android-permissions

I'm developing an android app in which I have to ask for permissions at runtime. I'm wondering about the best way to implement that using Model-View-Presenter architecture. My initial thought was to have the presenter call a component responsible for permissions(say a PermissionHandler ), and update view accordingly. The issue is that the code to check for permissions is tightly coupled with the Activity class. Here are some of the methods involved that require an Activity or Context: ContextCompat.checkSelfPermission() ActivityCompat.shouldShowRequestPermissionRationale() ActivityCompat

I'm developing an application that going to be pr-installed (as a system app) on the firmware. from the documentation so far about the relation between system apps , new permissions model, and the protection levels - I don't understand exactly when system app needs (if at all) to request user permission. My problems starts when I try to use the WRITE_EXTERNAL_STORAGE permission. from the documentation I can see that it marked as "dangerous" permission. - does "dangerous" permissions grant automatically to system apps? when I use WRITE_EXTERNAL_STORAGE permission (as a system app) I'm getting

I think I've tried all the solutions I found on the internet, but no one worked - no force close, but nothing appears on desktop. Now, I have this: private void createShortcutOnDesktop(Application app) { Intent shortcutIntent = new Intent(); shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, app.getIntentShortcut()); shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, app.getName()); shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(context, R.drawable.home_button)); shortcutIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");

Say you have a method like this: public boolean saveFile (Url url, String content) { // save the file, this can be done a lot of different ways, but // basically the point is... return save_was_successful; } Throughout your app, if you want to save a file to external storage, you do something like... if (saveFile(external_storage_url, "this is a test")) { // yay, success! } else { // notify the user something was wrong or handle the error } This is a simplified example, so don't get on my case about blocking the UI, handling exceptions properly, etc. If you don't like file saving, you could

I want to ask user does he want to grant a permission to accces his fine location and only if he grant it I want to replace a fragment and open the locator fragment. In locator fragments there are some stores that user can see based on his location. If he doesn't allow access to fine location I want to show him proper message. This is the code: else if (id == R.id.nav_locator) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1); fragment = new LocatorFragment(); FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); ft.replace

Below code is working fine on pre-Marshmallow devices but not in Marshmallow. These are the permissions in Manifest <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> Here is the code public void saveImageToSDCard(Bitmap bitmap) { File myDir = new File( Environment .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), pref.getGalleryName()); myDir.mkdirs(); Random generator = new Random(); int n = 10000; n = generator
