Detect my app's own android:versionCode at run time

Question

Is there a way for my app to know the android:versionCode from AndroidManifest.xml or do I have to create a separate constant in one of my classes?

Answer 1

I put this in my subclassed android.app.Application but you can use it anywhere you have a context. Just change getPackageManager() to context.getPackageManager().

public int getVersion() {     int v = 0;     try {         v = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;     } catch (NameNotFoundException e) {         // Huh? Really?     }     return v; } 

Answer 2

Yes, you can access this information via PackageManager.getPackageInfo

Also, see details about versioning in the documentation
