Getting NoSuchMethodError Using TextView Methods

I get a NoSuchMethodError with the class I created that extends TextView . The only thing I did was add some variables and add onLongClickListener . No more changes.

Everything works fine when I use my application in my Android phone 4.1.2 But in my other phone which is 4.0.3, it throws this NoSuchMethodError .

Here is the code when I create a class that extends Textview:

 descrip=new TextViewList(context, admin, this); descrip.setPadding(0, 15, 0, 15); descrip.setGravity(Gravity.CENTER); descrip.setTextAlignment(Gravity.CENTER); descrip.setText(c.getString(c.getColumnIndex("Descripcion"))); descrip.setTag(c.getString(c.getColumnIndex("ID"))); descrip.setWidth(LinearLayout.LayoutParams.MATCH_PARENT); descrip.setHeight(LinearLayout.LayoutParams.MATCH_PARENT); descrip.setBackground(img); layDescripcion.addView(descrip);

First, he threw an exception using setTextAlignment , then I removed it and threw it again using the setBackground method.

What causes this error? Does this mean that my application is not compatible with Android version lower than 4.1.2? I set minimun to 2.2 when I created the project. And I use the android.support.v4 libraries where they are requested.

Here is the LogCat:

setBackground() introduced only in 16 api . Use setBackgroundDrawable() .

that all phones that have less than 16 api will support setBackgroundDrawable()

Workaround for this problem:

 Drawable d = this.res.getDrawable(R.drawable.metro_circle); if ( Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN ) { metroIconTextView.setBackground(d); } else { metroIconTextView.setBackgroundDrawable(d); }
