android5.0需要适配的坑

1.BitmapFactory.decodeResource为null

xml定义的drawable不是vector，依然也会报这个错。

private static Bitmap getBitmap(Context context,int vectorDrawableId) {
    Bitmap bitmap=null;
    if (Build.VERSION.SDK_INT>Build.VERSION_CODES.LOLLIPOP){
        Drawable vectorDrawable = context.getDrawable(vectorDrawableId);
        bitmap = Bitmap.createBitmap(vectorDrawable.getIntrinsicWidth(),
                vectorDrawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        vectorDrawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
        vectorDrawable.draw(canvas);
    }else {
        bitmap = BitmapFactory.decodeResource(context.getResources(), vectorDrawableId);
    }
    return bitmap;
}
