Question

我正在尝试启动相机活动，并通过Uri将结果发送回父活动。当我尝试通过按钮启动活动时，只要按下按钮，程序就会崩溃。

public class First_Page extends AppCompatActivity {

    public static final int CAMERA_REQUEST = 10;
    private Uri imageUri;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_first__page);
    }

    public void cameraClicked(View view){
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
        startActivityForResult(intent, CAMERA_REQUEST);
    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if(resultCode == RESULT_OK && resultCode == CAMERA_REQUEST){
            imageUri = data.getData();
        }
    }
}

这是logcat：

Answer 1

我在桌面上使用Android模拟器来运行该软件。显然这导致了这个问题，因为如果我在我的设备上运行它，它可以很好地工作。显然，模拟器无法处理相机。
