android - Unable to start activity componentinfo (error en setContentView) -

i know highlight topic, can't find mistake...

i have in .mainactivity:

public class mainactivity extends activity{  ...      public void abrirappmovimiento(view view) {         intent mov = new intent(this, movimiento.class);         startactivity(mov);     }  ...  } 

this androidmanifest.xml:

    <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.emiliomorillanieto.practica3" >      <application         android:allowbackup="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >          <activity             android:name=".mainactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                 <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>          <activity             android:name=".movimiento"             android:parentactivityname=".mainactivity" >             <meta-data                 android:name="android.support.parent_activity"                 android:value=".mainactivity" />         </activity>     </application>  </manifest> 

and class .movimiento:

public class movimiento extends activity implements sensoreventlistener {      @override      protected void oncreate(bundle savedinstancestate) {          super.oncreate(savedinstancestate);          setcontentview(r.layout.activity_movimiento);       }  } 

i have being debugging app, , when app enters .movimiento, savedinstancestate null, error comes while trying "setcontentview".

why can possible, if have activity_movimiento.xml defined in androidmanifest.xml?

my activity_movimiento.xml relativelayout buttons play sound when it's touched. nothing special.

edit: activity_movimiento.xml:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@color/gris_oscuro"     android:orientation="vertical">      <button         android:id="@+id/volver"         style="?android:attr/buttonstylesmall"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparentbottom="true"         android:layout_alignparentleft="true"         android:layout_alignparentstart="true"         android:onclick="volveratras"         android:text="volver" />      <textview         android:id="@+id/tv_resultado"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparentbottom="true"         android:layout_centerhorizontal="true"         android:layout_marginbottom="56dp"         android:text="@string/resultado"         android:textappearance="?android:attr/textappearancemedium" />      <imageview         android:id="@+id/image_chew"         android:layout_width="150px"         android:layout_height="150px"         android:layout_alignparenttop="true"         android:layout_centerhorizontal="true"         android:layout_margintop="63dp"         android:src="@raw/chew_picture" />      <imageview         android:id="@+id/image_laser"         android:layout_width="150px"         android:layout_height="150px"         android:layout_alignparentend="true"         android:layout_alignparentright="true"         android:layout_centervertical="true"         android:src="@raw/laser_picture" />      <imageview         android:id="@+id/image_darth"         android:layout_width="150px"         android:layout_height="150px"         android:layout_alignparentleft="true"         android:layout_alignparentstart="true"         android:layout_aligntop="@+id/image_laser"         android:src="@raw/darth_picture" />      <imageview         android:id="@+id/image_luke"         android:layout_width="150px"         android:layout_height="150px"         android:layout_above="@+id/tv_resultado"          android:layout_alignleft="@+id/image_chew"         android:layout_alignstart="@+id/image_chew"         android:src="@raw/luke_picture" />  </relativelayout> 

and error:

the inflate exception not problem here , here comes issue in layout out of memory exception.

a common issue out of memory exception when trying inflate imageview loading drawable resource. if 1 of resources has high pixel resolution take lot of memory causing inflate exception.

so verify pixel resolution in drawables images minimum necessary layout.

checkout out of memory issue explaination.

hope helps.
