Я создаю приложение, в котором мне нужно нарисовать изображение на холсте, а затем СОХРАНИТЬ это изображение в общих настройках, а затем показать на следующем экране. Любая помощь будет оценена
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new DrawingPanel(this));
mPaint = new Paint();
mPaint.setDither(true);
// mPaint.setColor(0xFF FF FF FF);
System.out.println("hello1");
mPaint.setColor(Color.BLACK);
System.out.println("hello2");
mPaint.setStyle(Paint.Style.STROKE);
mPaint.setStrokeJoin(Paint.Join.ROUND);
mPaint.setStrokeCap(Paint.Cap.ROUND);
mPaint.setStrokeWidth(3);
}

System.out.println("hii3");
// File f1=new File("/sdcard/" + date1 + ".png");
System.out.println("hii4");
// FileSave fs = null;
// fs.Save(f1);
// Add a new record without the bitmap, but with the values just set.
// insert() returns the URI of the new record.
// Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
