android - 重启后短信广播接收器不工作

Question

我正在尝试从短信中获取电话号码和电话簿名称。当我从应用程序运行它并关闭应用程序时，它可以工作，但是，当我重新启动手机时，它就不起作用了。有人吗？

public class IncomingSMSReceiver extends BroadcastReceiver {
    private static final String queryString = "@zovi";
    private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";

    public void onReceive(Context _context, Intent _intent) {
        if (_intent.getAction().equals(SMS_RECEIVED)) {
            Intent intent = new Intent(_context, IncomingSMSService.class);
            _context.startService(intent);
            Bundle bundle = _intent.getExtras();
            if (bundle != null) {
                Object[] pdus = (Object[]) bundle.get("pdus");
                SmsMessage[] messages = new SmsMessage[pdus.length];
                for (int i = 0; i < pdus.length; i++)
                    messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                for (SmsMessage message : messages) {
                    String msg = message.getMessageBody();
                    Log.i("Poruka", msg);
                    String to = message.getOriginatingAddress();
                    String contactName = TelefonUtils.getContact(_context, to);
                    Log.i("Od", contactName + "\n" + to);
                }
            }
        }
    }
}

我的 XML:

<receiver android:name=".telefon.receivers.IncomingSMSReceiver"
          android:permission="android.permission.BROADCAST_SMS">
    <intent-filter android:priority="500">
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

Answer 1

在您的AndroidManifest.xml尝试添加<action android:name="android.intent.action.BOOT_COMPLETED" /> IncomingSMSReceiver 下的操作接收者标签。

开始Services或 BroadcastReceiver Android系统重启或启动后自动注册一个BroadcastReceiver到安卓android.intent.action.BOOT_COMPLETED系统事件。

试试这个代码。

<receiver android:name=".telefon.receivers.IncomingSMSReceiver"
 android:permission="android.permission.BROADCAST_SMS">
       <intent-filter android:priority="500">
       <action android:name="android.provider.Telephony.SMS_RECEIVED" />
       <action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>

如果您尝试过 android.intent.action.BOOT_COMPLETED那么它不适用于您的情况，因为您忘记添加 BOOT_COMPLETED你的 Intent
IncomingSMSReceiver它仅在 android.provider.Telephony.SMS_RECEIVED 的情况下有效因为你在 IncomingSMSReceiver 中使用了 if 条件.所以从

改变 if 条件

if (_intent.getAction().equals(SMS_RECEIVED)) {

到

if (_intent.getAction().equals(SMS_RECEIVED) || _intent.getAction().equals(BOOT_COMPLETED)) {

并定义private static final String BOOT_COMPLETED = "android.intent.action.BOOT_COMPLETED";在 IncomingSMSReceiver .以下是IncomingSMSReceiver的完整代码.

更改您的IncomingSMSReceiver代码:

public class IncomingSMSReceiver extends BroadcastReceiver {
    private static final String queryString = "@zovi";
    private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
    private static final String BOOT_COMPLETED = "android.intent.action.BOOT_COMPLETED";

    public void onReceive(Context _context, Intent _intent) {
        if (_intent.getAction().equals(SMS_RECEIVED) || _intent.getAction().equals(BOOT_COMPLETED)) {
            Intent intent = new Intent(_context, IncomingSMSService.class);
            _context.startService(intent);
            Bundle bundle = _intent.getExtras();
            if (bundle != null) {
                Object[] pdus = (Object[]) bundle.get("pdus");
                SmsMessage[] messages = new SmsMessage[pdus.length];
                for (int i = 0; i < pdus.length; i++)
                    messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                for (SmsMessage message : messages) {
                    String msg = message.getMessageBody();
                    Log.i("Poruka", msg);
                    String to = message.getOriginatingAddress();
                    String contactName = TelefonUtils.getContact(_context, to);
                    Log.i("Od", contactName + "\n" + to);
                }
            }
        }
    }
}

因此，当您的手机重新启动时，它将收到 android.intent.action.BOOT_COMPLETED并调用您的IncomingSMSReceiver接收器然后它将启动您的IncomingSMSService .

希望对你有帮助。
