Add these things in your android.manifest:

//Camera
    <uses-permission android:name="android.permission.CAMERA" />

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

//for sdcard

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
