How to tell which app was selected by Intent.createChooser?

Question

Code:

Intent launchIntent = new Intent(Intent.ACTION_MAIN);
launchIntent.addCategory(Intent.CATEGORY_HOME);
Intent chooser = Intent.createChooser(launchInten         


        

Answer 1

The CommonsWare's solution only works from Android 5.1 (API level 22). Here is my solution to work with all Android versions, by creating our own app chooser dialog.

Step 1: Create a custom layout for the app chooser dialog.

dialog_app_chooser.xml

Step 2: Create a layout for an item in app chooser dialog.

item_app.xml

Step 3: Create a model class which indicates an app in the app chooser dialog.

App.java

public class App implements Parcelable {
    public Intent intent;
    public ResolveInfo resolveInfo;

    public App(Intent intent, ResolveInfo resolveInfo) {
        this.intent = intent;
        this.resolveInfo = resolveInfo;
    }

    protected App(Parcel in) {
        intent = in.readParcelable(Intent.class.getClassLoader());
        resolveInfo = in.readParcelable(ResolveInfo.class.getClassLoader());
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeParcelable(intent, flags);
        dest.writeParcelable(resolveInfo, flags);
    }


    public static final Creator CREATOR = new Creator() {
        @Override
        public App createFromParcel(Parcel in) {
            return new App(in);
        }

        @Override
        public App[] newArray(int size) {
            return new App[size];
        }
    };
}

Step 4: Create a custom adapter which display all apps in the app chooser dialog.

AppAdapter.java

public class AppAdapter extends RecyclerView.Adapter {
    private List apps;
    private OnItemClickListener listener;

    public AppAdapter(List apps, OnItemClickListener listener) {
        this.apps = apps;
        this.listener = listener;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int position) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_app, parent, false);
        return new ViewHolder(view, listener);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder viewHolder, int position) {
        App app = apps.get(viewHolder.getAdapterPosition());
        viewHolder.bind(app);
    }

    @Override
    public int getItemCount() {
        return apps.size();
    }

    class ViewHolder extends RecyclerView.ViewHolder {
        private ImageView appIcon;
        private TextView appName;
        private App app;

        ViewHolder(View itemView, final OnItemClickListener listener) {
            super(itemView);
            appIcon = itemView.findViewById(R.id.image_view_app_icon);
            appName = itemView.findViewById(R.id.text_view_app_name);
            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    listener.onItemClick(app);
                }
            });
        }

        void bind(App app) {
            this.app = app;
            PackageManager packageManager = appName.getContext().getPackageManager();
            appIcon.setImageDrawable(app.resolveInfo.loadIcon(packageManager));
            appName.setText(app.resolveInfo.loadLabel(packageManager));
        }
    }

    interface OnItemClickListener {
        void onItemClick(App app);
    }
}

Step 5: Create the app chooser dialog.

AppChooserDialog.java

public class AppChooserDialog extends BottomSheetDialogFragment implements AppAdapter.OnItemClickListener {
    private static final String KEY_APPS = "KEY_APPS";
    private static final String KEY_TITLE = "KEY_TITLE";
    private static final String KEY_REQUEST_CODE = "KEY_REQUEST_CODE";

    public static void show(AppCompatActivity activity, ArrayList targets, String title, int requestCode) {
        PackageManager packageManager = activity.getPackageManager();
        ArrayList apps = new ArrayList<>();
        for (Intent intent : targets) {
            List activities = packageManager.queryIntentActivities(intent, 0);
            for (ResolveInfo resolveInfo : activities) {
                Intent targetIntent = new Intent(intent);
                apps.add(new App(targetIntent, resolveInfo));
            }
        }

        if (apps.size() > 0) {
            if (apps.size() == 1) {
                activity.startActivityForResult(apps.get(0).intent, requestCode);
            } else {
                DialogFragment appChooserDialog = new AppChooserDialog();
                Bundle data = new Bundle();
                data.putParcelableArrayList(KEY_APPS, apps);
                data.putString(KEY_TITLE, title);
                data.putInt(KEY_REQUEST_CODE, requestCode);
                appChooserDialog.setArguments(data);
                appChooserDialog.show(activity.getSupportFragmentManager(), "AppChooserDialog");
            }
        }
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.dialog_app_chooser, container, false);

        TextView titleTextView = rootView.findViewById(R.id.text_view_title);
        RecyclerView appsRecyclerView = rootView.findViewById(R.id.recycler_view_apps);

        String title = getArguments().getString(KEY_TITLE);
        if (!TextUtils.isEmpty(title)) {
            titleTextView.setText(title);
        }

        List apps = getArguments().getParcelableArrayList(KEY_APPS);
        appsRecyclerView.setAdapter(new AppAdapter(apps, this));

        DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
        float screenWidthInDp = displayMetrics.widthPixels / displayMetrics.density;
        int recyclerViewItemWidthInDp = 72;
        int recyclerViewStartEndPadding = 32;
        int numberOfColumns = (int) ((screenWidthInDp - recyclerViewStartEndPadding) / recyclerViewItemWidthInDp);
        int spanCount = (apps.size() < numberOfColumns) ? apps.size() : numberOfColumns;
        appsRecyclerView.setLayoutManager(new GridLayoutManager(requireActivity(), spanCount));

        return rootView;
    }


    @Override
    public void onItemClick(App app) {
        ActivityInfo activity = app.resolveInfo.activityInfo;
        String packageName = activity.applicationInfo.packageName;
        ComponentName component = new ComponentName(packageName, activity.name);

        Intent intent = new Intent(app.intent);
        intent.setComponent(component);

        Uri uri = app.intent.getParcelableExtra(MediaStore.EXTRA_OUTPUT);
        if (uri != null) {
            requireActivity().grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
        }

        OnAppSelectedListener listener = null;
        try {
            listener = (OnAppSelectedListener) requireActivity();
        } catch (Exception e) {
            // Ignore exception
        }
        if (listener != null) {
            listener.onAppSelected(intent);
        }

        requireActivity().startActivityForResult(intent, getArguments().getInt(KEY_REQUEST_CODE));
        dismiss();
    }

    public interface OnAppSelectedListener {
        void onAppSelected(Intent intent);
    }
}

Step 6: Using the app chooser dialog from an activity.

public class MainActivity extends AppCompatActivity implements AppChooserDialog.OnAppSelectedListener {
    private static final int REQUEST_CODE_PICK_IMAGE = 100;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ArrayList intents = new ArrayList<>();
        Intent pickImageIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        intents.add(pickImageIntent);
        AppChooserDialog.show(this, intents, "Pick image from", REQUEST_CODE_PICK_IMAGE);
    }

    @Override
    public void onAppSelected(Intent intent) {
        ComponentName componentName = intent.getComponent();
        String packageName = componentName.getPackageName();
        String activityName = componentName.getClassName();
        Log.i("TAG", "packageName = " + packageName + ", activityName = " + activityName);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == REQUEST_CODE_PICK_IMAGE) {
            Log.i("TAG", "onActivityResult");
            // TODO: Put your logic here.
        }
    }
}

The result:
