Question

in my application I call

startActivityForResult( new Intent(this, ShowPreferencesActivity.class), <some code>);

the activity is declared as :

package ca.qc.webalterpraxis.cinedroid.activity.preference;

public class ShowPreferencesActivity extends PreferenceActivity { ...}

and in my manifest I got :

<activty android:name=".activity.preference.ShowPreferencesActivity" android:label="@string/set_preferences">

But I receive an exception when I try to start the activity (in the first line of code of this question) :

E/AndroidRuntime(1830): android.content.ActivityNotFoundException: Unable to find explicit activity class {ca.qc.webalterpraxis.cinedroid/ca.qc.webalterpraxis.cinedroid.activity.preference.ShowPreferencesActivity}; have you declared this activity in your AndroidManifest.xml?

I tried everything I could :

• replacing, in the manifest, the name of the class with the fully qualified name of the class
• setting the intent class name using setClassName
• providing a default filter for the activity

I relaunched eclipse around 10 times, rebooted my computer, erased the application from the device, resintalled, etc…

I don’t have any idea of what’s happening. And the worse is that it was working before, but not anymore after I renamed the class. Something strange : even if I rename the class now, the AndroidManifest won’t update in eclipse, I have to update it by hand..but it still works for other classes…

Also, please note that I have a test application, apart of the under test app, and the test app can’t find the activity to instrument it, neither.

Oh, and last but not least, I am 100 % sure that the ShowPreferencesActivity is in the resulting dex file, I dexdumped it to check.

Thanks in advance for your time.

Thanks all, I found my problem : the tag in the manifest was

<activty

and not

<activity

But why does eclipse allow that ???!!!
