android - Twitter Oauth 回调 getOAuthRequestToken null

Question

我在这里使用应用程序的示例 https://github.com/itog/Twitter4j-android-Sample它正在工作。我在我的应用程序中使用了相同的方法，但当我在线时它返回 null

static final String CALLBACK_URL = "oauth://t4jsample"; [Copy the same as the Sample]
requestToken = twitter.getOAuthRequestToken(CALLBACK_URL);

这是我的 list

<activity
        android:name="com.my.app.SharePreviewActivity"
        android:screenOrientation="portrait"
        android:theme="@style/Theme.Fullscreen"
        android:windowSoftInputMode="stateAlwaysHidden|adjustPan" >

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data
                android:host="t4jsample"
                android:scheme="oauth" />
        </intent-filter>
    </activity>

这是我从示例应用程序中复制的其他代码。

private void askOAuth() {
    ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
    configurationBuilder.setOAuthConsumerKey(CONSUMER_KEY);
    configurationBuilder.setOAuthConsumerSecret(CONSUMER_SECRET);
    Configuration configuration = configurationBuilder.build();
    twitter = new TwitterFactory(configuration).getInstance();

    try {
        requestToken = twitter.getOAuthRequestToken(CALLBACK_URL);
        Toast.makeText(this, "Please authorize this app!",
                Toast.LENGTH_LONG).show();
        this.startActivity(new Intent(Intent.ACTION_VIEW, Uri
                .parse(requestToken.getAuthenticationURL())));
    } catch (TwitterException e) {
        e.printStackTrace();
    }
}

Answer 1

经过一番挣扎，我设法发现我忘记了

• 勾选了 twitter jar 库(我真傻!)
• 增加了 HTTP 的安全性

您需要为您的应用设置最低可用的 sdk

if (android.os.Build.VERSION.SDK_INT > 8) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                .permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }

瞧，它会起作用的。
