冻结向活动发送某些位图

Question

基本上，我从图库接收图像的 URI，然后创建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);

当我没有添加任何内容时，PreviewActivity 可以正常触发。然而，当我放置位图时，模拟器一直冻结，直到我强行关闭。这种情况在我身上发生过好几次，我总是尝试通过发送位图对象以外的其他内容来解决这个问题。

但这次我想我不能了。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向其发送位图。这是一个特例。

以下是冻结期间 LogCat 的输出：

并非所有位图都会发生这种情况。这个特定的位图来自大约 300K 的文件，但我不知道它是否与大小有关。这是我的错吗？有人经历过这个吗？

非常感谢

Answer 1

压缩后可能有 300KB - 但分辨率是多少？取宽度，乘以高度，然后再乘以 4。

你解题的方法是错误的。
