Eclipse で次のような問題が発生しています。

MainActivity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@413da0c0 that was originally added here

誰かがこれを以前に見たことがありますか、またはこの問題を解決する方法を知っていますか? 私はコードを何度も見てきましたが、それを解決するために何ができるかを理解していません。

ImageView を取得して、AsyncTask の doInBackground で操作しようとしています。これはノーノーです。

これとそれへのすべての参照は、doInBackground() に含めるべきではありません。

ImageView img = (ImageView) findViewById(R.id.imageView1);

AsyncTaskのAndroid ドキュメントを読み、いくつかの例についてグーグルで検索してください。

基本的にやりたいことは、ビットマップを doInBackground() から AsyncTask の postExecute() に返すことです。次に、そこでビットマップを使用して ImageView を設定できます。

また、Android AsyncTask クラスに main() があるのはなぜですか?
