Error while trying to display a vector imageView (SVG)!

In newer versions of Android Studio, you can use SVG files without resorting to external libraries.

Right-click on the drawable folder and on the menu that opens, choose new-> Vector Asset .

In the Local file (SVG, PSD) window, specify the path to the file, click next and then finish in the next window .

Source: android documentation

This creates an xml file ( VectorDrawable ) that can be used like any other icon .

Note 1:

To use VectorDrawable in versions lower than Android 5.0 (API level 21) you need the Support Library 23.2.0 and configure build.gradle as follows:

//For Gradle Plugin 2.0+
 android {
   defaultConfig {
     vectorDrawables.useSupportLibrary = true
    }
 }

and instead of android:src you should use android:srcCompat . See the documentation for more complete information.

As pointed out by @rsicarelli, from the version 23.4 .0 of the Support Library is explicitly required to enable functionality by placing

static {
    AppCompatDelegate.setCompatVectorFromSourcesEnabled(true);
}

at the top of the Activity.

Note 2:

In the latest versions of the Support Library (25.1.1 on this date), as long as you do not worry about APK having a few more Kbs, you do not need to apply what is described in note 1.
Android Studio generates a PNG for each VectorDrawable to be used in versions under 21.

Note 3

Backwards compatibility is not always guaranteed.

This post explains in diagram form what is described in the notes.

Probably this error is because you are trying to get the file as an asset item " SVG svg = SVGParser.getSVGFromAsset (getResources (), R.raw.tree); " but probably the assets folder has not been defined, to create it, right click on project and choose new / folder / assets folder.

So try this:

//...
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main01);

    logo.setBackgroundColor(Color.WHITE);
    // SVG svg = SVGParser.getSVGFromAsset(getResources(), R.raw.tree);
    // melhor voce criar uma pasta assets, copiar o arquivo para ela e usar 
    final SVG svg = SVGParser.getSVGFromAsset(getAssets(), "tree.svg");
    logo.setImageDrawable(svg.createPictureDrawable());
    //setContentView(logo);
    // desnecessario essa linha
}
//...

It is never recommended to have the name of an activity with number or capital letters, so if possible, rename it to another name that contains only letters.
