Getting error when trying to retrieve versionCode from android app

Question

anyone who knows what is going wrong? I am repeatedly getting this error when trying to retrieve the version code out of my manifest:

04-19 15:09:34.778: W/ResourceType(29293): No package identifier when getting value for           resource number 0x00000001

and this is the code I use to retrieve the versionCode out of my manifest file:

int currentVersion = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;

and ofcourse my manifest file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myapp.default"
android:versionCode="1"
android:versionName="1.0" >

I hope you guys can help me out.

my onCreate method:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Remove title bar
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    TLogFile.appendLog("i", "UPDATER", "Updaten");

    // setting some display
    setContentView(R.layout.frmupdate);
    TextView tv = new TextView(this);
    tv.setText("Loading...");

    // making sure the download directory exists
    checkAndCreateDirectory("/downloads");

    try {
        int currentVersion = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;
        Toast.makeText(this, currentVersion, Toast.LENGTH_LONG).show();
    } catch (NameNotFoundException n) {
        n.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }

    // executing the asynctask
    new DownloadFileAsync().execute(fileURL);
}

Looks like you are trying to put the currentVersion into a Toast. When you do so you need to convert it to a String or else it assumes you are refering to a String resource. Try something like this instead of what you have: Toast.makeText(ctx, ""+ currentVersion, Toast.LENGTH_SHORT).show() — FoamyGuy

As the logcat states, you're getting a NotFoundException for a resource when trying to call Toast.makeText(). While I can't see any code connected to Toast in the question description, I will try to make a guess. There are two overloaded makeText() methods in Toast:

makeText(Context context, int resId, int duration)

and

makeText(Context context, CharSequence text, int duration)

Probably you're passing your versionCode, which is an int, as the second parameter, and while you want the second version of makeText() to be called, what gets called is the first one, where the versionCode is treated as the resId. There is probably no resource with this id and the error proves it. So what you need to do is to pass String.valueOf(versionCode) as the second argument, then the Toast will display the value of the versionCode.

I am using the first one, with the 'int resID'

Leeeeeeelo Over a year ago

You should use the second as Egor mentioned it, using String.value ( versionCode )

@user, When using this version of method, you should pass a resource id of a string that's defined in XML. If you want to display an int, you should "cast" it to String as described above.

PackageInfo pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);

It seems you are using this vesionCode in any Toast. For Example If you want to show it in a textview tv

tv.setetext(versionCode);

so this is trigerring tv.setText(int resID);

But in your R.java there is no resource id with versionCode.

So to see the version code first convert it to String. then show it.
