Media recorder and camera device

 I am trying to make use of the setCamera method with the mediareorder.
I have created and opened a new camera device however every reference
to it via setcamera results in an error about trying to access a
locked camera device.

There are no other open camera devices to the best of my knowledge.

Any ideas would be appreciated

1. Secure data storage (rooted phones)

Hello everyone,

Let's say there are hard security requirements that must include the
possibility of rooting a phone. So when a phone gets lost, the
sensitive data on it should still be as secure as possible even if the
phone is rooted.

Any hints and ideas on this?

The first thought was that one could generate a key based on some
device/user ID, but this information is available to all applications.
So given some reverse engineering and effort, this can be cracked too.

I am not exactly a security expert, but maybe there are some around
here in this group.

Thanks for all comments!

Regards,
Markus

2. StackOverflowError on a compound view

Hi,

I'm trying to reproduce the contact list component (I can't find it to
inlude it in my app). So I did a compound view like this for each
phone item: phone_list_item.xml :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01"
        android:layout_width="fill_parent"
android:layout_height="fill_parent"
        xmlns:android="http://schemas.android.com/apk/res/android">

        <Button android:id="@+id/phone_list_item_button_type"
                android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
        <EditText android:id="@+id/phone_list_item_value"
                android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
        <ImageButton android:src="@android:drawable/ic_delete"
                android:id="@+id/phone_list_item_button_remove"
android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>

</LinearLayout>

with a corresponding initialisation
public class PhoneListItem extends LinearLayout {
        protected Resources resources;
        protected Button type;
        protected EditText value;
        protected ImageButton removeButton;
        protected Phone phone;

        public PhoneListItem(Context context) {
                super(context);
                resources = getResources();
                LayoutInflater inflater = (LayoutInflater) getContext
().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                inflater.inflate(R.layout.phone_list_item, this, true);
                type = (Button) findViewById(R.id.phone_list_item_button_type);
                value = (EditText) findViewById(R.id.phone_list_item_value);
                removeButton = (ImageButton) findViewById
(R.id.phone_list_item_button_remove);
                removeButton.setImageResource(android.R.drawable.btn_minus);
        }

        public PhoneListItem(Context context, Phone phone) {
                this(context);
                setPhone(phone);
        }

        public Phone getPhone() {
                phone.setNumber(value.getText().toString());
                return phone;
        }

        public void setPhone(Phone phone) {
                this.phone = phone;
                type.setText(resources.getString(phone.getType()));
                value.setText(phone.getNumber());
        }

}


then a parent compound view to handle the list: phone_list.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/phone_list_main_layout"
        android:layout_width="fill_parent"
android:layout_height="fill_parent"
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical">

        <LinearLayout android:id="@+id/phone_list_cmds"
                android:layout_width="wrap_content"
android:layout_height="wrap_content">
                <TextView android:text="@string/phone_list_label" 
android:id="@+id/
phone_list_label"
                        android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
                <ImageButton android:id="@+id/phone_list_button_add"
android:src="@android:drawable/btn_plus"
                        android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_gravity="right"></
ImageButton>
        </LinearLayout>
        <TableLayout android:id="@+id/phone_list_items"
                android:layout_width="fill_parent"
android:layout_height="fill_parent"></TableLayout>
</LinearLayout>

with its class:
public class PhoneListView extends LinearLayout {

        protected TableLayout phoneListTable;
        protected ImageButton addPhoneButton;
        protected ArrayAdapter<Phone> adapter;
        protected ArrayList<Phone> phones = new ArrayList<Phone>();

        public PhoneListView(Context context, AttributeSet attributeSet) {
                super(context, attributeSet);
                LayoutInflater inflater = (LayoutInflater) getContext
().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                inflater.inflate(R.layout.phone_list, this, true);
                phoneListTable = (TableLayout) 
findViewById(R.id.phone_list_items);
                addPhoneButton = (ImageButton) findViewById
(R.id.phone_list_button_add);
                // addPhoneButton.setImageResource(android.R.drawable.btn_plus);
        }

        public ArrayList<Phone> getPhones() {
                return phones;
        }

        public void setPhones(ArrayList<Phone> phones) {
                this.phones = phones;
                phoneListTable.removeAllViews();
                for (Phone phone : phones) {
                        Context context = getContext();
                        TableRow row = new TableRow(context);
                        row.addView(new PhoneListItem(context, phone));
                        // EditText editText = new EditText(context);
                        // editText.setText(phone.getNumber());
                        // row.addView(editText);
                        phoneListTable.addView(row);
                }
                phoneListTable.postInvalidate();
        }

}


When I attempt to display it, it displays for a while then I have the
following exception:
I just included the view to a linear layout:
                                        
<eu.nextstreet.android.compound.PhoneListView android:id="@+id/
view_entity_phones" android:layout_width="fill_parent"
android:layout_height="wrap_content"/>

and add it phones like this:
                blcPhones = (PhoneListView) 
findViewById(R.id.view_entity_phones);
                blcPhones.setPhones(geoLocationFlag.getPhones());

As I said the page displays correctly then throws this exception. Any
one has an idea?
Best Regards,
Zied Hamdi
