しかし、しばらくすると、次のように表示されます。

今、私もこれを手に入れています、

この不正行為のために本当にイライラしています。コードは同じですが、完全に実行される場合もあれば、そうでない場合もあり、上記のエラーが表示されます。

私はawsを初めて使用します。cognito idが設定に保存されることを理解しています。

このコードを Utils.Java に追加します

    private static CognitoCachingCredentialsProvider getCredProvider(Context context) {
    if (sCredProvider == null) {
        ClientConfiguration clientConfiguration = new ClientConfiguration();
        clientConfiguration.setConnectionTimeout(30000);
        clientConfiguration.setSocketTimeout(30000);
        sCredProvider = new CognitoCachingCredentialsProvider(
                context.getApplicationContext(),
                Constants.COGNITO_POOL_ID,
                Regions.fromName(Constants.COGNITO_POOL_REGION),clientConfiguration);
    }
    return sCredProvider;
};

amazonS3Client は次のようになります。

     public static AmazonS3Client getS3Client(Context context) {
    if (sS3Client == null) {
        sS3Client = new AmazonS3Client(getCredProvider(context.getApplicationContext()));
        sS3Client.setRegion(Region.getRegion(Regions.fromName(Constants.BUCKET_REGION)));

    }
    return sS3Client;
};
