问题描述
我正在创建一个调用应用程序，使用 TelephonyManager 获取状态，使用 broadcastReceiver 通知呼叫并使用 ITelephony 进行实现。
-> 我可以接听和拒接电话，但问题是我在设备中听不到来电者的声音
注意：我有一个 root 设备并使用 android LOLLIPOP。
-> 我的应用在接听电话后正确接听来电，我正在缩进另一个活动以更改布局但是，意图也没有发生，我无法听到来电者的声音。
UPDATE ：我使用处理程序来更新 UI，它工作得很好。如果有人有获取来电者音频的解决方案，请帮助我:)
这是我的代码。
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());
}}

所以，我需要帮助了解为什么我无法听到来电者的声音并且在接听电话后没有发生意图。
我已经提供了我的输入代码，任何帮助都会非常有用，提前致谢。
