tambahkan code berikut
 
 WebView webviewku;
    private static final String TAG = MainActivity.class.getSimpleName();
    private String mCM;
    private ValueCallback<Uri> mUM;
    private ValueCallback<Uri[]> mUMA;
    private final static int FCR=1;
    WebSettings websettingku;
 
    //select whether you want to upload multiple files (set 'true' for yes)
    private boolean multiple_files = false;
