由于Android在更新日志中屏蔽了通话录音，目前没有官方支持的API来记录所有的呼入和呼出电话。然而，你可以使用TelephonyManager和BroadcastReceiver来监听电话状态，并在电话接通和挂断的时候记录相关信息。

下面是一个简单的示例代码：

1. 首先，添加权限到AndroidManifest.xml文件中：

2. 创建一个BroadcastReceiver类来监听电话状态：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;

public class PhoneStateReceiver extends BroadcastReceiver {

    private static final String TAG = "PhoneStateReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (action != null && action.equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
            // 获取拨打的电话号码
            String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Log.d(TAG, "拨打电话: " + phoneNumber);
        } else {
            // 通过TelephonyManager获取电话状态
            TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            if (telephonyManager != null) {
                int phoneState = telephonyManager.getCallState();
                switch (phoneState) {
                    case TelephonyManager.CALL_STATE_RINGING:
                        // 获取来电号码
                        String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
                        Log.d(TAG, "来电: " + incomingNumber);
                        break;
                    case TelephonyManager.CALL_STATE_IDLE:
                        // 电话挂断
                        Log.d(TAG, "电话挂断");
                        break;
                }
            }
        }
    }
}

3. 在MainActivity中注册广播接收器：

import android.Manifest;
import android.content.Intent;
import android.content.IntentFilter;
import android.content.pm.PackageManager;
import android.os.Bundle;

import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;

public class MainActivity extends AppCompatActivity {

    private static final int REQUEST_PERMISSION = 1;
    private PhoneStateReceiver phoneStateReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 动态请求权限
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED ||
                ActivityCompat.checkSelfPermission(this, Manifest.permission.PROCESS_OUTGOING_CALLS)
                != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.READ_PHONE_STATE, Manifest.permission.PROCESS_OUTGOING_CALLS},
                    REQUEST_PERMISSION);
        } else {
            registerPhoneStateReceiver();
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == REQUEST_PERMISSION) {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                registerPhoneStateReceiver();
            } else {
                // 权限被拒绝
            }
        }
    }

    private void registerPhoneStateReceiver() {
        phoneStateReceiver = new PhoneStateReceiver();
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(TelephonyManager.ACTION_PHONE_STATE_CHANGED);
        intentFilter.addAction(Intent.ACTION_NEW_OUTGOING_CALL);
        registerReceiver(phoneStateReceiver, intentFilter);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (phoneStateReceiver != null) {
            unregisterReceiver(phoneStateReceiver);
        }
    }
}

这个示例代码中，通过TelephonyManager和BroadcastReceiver来监听电话状态。在电话接通和挂断的时候，会在Logcat中打印相关信息。你可以根据自己的需求，将相关信息保存到数据库或文件中。

请注意，由于Android系统的限制，无法获取对方的通话内容。这个解决方案仅能记录电话的接通和挂断事件。
