你也检查喜欢

    PackageManager pm = getPackageManager();
    if (pm.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
      // your Intent Goes Here Like
        Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        i.putExtra(MediaStore.EXTRA_OUTPUT,MyFileContentProvider.CONTENT_URI);
        startActivityForResult(i, CAMERA_RESULT);
    } else {   
        UtilityCommon.showDialogwithTitle(context,context.getResources().getString(R.string.strvalidcamera));               

    }

还要在您的AndroidMAnifest.xml文件中添加要求权限

Answer 2

add permission in your manifest file

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

<uses-permission
    android:name="android.permission.CAMERA"></uses-permission>

如果仍然无法正常工作，则编辑 AVD 并转到选定的后置摄像头模拟
