Question

How to get the application icon that i got from the result into arraylist?

If i use
attrs.icon("Package Name", pkg.applicationInfo.loadIcon(getPackageManager()));

it show this error
The method icon(String, Drawable) is undefined for the type Map

if i use
attrs.put("Package Name", pkg.applicationInfo.loadIcon(getPackageManager()));

it show this error
The method put(String, String) in the type Map is not applicable for the arguments (String, Drawable)

i have tried

Drawable icon;

attrs.icon("Package Name", pkg.applicationInfo.loadIcon(getPackageManager()));

Drawable Icon = pm.getApplicationIcon(pkg.applicationInfo);

all giving error on eclipse

Here’s the code

protected void onPostExecute(List < PackageInfo > result) {

    // Here you will have all the setAdapter related code
    List < PackageInfo > adPackages = result;
    PackageManager pm = getPackageManager();

    List < Map < String, String >> data = new ArrayList < Map < String, String >> (
    adPackages.size());

    for (PackageInfo pkg: adPackages) {
        Map < String, String > attrs = new HashMap < String, String > ();

        attrs.put("App Name", pm.getApplicationLabel(pkg.applicationInfo).toString());
        attrs.put("Package Name", pkg.packageName);
        //Drawable icon;
        //attrs.icon("Package Name", pkg.applicationInfo.loadIcon(getPackageManager()));
        // Drawable Icon = pm.getApplicationIcon(pkg.applicationInfo);
        data.add(attrs);

    }

    String[] from = new String[] {
        "App Name", "Package Name"
    };
    int[] to = new int[] {
        R.id.text1, R.id.text2
    };
    SimpleAdapter adapter = new SimpleAdapter(
    AppsInspectorActivity.this, data, R.layout.two_line_list_item, from, to);

    ListView mList = (ListView) findViewById(R.id.l_list);

    mList.setAdapter(adapter);
    mPackages = adPackages;

}
}

attrs is a Map so it doesn’t have a method called “icon”. You need to just do attrs.put("icon",pkg.applicationInfo.icon+"");
the +"" is there because pkg.applicationInfo.icon is an integer so you need to convert it to a String before you can put it into a map parameterized with
