I have an Android application. Сan I get the version of VideoView programmatically?
Maybe there's a way to find it using the firmware version?
please try this code :
try {
PackageInfo pInfo = this.getPackageManager().getPackageInfo("video player package name", 0);
String version = pInfo.versionName;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}

I have a Marshmallow device. It has custom built SW.
I have seen the build.prop file. There I can perceive the Software version name comes from ro.custom.build.version
My question is - how can I get the "ro.custom.build.version" information programmatically in my application ?
I got the answer. It is very simple -
First, I created a function to read from SystemProperties.
public String getSystemProperty(String key) {
String value = null;
try {
value = (String) Class.forName("android.os.SystemProperties")
.getMethod("get", String.class).invoke(null, key);
} catch (Exception e) {
e.printStackTrace();
}
return value;
}
And then called the function with "ro.custom.build.version" as a key
getSystemProperty("ro.custom.build.version");
Special thanks to #sasikumar for giving me the hint
You have to do as below :
PackageInfo pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
String version = pInfo.versionName;
To get the Version code, Use as below :
int verCode = pInfo.versionCode;
Check android.os.Build.VERSION. You can use INCREMENTAL.
A app and B app same app.
only different version
recently my phone have A app
and my server have B app.
I want if my server have recently version
change app .
How can I do?
use BufferedReader ?
thanks
this will get the current App version
PackageManager manager = context.getPackageManager();
PackageInfo pInfo = null;
try {
pInfo = manager.getPackageInfo(context.getPackageName(), 0);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
String cuurentVersion = pInfo.versionName;
and you can do some version check on server by a webservice.. That you have to do
e.g If user clicks on check for update then action should be..
Check version of my application in market
If my application's current version and market version are not same then I just want to give a dialog of "Upgrade now".
Also wants to know is there any possibilities without WebServices for this aciton? because I have referred some answers with WebServices, instead of it is there any possibilities then please share your knowledge.
Thanks in advance :)
You can't get version of android market app, I wanna explain this... You can get current version of the app with this code:
public int getAppVersion(Context context) {
try {
PackageInfo packageInfo = context.getPackageManager()
.getPackageInfo(context.getPackageName(), 0);
return packageInfo.versionCode;
} catch (PackageManager.NameNotFoundException e) {
// should never happen
throw new RuntimeException("Could not get package name: " + e);
}
}
If you want to know the version that have android market, that it's impossible, you need to think alternative, webservice how you say... In my case, for example, I save the version of Android Market in my server, when I sync my app with my server I obtain the AndroidMarket version then in this moment I can compare versions and apply the necessary code, in your case showDialog.
Not exist alternative that you can get version from you android app market, why? The apps have their code and not it's the same code for all apps...
Tell me if I helped you and good programming!
public String getLatestVersionNumber()
{
String versionNumber = "0.0.0";
try
{
Document doc = Jsoup.connect("<market:urlofparticularapp>").get();
Elements changeLog = doc.select("div.clDesc");
for (Element div : changeLog)
{
String divText = div.text();
if (divText.contains("Version"))
{
return divText.split(" ")[1];
}
}
}
catch (IOException e)
{
e.printStackTrace();
}
return versionNumber;
}
Download Library of Jsoup from http://jsoup.org/download
As I know there is no way to get current version of market Application.
But i am doing this in my application by using of server.
I am putting the Upcoming app version on server and getting the current app version from app By using this code
oldVersion = Splash.this.getPackageManager().getPackageInfo(getPackageName(), 0).versionName;
When app will launch then we will get the version from server and compare with app version for old user. If version will mismatch then give the popup for update for application using this code
Uri uri = Uri.parse("market://details?id=" + MainActivity.this.getPackageName());
Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
try {
MainActivity.this.startActivity(goToMarket);
} catch (ActivityNotFoundException e) {
MainActivity.this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + MainActivity.this.getPackageName())));
}
We have a set of 3-5 android applications that we have developed for an enterprise to integrate with our back-end. How do we create an installer system that upgrades applications automatically. We were thinking of getting version numbers and querying the backend to get current versions and downloading them.
How do I get the version number of an application in Android?
ApplicationInfo info = getApplicationInfo();
try {
info = getPackageManager().getApplicationInfo(info.packageName, PackageManager.GET_META_DATA);
} catch (NameNotFoundException e) {
e.printStackTrace();
}
Any pointers will be most useful.
Thanks

Using the function below you can get the current Version Name or No for the application.
This you can check against that of the app at server side and if needed you can upgrade app.
public static function String getVersionName(Context context, Class cls) {
try {
ComponentName comp = new ComponentName(context, cls);
PackageInfo pinfo = context.getPackageManager().getPackageInfo(comp.getPackageName(), 0);
return pinfo.versionName;
} catch (android.content.pm.PackageManager.NameNotFoundException e) {
return null;
}
}
Is there a simple way to find the current version of my application from within it? I would like to add the version string to the about screen.
You should check this question.
I am doing it this way:
try {
String pkg = mContext.getPackageName();
mVersionNumber = mContext.getPackageManager().getPackageInfo(pkg, 0).versionName;
} catch (NameNotFoundException e) {
mVersionNumber = "?";
}
please try out this.
PackageInfo pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
version = pInfo.versionName;
