So I'm having trouble trying to pass the greater of two entered numbers from one app and then have the receiver broadcast it in another. Here's code from the sending app:
public class MainActivity extends AppCompatActivity {
private EditText etFirst;
private EditText etSecond;
private Button btSend;
private int num;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etFirst = (EditText) findViewById(R.id.etFirst);
etSecond =(EditText) findViewById(R.id.etSecond);
btSend = (Button) findViewById(R.id.btSend);
btSend.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
int a = Integer.parseInt(etFirst.getText().toString());
int b = Integer.parseInt(etSecond.getText().toString());
if (a > b) {
num = a;
}
else {
num = b;
}
Intent intent = new Intent("com.numb.sending.intent");
intent.putExtra("com.numb.sending.intent.params", num);
sendBroadcast(intent);
}
});
}
}
Code from the receiving app:
public class MainActivity extends AppCompatActivity {
private Button btReceive;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btReceive = (Button) findViewById(R.id.btReceive);
btReceive.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MyReceiver.INTENT);
intent.putExtra(MyReceiver.PARAM);
sendBroadcast(intent);
}
});
}
}
My receiver:
public class MyReceiver extends BroadcastReceiver {
public static final String PARAM = "com.numb.sending.intent.params";
public static final String INTENT = "com.numb.sending.intent";
public MyReceiver() {
}
#Override
public void onReceive(Context context, Intent intent) {
if (intent.hasExtra(PARAM)) {
String value = intent.getStringExtra(PARAM);
Toast.makeText(context, value, Toast.LENGTH_SHORT).show();
}
}
}
Any help?

How do I change the phone call user interface? Like I have my own dialer layout and contacts layout but how do I change the calling UI. So, when the call is going on, can I remove the speaker button for example?
Here is my dialer scene that I have created: Dialer Picture
But I don't know how to edit this screen: Calling Picture
EDIT: I have already built the UI, I just can not get it to show during call!
Here is the code for as a simpler version:
public class MainActivity extends Activity {
private Button callBtn;
private Button dialBtn;
private EditText number;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
number = (EditText) findViewById(R.id.phoneNumber);
callBtn = (Button) findViewById(R.id.call);
dialBtn = (Button) findViewById(R.id.dial);
// add PhoneStateListener for monitoring
MyPhoneListener phoneListener = new MyPhoneListener();
TelephonyManager telephonyManager =
(TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
// receive notifications of telephony state changes
telephonyManager.listen(phoneListener,PhoneStateListener.LISTEN_CALL_STATE);
callBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
// set the data
String uri = "tel:"+number.getText().toString();
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(uri));
startActivity(callIntent);
}catch(Exception e) {
Toast.makeText(getApplicationContext(),"Your call has failed...",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});
dialBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
String uri = "tel:"+number.getText().toString();
Intent dialIntent = new Intent(Intent.ACTION_DIAL, Uri.parse(uri));
startActivity(dialIntent);
}catch(Exception e) {
Toast.makeText(getApplicationContext(),"Your call has failed...",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});
}
private class MyPhoneListener extends PhoneStateListener {
private boolean onCall = false;
#Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
// phone ringing...
Toast.makeText(MainActivity.this, incomingNumber + " calls you",
Toast.LENGTH_LONG).show();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
// one call exists that is dialing, active, or on hold
Toast.makeText(MainActivity.this, "on call...",
Toast.LENGTH_LONG).show();
//because user answers the incoming call
onCall = true;
break;
case TelephonyManager.CALL_STATE_IDLE:
// in initialization of the class and at the end of phone call
// detect flag from CALL_STATE_OFFHOOK
if (onCall == true) {
Toast.makeText(MainActivity.this, "restart app after call",
Toast.LENGTH_LONG).show();
// restart our application
Intent restart = getBaseContext().getPackageManager().
getLaunchIntentForPackage(getBaseContext().getPackageName());
restart.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(restart);
onCall = false;
}
break;
default:
break;
}
}
}
}
Thanks!
Add calling permission in manifest
<uses-permission android:name="android.permission.CALL_PHONE" />
Then need to check if call button pressed. for that use below intent filter
<intent-filter>
<action android:name="android.intent.action.CALL_BUTTON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
and when firing the UI
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.DIAL" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="tel" />
</intent-filter>
that means your calling activity in manifest will be something like this
<activity
android:name="com.example.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<!-- open activity when establishing a call -->
<intent-filter>
<action android:name="android.intent.action.CALL_PRIVILEGED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
</activity>
since API 23 it is possible, see Replacing default Phone app on Android 6 and 7 with InCallService arekolek.

As recommended, Below is the simplest java version.

The MainActivity just have a Button with an Intent redirecting to the DialerActivity.
Below is the DialerActivity. In this Activity, you will set your app as default in order to make call with your UI.
public class DialerActivity extends AppCompatActivity {
private static final int REQUEST_CALL_PHONE = 10;
EditText phoneNumber;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dialer);
phoneNumber = (EditText) findViewById(R.id.etNumber);
Button bCall = (Button) findViewById(R.id.btnCall);
offerReplacingDefaultDialer();
bCall.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
makeCall();
}
});
}
private void makeCall() {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
Uri uri = Uri.parse("tel:"+phoneNumber.getText().toString().trim());
Intent Call = new Intent(Intent.ACTION_CALL, uri);
//Toast.makeText(this, "Entered makeCall()", Toast.LENGTH_SHORT).show();
Log.i("debinf Dialer", "Entered makeCall()");
startActivity(Call);
} else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, REQUEST_CALL_PHONE);
}
}
private void offerReplacingDefaultDialer() {
if (getSystemService(TelecomManager.class).getDefaultDialerPackage() != getPackageName()) {
Intent ChangeDialer = new Intent(TelecomManager.ACTION_CHANGE_DEFAULT_DIALER);
ChangeDialer.putExtra(TelecomManager.EXTRA_CHANGE_DEFAULT_DIALER_PACKAGE_NAME, getPackageName());
startActivity(ChangeDialer);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == REQUEST_CALL_PHONE) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
makeCall();
} else {
Toast.makeText(this, "calling permission denied", Toast.LENGTH_LONG).show();
}
//return;
}
}
}
Here is how InCallService is implemented to manage the calls.
public class CallService extends InCallService {
OngoingCallObject ongoingCallObject;
#Override
public void onCallAdded(Call call) {
super.onCallAdded(call);
new OngoingCallObject().setCall(call);
//Intent CallAct = new Intent(this, CallActivity.class);
//startActivity(CallAct);
CallActivity.start(this, call);
}
#Override
public void onCallRemoved(Call call) {
super.onCallRemoved(call);
new OngoingCallObject().setCall(null);
}
}
Here is how the Object is implemented.
public class OngoingCallObject {
private static Call call;
private Object callback = new Callback() {
#Override
public void onStateChanged(Call call, int state) {
super.onStateChanged(call, state);
Log.i("debinf OngoingObj", "state is "+state);
}
};
public void setCall(Call call) {
if (this.call != null) {
this.call.unregisterCallback((Call.Callback)callback);
}
if (call != null) {
call.registerCallback((Call.Callback)callback);
Log.i("debinf OngoingObj", "call.getState() is "+call.getState());
}
this.call = call;
}
public void answer() {
//assert this.call != null;
if (this.call != null) {
this.call.answer(VideoProfile.STATE_AUDIO_ONLY);
}
}
public void hangup() {
//assert this.call != null;
if (this.call != null) {
this.call.disconnect();
}
}
}
And finally, the CallActivity where you launch your UI.
public class CallActivity extends AppCompatActivity {
TextView callInfo;
Button answer, hangup;
private String number;
private OngoingCallObject ongoingCall;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_call);
ongoingCall = new OngoingCallObject();
answer = (Button) findViewById(R.id.answer);
hangup = (Button) findViewById(R.id.hangup);
callInfo = (TextView) findViewById(R.id.callInfo);
number = Objects.requireNonNull(getIntent().getData().getSchemeSpecificPart());
callInfo.setText("Calling number : "+number);
answer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(CallActivity.this, "Answer button", Toast.LENGTH_SHORT).show();
ongoingCall.answer();
}
});
hangup.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ongoingCall.hangup();
}
});
}
public static void start(Context context, Call call) {
Intent intent = new Intent(context, CallActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(call.getDetails().getHandle());
context.startActivity(intent);
}
}
Here is the xml for DialerActivity: activity_dialer.xml

EDIT:
Actually the api 23 was release, check this answer. Keep in mind that some devices may not support this functionality.
PREVIEW:
The actual calling view (what you see during calls) CAN`T be changed.
To be more specific, some parts of android CAN NOT be overridden,
android has his core and as developers we have limited access to this
core. In your case you can override dialer but you can`t
override actual phone call view.
You can't do anything about this, until android team decided to share
this core feature with us (developers).
Build your own Dialer UI. Check this out.
You will need an Activity to handle the intent and then displaying a custom UI is your business.
MAINMENU.CLASS
public class MainMenu extends Activity {
ImageButton playButton;
ImageButton soundButton;
SoundPlayers soundPlayers;
MediaPlayer firstMenusMusic;
MediaPlayer arenaMusic;
MediaPlayer buttonSound;
boolean now_sound;
OthersIO othersIO;
//MediaPlayer firstMenusMusic;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_menu);
playButton = (ImageButton) findViewById(R.id.play_button);
soundButton = (ImageButton) findViewById(R.id.sfx_sound);
playButtonEvent();
}
private void playButtonEvent() {
playButton.setOnClickListener( new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(MainMenu.this, UserConfig.class);
MainMenu.this.finish();
startActivity(intent);
}
});
}
}
USERCONFIG.CLASS
public class UserConfig extends Activity {
ImageButton userConfigBack;
ImageButton userConfigOK;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_config);
....
}
public void chooseCharacter() {
....
}
public void back() {
userConfigBack.setOnClickListener( new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(UserConfig.this, MainMenu.class);
UserConfig.this.finish();
startActivity(intent);
}
});
}
public void OK() {
userConfigOK.setOnClickListener( new OnClickListener() {
#Override
public void onClick(View arg0) {

UserConfig.this.finish();
createPlayerData();

My problem is...
when I click play button on view from mainmenu.class. I can go to another page(go to view from userconfig.class). but when I click OK button in view from userconfig.class, I can't go to another page.
in USERCONFIG.CLASS change it to
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_config);
OK();
back();
}
call UserConfig.this.finish(); after startActivity()
I am setting two buttons on the screen. Whenever I press the first button it will disable the camera. ( as an admin )
