Unfortunately, Package Installer has stopped while requesting permission in Marshmallow

Question

I am trying to request permission to seek permission to read storage. After recent Android Studio upgrade, I started getting error "Unfortunately, Package Installer has stopped" while requesting permission and the permission request dialog does not come up.

Here is the code snippet where I am requesting the permission

    int readPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE);
    int writePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
    if (readPermission != PackageManager.PERMISSION_GRANTED || writePermission != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE},
                REQUEST_READWRITE_STORAGE);
    }
}

Answer 1

I had the same issue. I forgot to add same permissions in manifest. I added these permissions in manifest as well, as mike said. Then clean and build and it worked like a charm.

Conclusion: If you are giving the permissions programmatically in class then make sure the same permissions you must declare in AndroidManifest.xml file.

Answer 2

I had tried this on 2 phones but no luck.

This time, I added the permissions back to manifest file, did clean project and ran again. It worked this time.
