Android: Detecting USB

Question

Is there any way to know(programmatically) in your Activity/Application that the user has connected your phone to PC through USB?

Answer 1

If all you want to do is detect whether you have access to the sdcard, then the following will work:

private boolean canWriteToFlash() {
    String state = Environment.getExternalStorageState();
    if (Environment.MEDIA_MOUNTED.equals(state)) {
        return true;
    } else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
        // Read only isn't good enough
        return false;
    } else {
        return false;
    }
}
