[android-developers] IllegalStateException when calling Preference.setDependency()

[flix]

Hello,

I'm trying to create a PreferenceScreen with a CheckBoxPreference
which depends on an other CheckBoxPreference using the setDependency()
method, as shown in the code below.

While calling the setDependency() method, I get the following
Exception:
java.lang.IllegalStateException: Dependency "preferenceKey1" not found
for preference "preferenceKey2" (title: "chbPref2"
     at android.preference.Preference.registerDependency
(Preference.java:1007)
     at android.preference.Preference.setDependency(Preference.java:
1124)
     at test.preferences.TestPreferencesActivity.createPreferenceScreen
(TestPreferencesActivity.java:28)
     at test.preferences.TestPreferencesActivity.onCreate
(TestPreferencesActivity.java:13)
     at android.app.Instrumentation.callActivityOnCreate
(Instrumentation.java:1123)
     at android.app.ActivityThread.performLaunchActivity
(ActivityThread.java:2231)
     ... 11 more

I have no idea what's wrong with this code. Without the setDependency
() call, the PreferenceScreen works well.

package test.preferences;

import android.os.Bundle;
import android.preference.CheckBoxPreference;
import android.preference.PreferenceActivity;
import android.preference.PreferenceManager;
import android.preference.PreferenceScreen;

public class TestPreferencesActivity extends PreferenceActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setPreferenceScreen(this.createPreferenceScreen());
    }

    private PreferenceScreen createPreferenceScreen() {
        PreferenceManager preferenceManager = this.getPreferenceManager
();
        PreferenceScreen preferenceScreen =
preferenceManager.createPreferenceScreen(this);

        CheckBoxPreference chbPref1 = new CheckBoxPreference(this);
        chbPref1.setTitle("chbPref1");
        chbPref1.setKey("preferenceKey1");
        preferenceScreen.addPreference(chbPref1);

        CheckBoxPreference chbPref2 = new CheckBoxPreference(this);
        chbPref2.setTitle("chbPref2");
        chbPref2.setKey("preferenceKey2");
        chbPref2.setDependency(chbPref1.getKey());
        preferenceScreen.addPreference(chbPref2);

        return preferenceScreen;
    }
}
