Android Studio BroadcastReceiver 在 Android 6.0 中不工作

Question

所以我试图在我的应用中获取来电和短信详细信息。 我已经尝试了下面显示的代码，它适用于 Oneplus 6t (android 10)、Moto g plus (android 8) 和 Samsung M51 (android 10)，并且按预期工作。但在 Redmi Note 3 (android 6.0.1) 上使用时，SMS 部分有效，但来电部分无效。我曾尝试在 google 和 Stack Overflow 上查找，但尚未解决此问题。

AndroidManifest.xml

权限

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.READ_CALL_LOG"/>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.READ_SMS" />

接收者

<receiver android:name="com.earthenergy.earthenergyev.AnswerCallBroadcastReceiver" android:enabled="true">
        <intent-filter android:priority="100">
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
</receiver>

BroadcastReceiver 类

public class AnswerCallBroadcastReceiver extends BroadcastReceiver {

static PhonecallStartEndDetector listener;
String contactName;
Context context;
private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";


private SmsMessage getIncomingMessage(Object aObject, Bundle bundle) {
    SmsMessage currentSMS;

        String format = bundle.getString("format");
        currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format);

    }

    if (intent.getAction()
            .equals("android.intent.action.NEW_OUTGOING_CALL")) {
        listener.setOutgoingNumber(intent.getExtras().getString(
                "android.intent.extra.PHONE_NUMBER"));

        return;
    }

    if(intent.getAction().equals(SMS_RECEIVED)) {
        Bundle bundle = intent.getExtras();
        if(bundle != null) {
            Object[] pdus = (Object[]) bundle.get("pdus");
            SmsMessage currentSms;

                currentSms = getIncomingMessage(aObject, bundle);
                String sender = currentSms.getDisplayOriginatingAddress();

                Log.d("============","Sender: "+ sender);
                Toast.makeText(context,"Number: "+sender+"\nMessage: "+message,Toast.LENGTH_SHORT).show();
            }
        }
        return;
    }

    TelephonyManager telephony = (TelephonyManager) context
            .getSystemService(Context.TELEPHONY_SERVICE);
    telephony.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);

    int lastState = TelephonyManager.CALL_STATE_IDLE;
    boolean isIncoming;
    boolean isIncomingPicked;
    boolean isOutgoingStarted;
    String savedNumber; 

    public PhonecallStartEndDetector() {

    }

    public void setOutgoingNumber(String number) {
        savedNumber = number;
    }

    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        super.onCallStateChanged(state, incomingNumber);
        // state is changed
        if (lastState == state) {
            return;
        }

        switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                //an incoming call has been started
                String name = getContactName(incomingNumber, context);
                Toast.makeText(context, "Incoming Number: " + incomingNumber + "\nContact Name: " + name, Toast.LENGTH_SHORT).show();
                Log.d("==============", "Number: " + incomingNumber);
                Log.d("==============", "Name: " + name);
                isIncoming = true;
                savedNumber = incomingNumber;

                break;

        }

    }

在棉花糖版本的情况下，我们有一个叫做运行时权限的概念，它是在 Activity 中创建的，以便使用权限。运行时权限提供了一种在用户第一次运行活动时在运行时请求特定权限的方法。

这是你必须指定的两件事：

//为权限指定任意常数

public final static int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 11;

// 在 OnCreate 方法中指定以下代码

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

    // Here, thisActivity is the current activity
    if (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.READ_PHONE_STATE)
            != PackageManager.PERMISSION_GRANTED) {

        // Should we show an explanation?
        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.READ_CONTACTS)) {
        } else {
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.READ_PHONE_STATE},
                    MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
        }
    }
}

//指定在运行时弹出窗口询问用户权限的方法

@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_PHONE_STATE: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                } else {
            }
            return;
        }
    }
}

这将提供一种使用 Marshmallow 设备的方法
