我已經編寫了用於從Carrousel滑塊中獲取當前頁面的代碼，並通過電子郵件和MMS使用Android中的Java爲手機項目共享。Android應用程序的Java代碼中的實例化異常
這是我的Java代碼：
public class Share extends CordovaPlugin {
private FileOutputStream outStream;
private File file;
Bitmap bm;
public static final String ACTION_POSITION = "ShareImage";
Context context;
public Share(Context context) {
this.context = context;
}
@Override
public boolean execute(String action, JSONArray args, CallbackContext callbackContext)
throws JSONException {
if (ACTION_POSITION.equals(action)) {
try {
JSONObject arg_object = args.getJSONObject(0);
Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);
sendIntent.setType("image/jpg");
String uri = "@drawable/"+arg_object.getString("image")+".jpg";
int imageResource = context.getResources().getIdentifier(uri, null, context.getPackageName());
bm = BitmapFactory.decodeResource(context.getResources(), imageResource);
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
file = new File(extStorageDirectory, "image.png");
try {
outStream = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
sendIntent.putExtra(android.content.Intent.EXTRA_TEXT, arg_object.getString("image"));
this.cordova.getActivity().startActivity(sendIntent);
} catch (Exception e) {
System.err.println("Exception: " + e.getMessage());
callbackContext.error(e.getMessage());
return false;
}
}
return true;
}
}
一切順利，但是當我點擊「分享」按鈕，我得到的異常爲「類未找到」。 問題出現在上下文類中，試圖通過清理並刪除Google中給出的gen文件，但沒有任何結果。請幫我解決這個問題。

您是否在xml文件夾中由phonegap插件生成的xml中定義了插件類名稱。 –
是的，我已經定義了config.xml文件@ nikhil.thakkar –
你可以粘貼你的完整的類文件和config.xml嗎？ –
