TextureView with camera preview

Question

I would like to use TextureView to show camera preview in it. Finally i want to set opacity for camera preview, using TextureView. But i have problem:

Answer 1

You should set this in you manifest.xml.

android:hardwareAccelerated="true"

Where you declare this it's up to where you want to use your TextureView,you used it in your service.so you should declare this in your service declaration.

<service android:hardwareAccelerated="true"
 /> 

Answer 2

try using this...

<uses-feature
        android:name="android.hardware.camera"
        android:required="false"/>
    <uses-feature
        android:name="android.hardware.camera.autofocus"
        android:required="false"/>

<application
        android:name=".app.ExampleApp"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/AppTheme"
        android:hardwareAccelerated="true" >

This worked for me
