BroadcastReceiver событие при монтирование USB флешки в Android

Как узнать что USB флешка подключена?

Можно подписаться на события.

Способ 1. Ручками.

В activity в методе onCreate() например.

IntentFilter filter = new IntentFilter(Intent.ACTION_MEDIA_MOUNTED);

//filter.addAction(Intent.ACTION_MEDIA_UNMOUNTED);

//filter.addAction(Intent.ACTION_MEDIA_SCANNER_FINISHED);

filter.addDataScheme("file"); //В документации не написано, но без нее не работает

registerReceiver(myMountReceiver, filter);

В onDestroy()

unregisterReceiver(myMountReceiver);

ну и 

private MountBroadcastReceiver myMountReceiver;

Способ 2. В манифесте

В файл AndroidManifest.xml необходимо добавить

        <receiver

            android:name=".MountBroadcastReceiver"

            android:enabled="true"

            android:label="MountBroadcastReceiver" >

            <intent-filter>

                <action android:name="android.content.Intent.MEDIA_MOUNTED" />

                <data android:scheme="file" />

            </intent-filter>

        </receiver>

Класс MountBroadcastReceiver

public class MountBroadcastReceiver extends BroadcastReceiver { public MountBroadcastReceiver(){ super(); }
@Override public void onReceive(Context context, Intent intent) { String mountDir = intent.getDataString(); if (intent.getAction().equals(Intent.ACTION_MEDIA_MOUNTED)) { Toast.makeText(context,"Media mounted to"+mountDir, Toast.LENGTH_LONG).show(); }}
