在这里写在onNewIntent()方法不工作,我只设置的setContentView的code是一个万阿英,蒋达清?
和,这是明显的

解决方案
改变你的活动launchmode清单中下面给出,让我知道结果,
的android:launchMode =singleTop

}
here the code written in onNewIntent() method is not working I setting the setcontentView only is that a probelm?
and this is the manifest
<application
android:icon="@drawable/icon"
android:label="@string/app_name">
<activity
android:name=".TweetToTwitterActivity"
android:label="@string/app_name"
android:launchMode="singleInstance">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<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:scheme="tweet-to-twitter-blundell-01-android" />
</intent-filter>
</activity>
</application>
解决方案
change your activity launchmode in manifest as given below and let me know the results,
android:launchMode="singleTop"
