如何在 Android 8.0 Oreo 上以编程方式结束来电 [英] How to end an incoming call programmatically on Android 8.0 Oreo

问题描述

在 Android 7.1 之前，可以通过使用 ITelephony.endCall() 方法并为您的应用授予权限 来结束来电android.permission.CALL_PHONE 和 android.permission.READ_PHONE_STATE.

Up to Android 7.1 it was possible to end an incoming call by using the ITelephony.endCall() method and giving your app the permissions android.permission.CALL_PHONE and android.permission.READ_PHONE_STATE.

在 Android 8.0 Oreo (API 26) 上执行相同操作时，我收到此错误

When doing the same on Android 8.0 Oreo (API 26), i get this error

12-09 18:11:25.195 16833-16833/li.doerf.leavemealoneE/TelephonyServiceCallHangup:缺少权限 MODIFY_PHONE_STATE，不能挂断电话

12-09 18:11:25.195 16833-16833/li.doerf.leavemealone E/TelephonyServiceCallHangup: Missing permission MODIFY_PHONE_STATE, cannot hangup call

由于 MODIFY_PHONE_STATE 是受保护的权限，我的应用无法获取它.有没有办法在 Android 8.0+ 上以编程方式结束来电?

Since MODIFY_PHONE_STATE is a protected permission, my app cannot get it. Is there a way to programmatically end an incoming call on Android 8.0+?

推荐答案

将应用目标和编译级别更改为 28.

Changed App Target and Compile level to 28.

以及以下权限.

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

在 MyPhoneStateListener 类的 onCallStateChanged 方法中添加以下代码.

Add the following code on onCallStateChanged method of MyPhoneStateListener class.

public void endCall() {
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.P) {
            TelecomManager tm = (TelecomManager) mcontext.getSystemService(Context.TELECOM_SERVICE);
            if (tm != null) {
                boolean success = tm.endCall();
            }
            // success == true if call was terminated.
        } else {
            if (mcontext != null) {
                TelephonyManager telephony = (TelephonyManager) mcontext
                        .getSystemService(Context.TELEPHONY_SERVICE);
                try {
                    Class c = Class.forName(telephony.getClass().getName());
                    Method m = c.getDeclaredMethod("getITelephony");
                    m.setAccessible(true);
                    telephonyService = (ITelephony) m.invoke(telephony);
                    // telephonyService.silenceRinger();
                    telephonyService.endCall();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }
