Hello,
I want to store image in sqlite database.
I tried to store it using BLOB and String, in both cases it store the
image and can retrieve it but when i convert it to Bitmap using
BitmapFactory.decodeByteArray(...) it return null.
Below is my code please have a look and suggest me where i m making
mistake.
public class imagesql extends Activity {
/** Called when the activity is first created. */
Bitmap bi=null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
InputStream in=this.getResources().openRawResource
(R.drawable.dig);
bi = BitmapFactory.decodeStream(in);
Log.i("bitmap1",""+bi);
ImageView iv1=(ImageView)findViewById(R.id.img1);
iv1.setImageBitmap(bi);
String str= convertBitmapToString(bi);
Log.i("image string",str);
myDB a=new myDB(this);
a.open();
a.insertTag(str);
Cursor c=a.fetchData(myDB.TABLE_NAME_TAG,new String[]
{myDB.KEY_TAG_IMG},null,null);
startManagingCursor(c);
int rc=c.getCount();
ImageView iv;
c.moveToFirst();
if(rc!=0)
{
String s=c.getString(0);
Log.i("cursor string image",s);
Bitmap bitmap=getBitMapFromString(s);
Log.i("bitmap2",""+bitmap);
iv=(ImageView)findViewById(R.id.img);
iv.setImageBitmap(bitmap);
}
}
public static String convertBitmapToString(Bitmap src)
{
ByteArrayOutputStream os=new ByteArrayOutputStream();
src.compress(android.graphics.Bitmap.CompressFormat.PNG, 100,
(OutputStream) os);
return os.toString();
}
public static Bitmap getBitMapFromString(String src)
{
Log.i("b=",""+src.getBytes().length);//returns 12111 as a length.
return BitmapFactory.decodeByteArray(src.getBytes(),0,src.getBytes
().length);
}
}
