[Programing Center]

Hi
i want to get the list of running applications. i want to use this code https://stackoverflow.com/questions...ist-of-running-applications/22503513#22503513
and i write this code

    Dim NativeMe As JavaObject
#if java
import anywheresoftware.b4a.BA;
import android.content.pm.PackageManager;
import java.util.List;
import android.content.pm.ApplicationInfo;
BA ba;
    public String getActiveApps() {
        PackageManager pm = ba.context.getPackageManager();
        List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
        String value = ""; // basic date stamp
        value += "---------------------------------\n";
        value += "Active Apps\n";
        value += "=================================\n";
        for (ApplicationInfo packageInfo : packages) {
            //system apps! get out
            if (!isSTOPPED(packageInfo) && !isSYSTEM(packageInfo)) {
                value += getApplicationLabel(packageInfo.packageName) + "\n" + packageInfo.packageName  + "\n-----------------------\n";
            }
        }
        return value;
    }

private boolean isSTOPPED(ApplicationInfo pkgInfo) {

    return ((pkgInfo.flags & ApplicationInfo.FLAG_STOPPED) != 0);
}

private boolean isSYSTEM(ApplicationInfo pkgInfo) {

    return ((pkgInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0);
}

public String getApplicationLabel(String packageName) {

    PackageManager        packageManager = ba.context.getPackageManager();
    List<ApplicationInfo> packages       = packageManager.getInstalledApplications(PackageManager.GET_META_DATA);
    String                label          = null;

    for (int i = 0; i < packages.size(); i++) {

        ApplicationInfo temp = packages.get(i);

        if (temp.packageName.equals(packageName))
            label = packageManager.getApplicationLabel(temp).toString();
    }

    return label;
}
  #End If
    NativeMe.InitializeContext
    dim list_running_aplication  as list = NativeMe.RunMethod("getActiveApps",Array As String(""))

and give me Errors

** Activity (main) Create, isFirst = true **
Error occurred on line: 79 (Main)

** Activity (main) Resume **

what should i do?
and Where should I change it to get the list of running applications? no log
it means i want to have dim list_running_aplication as list ?

As discussed in many threads: https://www.b4x.com/android/forum/pages/results/?query=getRunningTasks it will not work: https://developer.android.com/reference/android/app/ActivityManager#getRunningTasks(int)

It means it's impossible?
