Question

我正在构建一个可以读取传入短信的应用。但是，我的BroadcastReceiver类无法检测/读取传入的SMS。我认为我的代码是正确的，但它仍然无法正常工作。

这是我的代码：

         You need a different API key for each encryption key, including the release key that is used to
         sign the APK for publishing.

</application>

[JAVA CLASS]

public class SmsReceiver extends BroadcastReceiver {

private static final String SMS_BUNDLE = "pdus";
private String smsBody, address;

@Override
public void onReceive(Context context, Intent intent) {

    Toast.makeText(context,"Test",Toast.LENGTH_LONG);
}



public void showNotification(Context context) {
    Vibrator v = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
            new Intent(context, MapsActivity.class), 0);

    v.vibrate(500);
    Intent in = new Intent("SmsMessage.intent.MAIN").
            putExtra("get_msg", address + ":" + smsBody);
    context.sendBroadcast(in);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(context)
                    //.setSmallIcon(R.drawable.notif1)
                    .setContentTitle("Attention!")
                    .setContentText("Car crash occure.");
    mBuilder.setContentIntent(contentIntent);
    mBuilder.setDefaults(Notification.DEFAULT_SOUND);
    mBuilder.setAutoCancel(true);
    NotificationManager mNotificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(1, mBuilder.build());

}

}

我想你忘了把.show()放在Toast的末尾。

Toast.makeText(context, "Test" ,Toast.LENGTH_LONG).show();

BroadcastReceiver无法检测/读取短信
