無法在android中顯示圖表

我想在使用achartengine庫的android中創建圖表。得到一個仿真的運行後它只是顯示「對不起，您的應用程序意外closed.try again.force接近」無法在android中顯示圖表

我有一個疑問只有Manifest.xml文件，是我的清單文件懷特？如果沒有請我清楚。

請找我的消息來源，以及manifest.xml中的logcat中參考

logcat的

org.achartengine.GraphicalActivity在您的清單中沒有被發現，因爲它是圖書館的一部分。

將以下行添加到您的project.properties文件中以啓用清單的自動合併。

manifestmerger.enabled=true

project.properties file

編輯：

我以爲achartengine是一個庫項目。原來這是一個JAR。

您需要將活動添加到您的清單：

<activity android:name="org.achartengine.GraphicalActivity" />

你能告訴我去哪裏我提這line manifestmerger.enabled = true在manifest.xml文件中 – Rohith

不是清單文件，而是** project.properties **文件。看看截圖。 –

儘管如果我遵循了你的建議，模擬器在logcat上顯示相同的錯誤。 – Rohith

您需要添加活動的AndroidManifest.xml是這樣的：

<activity android:name="org.achartengine.GraphicalActivity"></activity>
