Question

我创建了一个可以接收短信的应用程序。我已经使用后台服务中的广播接收器创建了此应用。现在，由于不存在来自android oreo的后台服务，因此如何在android oreo中接收短信。请帮助我。

Answer 1

首先，您应该请求权限：

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

并在您的代码中应用；

第二，使用短信内容提供商：

Uri SMS_INBOX = Uri.parse("content://sms/");

ContentResolver cr = getContentResolver();
String[] projection = new String[] { "body" };//"_id", "address", "person",, "date","type
String where = "";// your condition
Cursor cur = cr.query(SMS_INBOX, projection, where, null, "date desc");
if (null == cur)
    return;
while(cur.moveToNext()) {
    // your code
}

最后，实现您的功能；

步骤1：所需权限

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />

步骤2：制作一个名为SmsReceiver的接收器类，并将其添加到Mainifest.xml文件中。

<receiver android:name=".SmsReceiver" android:enabled="true" android:exported="true">
    <intent-filter android:priority="2147483647">
         <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

步骤3：实现接收器类

public class SmsReceiver extends BroadcastReceiver {

    private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
    public static final String SMS_BUNDLE = "pdus";

    String smsReceiveNumber, smsReceivedBody;

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(SMS_RECEIVED)) {
            Bundle intentExtras = intent.getExtras();
            if (intentExtras != null) {
                Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
                String smsMessageStr = "";
                for (int i = 0; i < sms.length; ++i) {
                    SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);

                    String smsBody = smsMessage.getMessageBody().toString();
                    String address = smsMessage.getOriginatingAddress();

                    smsMessageStr += "SMS From: " + address + "\n";
                    smsMessageStr += smsBody + "\n";

                    smsReceiveNumber = address;
                    smsReceivedBody = smsBody;
                }


            }
        }

    }
}

第4步：在主要活动中添加运行时权限

public class MainActivity extends AppCompatActivity {

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

        if (!havePermission()) {
            havePermission();
        }

    }

    public boolean havePermission() {
        if (Build.VERSION.SDK_INT >= 23) {
            if (checkSelfPermission(Manifest.permission.RECEIVE_SMS) == PackageManager.PERMISSION_GRANTED) {
                return true;
            } else {
                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.RECEIVE_SMS}, 1);
                return false;
            }
        } else {
            return true;
        }
    }
}
