Android - How to get application name? (Not package name)

In my manifest I have:

  <application
    android:name=".MyApp"
    android:icon="@drawable/ic_launcher_icon"
    android:label="@string/app_name"
    android:debuggable="true">

How do I get the label element?

Note: My code is running inside of someone else's, so I don't have access to @string/app_name

There's an easier way than the other answers that doesn't require you to name the resource explicitly or worry about exceptions with package names. It also works if you have used a string directly instead of a resource.

Just do:

public static String getApplicationName(Context context) {
    ApplicationInfo applicationInfo = context.getApplicationInfo();
    int stringId = applicationInfo.labelRes;
    return stringId == 0 ? applicationInfo.nonLocalizedLabel.toString() : context.getString(stringId);
}

Hope this helps.

Edit

In light of the comment from Snicolas, I've modified the above so that it doesn't try to resolve the id if it is 0. Instead it uses, nonLocalizedLabel as a backoff. No need for wrapping in try/catch.

If not mentioned in the strings.xml/hardcoded in AndroidManifest.xml for whatever reason like android:label="MyApp"

public String getAppLable(Context context) {
    PackageManager packageManager = context.getPackageManager();
    ApplicationInfo applicationInfo = null;
    try {
        applicationInfo = packageManager.getApplicationInfo(context.getApplicationInfo().packageName, 0);
    } catch (final NameNotFoundException e) {
    }
    return (String) (applicationInfo != null ? packageManager.getApplicationLabel(applicationInfo) : "Unknown");
}

Or if you know the String resource ID then you can directly get it via

getString(R.string.appNameID);

Java

public static String getApplicationName(Context context) {
    return context.getApplicationInfo().loadLabel(context.getPackageManager()).toString();
}

Kotlin (as extension)

fun Context.getAppName(): String = applicationInfo.loadLabel(packageManager).toString()

From any Context use:

getApplicationInfo().loadLabel(getPackageManager()).toString();

If you know Package name then Use following snippet

ApplicationInfo ai;
try {
    ai = pm.getApplicationInfo(packageName, 0);
} catch (final NameNotFoundException e) {
    ai = null;
}
final String applicationName = (String) (ai != null ? pm.getApplicationLabel(ai) : "(unknown)");

In Kotlin, use the following codes to get Application Name:

        // Get App Name
        var appName: String = ""
        val applicationInfo = this.getApplicationInfo()
        val stringId = applicationInfo.labelRes
        if (stringId == 0) {
            appName = applicationInfo.nonLocalizedLabel.toString()
        }
        else {
            appName = this.getString(stringId)
        }

In Kotlin its simple:

val appLabel = context.applicationInfo.nonLocalizedLabel.toString()

If you need only the application name, not the package name, then just write this code.

 String app_name = packageInfo.applicationInfo.loadLabel(getPackageManager()).toString();
       

Get Appliction Name Using RunningAppProcessInfo as:

ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
List l = am.getRunningAppProcesses();
Iterator i = l.iterator();
PackageManager pm = this.getPackageManager();
while(i.hasNext()) {
  ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next());
  try {
    CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
    Log.w("LABEL", c.toString());
  }catch(Exception e) {
    //Name Not FOund Exception
  }
}

By default you have a string resource called "app_name" generated by AndroidStudio. Why not simply use that? Or any other string resource created for this purpose. Much easier than calling several internal methods to come up with a value you have to set yourself in the first place.

Okay guys another sleek option is

Application.Context.ApplicationInfo.NonLocalizedLabel

verified for hard coded android label on application element.

<application android:label="Big App"></application>

Reference: http://developer.android.com/reference/android/content/pm/PackageItemInfo.html#nonLocalizedLabel

The source comment added to NonLocalizedLabel directs us now to:

return context.getPackageManager().getApplicationLabelFormatted(context.getApplicationInfo());

You can use this

> JAVA

ApplicationInfo appInfo = getApplicationContext().getApplicationInfo();
String applicationLabel = getApplicationContext().getPackageManager().getApplicationLabel(appInfo).toString();

Kotlin

> A simple function to get the name of the application in kotlin

fun getApplicationName() : String{
    var applicationName = ""
    try {
        val applicationInfo = application.applicationInfo
        val stringId = applicationInfo.labelRes
        if (stringId == 0) {
            applicationName = applicationInfo.nonLocalizedLabel.toString()
        }
        else {
            applicationName = application.getString(stringId)
        }
    } catch (e: Exception) {
        e.printStackTrace()
    }
    return applicationName
}

Have you tried using the PackageManager#getActivityInfo() method? There will be a field that should contain the name of the application.
