Android的无法连接到摄像机服务 [英] Android Fail to connect to camera service

问题描述

在上摄像头的用户点击，打开它几秒钟后下一屏幕，它抛出无法连接到摄像机服务

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

和它说不能连接到相机

这是我的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);  
        }
} 

这是我的布局：

      <?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>

这是我的Andr​​oidManifest.xml文件

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>

我该按照这个链接<一做href="http://mobile.tutsplus.com/tutorials/android/android-sdk-quick-tip-launching-the-camera/">http://mobile.tutsplus.com/tutorials/android/android-sdk-quick-tip-launching-the-camera/

请帮我什么是issue.My应用程序包含标签的ActivityGroup。

Please help me what is an issue.My application contain Tab ActivityGroup.

在此先感谢。

下面是我的申请code - 希望它可以帮助：

Here's my application code -- hope it helps:

    String alert="";
    @Override

        img_logo = (ImageView) findViewById(R.id.camera_image);
        cancel = (Button) findViewById(R.id.camera_taken);
        upload = (Button) findViewById(R.id.camerabtnupload);

        if(image1.length()<= 0)
        startCameraActivity();

        upload.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                finish();
                if(image1.length() > 0){

                image1="";
                }
        });


    }


    public void LoardServer() {
    // this is use for upload image or save image   

    }


    private Handler handler = new Handler(){
        public void handleMessage(android.os.Message msg) {
            pd.dismiss();

                Log.d("hello","alert"+alert);

        Uri outputFileUri = Uri.fromFile(file);
        Intent intent = new Intent (android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        startActivityForResult(intent, 0);

        }
        @Override

        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(new FileInputStream( selectedImagePath), null, o);
        final int REQUIRED_SIZE = 70;
        int width_tmp = o.outWidth, height_tmp = o.outHeight;
        int scale = 1;
        while (true) {
        if (width_tmp / 2 < REQUIRED_SIZE
        || height_tmp / 2 < REQUIRED_SIZE)
        break;
        width_tmp /= 2;
        height_tmp /= 2;
        scale++;
        }
        // decode with inSampleSize

        } catch (FileNotFoundException e) {
        }
        return null;
        }
        public boolean onKeyDown(int keyCode, KeyEvent event) {
            if(keyCode==KeyEvent.KEYCODE_BACK)
            {
                finish();
            }
            return super.onKeyDown(keyCode, event);
        }

}

使用该camera.xml

 <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:background="#FFFFFF" android:layout_height="fill_parent" android:layout_width="fill_parent">
        <RelativeLayout android:id="@+id/relativeLayout1"
            android:layout_width="fill_parent"
            android:background="@drawable/bottoombg" android:layout_height="wrap_content">
            <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true"
                android:layout_centerHorizontal="true" android:textColor="#FBB917"
                android:textStyle="bold" android:textSize="20dip" android:id="@+id/txtCabNametitle" android:text="Camera"></TextView>
            <Button android:layout_alignParentRight="true" android:layout_centerVertical="true"
                android:background="@drawable/filter_btn1"
                android:layout_marginRight="5dip"
                android:layout_height="30dip" android:textColor="#FFFFFF" android:text="Upload" android:layout_width="70dip" android:id="@+id/camerabtnupload"></Button>
            <Button android:layout_centerVertical="true" android:background="@drawable/btn_press_effect" android:layout_height="30dip" android:textColor="#FFFFFF" android:paddingLeft="10dip" android:id="@+id/camera_taken" android:text="Cancel" android:layout_width="70dip"></Button>
        </RelativeLayout>
        <ImageView android:id="@+id/camera_image" android:layout_centerVertical="true" android:layout_centerHorizontal="true" android:layout_height="200dip" android:layout_width="200dip"></ImageView>
    </RelativeLayout>

AndroidManifest.xml中

AndroidManifest.xml

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