推荐答案

如果您要运行只有官方的摄像头，你可以使用下面的意图（基于的官方教程）：

If you want to run only the official camera, you can use the following intent (based on the official tutorial):

static final int REQUEST_IMAGE_CAPTURE = 1;

private void dispatchTakePictureIntent() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    takePictureIntent.setPackage("com.android.camera");
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
    }
}

不幸的是，许多设备都使用自定义preinstalled摄像头的应用程序，而 com.android.camera 可能无法使用。

如果你想筛选出特定的软件包，你不喜欢，你必须prepare你自己的选择对话框（见例的这里）。如果你知道选择哪个包，你可以跳过对话。例如。是可能的过滤列表，从而只包括系统的包。但即便如此，也不能保证会有只有一个注册到完成的 MediaStore.ACTION_IM​​AGE_CAPTURE 意图系统包。

If you want to filter out specific packages that you don't like, you must prepare your own chooser dialog (see example here). You can skip the dialog if you know which package to choose. E.g. it is possible to filter the list to only include "system" packages. But even then, there is no guarantee that there will be only one system package that is registered to fulfill the MediaStore.ACTION_IMAGE_CAPTURE intent.
