我正在编写一个代码，其中允许用户使用Intent向日历中添加事件，但每当我尝试将事件插入较低版本时，会出现应用程序已停止的错误信息：
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.EDIT typ=vnd.android.cursor.item/event (has extras) }
AndroidManifest.xml:-
<uses-permission android:name="android.permission.READ_CALENDAR"> </uses-permission>
<uses-permission android:name="android.permission.WRITE_CALENDAR"> </uses-permission>
Java代码：
final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
if (Build.VERSION.SDK_INT >= 14) {
Intent intent = new Intent(Intent.ACTION_INSERT).setData(Events.CONTENT_URI)
.putExtra(Events.TITLE, "Yoga")
.putExtra(Events.DESCRIPTION, "Group class")
.putExtra(Events.EVENT_LOCATION, "The Gym");
startActivity(intent);
} else {
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra(Events.TITLE, "Yoga");
intent.putExtra(Events.DESCRIPTION, "Group class");
intent.putExtra(Events.EVENT_LOCATION, "The Gym");
startActivity(intent);
}
}
});
}
Manifest.xml:-
