OverridePendingTransition not working

Found that some people ask the same thing, but the solutions did not work for me.

I do not see the animation.

The call this way:

Intent intent = new Intent(this, MyActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.fadein, R.anim.fadeout);

fadein.xml and fadeout.xml are in the animation folder:

fadein.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <alpha
        android:duration="1000"
        android:fromAlpha="0.0"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toAlpha="1.0" />
</set>

fadeout.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

  <alpha
      android:duration="1000"
      android:fromAlpha="1.0"
      android:interpolator="@android:anim/accelerate_interpolator"
      android:toAlpha="0.0" />

</set>

Use min. API 7:

manifest:

<uses-sdk android:minSdkVersion="7"/>

API 7 is also located in the project.properties file:

target=android-7

What am I doing wrong?

PD Deleting lines using the interpolator does not change anything.
