Domanda

Ho un'app Android che utilizza ActionBarsherlock & ViewPagertabs. Io uso eclissi per scrivere e costruirlo, e funziona bene fino a quando provo a costruirlo con la formica. Ecco cosa ho fatto:

Vai alla cartella ActionBarsherlock, esegui "Android Aggiorna Lib-Project --Path."
Vai alla cartella ViewPagertabs, esegui "Android Aggiorna Lib-Project --Path." anch'io
Vai alla cartella App, Esegui "Android Aggiorna Progetto --Path."

Esegui "e debug" sotto Cartella App e ho ottenuto gli errori seguenti:
:
[javac] C:\Android\TestApp\src\com\test\App\TestActivity.java:46: cannot find symbol [javac] symbol : method getSupportActionBar() [javac] location: class com.test.App.TestActivity [javac] final ActionBar ab = getSupportActionBar(); [javac] ^
.
Quindi la domanda n. 1: Ho riferimenti di biblioteca corretti nel progetto App.Properties e ActionBarsherlock & ViewPagertabs potrebbero essere costruiti con successo, perché ottengo ancora questi errori?
C'è una soluzione alternativa per questo problema - copia tutte le classi.Jar con la cartella Bin della Biblioteca nella cartella delle LIF di app e esegui di nuovo "Ant Debug". Ma ho bisogno di eliminare questi file .jar in una cartella delle libs dell'app dopo tutti i file di app .java potrebbero essere compilati.
Esecuzione di "ANT Debug" Dopo questo, riceverò gli errori seguenti:

.
La mia domanda n. 2 è: Come posso risolvere questo problema?
Grazie!

Soluzione

I finally resolve it myself. I find that there's a android-support-v4.jar in ViewPagerTabs' libs folder. The solution is -- deleting this android-support-v4.jar, then make ViewPagerTabs depend on ActionBarSherlock (because ActionBarSherlock actually have one copy of Support Package).

I hope it's useful for people who wants to use ActionBarSherlock & ViewPagerTabs in one application and use Ant to built his/her application. Good luck.

Altri suggerimenti

You stated its because both library have android-support-v4.jar. See @porter-liu answer for non-maven builds.

For people using maven, set your ViewPager dependancy as:

    <dependency>
        <groupId>com.viewpagerindicator</groupId>
        <artifactId>library</artifactId>
        <version>2.4.1</version>
        <type>apklib</type>
        <exclusions>
            <exclusion>
                <groupId>com.google.android</groupId>
                <artifactId>support-v4</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

The exclusion tag stops the double import fixing the issue.

When you update lib-project, you're updating the project so that it compiles as a library. There's a separate step to update your main project so that it sees the library it requires.

For each library project you're going to use, run

android update project --library ../pathToTheLibrary
