[android] 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

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

See the answer to a very similar question here.

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)");

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
  }
}

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);

From any Context use:

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

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.

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)
        }

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

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

The source comment added to NonLocalizedLabel directs us now to:

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

In Kotlin its simple:

val appLabel = context.applicationInfo.nonLocalizedLabel

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()

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>
