My android imageView is black no matter what -

i try display imageview app on (hopefully) defined view (xml)

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activityshowlayout" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#73c310" android:orientation="vertical" tools:context=".showactivity" >  <imageview     android:id="@+id/mainimage"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_above="@+id/moodbutton"     android:layout_alignparentleft="true"     android:layout_alignparentright="true"     android:layout_alignparenttop="true"     android:layout_margin="12dp"     android:background="#000"     android:src="@drawable/gs_04_pic" />  <!-- ... --> 

and after in oncreate method on activity

    @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      setcontentview(r.layout.activity_show);      /* ... blabla bla ... */      imageview imageview = (imageview) findviewbyid(r.id.mainimage);      bitmap bitmap = bitmapfactory.decodebytearray(cream.getmedia(), 0, cream.getmedia().length);     drawable draw = new bitmapdrawable(getresources(), bitmap);     imageview.setimagedrawable(draw);     imageview.invalidate(); } 

with cream.getmedia() returning valid byte[] (from database) can log giving me:

07-18 17:41:16.812: i/app(9883): byte[] is: [b@414af0b0

but @ end imageview black (no image on it) if don't run oncreate code displays resource set in xml (on black background set in xml too)

what wrong?

i run problem, in case problem came config in:

bluid.gradle

shrinkresources true 

it deleted files because didn't have static reference resources. (images in case)

so found article "keeping resources" in link resource shrinking

in resumen says: should make file in path "/res/raw/keep.xml"

<?xml version="1.0" encoding="utf-8"?> <resources xmlns:tools="http://schemas.android.com/tools"   tools:keep="@layout/l_used*_c,@layout/l_used_a,@layout/l_used_b*"/>
