java.lang.OutOfMemoryError编码位图为Base64

我得到这个例外java.lang.OutOfMemoryError编码位图为Base64

唯一的例外是在这条线：

files+="[\""+encodeTobase64(myImages.get(i))+"\",\""+i+"image.jpg\"]";

myImages - 位图

public static String encodeTobase64(Bitmap image) { 
    ByteArrayOutputStream baos=new ByteArrayOutputStream(); 
    image.compress(Bitmap.CompressFormat.JPEG,100, baos); 
    byte [] b=baos.toByteArray(); 
    String temp=null; 
    try{ 
     System.gc(); 
     temp=Base64.encodeToString(b, Base64.DEFAULT); 
    }catch(Exception e){ 
     e.printStackTrace(); 
    }catch(OutOfMemoryError e){ 
     baos=new ByteArrayOutputStream(); 
     image.compress(Bitmap.CompressFormat.JPEG,50, baos); 
     b=baos.toByteArray(); 
     temp=Base64.encodeToString(b, Base64.DEFAULT); 
     Log.e("EWN", "Out of memory error catched"); 
    } 
    return temp; 
}

的数组列表这取决于照片，当我从照相机加载3张照片到位图阵列 - 当来自Galery的3张照片时 - 一切都很好 - 出现错误。
