Java Convert 7bit Charset Octets to Readable String (From PDU SMS) -

-

i'm receiving sms gsm modem in pdu format; tp-user-data "c8329bfd06dddf72363904"
, is: "�2����r69", while sent sms "hello world!".

here java code:

    private string frompdutext(string pdusmstext) {     string endoding = pdusmstext.substring(0, 2);     pdusmstext = pdusmstext.substring(18);     byte bs[] = new byte[pdusmstext.length() / 2];     for(int = 0; < pdusmstext.length(); += 2) {         bs[i / 2] = (byte) integer.parseint(pdusmstext.substring(i, + 2), 16);     }     try {         string out = new string(bs, "ascii");     } catch(unsupportedencodingexception e) {         e.printstacktrace();         return "";     } {         return out;     } }

the input packed in 7-bits per character, means every 8 bytes encode 9 characters. constructing parser format can fun exercise or frustrating experience, depending on how take it. better off using library, , quick google search reveals several code examples.

i'm developing internal application uses bluetooth printing. want bluetooth pairing occur without user input. have managed working trapping android.bluetooth.device.action.pairing_request broadcast. in broadcast receiver call setpin method, , pairing works ok, bluetoothpairingdialog displayed second or two, disappears - see link below. https://github.com/android/platform_packages_apps_settings/blob/master/src/com/android/settings/bluetooth/bluetoothpairingdialog.java since broadcast non-ordered, can't call abortbroadcast() , , wondering if there other way prevent pairing dialog appearing. can hook window manager in way? i haven't been able come way without modifying sdk. if you're oem, it's easy (i'm on 4.3): in packages/apps/settings/androidmanifest.xml, comment intent filter pairing dialog: <activity android:name=".bluetooth.bluetoothpairingdialog" android:label="@string/bluetooth_pairing_request"
