android - fragment 兼容性 onActivityResult() 不工作

Question

我一直在开发一个利用 android 可比性库 (android-support-v4) 的 android 应用程序。在 SDK 20 之前，我能够使用以下 uses-sdk 编译我的应用程序进入我的 list 。

<uses-sdk android:minSdkVersion="7" />  

我所有为结果开始 Activity 的 fragment 都正确收到了结果。

一天(在我更新到 SDK 20 之前)我正在修复 lint 问题，我添加了 android:targetSdkVersion根据 lint 标志的请求到 list ，我很快意识到我的 fragment 都没有收到他们的 onActivityResilt() 调用。

现在，自从我更新到 SDK 20.0.1，我不得不使用 android:targetSdkVersion在 uses-sdk进入我的 list ；否则永远不会生成 R.java。

这是我目前的 uses-sdk list 条目

<uses-sdk
    android:minSdkVersion="7"
    android:targetSdkVersion="16" />

目前由于这个奇怪的错误，我的应用程序目前仍然被破坏。
我已经尝试将我的兼容库更新为最新版本 r9。

我还仔细检查了我所有的 startActivityForResult()在 fragment 中调用。他们都通过 fragment 的方法使用正确的调用。

即

 this.startActivityForResult(intent, requestCode);

不是

 this.getActivity().startActivityForResult(intent, requestCode);

我目前的开发环境:

Android SDK 20.0.1
Android SDK Platform Tools 13
ADT 20.0.2

任何帮助将不胜感激，因为这个错误目前是阻止我进行最终 beta 测试的砖墙。

我查看了 /app/android-sdk-linux_86/tools/ant/build.xml:616发现下面一行抛出了null enabled="${manifestmerger.enabled}">
这是整个街区




我将尝试禁用 list 合并选项，看看会发生什么

编辑

从 project.properties 中删除 manifestmerger.enabled=true 似乎解决了我的问题。该项目现在可以编译并完美运行。我想我应该将此错误报告给 android 团队。我的 list 有以下条目

<uses-sdk android:minSdkVersion="7"  />

但是，如果我将 targetSdkVersion 提高到 7 以上，仍然不会调用 onActivityResult()，所以这并不能真正解决根本问题，但我的项目现在可以正常工作

Answer 1

在 fragment 中( 错误 startActivityForResult)

getActivty().startActivityForResult(intent, requestCode); 
// Cannot receive in fragment

在 fragment 中( 正确 startActivityForResult)

startActivityForResult(intent, requestCode); 
// use Fragment.startActivityForRusult()
// not Activity.startActivityForRusult()

Activity 中

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

在 fragment 中

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // Do Action
}
