我想執行SQL SERVER & SQLite.ITs與WIFI網絡連接之間的複製。Android USB連接狀態;
我的問題是:網絡優先級USB(連接到PC),GPRS,WIFI。這是保證令。 Wifi & GPRS還行。 USB是一個問題。我如何識別連接到PC的Android設備?
public class DownlaodTableActivity extends Activity{
private int networkType;
private int signalStrengthInt;
private SignalStrength signalStrength;
private TelephonyManager telephonyInfo;
static boolean usbStatus = false;
public static BroadcastReceiver mReceiver1 = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, context.toString(),Toast.LENGTH_LONG).show();
String action = intent.getAction();
if (action.equals(Intent.ACTION_MEDIA_MOUNTED)) {
Toast.makeText(context, "SD Card mounted",Toast.LENGTH_LONG).show();
} else if (action.equals(Intent.ACTION_MEDIA_UNMOUNTED)) {
Toast.makeText(context, "SD Card unmounted",Toast.LENGTH_LONG).show();
} else if (action.equals(Intent.ACTION_MEDIA_SCANNER_STARTED)) {
Toast.makeText(context, "SD Card scanner started",Toast.LENGTH_LONG).show();
} else if (action.equals(Intent.ACTION_MEDIA_SCANNER_FINISHED)) {
Toast.makeText(context, "SD Card scanner finished",Toast.LENGTH_LONG).show();
} else if (action.equals(Intent.ACTION_MEDIA_EJECT)) {
Toast.makeText(context, "SD Card eject",Toast.LENGTH_LONG).show();
} else if(action.equals(Intent.ACTION_UMS_CONNECTED)){
Toast.makeText(context, "connected",Toast.LENGTH_LONG).show();
usbStatus =true;
} else if(action.equals(Intent.ACTION_UMS_DISCONNECTED)) {
Toast.makeText(context, "disconnected",Toast.LENGTH_LONG).show();
usbStatus =false;
}
if(UsbManager.ACTION_USB_ACCESSORY_ATTACHED.equals(action)) {
usbStatus =true;
}else{
usbStatus =false;
}
int level = intent.getIntExtra("level", 0);
Toast.makeText(context, "Battery Level is :"+level+" Please plugin charger!!!",Toast.LENGTH_LONG).show();
context.unregisterReceiver(this);
int rawlevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
int levels = -1;
if (rawlevel >= 0 && scale > 0) {
levels = (rawlevel * 100)/scale;
}
Toast.makeText(context, "Battery Level Remaining:"+levels+" %",Toast.LENGTH_LONG).show();
}
};
manager = (ConnectivityManager) getSystemService(DownlaodTableActivity.CONNECTIVITY_SERVICE);
is3g = manager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).isConnected();
isWifi = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnected();
telephonyInfo = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
telephonyInfo.listen(phoneState,PhoneStateListener.LISTEN_SIGNAL_STRENGTH);
networkType = telephonyInfo.getNetworkType();
if (usbStatus) {................}
else if (isWifi||is3g) { ................}
else if(networkType==TelephonyManager.NETWORK_TYPE_EDGE) { ...........}
和我的清單文件:
<receiver android:name=".admin.mReceiver1">
<intent-filter>
<action android:name="android.intent.action.ums_connected" />
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
<action android:name="android.hardware.usb.action.USB_DEVICE_DETACHED" />
</intent-filter>
<meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" android:resource="@xml/device_filter" />
<meta-data android:name="android.hardware.usb.action.USB_DEVICE_DETACHED" android:resource="@xml/device_filter" />
</receiver>
我想這也是辦法... http://pastie.org/3019828
請告訴我,爲什麼它沒有考慮USBSttaus = TRUE; 我在PC上連接Android,但仍顯示USB設備的連接狀態爲false。
請幫忙解決這個問題。
在此先感謝;
它更重要的是如何將你傳送過來的數據USB to PC – ingsaurabh 2011-12-15 05:05:23
我真的不知道我要如何進行preocess。在我的本地PC上運行它的服務。然後它會自動下載數據。 – Piraba 2011-12-15 05:30:08
