Android 取得版本資訊

使用 PackageInfo 取得版本資訊

PackageInfo pInfo = null;
try {
    pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
} catch (Exception ex) {

}

int versionCode = pInfo.versionCode;
String versionName = pInfo.versionName;

如果有掛載 Gradle plugin 或是 使用 Android Studio 0.7.0 以上，就可以用 BuildConfig 取得版本資訊

int versionCode = BuildConfig.VERSION_CODE;
String versionName = BuildConfig.VERSION_NAME;
