How to:
allprojects { repositories { ... maven { url 'https://jitpack.io' } } }dependencies { implementation 'com.github.dec04:PermissionUtilsLibrary:1.0.1' }In order for each permission to show its explanation, you need to add lines in the strings.xml file Required format for string resource names is PERMISSION_NAME + _EXPLANATION
For example if you request this permissions (ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION, WRITE_EXTERNAL_STORAGE) names must be:
<string name="ACCESS_FINE_LOCATION_EXPLANATION">Some explanation</string> <string name="ACCESS_COARSE_LOCATION_EXPLANATION">Some explanation</string> <string name="WRITE_EXTERNAL_STORAGE_EXPLANATION">Some explanation</string>Code from my google map example:
Context applicationContext; PermissionUtils permissionUtils; String[] permissions = { Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.WRITE_EXTERNAL_STORAGE };Usually in a method OnCreate:
applicationContext = GoogleMapActivity.this; permissionUtils = new PermissionUtils(applicationContext);Check permissions:
// ... some code ... // Check all permissions if (permissionUtils.check(permissions)) { // if permissions already taken // do something } else { // request permission permissionUtils.requestPermission(permissions); }If permission not taken, app request it from user. All at once.
Usualy in OnResume or OnResumeFragment method:
if (permissionUtils.flagPermissionDenied) { // Permission was not granted, display "permission rejected" dialog. permissionUtils.showMissingPermissionError(permissions); permissionUtils.flagPermissionDenied = false; }Now, if user reject permission app show window, explaining that the permit is not received.
The next time you request permissions, a window will be displayed explaining why you need each permission individually. In the last window, you can re-request permission.
You also need implement method onRequestPermissionsResult
@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { if (requestCode != PERMISSION_REQUEST_CODE) { return; } if (permissions.length != 0) { if (!permissionUtils.check(permissions)) { // Display the missing permission error dialog when the fragments resume. permissionUtils.flagPermissionDenied = true; } else { // For example enable the "my location layer" if the permission has been granted. } } }That's all. Happy hacking. 💟
p.s.
