I am creating a calling application using TelephonyManager for getting state, BroadcastReceiver to notify the call and ITelephony for implementation.
-> I am able to answer and reject calls, But the problem is I cant hear caller voice in my device
Note : I have a rooted device and using android LOLLIPOP.
-> My app answers the incoming call properly after answering the call I am indenting to another activity to change the layout But, the intent is also not happening and I am not able to hear callers voice.
UPDATE : I have used handlers to update UI it is working very fine. If anyone have solution for getting caller audio please help me :)
Here is my code.
MainActivity.java :
public class MainActivity extends AppCompatActivity {
private static final int REQUEST_CALL = 1;
public String number1 = "";
private Button close;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
close = findViewById(R.id.close);
if (ContextCompat.checkSelfPermission(MainActivity.this,
Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(MainActivity.this,
Manifest.permission.MODIFY_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_CALL);
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.MODIFY_PHONE_STATE}, REQUEST_CALL);
}
close.setOnClickListener(v -> finishAndRemoveTask());
}}
call.java : (My BroadcastReceiver)
public class call extends BroadcastReceiver {
public String number1 = "";

.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
showToast(context, "Incoming call");
Intent in = new Intent(context, inComingCallActivity.class)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
in.putExtra("number", number1);
context.startActivity(in);
Log.d("inCall", number1);
} else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE)
