[`android.permission.ACCESS_NETWORK_STATE`][1] is needed for accessing [ConnectivityManager][2] (mainly for monitoring network connections in general), while [`android.permission.ACCESS_WIFI_STATE`][3] grants access to [WifiManager][4] (for managing all aspects of Wi-Fi connectivity in particular).

  [3]: http://developer.android.com/reference/android/Manifest.permission.html#ACCESS_WIFI_STATE
  [4]: http://developer.android.com/reference/android/net/wifi/WifiManager.html

`ACCESS_NETWORK_STATE` is required to check if you are connected to a network, it does not matter of what type it is (Wi-Fi, GPRS, UMTS, etc.).

`ACCESS_WIFI_STATE` is not required to prope for internet connections.

To answer most of the questions, yes you don’t need the `ACCESS_WIFI_STATE` if merely checking for connectivity.

Network state refers to cellular network connectivity.

Wifi state refers to the state of the phone&#39;s Wifi connection.

Is there a way I can echo the whole content of a .html file in PHP?

For example, I have some sample.html file, and I want to echo that filename, so its content should be displayed.

I want to use the traditional [C-style for loop][1] in Python. I want to loop through characters of a string, but also know what it is, and be able to jump through characters (e.g. `i = `5 somewhere in the code).

`for` with [`range`][2] doesn&#39;t give me the flexibility of an actual for loop.

I have following question. In my app there is a listview. I get itemname from listview and transfer it to the webview as a string. How to ignore case of this string and change spaces to underscores?

For example: `String itemname = &quot;First Topic&quot;`. I transfer it to the next activity and want to ignore case and change space to underscore (I want to get `first_topic` in result).
I get &quot;itemname&quot; in webviewactivity and want to do what I&#39;ve described for following code:

    String filename = bundle.getString(&quot;itemname&quot;) + &quot;.html&quot;;

Please, help.

I made a simple `AlertDialog` in my **Activity**:

    View view = layoutInflater.inflate(R.layout.my_dialog, null);
    AlertDialog infoDialog = new AlertDialog.Builder(MyActivity.this)
    					.setView(view)	
    					.create();
    
    infoDialog.show();

With above code, the **dialog** shows at the (about) the center of the screen. 

I am wondering, how can I customize the dialog position to make it showing just under the top Action Bar ? (Is there anyway to change the gravity or something of the dialog?) and how to do it based on my code??

I had my app in the android market with version code = 2 and version name = 1.1

However, while updating it today, I changed the version code = 3 in the manifest but by mistake changed my version name to 1.0.1 and uploaded the apk to the market.

Now, will the users of my app get an update notification on their phones or not? Or should I redo the process again?

I have figured out how to send and receive SMS messages.  To send SMS messages I had to call the `sendTextMessage()` and `sendMultipartTextMessage()` methods of the `SmsManager` class.  To receive SMS messages, I had to register a receiver in the `AndroidMainfest.xml` file.  Then I had to override the `onReceive()` method of the `BroadcastReceiver`.  I have included examples below.

**MainActivity.java**

    public class MainActivity extends Activity {
        private static String SENT = &quot;SMS_SENT&quot;;
        private static String DELIVERED = &quot;SMS_DELIVERED&quot;;
        private static int MAX_SMS_MESSAGE_LENGTH = 160;

        // ---sends an SMS message to another device---
        public static void sendSMS(String phoneNumber, String message) {
		
            PendingIntent piSent = PendingIntent.getBroadcast(mContext, 0, new Intent(SENT), 0);
            PendingIntent piDelivered = PendingIntent.getBroadcast(mContext, 0,new Intent(DELIVERED), 0);
            SmsManager smsManager = SmsManager.getDefault();
		
            int length = message.length();    		
            if(length &gt; MAX_SMS_MESSAGE_LENGTH) {
                ArrayList&lt;String&gt; messagelist = smsManager.divideMessage(message); 			
                smsManager.sendMultipartTextMessage(phoneNumber, null, messagelist, null, null);
            }
            else
                smsManager.sendTextMessage(phoneNumber, null, message, piSent, piDelivered);
            }
        }
        
        //More methods of MainActivity ...
    }



**SMSReceiver.java**

    public class SMSReceiver extends BroadcastReceiver {
        private final String DEBUG_TAG = getClass().getSimpleName().toString();
        private static final String ACTION_SMS_RECEIVED = &quot;android.provider.Telephony.SMS_RECEIVED&quot;;
        private Context mContext;
        private Intent mIntent;

        // Retrieve SMS
        public void onReceive(Context context, Intent intent) {
            mContext = context;
            mIntent = intent;
		
            String action = intent.getAction();

            if(action.equals(ACTION_SMS_RECEIVED)){
                
                String address, str = &quot;&quot;;
                int contactId = -1;
		
                SmsMessage[] msgs = getMessagesFromIntent(mIntent);
                if (msgs != null) {
                    for (int i = 0; i &lt; msgs.length; i++) {
                        address = msgs[i].getOriginatingAddress();
                        contactId = ContactsUtils.getContactId(mContext, address, &quot;address&quot;);
                        str += msgs[i].getMessageBody().toString();
                        str += &quot;\n&quot;;

                broadcastIntent.setAction(&quot;SMS_RECEIVED_ACTION&quot;);
                broadcastIntent.putExtra(&quot;sms&quot;, str);
                context.sendBroadcast(broadcastIntent);
            }
            
        }

        public static SmsMessage[] getMessagesFromIntent(Intent intent) {
            Object[] messages = (Object[]) intent.getSerializableExtra(&quot;pdus&quot;);
            byte[][] pduObjs = new byte[messages.length][];

            for (int i = 0; i &lt; messages.length; i++) {
                pduObjs[i] = (byte[]) messages[i];
            }
            byte[][] pdus = new byte[pduObjs.length][];
            int pduCount = pdus.length;
            SmsMessage[] msgs = new SmsMessage[pduCount];
            for (int i = 0; i &lt; pduCount; i++) {
                pdus[i] = pduObjs[i];
                msgs[i] = SmsMessage.createFromPdu(pdus[i]);
            }
            return msgs;
        }

However, I was wondering if you could send and receive MMS messages in a similar fashion.  After doing some research, many examples provided on blogs simply pass an `Intent` to the native Messaging application.  I am trying to send an MMS without leaving my application.  There doesn&#39;t seem to be a standard way of sending and receiving MMS.  Has anyone gotten this to work?

Also, I am aware that the SMS/MMS ContentProvider is not a part of the official Android SDK, but I was thinking someone may have been able to implement this.  Any help is greatly appreciated.

#Update

I have added a `BroadcastReceiver` to the `AndroidManifest.xml` file to receive MMS messages  

    &lt;receiver android:name=&quot;com.sendit.receivers.MMSReceiver&quot; &gt;
        &lt;intent-filter&gt;
            &lt;action android:name=&quot;android.provider.Telephony.WAP_PUSH_RECEIVED&quot; /&gt;

            &lt;data android:mimeType=&quot;application/vnd.wap.mms-message&quot; /&gt;
        &lt;/intent-filter&gt;
    &lt;/receiver&gt;

In the MMSReceiver class, the `onReceive()` method is only able to grab the phoneNumber that the message was sent from.  How do you grab other important things from an MMS such as the file path to the media attachment (image/audio/video), or the text in the MMS?

**MMSReceiver.java**

    public class MMSReceiver extends BroadcastReceiver {
        private final String DEBUG_TAG = getClass().getSimpleName().toString();

                    byte[] buffer2 = bundle.getByteArray(&quot;header&quot;);      
                    String header = new String(buffer2);
                    Log.d(DEBUG_TAG, &quot;header &quot; + header);

                    if(contactId != -1){
                        showNotification(contactId, str);
                    }

#Update #2

I have figured out how to pass extras in a `PendingIntent` to be received by a `BroadcastReceiver`:
https://stackoverflow.com/questions/14571564/android-pendingintent-extras-not-received-by-broadcastreceiver

However, the extra gets passed to the _SendBroadcastReceiver_ not the _SMSReceiver_.  How can I pass an extra to the _SMSReceiver_?

#Update #3

**Receiving MMS**

So after doing more research I saw some suggestions of registering a `ContentObserver`.  That way you can detect when there are any changes to the `content://mms-sms/conversations` Content Provider, consequently allowing you to detect incoming MMS.  Here is the closest example to get this to work that I have found: &lt;a href=&quot;http://www.anddev.org/other-coding-problems-f5/where-can-i-find-information-about-sending-receiving-mms-t51284.html&quot;&gt;Receiving MMS&lt;/a&gt;

However, there is a variable `mainActivity` of type `ServiceController`.  Where is the `ServiceController` class implemented?  Are there any other implementations of a registered `ContentObserver`?

**Sending MMS**

As for sending MMS, I have come across this example: &lt;a href=&quot;http://www.ziddu.com/download/14286605/SendMMS3.zip.html&quot;&gt;Send MMS&lt;/a&gt;

The problem is that I tried running this code on my Nexus 4, which is on Android v4.2.2, and I am receiving this error:

    java.lang.SecurityException: No permission to write APN settings: Neither user 10099 nor current process has android.permission.WRITE_APN_SETTINGS.

The error gets thrown after querying the `Carriers` ContentProvider in the `getMMSApns()` method of the `APNHelper` class.

    final Cursor apnCursor = this.context.getContentResolver().query(Uri.withAppendedPath(Carriers.CONTENT_URI, &quot;current&quot;), null, null, null, null);

Apparently you can&#39;t &lt;a href=&quot;https://stackoverflow.com/questions/13453640/read-apns-in-android-4-2&quot;&gt;read APNs in Android 4.2&lt;/a&gt;   

What is the alternative for all those applications which use mobile data to perform operations (like sending MMS) and don&#39;t know the default APN setting present in the device?

#Update #4

**Sending MMS**

I have tried following this example: &lt;a href=&quot;http://www.ziddu.com/download/14286605/SendMMS3.zip.html&quot;&gt;Send MMS&lt;/a&gt;

As @Sam suggested in his answer: 

`You have to add jsoup to the build path, the jar to the build path and import com.droidprism.*; To do that in android, add the jars to the libs directory first, then configure the project build path to use the jars already in the libs directory, then on the build path config click order and export and check the boxes of the jars and move jsoup and droidprism jar to the top of the build order.`

So now I no longer get the SecurityException errors.  I am testing now on a Nexus 5 on Android KitKat.  After running the sample code it gives me a 200 response code after the call to 

    MMResponse mmResponse = sender.send(out, isProxySet, MMSProxy, MMSPort);

However, I checked with the person I tried sending the MMS to. And they said they never received the MMS. 


Sending and Receiving SMS and MMS in Android (pre Kit Kat Android 4.4)

I have some receivers declared in my AndroidManifest :

    &lt;!-- no warning --&gt;
    &lt;receiver
        android:name=&quot;.receivers.TriggerMonitoringBootReceiver&quot;
        android:enabled=&quot;false&quot;&gt;
        &lt;intent-filter&gt;
            &lt;action android:name=&quot;android.intent.action.BOOT_COMPLETED&quot; /&gt;
        &lt;/intent-filter&gt;
    &lt;/receiver&gt;
    
    &lt;!-- no warning --&gt;
    &lt;receiver
        android:name=&quot;.receivers.ScanResultsReceiver&quot;
        android:enabled=&quot;false&quot;&gt;
        &lt;intent-filter&gt;
            &lt;action android:name=&quot;android.net.wifi.SCAN_RESULTS&quot; /&gt;
        &lt;/intent-filter&gt;
    &lt;/receiver&gt;
    
    &lt;!-- warning : Exported receiver does not require permission--&gt;
    &lt;receiver
        android:name=&quot;.receivers.BatteryMonitoringReceiver&quot;
        android:enabled=&quot;false&quot;&gt;
        &lt;intent-filter&gt;
            &lt;action android:name=&quot;@string/intent_action_setup_alarm&quot; /&gt;
            &lt;action android:name=&quot;@string/intent_action_cancel_alarm&quot; /&gt;
            &lt;action android:name=&quot;@string/intent_action_monitor&quot; /&gt;
        &lt;/intent-filter&gt;
    &lt;/receiver&gt;



The first one is meant to receive a `BOOT_COMPLETED` action. The second is meant to receive `android.net.wifi.SCAN_RESULTS`. The third one is meant to receive some actions I broadcast (intent_action_monitor) and some actions broadcasted by the `AlarmManager` (intent_action_setup_alarm etc).

Two questions:

 - Why don&#39;t I get the warning on all receivers? 
 - What permissions do I need to set *for receivers meant to receive from system services to correct the warning* (I understand what it is about and I don&#39;t want anyone to use my receivers anyway) ? _**Will**_ `exported=&quot;false&quot;` _**do** for boot receivers, wifi receivers, alarm receivers etc_?  
I thought of using a custom permission with `android:protectionLevel=&quot;signatureOrSystem&quot;` but the docs advise against both this [protection level][1] and [custom permissions][2]. So how I should handle this warning ?

Links to the docs and/or some code will be much appreciated.

In Eclipse we were able to add permissions in AndroidManifest.xml by going to AndroidManifest.xml-&gt;Permission-&gt; Adding permissions. 

How to add permissions in Android Studio? How can we get a list of all the permissions that we can add to an Activity ? 





Adding Permissions in AndroidManifest.xml in Android Studio?

I have a GPS app that already requests `ACCESS_FINE_LOCATION` permission in the manifest, now I want to add a library (MoPub)  that requires `ACCESS_COARSE_LOCATION`.

Am I correct in assuming that `ACCESS_FINE_LOCATION` is enough, and I can leave out `ACCESS_COARSE_LOCATION` from my manifest?

If I have ACCESS_FINE_LOCATION already, can I omit ACCESS_COARSE_LOCATION?

I&#39;m trying to make an app like, when a call comes to the phone I want to detect the number. Below is what I tried, but it&#39;s not detecting incoming calls. 

I want to run my `MainActivity` in background, how can I do that?

I had given the permission in `manifest` file.
  
    &lt;uses-permission android:name=&quot;android.permission.READ_PHONE_STATE&quot;/&gt;

Is there anything else should I provide in the manifest?

    public class MainActivity extends Activity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.test_layout);
       }

       public class myPhoneStateChangeListener extends PhoneStateListener {
           @Override
           public void onCallStateChanged(int state, String incomingNumber) {
               super.onCallStateChanged(state, incomingNumber);
               if (state == TelephonyManager.CALL_STATE_RINGING) {
                   String phoneNumber =   incomingNumber;
               }
           }
       }
    }

How to detect incoming calls, in an Android device?

The Android documentation contains the following description of the adb grant and adb revoke commands.  

    grant &lt;PACKAGE_PERMISSION&gt;

Grant permissions to applications. Only optional permissions the application has declared can be granted.

    revoke &lt;PACKAGE_PERMISSION&gt;

Revoke permissions to applications. Only optional permissions the application has declared can be revoked.

**Can anybody please give an example of the correct syntax to use them?**

I assume that &lt;PACKAGE_PERMISSION&gt; would be a permission like `android.permission.WRITE_EXTERNAL_STORAGE`, or perhaps just `WRITE_EXTERNAL_STORAGE`.  Well I tried those, and several others and I cannot get it to work.

I also tried (to no avail) several combinations of package and permission, which makes more sense to me (this sounds like a command that would modify a permission on one package, not all) 


How do I use adb grant or adb revoke?

Using adb, how can I find out the which permissions an Android application requires?

Because I want to display the permissions of multiple applications on different devices, viewing them in `Google Play` or `Settings` &gt; `Applications manager` requires too much manual work.
