How to get the build/version number of your Android application?
I need to figure out how to get or make a build number for my Android application. I need the build number to display in the UI.
Do I have to do something with AndroidManifest.xml ?
Use:
try {
PackageInfo pInfo = this.getPackageManager().getPackageInfo(getPackageName(), 0);
String version = pInfo.versionName;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
And you can get the version code by using this
int verCode = pInfo.versionCode;
If you're using the Gradle plugin/Android Studio, as of version 0.7.0, version code and version name are available statically in BuildConfig . Make sure you import your app's package, and not another BuildConfig :
import com.yourpackage.BuildConfig;
...
int versionCode = BuildConfig.VERSION_CODE;
String versionName = BuildConfig.VERSION_NAME;
No Context object needed!
Also make sure to specify them in your build.gradle file instead of the AndroidManifest.xml .
defaultConfig {
versionCode 1
versionName "1.0"
}
如果您只想要版本名称，稍微缩短版本。
String versionName = context.getPackageManager()
.getPackageInfo(context.getPackageName(), 0).versionName;
