Android常见的错误整理（不定时更新）

1.将Bitmap影像到FrameLayout，我解码的图像转换成 Drawable ，然后将其设置为背景的 FrameLayout 
java.lang.NoSuchMethodError: android.widget.FrameLayout.setBackground()
    ByteArrayInputStream p_w_picpathStream2= new ByteArrayInputStream(cardbackground);

Bitmap Imagebackground = BitmapFactory.decodeStream(p_w_picpathStream2);

Drawable p_w_picpathbakground=new BitmapDrawable(getResources(),Imagebackground);

framelayout.setBackground(p_w_picpathbakground);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {

        framelayout.setBackground(p_w_picpathbakground);

    } else {

        frameLayout.setBackgroundDrawable(p_w_picpathbakground);

    }
