Have found already some people asking the same, but the solutions didn't work for me.

I see no animation.

Calling it 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 anim 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>

Using min. API 7:

manifest:

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

API 7 is also in my project.properties file:

target=android-7

What am I doing wrong?

P.D. Removing the lines with the interpolator doesn't change anything.

Already seen / tried:

overridePendingTransition doesn't work

overridePendingTransition does not work when flag_activity_reorder_to_front is used
