targetSdkVersion 设置为 31 或 android 12 后 telephonyManager.listen 不起作用

Question

我将 targetSdkVersion 升级到 31 telephonyManager.listen 不起作用。考虑以下代码行：

\n

telephonyManager.listen(phoneStateListener,PhoneStateListener.LISTEN_CALL_STATE);

\n

logcat错误信息如下：

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

\n

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

\n

在定位低于 31 或 Android 12 之前，它运行得很好。在Android SDK 31上如何解决这个问题？提前致谢。

Answer 1

当目标 API 31 TelephonyManager.listen给出时：java.lang.SecurityException: listen

TelephonyManager.registerTelephonyCallback也是如此，除非禁用ENABLE_GET_CALL_STATE_PERMISSION_PROTECTION 。

开发者选项/应用程序兼容性更改/选择应用程序/启用 targetSdkVersion >= 31

由于TelephonyManager.listen在 API 级别 31 中已弃用，而TelephonyManager.registerTelephonyCallback在 API 级别 31 中添加，因此您应该编写如下代码：

更新callStateListener添加了和的示例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。

由于TelephonyCallback.CallStateListener需要Manifest.permission.READ_PHONE_STATE并且此权限的保护级别为危险，因此您应该按照本指南请求运行时权限：请求应用程序权限

Answer 2

您在提供 LISTEN_CALL_STATE 时调用监听将触发 onCallStateChanged() 回调。

telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);

正如您在文档中看到的，如果您的目标是 Android 31 或更高版本，则 onCallStateChanged() 需要 READ_PHONE_STATE。

需要权限：针对 API 级别 31+ 的应用程序的 READ_PHONE_STATE。

请参阅： https: //developer.android.com/reference/android/telephony/PhoneStateListener#onCallStateChanged(int,%20java.lang.String)

因此，要解决此问题，只需在调用监听调用之前请求权限（但仅当代码在 Android 31+ 上执行时），如下所示：

    // for API 31+: you need to first check for READ_PHONE_STATE permission to be able to listen to LISTEN_CALL_STATE
    if (Build.VERSION.SDK_INT >= 31)
    {
        if(ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED)
            telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
    }
    else // no permission needed
        telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);

Answer 3

这就是我这样做的方式：

    private suspend fun updateServiceState() {
        withContext(Dispatchers.Main) {
            telephonyManager.listen(object : PhoneStateListener() {
                override fun onServiceStateChanged(state: ServiceState) {
                    telephonyManager.listen(this, LISTEN_NONE)
                    ...
                }
            }, PhoneStateListener.LISTEN_SERVICE_STATE)

        }
    }

我的目标是 Android 12、API 31，但没有 READ_PHONE_STATE 权限
