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

Question

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

Answer 1

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);
}

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.

Answer 2

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

Java

public String getAppLable(Context context) {
    ApplicationInfo applicationInfo = null;
    try {
        applicationInfo = context.packageManager.getApplicationInfo(context.getPackageManager().getApplicationInfo().packageName, 0);
    } catch (final NameNotFoundException e) {
        Log.d("TAG", "The package with the given name cannot be found on the system.");
    }
    return (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);

UPDATE

Kotlin

fun getAppLable(context: Context): String? {
    var applicationInfo: ApplicationInfo? = null
    try {
        applicationInfo = context.packageManager.getApplicationInfo(context.applicationInfo.packageName, 0)
    } catch (e: NameNotFoundException) {
        Log.d("TAG", "The package with the given name cannot be found on the system.")
    }
    return (if (applicationInfo != null) packageManager.getApplicationLabel(applicationInfo) else "Unknown")
}

Answer 3

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()

Answer 4

From any Context use:

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

Answer 5

In Kotlin its simple:

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

Answer 6

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)
        }

Answer 7

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

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

Answer 8

You can use this

JAVA

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

Answer 9

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
  }
}

Answer 10

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.

Answer 11

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

Answer 12

The source comment added to NonLocalizedLabel directs us now to:

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

Answer 13

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
}

Answer 14

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.

Answer 15

If "don't have access" means you don't get the expected value... Try This:

String appName = getString(R.string.app_name);
