Huawei phone write to external storage fails even that the permission added to the manifest

Hey I have developed an app that saves a picture to external storage using MediaStore library.
MediaStore.Images.Media.insertImage(
contentResolver,
takenImage,
imgName,
"Image Saved"
)
The function work on Samsung A30 and Xiomi devices however when testing on Huawei p90 it fails(not saving the image) and throwing permission denial exception:
java.lang.SecurityException: Permission Denial: writing com.android.providers.media.MediaProvider uri content://media/external/images/media from pid=15830, uid=10438 requires android.permission.WRITE_EXTERNAL_STORAGE, or grantUriPermission()
However I do have the android.permission.WRITE_EXTERNAL_STORAGE permission in the manifest, when the is running I am prompted with a permission request (dealing with the runtime permission via CameraKit function and package)
Anything I missed?

Please check in manifest for the desired permission.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

SecurityException when using uses-permissions

I have two apps : App1 and App2
In App1 specified permission like this
<uses-permission android:name="com.commonname.providers.app2.READ_LOGIN_TOKEN" />
In App2 specified peromission like this
<uses-permission android:name="com.commonname.providers.app1.READ_LOGIN_TOKEN" />
I have installed applications in order: first App1 then App2.
When I run App1 I received SecurityException, like this:
Writing exception to parcel
java.lang.SecurityException: Permission Denial: reading
com.commonname.providers.App1 uri
content://com.commonname.providers.app1/logintoken from pid=5550,
uid=10919 requires com.commonname.providers.app1.READ_LOGIN_TOKEN,
or grantUriPermission()

at android.content.ContentProviderNative.onTransact(ContentProviderNative.java:112)
at android.os.Binder.execTransact(Binder.java:565)
Is exists way to request permissions again, while running application?
Or other way to grand access to this permission if application was installed first.
I have read this article https://github.com/commonsguy/cwac-security/blob/master/PERMS.md#android-50-behavior, and known depending from install order, but maybe exists some way.

It depens on your SDK version, if it higher than 23 you must request permissions runtime.

SamsungBadger doesn't work on Nougat

i have a problem with samsungBadger library, https://github.com/shafty023/SamsungBadger
i get the following error on nougat:
Writing exception to parcel
java.lang.SecurityException: Permission Denial: writing com.sec.android.provider.badge.BadgeProvider uri content://com.sec.badge/apps from pid=15661, uid=10234 requires com.sec.android.provider.badge.permission.WRITE, or grantUriPermission()

at android.content.ContentProviderNative.onTransact(ContentProviderNative.java:163)
at android.os.Binder.execTransact(Binder.java:573)
I tested this library with android 6.0 and work properly.
Can someone help me to fix this problem?
It'is very strange that android does not provide any native method to add badge on icon.
Thanks,

Android - Workaround the ACCESS_CONTENT_PROVIDERS_EXTERNALLY permission?

I'm building an application which gives this exception because i call some internal methods
Permission Denial: Do not have permission in call getContentProviderExternal() from pid=2520, uid=10047 requires android.permission.ACCESS_CONTENT_PROVIDERS_EXTERNALLY
java.lang.SecurityException: Permission Denial: Do not have permission in call getContentProviderExternal() from pid=2520, uid=10047 requires android.permission.ACCESS_CONTENT_PROVIDERS_EXTERNALLY
I did some search and i knew that android OS gives this permission only for the shell users,
I wonder if there exists any workaround this ..
Is there anything that would allow me to trick android and makes my application looks like a shell user?
Note: I tried to add the permission in the manifest file but obviously it didn't work.

Android SecurityException: no permission to uri

I try from my app to query content provider of an other app (not my app).
The provider in that app is defined with:
android:readPermission="android.permission.BIND_APPWIDGET"
android:grantUriPermissions="true"
From my app i added the user permission android.permission.BIND_APPWIDGET to manifest file but i get:
java.lang.SecurityException: Permission Denial: opening provider com.* from ProcessRecord{427afe60 29052:*/u0a72} (pid=29052, uid=10072) requires android.permission.BIND_APPWIDGET or com.*.ACCESS
Does anyone have and idea?

You can't give your application BIND_APPWIDGET since that is a signature|system permission. See the Android core resources manifest for more information.
