I am having difficulty displaying the camera feed in an Activity that uses the VideoView view. I am simply trying to view my camera (later of which I hope to either record or take a photo) I don't want to use an intent, and I want the actual view to be in a box 50dp X 50dp. The code compiles and I see a blank activity with a black box that is 50X50 dps. The only problem is that it is now displaying the live feed of the camera. This is the code I have...The Manifest file
I made sure to include the proper permissions\[code\]<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.myview" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" /> <uses-permission android:name="android.permission.RECORD_VIDEO"/> <uses-permission android:name="android.permission.CAMERA"/> <uses-permission android:name="android.permission.RECORD_AUDIO"/> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <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>\[/code\]Next in my layout file I create a VideoView and set the attributes. (Am I setting all the correct attributes?)The Layout File\[code\]<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:custom="http://schemas.android.com/apk/res/com.example.myview" android:id="@+id/LinearLayout1" android:layout_width="match_parent" android:layout_height="match_parent" android
