android get Bitmap or sound from assets
The accepted answer never closes the InputStream
. Here is a utility method for getting a Bitmap
in the assets folder:
/**
* Retrieve a bitmap from assets.
*
* @param mgr
* The {@link AssetManager} obtained via {@link Context#getAssets()}
* @param path
* The path to the asset.
* @return The {@link Bitmap} or {@code null} if we failed to decode the file.
*/
public static Bitmap getBitmapFromAsset(AssetManager mgr, String path) {
InputStream is = null;
Bitmap bitmap = null;
try {
is = mgr.open(path);
bitmap = BitmapFactory.decodeStream(is);
} catch (final IOException e) {
bitmap = null;
} finally {
if (is != null) {
try {
is.close();
} catch (IOException ignored) {
}
}
}
return bitmap;
}
public static Bitmap getBitmapFromAsset(Context context, String filePath) {
AssetManager assetManager = context.getAssets();
InputStream istr;
Bitmap bitmap = null;
try {
istr = assetManager.open(filePath);
bitmap = BitmapFactory.decodeStream(istr);
} catch (IOException e) {
// handle exception
}
return bitmap;
}
the path is simply your file name fx bitmap.png. if you use subfolder bitmap/ then its bitmap/bitmap.png
Use this code its working
try {
InputStream bitmap=getAssets().open("icon.png");
Bitmap bit=BitmapFactory.decodeStream(bitmap);
img.setImageBitmap(bit);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Update
While decoding Bitmap we more often meet with memory overflow exception if Image size is very big. So reading article How to display Image efficiently will help you.
