android u盘广播路径,Android设备6.0获取u盘挂载广播

一,清单文件静态注册广播

二,在广播中通过VolumeInfo判断挂载过程和卸载过程

public class UsbReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if (action.equals(VolumeInfo.ACTION_USB_DEVICE_ATTACHED)) {

Log.d("action===", "装载");

} else if (action.equals(VolumeInfo.ACTION_USB_DEVICE_DETACHED)) {

Log.d("action===", "卸载USB");

Toast.makeText(context, "USB设备移除", Toast.LENGTH_SHORT).show();

System.exit(0);

} else if (action.equals(VolumeInfo.ACTION_VOLUME_STATE_CHANGED)) {

int intExtra = intent.getIntExtra(VolumeInfo.EXTRA_VOLUME_STATE, VolumeInfo.STATE_UNMOUNTED);

if (intExtra == VolumeInfo.STATE_MOUNTED) {

Toast.makeText(UiUtils.getContext(), "发现USB设备", Toast.LENGTH_LONG).show()

}

}

}

}

public class VolumeInfo {

//卸载

public static final int STATE_UNMOUNTED = 0;

//状态监测

public static final int STATE_CHECKING = 1;

//挂载完成

public static final int STATE_MOUNTED = 2;

//只读

public static final int STATE_MOUNTED_READ_ONLY = 3;

//格式化

public static final int STATE_FORMATTING = 4;

//开始移除

public static final int STATE_EJECTING = 5;

//无法挂载

public static final int STATE_UNMOUNTABLE = 6;

//删除

public static final int STATE_REMOVED = 7;

//移除完成

public static final int STATE_BAD_REMOVAL = 8;

public static final String ACTION_VOLUME_STATE_CHANGED = "android.os.storage.action.VOLUME_STATE_CHANGED";

public static final String EXTRA_VOLUME_ID = "android.os.storage.extra.VOLUME_ID";

public static final String EXTRA_VOLUME_STATE = "android.os.storage.extra.VOLUME_STATE";

public static final String ACTION_USB_DEVICE_ATTACHED= "android.hardware.usb.action.USB_DEVICE_ATTACHED";

public static final String ACTION_USB_DEVICE_DETACHED= "android.hardware.usb.action.USB_DEVICE_DETACHED";

}
