java.lang.SecurityException：权限拒绝：不允许发送广播android.hardware.usb.action.USB_STATE

Question

I am trying to make an apk to install in a device and manage usb state.

apk sends broadcast to device like...

Intent intent = new Intent(ACTION_USB_STATE);
sendBroadcast(intent);

In AndroidManifest.xml I stated permission part..

<uses-permission android:name="android.permission.BROADCAST_STICKY" />

but when error occours even though i already stated permission.

log is....

W/ActivityManager(  850): Permission Denial: not allowed to send broadcast android.hardware.usb.action.USB_STATE from pid=16082, uid=10109
E/AndroidRuntime(16082): FATAL EXCEPTION: main

I have no idea what i've done wrong..

Any clues will help.

Thank you.

You can find this declaration in framework/base/core/res/AndroidManifest.xml

This broadcast is in this section:

  24     <!-- ================================================ -->
  25     <!-- Special broadcasts that only the system can send -->
  26     <!-- ================================================ -->

 106     <protected-broadcast android:name="android.hardware.usb.action.USB_STATE" />

I believe you can understand this. You must be generating your own firmware to broadcast this intent.
