Java android安全异常

Question

在我的应用程序中，用户可以拍照或将照片添加到应用程序。当应用尝试在ImageView中显示保存的图像时，我收到java.lang.SecurityException的崩溃报告

错误所在的行是

holder.imageV.setImageURI(uriParsed);

我自己无法在设备或模拟器上重复该错误，它们都可以正常显示图像。

我正在使用的完整代码是

JoinProjectPicture projectPicture = mProjects.get(position);
Project current = projectPicture.getProject();
Picture picture = projectPicture.getPicture();

 holder.projectName.setText(current.getProjectName() + "(" + current.getWidth() + "x" + current.getHeight() + ")");
 holder.projectStatusTV.setText(current.getStatus());

 if(picture != null) {
      String pictureName = picture.getPictureName();
      Uri uriParsed = Uri.parse(pictureName);

      if(uriParsed != null) {
           Log.d("URIParsed", "Project: " + current.getProjectName() + " - Parsed: " + uriParsed);
           holder.imageV.setImageURI(uriParsed);
    }
}

在我的设备上显示的日志输出（3个项目，一个没有图像）

Answer 1

这是因为在新版本中Android 9引入了新的FOREGROUND_SERVICE权限；文档说：

\n\n

\n

注意：面向Android 9 (API level 28)或更高版本并使用前台服务的应用程序必须请求FOREGROUND_SERVICE permission. 这是正常权限，因此系统会自动将其授予请求的应用程序。\n 如果目标API level 28或更高版本的应用程序尝试在不请求 的情况下创建前台服务FOREGROUND_SERVICE，系统会抛出SecurityException.

\n

\n\n

只需将权限添加到清单中，“理论上”就可以解决问题。让我们知道！！\n类似：

\n\n

<manifest ...>   \n     <uses-permission android:name="android.permission.FOREGROUND_SERVICE" /> \n     <application ...>\n</manifest>\n

\n\n

让\xc2\xb4s 尝试获取赏金：\n你有这些权限吗？：

\n\n

<uses-permission android:name="android.permission.MANAGE_DOCUMENTS"/>\n<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>\n\n

\n\n

另外我认为尝试一下也不错：

\n\n

public static final String KITKAT_VALUE = 1002;\n\n  Intent intent;\n\n    if (Build.VERSION.SDK_INT < 19){\n                            intent = new Intent();\n                            intent.setAction(Intent.ACTION_GET_CONTENT);\n                            intent.setType("image/*");\n                            startActivityForResult(intent, KITKAT_VALUE);\n                        } else {\n                            intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);\n                            intent.addCategory(Intent.CATEGORY_OPENABLE);\n                            intent.setType("image/*");\n                            startActivityForResult(intent, KITKAT_VALUE);\n                    }\n\n@Override\npublic void onActivityResult(int requestCode, int resultCode, Intent data) {\n   if (requestCode == KITKAT_VALUE ) {\n     if (resultCode == Activity.RESULT_OK) {\n       // do something here\n     }\n  }\n}\n
