I always Getting a Permission Prompt by default while installing a new app. How can i give permission without prompt while developing app.
Set your target SDK version to less then 23, i.e. 22 or below in your module's build.gradle file if you do not want to prompt for permission while running the app.

recently I get Installed blocked : The app permissions error error when updating my application(in app updating).
I know my app signatures are same because I can install new app manually.
can some know why this happen?
Do you think I need to grant android.permission.INSTALL_PACKAGES while I granted android.permission.REQUEST_INSTALL_PACKAGES? if yes can explain deference of both?
Note: my application updated correctly in many devices!! but in some devices(android Version: 5.1.1) have problem!!!
The INSTALL_PACKAGES permission allows an application to install packages. It is not for use by third-party applications.
Developers of apps that require the ability to download and install other apps via the Package Installer may need to make some changes. If an app uses a targetSdkLevel of 26 or above and prompts the user to install other apps, the manifest file needs to include the REQUEST_INSTALL_PACKAGES permission.

I have created Android app a while ago.
this app use inside the company. we not uploaded to Google play store. Just install APK.
and now I updated the app with the new resource. while update app install screen ask from users to New or All
see the photo
I want to skip or hide this screen
just install all data without ask.
how can I do this?
thank you
It is the old permissions screen.
If the device is running Android 5.1 or lower, or your app's target SDK is 22 or lower, if you list a dangerous permission in your manifest, the user has to grant the permission when they install the app; if they do not grant the permission, the system does not install the app at all.
You can't skip it.
Instead if the device is running Android 6.0 or higher, and your app's target SDK is 23 or higher you can use the runtime permissions.
Check here for more details.
I am facing a very different problem with Android permission : android.permission.READ_LOGS with the target sdk v22.
This permission was not present in old version of the app v1.1 and I introduced this permission in v1.2 to read logs.
Now, when I update the app from v1.1 to v1.2, manually from the apk placed in the phone locally, I don't see any warning that there was any new permission added with the newer version of the app and if I install the same version from the Google play store, I see a warning that there is a new permission added with this version of the app.
The more strange thing for me is to see that the phone doesn't show this permission in the permission section in the app settings at all.
If a user installs an app with some permissions in Lollipop, and then updates to Marshmallow,
will the permissions of the app be granted or will them all be revoked by default and permission granting window be needed again?
The app is build with Android M as target sdk
F.E. My app has a process that runs on the background and requires a permission, the Lollipop user installs the app and it goes ok, but then updates the phone to Marshmallow.
Will the app process fail until the user grants the permission?
The app is build with Android M as target sdk
Yes, you need to update your app to request the user for the permissions as required by your app otherwise your app may crash.
If your app's target sdk would have been less than 23, then your app would work without any issues.
My project is a long running project. I had set the target version as 10, 4 years back. I cant change the target version to 23, since I am using httpImageCache and also having issues with UI's. My problem is, when Marshmallow released I tried to integrate Marshmallow with targetVersion 10,
int returnedPermission = ContextCompat.checkSelfPermission(MyActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
this function is always returing '0' if I manually ON or Off storage permission from App Settings page. Can any one please help me?
As #Commonware has already given the answer, but here I am adding more detail to the question which might help you.
As per the official android developer site:
If the device is running Android 5.1 or lower, or your app's target
SDK is 22 or lower: If you list a dangerous permission in your
manifest, the user has to grant the permission when they install the app; if they do not grant the permission, the system does not install the app at all.
If the device is running Android 6.0 or higher, and your app's target
SDK is 23 or higher: The app has to list the permissions in the
manifest, and it must request each dangerous permission it needs
while the app is running. The user can grant or deny each permission,
and the app can continue to run with limited capabilities even if the
user denies a permission request.
As your target SDK is 10, application will run perfectly like previous. Anyway please note that user still can revoke a permission after that..!!! Although Android 6.0 warn the user when they try to do that but they can revoke anyway.
Above statement is taken from official android developer site.
Can any one please help me?
Delete that code, as it is useless for you. If your targetSdkVersion is below 23, you cannot find out whether or not the user revoked permissions.
use PermissionChecker.checkSelfPermission()
when targetSdkVersion <= 22,you also can use requestPermission()
