Question

我正在使用Intent在我的应用程序中捕获照片：

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);

但是当我拍摄照片并单击“保存”按钮时，它会抛出错误：

liblog              failed to call dumpstate
AndroidRuntime      java.lang.NullPointerException

但是当我将这个应用程序用于不同的移动设备时，它可以完美地运行。我不知道是什么问题。

拍摄照片后的代码：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    try {
        if (requestCode == CAMERA_REQUEST) {

            Bitmap bitmap = (Bitmap) data.getExtras().get("data");
            imageViewPhoto.setImageBitmap(bitmap);

        }

    } catch (NullPointerException e) {
        Toast.makeText(this, "Problem while capturing photo. Try after some time.", Toast.LENGTH_LONG).show();
    }
}

捕获照片时出错（LinearLayout中的NullPointerException）
