Question

I am making a application which relies on a class which uses a BroadCastReceiver so that I can catch when a application is installed and uninstalled. The intent is received just fine, and the code in onReceive executes as it should. Hoever, the problem I am having is that I get a a error message when I try to instantiate a new PackageManger. The error is: “Cannot instantiate the type PackageManager”.
I’ve pretty much tried all variations, but I just can’t get it to work.

my code:

package com.my.package;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.util.Log;

public class PackageReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Uri datauri         = intent.getData(); 
        String uri          = datauri.toString();
        PackageManager pm   = new PackageManager();
        //pm.getApplicationInfo(uri);   //broken
        test(datauri);                  //works fine
    }//end method

    public void test(Uri uri){
        Log.d("test", "data: "+uri);
    }//end method
}// end class

Answer 1

use

PackageManager pm= context.getPackageManager(); 
List<ApplicationInfo> applicationInfos = pm.getInstalledApplications(0);
....

instead of

PackageManager pm   = new PackageManager();
