Question

我正在尝试使用从特定网址下载的图片在主屏幕上创建快捷方式。我做的是，我从URL下载了图像并将其转换为位图并尝试创建快捷方式。但该应用程序崩溃显示以下错误。

错误：

以下是我用来创建快捷方式的代码。

  public static void createShortcutIcon(Activity a, Context c, Categories parentCategory,
      Bitmap bitmap) {

    // Apend the entityName so we know what we are specifically looking for
    PREF_KEY_SHORTCUT_ADDED += "_" + parentCategory.getId();

    // Checking if ShortCut was already added
    SharedPreferences sharedPreferences =
        c.getSharedPreferences(Constants.APP_PREF_ID, Context.MODE_PRIVATE);
    boolean shortCutWasAlreadyAdded = sharedPreferences.getBoolean(PREF_KEY_SHORTCUT_ADDED, false);
    if (shortCutWasAlreadyAdded) return;

    Intent shortcutIntent = new Intent(c.getApplicationContext(), MainActivity.class);
    shortcutIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

    Intent addIntent = new Intent();
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, parentCategory.getName());

    addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON, bitmap);

    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putBoolean(PREF_KEY_SHORTCUT_ADDED, true);
    editor.apply();

    addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
    addIntent.putExtra("duplicate", false);
    c.sendBroadcast(addIntent);

    // Remembering that ShortCut was already added

    Timber.d("Completed shortcut creation");
  }

我真的被困在这里了。无法为此找到任何解决方案。

我还尝试使用以下代码调整位图大小：

public Bitmap getResizedBitmap(Bitmap image, int maxSize) {
    int width = image.getWidth();
    int height = image.getHeight();

    float bitmapRatio = (float) width / (float) height;
    if (bitmapRatio > 1) {
      width = maxSize;
      height = (int) (width / bitmapRatio);
    } else {
      height = maxSize;
      width = (int) (height * bitmapRatio);
    }

    return Bitmap.createScaledBitmap(image, width, height, true);
  }

但使用此位图调整大小后不再有效。我不能在imageview上显示它。请帮忙。

从here得到答案。

使用以下try{ doc = Jsoup.connect( URL ). userAgent(“chrome/34.0.1847.131”) .header(“Authorization”,”Basic”+encodedString) .followRedirects(true) .maxBodySize(0) .get(); } catch (IOException e) { }

缩放位图

code.

现在它正在运作。
