android – 片段兼容性onActivityResult()不起作用

概述我一直在研究一个利用 android可比性库( android-support-v4)的android应用程序.在SDK 20之前,我能够在清单中使用以下uses-sdk条目编译我的应用程序. <uses-sdk android:minSdkVersion="7" /> 我开始为结果活动的所有片段都能正确地获得结果. 有一天(在我更新到SDK 20之前)我正在修复lint问题,并且我根据lint标 我一直在研究一个利用 android可比性库( android-support-v4)的androID应用程序.在SDK 20之前,我能够在清单中使用以下uses-sdk条目编译我的应用程序.

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

我开始为结果活动的所有片段都能正确地获得结果.

有一天(在我更新到SDK 20之前)我正在修复lint问题,并且我根据lint标志的请求将manifest：targetSdkVersion添加到清单中,我很快意识到我的所有片段都没有接收到他们的onActivityResilt()调用.

现在每次我更新到SDK 20.0.1后,我都被迫在清单中的uses-sdk条目中使用androID：targetSdkVersion;否则R.java永远不会生成.

这是我当前的uses-sdk清单条目

<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打破.
我试过更新我的兼容库最新版本r9.

此外,我已经仔细检查了片段中的所有startActivityForResult()调用.他们都通过片段的方法使用正确的调用.

即

this.startActivityForResult(intent,requestCode);

不

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

我目前的开发环境：

AndroID SDK 20.0.1AndroID SDK Platform Tools 13ADT 20.0.2

任何帮助将不胜感激,因为这个BUG目前是阻止我最终beta测试的砖墙.

BUILD Failed /app/androID-sdk-linux_86/tools/ant/build.xml:616: null

Total time: 2 seconds

编辑

我查看了/app/androID-sdk-linux_86/tools/ant/build.xml:616,发现以下行抛出了null enabled =“${manifestmerger.enabled}”>

这是整个街区

我将尝试禁用清单合并选项,看看会发生什么

编辑

似乎从project.propertIEs中删除manifestmerger.enabled = true已经解决了我的问题.该项目现在编译并完美运行.我想我应该把这个BUG报告给androID团队.我的清单有以下条目

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

但是如果我将targetSdkVersion提高到7以上仍然没有调用onActivityResult(),所以这并没有真正解决root问题,但我的项目现在正常工作

解决方法 在Fragment中(错误的startActivityForResult)

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

在Fragment中(正确的startActivityForResult)

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

在活动中

@OverrIDeprotected voID onActivityResult(int requestCode,int resultCode,Intent data) {    super.onActivityResult(requestCode,resultCode,data);}

在片段中

@OverrIDeprotected voID onActivityResult(int requestCode,Intent data) {    // Do Action}
