如何创建应用程序在Android Oreo中接收SMS

Question

我创建了一个可以接收SMS的应用程序。我已经在背景服务中使用广播接收器创建了此应用程序。现在，由于来自Android Oreo背景服务不存在，因此如何在Android Oreo中接收SMS。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" />

并申请您的代码;

第二，使用SMS的内容提供商：

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：必需的许可

<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，然后添加到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：实施接收器类

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;
                }

            }
        }
    }
}

步骤4：在主要活动中添加运行时许可

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;
        }
    }
}
