常见场景：
通过BitmapFactory.decodeResource的方式，设置Notification的LargeIcon，当APP适配了自适应Icon后，获取不到Bitmap对象。
方式一：
public Bitmap getAppIcon(Context context) { if (context == null) { return null; } try { PackageManager packageManager = context.getApplicationContext().getPackageManager(); String packageName = context.getApplicationContext().getPackageName(); Drawable drawable = packageManager.getApplicationIcon(packageName); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { if (drawable instanceof BitmapDrawable) { return ((BitmapDrawable) drawable).getBitmap(); } else if (drawable instanceof AdaptiveIconDrawable) { Drawable[] drr = new Drawable[2]; drr[0] = ((AdaptiveIconDrawable) drawable).getBackground(); drr[1] = ((AdaptiveIconDrawable) drawable).getForeground(); LayerDrawable layerDrawable = new LayerDrawable(drr); int width = layerDrawable.getIntrinsicWidth(); int height = layerDrawable.getIntrinsicHeight(); Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bitmap); layerDrawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight()); layerDrawable.draw(canvas); return bitmap; } } else { return ((BitmapDrawable) drawable).getBitmap(); } } catch (Exception e) { e.printStackTrace(); } return null;} 方式二：
public Bitmap getAppIcon(Context context) { if (context == null) { return null; } try { PackageManager packageManager = context.getApplicationContext().getPackageManager(); String packageName = context.getApplicationContext().getPackageName(); Drawable drawable = packageManager.getApplicationIcon(packageName); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { if (drawable instanceof BitmapDrawable) { return ((BitmapDrawable) drawable).getBitmap(); } else if (drawable instanceof AdaptiveIconDrawable) { Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bitmap); drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight()); drawable.draw(canvas); return bitmap; } } else { return ((BitmapDrawable) drawable).getBitmap(); } } catch (Exception e) { e.printStackTrace(); } return null;}
