Question

When the user click on Camera, it open next screen after few seconds it throws Fail to connect to camera service

and it say cannot connect to camera

This is my code:

   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    View viewLoad = LayoutInflater.from(CameraActivity.this).inflate(R.layout.camera, null);
    setContentView(viewLoad);

    Bundle bundle = this.getIntent().getExtras();
    seletctedRetailer = bundle.getString("RetailerName");
    retailerCode = bundle.getString("RetailerCode");

    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    Bundle b = new Bundle();
    b.putString("Activity", "RetailerOrderSActivity");
    b.putString("RetailerName", seletctedRetailer);
    b.putString("RetailerCode", retailerCode);

    cameraIntent.putExtras(b);
    getParent().getParent().setTitle("Image Capture");
    startActivityForResult(cameraIntent,CAMERA_PIC_REQUEST);  

    vale +=1;

    Button imgMCancel =(Button)findViewById(R.id.imgMCancel);
    imgMCancel.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            Intent i = new Intent(getBaseContext(), CameraMainActivity.class);
            Bundle bundle = new Bundle(); 
            bundle.putString("Activity", "CameraMainActivity");
            bundle.putString("RetailerName", seletctedRetailer);
            bundle.putString("RetailerCode", retailerCode);
            i.putExtras(bundle);
            View vi = SalesActivityGroup.group.getLocalActivityManager().startActivity("CameraMainActivity", i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
            SalesActivityGroup.group.replaceView(vi);
        }
    });
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == CAMERA_PIC_REQUEST) {
            System.out.println("====YES======");
             Bitmap thumbnail = (Bitmap) data.getExtras().get("data");  
                ImageView image = (ImageView) findViewById(R.id.imageView1);  
                image.setImageBitmap(thumbnail);  
        }
} 

This is my layout :

      <?xml version="1.0" encoding="utf-8"?>

    <LinearLayout android:id="@+id/header"
                android:layout_height="wrap_content"
                android:layout_marginBottom="10dp"
                android:layout_marginTop="75dp"
                android:layout_width="fill_parent">


        <Button android:layout_width="wrap_content" 
                android:text="Cancel" 
                android:textColor="#FFFFFF"
                android:background="@drawable/btn_red"
                android:layout_height="wrap_content" 
                android:layout_marginLeft="5dp"
                android:layout_marginRight="150dp"
                android:id="@+id/imgMCancel" 
                >
       </Button>

       <Button android:layout_width="wrap_content"
                android:layout_height="wrap_content" 
                android:id="@+id/buttonClick"
                android:text="Make Photo" 
                android:textColor="#FFFFFF"
                android:background="@drawable/btn_red"
                android:layout_gravity="center">
        </Button>


    </LinearLayout>

This is my AndroidManifest.xml file

     <activity android:name=".sales.CameraActivity"              android:screenOrientation="landscape"  android:configChanges="orientation|keyboardHidden"  android:clearTaskOnLaunch="false">
        <intent-filter>
            <action android:name="android.media.action.IMAGE_CAPTURE" />
            <category android:name="android.intent.category.DEFAULT" />
      </intent-filter>
  </activity>

Here’s my application code — hope it helps:

public class CameraActivity extends Activity {

    int count = 0;
    static String image1 = "";

Use this camera.xml
