Clear app data and get Icon

1. eliminate data

need Configure permissions  

<uses-permission android:name="android.permission.ACCESS_INSTANT_APPS"/>

    public static boolean clearData(String pkg){
        Context context = HwContext.getContext();
        ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        am.clearApplicationUserData(pkg,null);
        return true;
    }

perhaps

try {
                Process exec = Runtime.getRuntime().exec("pm clear " + pkg);
                exec.getInputStream().read(clearDataResult); To get the results 
            } catch (IOException e) {
                e.printStackTrace();
            }

2. obtain app Icon

PackageManager pm = getPackageManager();
        PackageInfo packageInfo = null;
        try {
            packageInfo = pm.getPackageInfo(getPackageName(),0);
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }

        Drawable drawable = packageInfo.applicationInfo.loadIcon(pm);

preservation icon

    Drawable icon = t.getIcon();
                File file = new File("icon.png");
                try {
                    Bitmap bm = drawableToBitmap(icon);
                    FileOutputStream out = new FileOutputStream(file);
                    bm.compress(Bitmap.CompressFormat.PNG, 90, out);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
              
  

    public Bitmap drawableToBitmap(Drawable drawable) {
        Bitmap bitmap = Bitmap.createBitmap(
                drawable.getIntrinsicWidth(),
                drawable.getIntrinsicHeight(),
                drawable.getOpacity() != PixelFormat.OPAQUE ? Bitmap.Config.ARGB_8888 : Bitmap.Config.RGB_565);
        Canvas canvas = new Canvas(bitmap);
        // canvas.setBitmap(bitmap);
        drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),drawable.getIntrinsicHeight());
        drawable.draw(canvas);
        return bitmap;
    }

3. Simulate click events

    public void constructClickEvent(int x,int y){
        List<String> commands = new ArrayList<String>();
        commands.add("input");
        commands.add("tap");
        commands.add("" + x);
        commands.add("" + y);

        try {
            Process start = new ProcessBuilder(commands).start();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

4. Simulate sliding events

  public void constructSlideEvent(int x,int y,int newX,int newY){
        InputStream is = null;
        ByteArrayOutputStream baos = null;
        List<String> commands = new ArrayList<String>();
        commands.add("input");
        commands.add("swipe");
        commands.add("" + x);
        commands.add("" + y);
        commands.add("" + newX);
        commands.add("" + newY);
        ProcessBuilder pb = new ProcessBuilder(commands);
        try {
            Process prs = pb.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
