解决方案

 列表＆LT; ApplicationInfo＆GT;清单= packageManager.getInstalledApplications（PackageManager.GET_UNINSTALLED_PACKAGES）;
    对于（INT N = 0; N＆LT;则为list.size（）; N ++）{
        如果（（list.get（N）.flags＆安培; ApplicationInfo.FLAG_SYSTEM）== 1）
        {
            Log.d（TAG，安装的应用程序：+ list.get（N）.loadLabel（软件包管理系统）的ToString（））;
            Log.d（TAG，包名+ list.get（N）.packageName）;
            如果（list.get（N）.loadLabel（软件包管理系统）的ToString（）。equalsIgnoreCase（照相机））{
                defaultCameraPackage = list.get（N）.packageName;
                打破;
            }
        }
    }
 

我发现以下解决方案及其工作完美。

 意图takePictureIntent =新意图（MediaStore.ACTION_IM​​AGE_CAPTURE）;
takePictureIntent.setPackage（defaultCameraPackage）;
startActivityForResult（takePictureIntent，动作code）;
 

您可以通过在上述意图设置过滤包默认的摄像头。我已经通过安装两个应用测试了它的的线摄像机的和 纸相机的这两个应用都显示通过选择器，但过滤包以上$ ​​C $ C只能打开默认的摄像头。

How to open default camera in your application?

I don't want to open chooser for it (its client's requirement). I am using this intent android.media.action.IMAGE_CAPTURE and calling activity for result.

Everything is fine but apps like Line Camera, Paper Camera are appearing in chooser with default camera app, i don't want to show chooser for.

Your attentions will be highly appreciated.

解决方案

    List<ApplicationInfo> list = packageManager.getInstalledApplications(PackageManager.GET_UNINSTALLED_PACKAGES);
    for (int n=0;n<list.size();n++) {
        if((list.get(n).flags & ApplicationInfo.FLAG_SYSTEM)==1)
        {
            Log.d("TAG", "Installed Applications  : " + list.get(n).loadLabel(packageManager).toString());
            Log.d("TAG", "package name  : " + list.get(n).packageName);
            if(list.get(n).loadLabel(packageManager).toString().equalsIgnoreCase("Camera")) {
                defaultCameraPackage = list.get(n).packageName;
                break;
            }
        }
    }

I find following solution and its working perfectly.

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePictureIntent.setPackage(defaultCameraPackage); 
startActivityForResult(takePictureIntent, actionCode);

you can filter default camera by setting package in above intent. I've tested it by installing two application Line Camera and Paper Camera both apps were showing chooser but filtering by package above code open only default camera.
