IllegalArgumentException in ProgressDialog.dismiss

I received this crash report:

java.lang.IllegalArgumentException: View not attached to window manager
at android.view.WindowManagerImpl.findViewLocked(WindowManagerImpl.java:395)

Line 311 in ZhuangDictActivity is searchProgressDialog.dismiss() below:

public void onPageFinished(WebView view, String url) {
searchProgressDialog.dismiss();
onConfigurationChanged(ZhuangDictActivity.this.getResources().getConfiguration());
super.onPageFinished(view, url);
}


This is the ProgressDialog.show:

public void onPageStarted(WebView view, String url,
Bitmap favicon) {
searchProgressDialog.setMessage("Loading");
searchProgressDialog.show();
super.onPageStarted(view, url, favicon);
}


The crash occurred when the orientation is changed before the WebView finish loading.

Answer

You are simply dismissing, not checking whether it is showing or not. You'll have to check it first:

if (searchProgressDialog != null) {
    if (searchProgressDialog.isShowing()) {
        searchProgressDialog.dismiss();     
    }
}
