Java: Need some way to shorten this code

Question

I have this piece of code that I would like to shorten...

    PackageManager p = context.getPackageManager();
    final List appinstall =          


        

Answer 1

If it's the same syntax as C# and the flags are set properly, you could do this:

PackageManager p = context.getPackageManager(); 
final List<PackageInfo> appinstall = 
    p.getInstalledPackages(PackageManager.GET_PERMISSIONS | 
                                      PackageManager.GET_PROVIDERS)

Answer 2

public void usegetPackageInfo(){
    // 
    final ListView lw = (ListView) findViewById(R.id.listView1);

    PackageManager p = lw.getContext().getPackageManager(); 
    final List<PackageInfo> appinstall = 
        p.getInstalledPackages(PackageManager.GET_PERMISSIONS | 
                                          PackageManager.GET_PROVIDERS);
    final TextView tw = (TextView) findViewById(R.id.textView1);
    Iterator it = appinstall.iterator();
    while (it.hasNext()) {
        PackageInfo rf = (PackageInfo) it.next();
        tw.append(rf.toString());

    }

}

Answer 3

check the android Documentation: for permissions: http://developer.android.com/guide/topics/manifest/uses-permission-element.html

for providers: http://developer.android.com/guide/topics/manifest/provider-element.html

Before that Completely study about manifest documentation
