How to get Usage Access Permission programmatically

You can simply give this Permission on the manifest, ignoring just this permission error:

<uses-permission android:name="android.permission.PACKAGE_USAGE_STATS" tools:ignore="ProtectedPermissions"/>

Than use Following code for permission

@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    if (!isAccessGranted()) {        Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);        startActivity(intent);    }}private boolean isAccessGranted() {        try {            PackageManager packageManager = getPackageManager();            ApplicationInfo applicationInfo = packageManager.getApplicationInfo(getPackageName(), 0);            AppOpsManager appOpsManager = (AppOpsManager) getSystemService(Context.APP_OPS_SERVICE);            int mode = 0;            if (android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.KITKAT) {                mode = appOpsManager.checkOpNoThrow(AppOpsManager.OPSTR_GET_USAGE_STATS,                        applicationInfo.uid, applicationInfo.packageName);            }            return (mode == AppOpsManager.MODE_ALLOWED);        } catch (PackageManager.NameNotFoundException e) {            return false;        }    }
