解决方案

我是个白痴-1给我。我设置的意图NO_HISTORY标志
我知道这是一个历史问题，我应该已经张贴code和它本来是显而易见的。

I have a PreferenceActivity that has a Preference on it. When the preference launches an activity using startActivity, the PreferenceActivity is stopped and removed by the OS.

I would like the user to return to the original PreferenceActivity instead of having it be finished and removed by the operating system.

The OS is removing the activity but I cannot tell why. HOw can I tell where/which code is calling finish on my activity?

@Override
protected void onClick() {
    // TODO Auto-generated method stub
    super.onClick();

    log("click");

    Intent sintent = new Intent(context, MusicPrefActivity.class);
    context.startActivity(sintent);

}

    <activity
        android:name=".ui.prefs.RokuPrefActivity"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar" >
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />
        </intent-filter>
    </activity>


    <activity
        android:name=".ui.prefs.MusicPrefActivity"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar" >
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />
        </intent-filter>
    </activity>

解决方案

I'm an idiot -1 to me. I was setting NO_HISTORY flag on intent I knew it was a history issue, I should have posted code and it would have been obvious.
