAG, "Listing...");
                // retrieve the indices of the columns where the ID, title, etc. of the song are

                // add each song to mItems

Android Turn on Bluetooth Tethering | Android enable tethering

Hello Friends ,
          Today, I am sharing my another blog on Bluetooth Tethering.  In this tutorial
we can programmatically turn on and off  Bluetooth Tethering.

 





















Here the code:

1. BluetoothTethering.java


package com.solutions.developer.android.com.bluetoothtethering;

import android.annotation.SuppressLint;
import android.bluetooth.BluetoothAdapter;

Android Trusting all certificates using HttpClient over HTTPS| Access all secure and in-secure https connection in Android and Java

Hello Friends,
          Today, I am going to share a blog post on "HTTPS". Using this blog we can easily access all
secure and non secure "HTTPS" connection in java as well as android too.


1. Add "InSecureSSLSocketFactory.java" class

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.http.conn.ssl.SSLSocketFactory;
public class InSecureSSLSocketFactory extends SSLSocketFactory {
    SSLContext sslContext = SSLContext.getInstance("TLS");

    public InSecureSSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
        super(truststore);

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        sslContext.init(null, new TrustManager[] { tm }, null);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
        return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
        return sslContext.getSocketFactory().createSocket();
    }
} 


2. Create a new HTTP client using the above InSecureSSLSocketFactory class, for making
     connection.

public HttpClient getNewHttpClient() {
    try {
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        trustStore.load(null, null);

        InSecureSSLSocketFactory sf = new InSecureSSLSocketFactory(trustStore);
        sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", sf, 443));

        ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

        return new DefaultHttpClient(ccm, params);
    } catch (Exception e) {
        return new DefaultHttpClient();
    }
}
3. Finally hitting the service url(https://) using getNewHttpClient() , which helps to feth data
    from server.

public static String networkHitForGetJsonData(String url)
{
 String websiteData = null;
 try {
  HttpParams httpParameters = new BasicHttpParams();
  HttpConnectionParams.setConnectionTimeout(httpParameters, 10000);
  HttpClient client = getNewHttpClient();
  URI uri = new URI(url);
  HttpGet method = new HttpGet(uri);
  method.addHeader("Content-Type", "text/html");
  HttpResponse res = client.execute(method);
  InputStream data = res.getEntity().getContent();
  websiteData = generateString(data);
  Log.e("response","response---> "+websiteData);
 } catch (ClientProtocolException e) {
  e.printStackTrace();
  websiteData = null;
 } catch (IOException e)
 {
  e.printStackTrace();
  websiteData = null;
 } catch (URISyntaxException e)
 {
  e.printStackTrace();
  websiteData = null;
 }
 return websiteData;
}  



Hope, this will helps some one.
Enjoy coding....... :)
