Trying to get the version number but application crashes

I want to get the version number of my application but the application crashes upon load when I try it.

int currentVersionCode;
try {
    currentVersionCode = this.getPackageManager().getPackageInfo(
            this.getApplicationInfo().packageName, 0).versionCode;
    Toast.makeText(this, currentVersionCode, Toast.LENGTH_SHORT).show();
} catch (NameNotFoundException e) {
    return;
}

LogCat:

If you want the versionName, then:

   String currentVersionName;
    try {
        currentVersionName = this.getPackageManager().getPackageInfo(
                this.getApplicationInfo().packageName, 0).versionName;
        Toast.makeText(this, currentVersionName, Toast.LENGTH_SHORT).show();
    } catch (NameNotFoundException e) {
        e.printStackTrace();
    }

is more appropriate, that would work if you had

  android:versionCode="1"
  android:versionName="Mickey Mouse"

It would show "Mickey Mouse". The answer you accepted would show "1"

float currentVersionCode;
try {
    currentVersionCode = this.getPackageManager().getPackageInfo(
            this.getApplicationInfo().packageName, 0).versionCode;
    Toast.makeText(this, ""+currentVersionCode, Toast.LENGTH_SHORT).show();
} catch (NameNotFoundException e) {
    return;
}

Try this...a minor change

use the below for your reference...

String versionName = context.getPackageManager().getPackageInfo(context.getPackageName(), 0 ).versionName;

The problem is that you are passing the version to Toast.makeText as an int. If you pass an int to makeText it assumes it's a String resource ID. This is why you are getting a string resource not found error.

Convert the version code to a String, before passing it to makeText.
