我在主板上安装了Android 4.4设备，但它没有SIM卡模块。 请告诉我，我如何模仿来自我的应用程序的传入短信？ 我只想看到标准的通知短信传入短信。 我试过这个例子：
enter code here
private static void createFakeSms(Context context, String sender,
String body) {
byte[] pdu = null;
byte[] scBytes =PhoneNumberUtils.networkPortionToCalledPartyBCD("0000000000");
byte[] senderBytes = PhoneNumberUtils.networkPortionToCalledPartyBCD(sender);
int lsmcs = scBytes.length;
byte[] dateBytes = new byte[7];
Calendar calendar = new GregorianCalendar();
dateBytes[0] = reverseByte((byte) (calendar.get(Calendar.YEAR)));
dateBytes[1] = reverseByte((byte) (calendar.get(Calendar.MONTH) + 1));
dateBytes[2] = reverseByte((byte) (calendar.get(Calendar.DAY_OF_MONTH)));
dateBytes[3] = reverseByte((byte) (calendar.get(Calendar.HOUR_OF_DAY)));
dateBytes[4] = reverseByte((byte) (calendar.get(Calendar.MINUTE)));
dateBytes[5] = reverseByte((byte) (calendar.get(Calendar.SECOND)));
dateBytes[6] = reverseByte((byte) ((calendar.get(Calendar.ZONE_OFFSET) + calendar
.get(Calendar.DST_OFFSET)) / (60 * 1000 * 15)));
try {
ByteArrayOutputStream bo = new ByteArrayOutputStream();
bo.write(lsmcs);
bo.write(scBytes,0,scBytes.length);
bo.write(0x04);
bo.write((byte) sender.length());
bo.write(senderBytes,0,senderBytes.length);
bo.write(0x00);
bo.write(0x00); // encoding: 0 for default 7bit
bo.write(dateBytes,0,dateBytes.length);
try {
String sReflectedClassName = "com.android.internal.telephony.GsmAlphabet";
Class cReflectedNFCExtras = Class.forName(sReflectedClassName);
Method stringToGsm7BitPacked = cReflectedNFCExtras.getMethod(
"stringToGsm7BitPacked", new Class[] { String.class });
stringToGsm7BitPacked.setAccessible(true);
byte[] bodybytes = (byte[]) stringToGsm7BitPacked.invoke(null,
body);
bo.write(bodybytes);
} catch (Exception e) {
}
pdu = bo.toByteArray();
}finally {
}
Intent intent = new Intent();
intent.setClassName("com.android.mms",
"com.android.mms.transaction.SmsReceiverService");
intent.setAction("android.provider.Telephony.SMS_RECEIVED");
intent.putExtra("pdus", new Object[] { pdu });
intent.putExtra("format", "3gpp");
context.startService(intent);
}
private static byte reverseByte(byte b) {
return (byte) ((b & 0xF0) >> 4 | (b & 0x0F) << 4);
}
但是当我调用此函数时，我的应用程序崩溃了。 请帮帮我。
