OnActivityResult () fragment compatibility not working

I am working on an Android application that uses the android comparison library (android-support-v4). Before SDK 20, I was able to compile my application with the following uses-sdk entry in my manifest.

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

All my fragments that started activity for the result got their results correctly.

One fine day (before I upgraded to SDK 20), I fixed problems with lint, and I added android:targetSdkVersion to the manifest to request the lint flag, and soon realized that none of my fragments received their onActivityResilt calls ( )

Now, when I upgrade to SDK 20.0.1, I am forced to use the android:targetSdkVersion in uses-sdk entry in my manifest; otherwise R.java is never generated.

Here is my current uses-sdk manifest entry

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

Currently, due to this odd error, my application is currently still not working. I tried updating my compatible library with the latest version of r9.

I also double-checked all my startActivityForResult() calls in fragments. All of them use the corresponding calls using the fragment method.

ie

  this.startActivityForResult(intent, requestCode);

not

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

My current development environment:

 Android SDK 20.0.1 Android SDK Platform Tools 13 ADT 20.0.2

Any help would be greatly appreciated, as this bug is currently a brick wall that prevents my final beta tests.

EDIT

Here is my output of ant debug

EDIT

I looked through /app/android-sdk-linux_86/tools/ant/build.xml:616 and found that the next line selected the null value enabled="${manifestmerger.enabled}">

here is the whole block

I will try to disable the manifest merge option and see what happens

EDIT

It would seem that removing manifestmerger.enabled = true from project.properties solved my problem. The project now compiles and works fine. I think I should report this error to the android team. My manifest has the following entry

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

However, onActivityResult () is still not called if I raise targetSdkVersion above 7, so this doesn’t really solve the root problem, but my project is now working fine

In fragment (False startActivityForResult)

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

In fragment ( Fix startActivityForResult)

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

In action

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

In fragment

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

Here are some suggestions:

  • If you just want the manifest to not have android:targetSdkVersion , you can right-click your project in the Project Explorer in Eclipse and select Android Tools > Clear Lint Markers .

  • Make sure that all your Fragment and Activity advanced classes extend the correct classes from the compatibility library ( android.support.v4.app.Fragment and android.support.v4.app.FragmentActivity ), and none of them accidentally extends them into framework ( android.app.Fragment and android.app.Activity ).

In addition, it seems strange to me that your project does not compile if you install targetSdkVersion on anything other than 16. Is there any specific problem indicated in the "Problems / Console / Lint" window? Also check if you have another goal and / or is selected as Project Build Target (right-click the project, Properties > Android ).

There is an error in the compatibility package (see this and this )

After downloading the latest ADT, make sure you also overwrite your support bank in your project with this:

android-sdk\extras\android\support\v4\android-support-v4.jar

Perhaps you are using an old jar when working with the latest ADT.

Otherwise, I would expect your fragments to not receive their onActivityResult () calls if the parent activity did not super.onActivityResult(requestCode, resultCode, data);

EDIT

Explicitly adding this was necessary for my project:

 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.dualPane); fragment.onActivityResult(requestCode, resultCode, data); }
