Question

我正在使用我在GitHub上找到的裁剪工具。当我在一个单独的模块上实现它时，它工作得很好。但是，当我在实际应用程序中使用相同的代码时，我看到＆＃34; OutOfMemoryError＆＃34; .Below是代码片段。我花了很多时间在这上面，任何帮助都会受到高度赞赏。

扫描活动：

SELECT Distinct S.[Last Name] , S.Status, R.Risk  
FROM Status S
INNER JOIN Risk R
   ON R.[Last Name] = S.[Last Name]

// 441

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == Activity.RESULT_OK) {
        Uri imageUri = getPickImageResultUri(data);

activity_scan.xml：仅发布基本代码

       ((CropImageView) findViewById(R.id.CropImageView)).setImageUri(imageUri);
    }
}

Log cat说：
