android USBU盤 接入檢測

<receiver android:name="com.data_packet.RemovableDiskManagerReceiver">
    <intent-filter>
        <action android:name="RemovableDiskManagerReceiver" />

        <action android:name="android.intent.action.MEDIA_UNMOUNTED" />
        <action android:name="android.intent.action.MEDIA_CHECKING" />
        <action android:name="android.intent.action.MEDIA_EJECT" />
        <action android:name="android.intent.action.MEDIA_REMOVED" />
        <action android:name="android.intent.action.MEDIA_MOUNTED" />
        <action android:name="android.intent.action.MEDIA_BAD_REMOVAL" />
        <action android:name="android.intent.action.ACTION_MEDIA_SCANNER_STARTED" />
        <action android:name="android.intent.action.ACTION_MEDIA_SCANNER_FINISHED" />

        <data android:scheme="file" />
    </intent-filter>
</receiver>

若是是在註冊的靜態廣播通常必須含有以上的權限，這裏必須注意添加

<data android:scheme="file" />

若是在代碼中註冊廣播則必須iFilter.addDataScheme("file")

 

 

這樣接受廣播判斷U盤

public class RemovableDiskManagerReceiver extends BroadcastReceiver {
    public RemovableDiskManagerReceiver() {
    }
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.e("U","接受到廣播");
        // TODO Auto-generated method stub
        if( intent.getAction().equals(Intent.ACTION_MEDIA_MOUNTED )){
            Intent serviceintent=new Intent(context,USBCopySeverice.class);
            serviceintent.setAction(TAG_SET.USB_INTENT.USB_ADD);
            context.startService(serviceintent);
            LogUtils.eLog("U盤工具","U盤插入！");
        }else if(intent.getAction().equals(Intent.ACTION_MEDIA_UNMOUNTED)
                || intent.getAction().equals(Intent.ACTION_MEDIA_REMOVED)){

            Intent serviceintent=new Intent(context,USBCopySeverice.class);
            serviceintent.setAction(TAG_SET.USB_INTENT.USB_OFFLINE);
            context.startService(serviceintent);
            LogUtils.eLog("U盤工具","U盤拔出！");
        }

    };

}
