java - 在 targetSdkVersion 设置为 31 或 android 12 后，telephonyManager.listen 不起作用

Question

在我将 targetSdkVersion 升级到 31 后，telephonyManager.listen 不起作用。考虑以下代码行:
telephonyManager.listen(phoneStateListener,PhoneStateListener.LISTEN_CALL_STATE);
logcat 错误信息如下:

我在 Android Manifiest 文件上添加了以下权限，但仍然无法正常工作。

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

在低于 31 或 Android 12 之前，它运行良好。如何在 Android SDK 31 上解决这个问题？提前致谢。

当目标 API 31 TelephonyManager.listen给出:java.lang.SecurityException: listenTelephonyManager.registerTelephonyCallback 也是如此, 除非 ENABLE_GET_CALL_STATE_PERMISSION_PROTECTION被禁用。
开发人员选项/应用程序兼容性更改/选择应用程序/为 targetSdkVersion >= 31 启用
从 TelephonyManager.listen在 API 级别 31 和 TelephonyManager.registerTelephonyCallback 中已弃用在 API 级别 31 中添加，您应该编写如下代码:
更新 为 callStateListener 添加了示例和 phoneStateListener

    private void registerCallStateListener() {
        if (!callStateListenerRegistered) {
            TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
                if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED) {
                    telephonyManager.registerTelephonyCallback(getMainExecutor(), callStateListener);
                    callStateListenerRegistered = true;
                }
            } else {
                telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
                callStateListenerRegistered = true;
            }
        }
    }

    @RequiresApi(api = Build.VERSION_CODES.S)
    private static abstract class CallStateListener extends TelephonyCallback implements TelephonyCallback.CallStateListener {
        @Override
        abstract public void onCallStateChanged(int state);
    }

    private boolean callStateListenerRegistered = false;

    private CallStateListener callStateListener = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) ?
            new CallStateListener() {
                @Override
                public void onCallStateChanged(int state) {
                    // Handle call state change
                }
            }
            : null;

    private PhoneStateListener phoneStateListener = (Build.VERSION.SDK_INT < Build.VERSION_CODES.S) ?
            new PhoneStateListener() {
                @Override
                public void onCallStateChanged(int state, String phoneNumber) {
                    // Handle call state change
                }
            }
            : null;

TelephonyCallback.CallStateListener

PhoneStateListener .

因为 TelephonyCallback.CallStateListener需要 Manifest.permission.READ_PHONE_STATE并且此权限具有危险的保护级别，您应该按照本指南请求运行时权限: Request app permissions
