Get WebView version number for lollipop?

Question

I have Lollipop, and see that we have a separate app for \"android system webview\". Is there any way to get its version number from my own app that uses a WebView instance?

Answer 1

UPDATE: Apparently this will not always accurately give the actual WebView client being used on the target device. As of Android 7.0 users can select preferred client (h/t @Greg Dan).

First, we get the package name from Google Play Store:

https://play.google.com/store/apps/details?id=com.google.android.webview

Then this

PackageManager pm = getPackageManager();
try {
    PackageInfo pi = pm.getPackageInfo("com.google.android.webview", 0);
    Log.d(TAG, "version name: " + pi.versionName);
    Log.d(TAG, "version code: " + pi.versionCode);
} catch (PackageManager.NameNotFoundException e) {
    Log.e(TAG, "Android System WebView is not found");
}

gives

D/WebViewDetails﹕ version name: 39 (1743759-arm)
D/WebViewDetails﹕ version code: 320201

Hope this helps.
