Startactivity() Not Working From Inner Class That Extends Listactivity

Title basically says it all. The below code doesn't throw any errors, it just doesn't start the new activity. Code below. I have tried modifying startActivity(new Intent(mCtx, Ne

Solution 1:

Possible cause 1

The activity has not been declared.

You have to add the activity to your AndroidManifest.xml

You should add this to your <application> tag in your AndroidManifest.xml:

<activityandroid:name="package.name.NewActivity"><!-- Add an intent filter here if you wish --></activity>

Possible cause 2

The onChange method doesn't actually run.

Please use the code below to verify that the onChange method actually gets called:

publicclassMyListActivityextendsListActivity {
    MyContentObserver mContentObserver;

    @OverridepublicvoidonCreate(Bundle onSavedInstance) {
        super.onCreate(onSavedInstance);
        setContentView(R.layout.calls_list);

        mContentObserver = newMyContentObserver();

        this.getApplicationContext().getContentResolver().registerContentObserver(CallLog.Calls.CONTENT_URI, true, mContentObserver);
    }

    privateclassMyContentObserverextendsContentObserver {
        publicMyContentObserver() {
            super(null);
        }

        @OverridepublicvoidonChange(boolean selfChange) {
            super.onChange(selfChange);
            Log.d("MyListActivity.MyContentObserver", "onChange");
            startActivity(newIntent(MyListActivity.this, NewActivity.class));
        }
    }   
}

You could also try launching the activity from onCreate to make sure it can be launched.
