从图库中显示图片时，应用程序会中断

抱歉我的英语。

该应用程序正常运行。将文件附加到imageview，然后将其发送到服务器。

现在，在选择图片（文件）后，应用程序会在imageview中显示它，所有方法都能正确运行到最后。

但应用程序会将我抛给上一个片段而日志中没有任何错误。

 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(resultCode == Activity.RESULT_OK && requestCode == 100){

        if(getPath(data.getData()) != null){

        Uri fileUri = data.getData();
        file = new File(getPath(fileUri));

        String mimetype = getActivity().getContentResolver().getType(fileUri);
        Log.d("mylog","name " + file.getName() + " type " + mimetype);

        imageV.setVisibility(View.VISIBLE);
        imageV.setImageResource(R.drawable.icons8highpriority96);

        if(mimetype.equals("image/jpeg")){ imageV.setImageURI(fileUri);}
        if(mimetype.equals("image/png")){ imageV.setImageURI(fileUri);}
        if(mimetype.equals("application/pdf")){ imageV.setImageResource(R.drawable.icons8pdf80);}
        if(mimetype.equals("text/html")){ imageV.setImageResource(R.drawable.icons8doc80);}

        textFileName.setText(file.getName());
        textFileName.setVisibility(View.VISIBLE);


    }else {
            imageV.setVisibility(View.VISIBLE);
            textFileName.setVisibility(View.VISIBLE);
            textFileName.setText("Выберите файл из определенного раздела! ");}

    }

}

我附上了一些令我困惑的日志 -

我将我的代码复制到一个新项目中并且它有效！ 来自activi和fragment。 但在与画廊互动后的主要项目中，片段已关闭。

我建议你逐行调试你的代码，我觉得有些东西是空的。在不同的sdk中，获取Path（文件Uri）是不同的

你可以遵循这个结构。用你的变量和方法替换变量和方法。希望它会对你有所帮助。请评论任何查询。

我发现了我的错误。 该应用程序已关闭，因为我在主要活动的onStart方法中调用了另一个片段。
