This is regarding the question asked by Starter.

The problem with your code is that you are not passing the number properly.

The code should be:

private OnClickListener next = new OnClickListener() {

     public void onClick(View v) {
        EditText num=(EditText)findViewById(R.id.EditText01); 
        String number = "tel:" + num.getText().toString().trim();
        Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(number)); 
        startActivity(callIntent);
    }
};

Do not forget to add the permission in manifest file.

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

or

<uses-permission android:name="android.permission.CALL_PRIVILEGED"></uses-permission>

for emergency number in case DIAL is used.

I found the EndCallListener the most functional example  to get the behaviour described  finish    call  restart   I added a few  SharedPreferences so the Listener had a reference to manage this behaviour    My OnClick  initialise and EndCallListener only respond to calls from app   Other calls ignored   import android content Intent  import android content SharedPreferences  import android

When starting your call  it looks fine   There is a difference between android 11  and down in bringing your app to the front though   Android 10 or less you need to start a new intent  android 11  you simply use BringTaskToFront  In the call state IDLE   if  Build VERSION SDK INT  gt   11        ActivityManager am    ActivityManager  activity getSystemService Activity ACTIVITY SERVICE       am moveTaskToFront MyActivity MyActivityTaskId  ActivityManager MOVE TASK WITH HOME     else       Intent intent   new Intent activity  MyActivity class       activity startActivity intent       I set the MyActivity MyActivityTaskId when making the call on my activity like so  it this doesnt work  set this variable on the parent activity page of the page you want to get back to   MyActivity MyActivityTaskId   this getTaskId      MyActivityTaskId is a static variable on my activity class  public static int MyActivityTaskId   0    I hope this will work for you  I use the above code a bit differently  I open my app as soon as the call is answered sothat the user can see the details of the caller   I have set some stuff in the AndroidManifest xml as well     Dont really know if this makes a difference    lt activity android name  MyActivity  android taskAffinity    android launchMode  singleTask    gt    and permissions    lt uses-permission android name  android permission GET TASKS    gt   lt uses-permission android name  android permission REORDER TASKS    gt    Please ask questions if or when you get stuck

To return to your Activity  you will need to listen to TelephonyStates  On that listener you can send an Intent to re-open your Activity once the phone is idle   At least thats how I will do it

When PhoneStateListener is used  one need to make sure PHONE STATE IDLE following a PHONE STATE OFFHOOK is used to trigger the action to be done after the call  If the trigger happens upon seeing PHONE STATE IDLE  you will end up doing it before the call  Because you will see the state change PHONE STATE IDLE - gt  PHONE STATE OFFHOOK - gt  PHONE STATE IDLE

Steps   1 Add the required permissions in the Manifest xml file    lt  --For using the phone calls -- gt   lt uses-permission android name  android permission CALL PHONE    gt   lt  --For reading phone call state-- gt   lt uses-permission android name  android permission READ PHONE STATE    gt    2 Create a listener for the phone state changes   public class EndCallListener extends PhoneStateListener    Override public void onCallStateChanged int state  String incomingNumber        if TelephonyManager CALL STATE RINGING    state              if TelephonyManager CALL STATE OFFHOOK    state              wait for phone to go offhook  probably set a boolean flag  so you know your app initiated the call            if TelephonyManager CALL STATE IDLE    state              when this state occurs  and your flag is set  restart your app     Intent i   context getPackageManager   getLaunchIntentForPackage                              context getPackageName           For resuming the application from the previous state     i addFlags Intent FLAG ACTIVITY SINGLE TOP          Uncomment the following if you want to restart the application instead of bring to front        i addFlags Intent FLAG ACTIVITY CLEAR TOP       context startActivity i               3 Initialize the listener in your OnCreate  EndCallListener callListener   new EndCallListener    TelephonyManager mTM    TelephonyManager this getSystemService Context TELEPHONY SERVICE   mTM listen callListener  PhoneStateListener LISTEN CALL STATE     but if you want to resume your application last state or to bring it back from the back stack  then replace FLAG ACTIVITY CLEAR TOP with FLAG ACTIVITY SINGLE TOP  Reference this Answer

Inside PhoneStateListener after seeing the call is finished better use   Intent intent   new Intent CallDispatcherActivity this  CallDispatcherActivity class   intent setFlags Intent FLAG ACTIVITY CLEAR TOP   startActivity intent     Where CallDispatcherActivity is the activity where the user has launched a call  to a taxi service dispatcher  in my case   This just removes Android telephony app from the top  the user gets back instead of ugly code I saw here

This is solution from my point of view   ok setOnClickListener this    Override public void onClick View view        if view    ok           Intent intent   new Intent Intent ACTION CALL           intent setData Uri parse  tel     num            activity startActivity intent            Of course in Activity  class  definition you have to implement View OnClickListener

We had the same problem and managed to solve it by using a PhoneStateListener to identify when the call ends  but additionally we had to finish   the original activity before starting it again with startActivity  otherwise the call log would be in front of it

Here is my example  first the user gets to write in the number he she wants to dial and then presses a call button and gets directed to the phone  After call cancelation the user gets sent back to the application  In order to this the button needs to have a onClick method   makePhoneCall  in this example  in the xml  You also need to register the permission in the manifest    Manifest   lt uses-permission android name  android permission CALL PHONE  gt  lt  uses-permission gt   lt uses-permission android name  android permission READ PHONE STATE    gt    Activity  import android net Uri  import android os Bundle  import android app Activity  import android content Intent  import android view View  import android widget EditText  import android widget Toast   public class PhoneCall extends Activity        EditText phoneTo        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout activity phone call            phoneTo    EditText  findViewById R id phoneNumber              public void makePhoneCall View view                try               String number   phoneTo getText   toString                Intent phoneIntent   new Intent Intent ACTION CALL               phoneIntent setData Uri parse  tel    number                startActivity phoneIntent               catch  android content ActivityNotFoundException ex                Toast makeText PhoneCall this                       Call failed  please try again later    Toast LENGTH SHORT  show                         XML    lt EditText         android layout width  wrap content          android layout height  wrap content          android inputType  phone          android ems  10          android id    id phoneNumber          android layout marginTop  67dp          android layout below    id textView          android layout centerHorizontal  true    gt        lt Button         android layout width  fill parent          android layout height  wrap content          android text  Call          android id    id makePhoneCall          android onClick  makePhoneCall          android layout alignParentBottom  true          android layout centerHorizontal  true    gt

use a PhoneStateListener to see when the call is ended   you will most likely need to trigger the listener actions to wait for a the call to start  wait until changed from PHONE STATE OFFHOOK to PHONE STATE IDLE again  and then write some code to bring your app back up on the IDLE state     you may need to run the listener in a service to ensure it stays up and your app is restarted   some example code   EndCallListener callListener   new EndCallListener    TelephonyManager mTM    TelephonyManager this getSystemService Context TELEPHONY SERVICE   mTM listen callListener  PhoneStateListener LISTEN CALL STATE     Listener definition   private class EndCallListener extends PhoneStateListener        Override     public void onCallStateChanged int state  String incomingNumber            if TelephonyManager CALL STATE RINGING    state                Log i LOG TAG   RINGING  number      incomingNumber                     if TelephonyManager CALL STATE OFFHOOK    state                  wait for phone to go offhook  probably set a boolean flag  so you know your app initiated the call              Log i LOG TAG   OFFHOOK                      if TelephonyManager CALL STATE IDLE    state                  when this state occurs  and your flag is set  restart your app             Log i LOG TAG   IDLE                        In your Manifest xml file add the following permission    lt uses-permission android name  android permission READ PHONE STATE   gt
