I would like to force a user to update to the newest version of the app if there is one available. For now, I am focusing only on Android devices and I do understand how much it is inadvisable to force such a thing on the user, but this is what I need to do.
I have found:
String currentVersion, latestVersion;
Dialog dialog;
private void getCurrentVersion(){
PackageManager pm = this.getPackageManager();
PackageInfo pInfo = null;
Code: Select all
try {
pInfo = pm.getPackageInfo(this.getPackageName(),0);
} catch (PackageManager.NameNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
currentVersion = pInfo.versionName;
new GetLatestVersion().execute(); }
private class GetLatestVersion extends AsyncTask {
Code: Select all
private ProgressDialog progressDialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected JSONObject doInBackground(String... params) {
try { //It retrieves the latest version by scraping the content of current version from play store at runtime
Document doc = Jsoup.connect(urlOfAppFromPlayStore).get();
latestVersion = doc.getElementsByAttributeValue
("itemprop","softwareVersion").first().text();
Code: Select all
}catch (Exception e){
e.printStackTrace();
}
return new JSONObject();
}
@Override
protected void onPostExecute(JSONObject jsonObject) {
if(latestVersion!=null) {
if (!currentVersion.equalsIgnoreCase(latestVersion))
showUpdateDialog();
}
else
background.start();
super.onPostExecute(jsonObject);
}
} private void showUpdateDialog(){
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("A New Update is Available");
builder.setPositiveButton("Update", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse
("market://details?id=yourAppPackageName")));
dialog.dismiss();
}
});
Code: Select all
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
background.start();
}
});
builder.setCancelable(false);
dialog = builder.show();
} but I do not know where to put it. Could I get sme help with this please?
