在清单中添加“使用权限”无效

Question

SLOVED

Sending the intent like

Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);

In the onActivityResult method

imageUri = data.getData();
    getContentResolver().takePersistableUriPermission(imageUri, Intent.FLAG_GRANT_READ_URI_PERMISSION);

I have found that this is a common issue. I am getting a java.lang.SecurityException: Permission Denial: error when trying to userImg.setImageURI(tmp.photo); in my code. I have tried many solutions found on SO but nothing. I also tried using glide but no luck there. The uri is read into an object, which I store in memory on runtime, and I request it with tmp.photo . I checked with logging that the Uri is passed successfully into the photo attribute. What can I do?

these are into my manifest.

<uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

My code is very simple.

ImageView userImg = (ImageView) findViewById(R.id.userImg);
userImg.setImageURI(tmp.photo);

where tmp.photo is a Uri object. This generates all of these

Answer 1

You only have rights to the content identified by the Uri :

• In your original component (eg, the activity that got the Uri via onActivityResult() of ACTION_GET_CONTENT ), or

• In any components that you pass the Uri to, if you include FLAG_GRANT_READ_URI_PERMISSION in the Intent used to start that component, and

• Only while your process is around

In your case, somewhere along the line, you violated those rules. Perhaps you passed the Uri to another component without FLAG_GRANT_READ_URI_PERMISSION , or perhaps you saved the Uri to disk and attempted to use it again later.

See this blog post for more about Uri access lifetime.
