Question

这是我的代码：

private PhoneStateListener mPhoneStateListener = new PhoneStateListener() {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        super.onCallStateChanged(state, incomingNumber);
        switch (state) {
        case TelephonyManager.CALL_STATE_OFFHOOK:
            break;
        case TelephonyManager.CALL_STATE_RINGING:
            break;
        case TelephonyManager.CALL_STATE_IDLE:
            break;
        }
    }
};

OnCreate事件：

mTelephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
        mTelephonyManager.listen(mPhoneStateListener,
                PhoneStateListener.LISTEN_CALL_STATE);

AndroidManifest.xml：

  <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
        <receiver android:name=".ServiceReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
        </receiver>

问题：当我接到电话时，我的应用程序会意外停止。这段代码有什么问题？

Answer 1

您使用的是服务还是活动？

如果你在一个Activity中做这件事，试着在onCreate（）中做两件事（用于PhoneStateListener和TelephonyManager的crate内部类）。
