Enable Hardware Acceleration for Android 3.0 or later devices

Android 3.0 (Honeycomb) introduced Hardware Acceleration. To enable Hardware Acceleration for your app, edit AndroidManifest.xml to insert the attribute android:hardwareAccelerated="true" in <application /> tag.

To check if any view/canvas is hardware accelerated, simple call:
- View.isHardwareAccelerated(), or
- Canvas.isHardwareAccelerated()

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.androidhardwareacceleration"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" 
        android:hardwareAccelerated="true">
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:text="Touch the big icon to check isHardwareAccelerated"/>

</RelativeLayout>

package com.example.androidhardwareacceleration;

        imageView = (ImageView)findViewById(R.id.iv);
        hw = (TextView)findViewById(R.id.hw);
        
        imageView.setImageResource(R.drawable.ic_launcher);

        imageView.setOnClickListener(new OnClickListener(){

   @Override
   public void onClick(View arg0) {
    boolean isHWAccelerated = imageView.isHardwareAccelerated();
          hw.setText("isHardwareAccelerated: " + String.valueOf(isHWAccelerated));
    
   }});
