I'm trying to add, in my android app, the legal notices for Google Maps v2 API, that can be obtained calling: GooglePlayServicesUtil.getOpenSourceSoftwareLicenseInfo()
So, my code is the following:
String LicenseInfo = GooglePlayServicesUtil
.getOpenSourceSoftwareLicenseInfo(getApplicationContext());
AlertDialog.Builder LicenseDialog = new AlertDialog.Builder(MyActivity.this);
LicenseDialog.setTitle("Lagal Notices");
LicenseDialog.setMessage(LicenseInfo);
LicenseDialog.show();
But when I execute this code, the system required about 10 seconds before the dialog is shown (considering that my device is a OnePlus One, it seems pretty strange) .
If I try to replace the LicenseInfo with a simple (shorter) string, the Dialog is open pretty fast. So I think that the problem is the length of the legal notices information retrieved from the Google play utils.
How can I solve this problem?

I had the same problem, but I found this on GitHub and based my solution on it. This does help but when the alert dialog shows, there is still a small hang on the UI thread but only for a few seconds.
https://github.com/wf9a5m75/phonegap-googlemaps-plugin/blob/master/src/android/plugin/google/maps/AsyncLicenseInfo.java
private class AsyncLoadLicenseInfo extends AsyncTask<Void,Void,AlertDialog.Builder>
{
@Override
protected void onPreExecute()
{
progressDialog = new ProgressDialog(context);
progressDialog.setIndeterminate(true);
progressDialog.setMessage(context.getResources().getString(R.string.LegalNoticesLoading));
progressDialog.setCancelable(false);
progressDialog.show();
}
@Override
protected AlertDialog.Builder doInBackground(Void... params)
{
String googleAttribution = GooglePlayServicesUtil.getOpenSourceSoftwareLicenseInfo(context);
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder
.setTitle(context.getResources().getString(R.string.AboutLegalNotices))
.setCancelable(false)
.setMessage(googleAttribution)
.setPositiveButton(context.getResources().getString(R.string.Close),null);
return builder;
}
@Override
protected void onPostExecute(AlertDialog.Builder builder)
{
AlertDialog attributionDialog = builder.create();
attributionDialog.setOnShowListener(new DialogInterface.OnShowListener()
{
@Override
public void onShow(DialogInterface dialog)
{
progressDialog.dismiss();
progressDialog = null;
}
});
attributionDialog.show();
}
}
As tasomaniac suggested, using WebView instead of TextView works without problems - there is just a small delay.
Here is the complete code to show the dialog:
private void legalDialog(){
String licenseInfo = GooglePlayServicesUtil.getOpenSourceSoftwareLicenseInfo(this);
licenseInfo = licenseInfo.replace("\n", "<br/>");
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(R.string.legal_notice);
WebView webView = new WebView(this);
webView.loadData("<html><body>"+licenseInfo+"</body></html>", "text/html", "utf-8");
WebSettings webSettings = webView.getSettings();
webSettings.setDefaultFontSize(12);
builder.setView(webView);
builder.setPositiveButton(R.string.dialog_close, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
final AlertDialog createDialog = builder.create();
createDialog.show();
}
Make sure to check if GooglePlayServicesUtil.getOpenSourceSoftwareLicenseInfo(this) doesn't return null, before calling legalDialog().
