Start Activity Android with class name
android, android-activity, classname
Solution
You can use this snippet to open `Settings` Activity :
Intent intent=new Intent();
intent.setComponent(new ComponentName("com.android.settings", "com.android.settings.Settings"));
startActivity(intent);
If you do not know what Activity you have to open,you can find it's name and it's package name as I mentioned here.
Problem
I am using Following Code to start setting I want to launch the setting activity which is started by android ins ``` PackageList allowedAppsPackageName=CallHelper.Ds.getPackageList(); PackageManager manager = CallDetectService.packageManager; Intent mainIntent = new Intent(Intent.ACTION_MAIN, null); mainIntent.addCategory(Intent.CATEGORY_LAUNCHER); final List<ResolveInfo> apps = manager.queryIntentActivities(mainIntent, 0); Collections.sort(apps, new ResolveInfo.DisplayNameComparator(manager)); final int count = apps.size(); ResolveInfo info=new ResolveInfo();; GridViewAppList.clear(); for (int i = 0; i < count; i++) { info= apps.get(i); if(info.activityInfo.applicationInfo.packageName.contains("setting")) break; } ApplicationInfo application = new ApplicationInfo(); application.title = info.loadLabel(manager); application.setActivity(new ComponentName( packageName, info.activityInfo.name), Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); application.icon = info.activityInfo.loadIcon(manager); application.packagename=packageName; Log.i("PKG", application.packagename+" "+packageName+" "+info.activityInfo.name); GridViewAppList.add(application); ```
