My app have system priveleges. It will be inside firmware, now it's located at /system/app
I was able to install apps silently with this post

example app that works

But I still can't uninstall apps the same way. I tried to use reflecion like as in the installation example.

Code: Select all

public ApplicationManager(Context context) throws SecurityException, NoSuchMethodException {

    observer = new PackageInstallObserver();
    pm = context.getPackageManager();

    Class<?>[] types = new Class[] {Uri.class, IPackageInstallObserver.class, int.class, String.class};
    Class<?>[] uninstalltypes = new Class[] {String.class, IPackageInstallObserver.class, int.class};
    method = pm.getClass().getMethod("installPackage", types);
    uninstallmethod = pm.getClass().getMethod("deletePackage", uninstalltypes);
}


public void uninstallPackage(String packagename) throws IllegalArgumentException, IllegalAccessException, InvocationTargetException {
        uninstallmethod.invoke(pm, new Object[] {packagename, observer, 0});
    }
    public void installPackage(Uri apkFile) throws IllegalArgumentException, IllegalAccessException, InvocationTargetException {
        method.invoke(pm, new Object[] {apkFile, observer, INSTALL_REPLACE_EXISTING, null});
    }

I have added uninstallPackage method and edited ApplicationManager method. Still cant get this working.
