Question

我正在使用v7支持库在Android 2.x上显示ActionBar。

当我在IDE（Intellij IDEA）中将应用程序部署到设备时，应用程序运行正常。

当我使用maven构建和打包要部署到Play商店的应用程序时，我发现当我在设备上安装并运行打包应用程序并且应用程序崩溃时，我收到以下异常。（它也在v8模拟器上失败了）。它在android v4.3的两个场景中都能正常工作。

知道为什么在使用maven构建时会崩溃？

我在maven中有以下依赖项：

<dependencies>
    <dependency>
        <groupId>android</groupId>
        <artifactId>android</artifactId>
        <version>4.0_r3</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>android.support</groupId>
        <artifactId>compatibility-v7-appcompat</artifactId>
        <version>19.0.1</version>
        <type>jar</type>
    </dependency>
    <dependency>
        <groupId>android.support</groupId>
        <artifactId>compatibility-v7-appcompat</artifactId>
        <version>19.0.1</version>
        <type>apklib</type>
    </dependency>
    <dependency>
        <groupId>android.support</groupId>
        <artifactId>compatibility-v13</artifactId>
        <version>19.0.1</version>
        <type>jar</type>
    </dependency>
</dependencies>

并配置以下maven-android-plugin：

<build>
    <plugins>
        <plugin>
            <groupId>com.jayway.maven.plugins.android.generation2</groupId>
            <artifactId>android-maven-plugin</artifactId>
            <version>3.8.2</version>
            <configuration>
                <sdk>
                    <platform>14</platform>
                </sdk>
            </configuration>
            <extensions>true</extensions>
        </plugin>
    </plugins>
</build>

更新

它花了一段时间，但我发现当我有带有PreferenceScreen设置的res / xml / preferences.xml文件时，它会导致此崩溃。如果我删除此文件，它不会崩溃。任何人都知道为什么会导致这个问题？

Answer 1

您是否绝对需要android-maven-plugin版本3.8.2的功能？这似乎很烦人。

将android-maven-plugin从版本3.8.0更新为3.8.2后，我们的项目中出现了类似的问题。

回到版本3.8.0解决了这个问题。

<强>症状：
我们的结论是问题在于apklib的链接，引用的所有资源（布局，drawables ......）似乎都是不对齐的。例如，显示布局或可绘制而不是另一个。当访问布局中缺少的引用/ id时，应用程序崩溃（由于加载了错误的布局，引用不存在）。
