【问题描述】：
基本上我从图库中接收到图像的 URI，然后创建了一个位图并希望发送到另一个活动进行显示：
Uri imageUri = intent.getData();
mBitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri);
Intent intent = new Intent(TakePictureActivity.this, PreviewActivity.class);
intent.putExtra(EXTRA_BITMAP_DATA, mBitmap);
startActivityForResult(intent, REQUEST_PREVIEW);
当我什么都不做的时候，PreviewActivity 可以正常触发。但是，当我放置位图时，模拟器一直冻结，直到我强制关闭。这种情况发生在我身上好几次了，我一直试图通过发送 Bitmap 对象以外的其他东西来解决这个问题。
但这一次我想我不能。我不想通过传递图像的 Uri 来更改 API，因为其他一些活动已经在向它发送位图。这是一个特例。
这是冻结期间 LogCat 的输出：

并非所有位图都会出现这种情况。这个特定的位图来自一个~300K 的文件，但我不知道它是否与大小有关。这是我的错吗？有人经历过吗？
非常感谢
