版本2.2（级别8）上的Android支持库ActionBar NullPointerException-与preferences.xml冲突

[英]Android Support Library ActionBar NullPointerException on version 2.2 (level 8) - conflict with preferences.xml

问题描述

I am using the v7 Support Library to show an ActionBar on Android 2.x. 我正在使用v7支持库在Android 2.x上显示ActionBar。

When I deploy the app to the device in my IDE (Intellij IDEA) the app works fine. 当我将应用程序部署到我的IDE（Intellij IDEA）中的设备时，该应用程序运行良好。

When I build and package the app to be deployed to the Play Store using maven, I find that I get the following exception when I install and run the packaged app on my device and the app crashes. 当我使用maven构建和打包要部署到Play商店的应用程序时，发现在设备上安装并运行打包的应用程序时出现以下异常，导致应用程序崩溃。 (It fails on the v8 simulator too). （它在v8模拟器上也失败）。 It works fine in both scenarios on android v4.3. 在android v4.3的两种情况下都可以正常工作。

Any idea why this would be crashing when built with maven? 知道为什么用Maven编译时会崩溃吗？

I have the following dependencies in maven: 我在Maven中具有以下依赖关系： 

<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>

and the following maven-android-plugin configured: 并配置了以下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>

UPDATE UPDATE

It has taken a while, but I have discovered that when I have the res/xml/preferences.xml file with PreferenceScreen settings then it causes this crash. 花费了一段时间，但是我发现当我使用带有PreferenceScreen设置的res / xml / preferences.xml文件时，会导致此崩溃。 If I remove this file, then it does not crash. 如果删除此文件，则不会崩溃。 Anyone know why that could cause this issue? 有人知道为什么会导致此问题吗？

Do you abslutely need features of android-maven-plugin version 3.8.2 ? 您绝对需要android-maven-plugin版本3.8.2吗？ It seems to be bugy. 好像是马车。

A similar problem appeared in our project after updating android-maven-plugin from version 3.8.0 to 3.8.2 . 将android-maven-plugin从3.8.0到3.8.2后，我们的项目中出现了类似的问题。

Falling back to version 3.8.0 solved the problem. 退回到版本3.8.0解决了该问题。

Symptoms: 症状：
Our conclusion is that the problem was in the linking of the apklib, all ressources (layouts, drawables...) referenced seemed to be disaligned. 我们的结论是，问题出在apklib的链接中，所有引用的资源（布局，可绘制对象...）似乎都没有对齐。 For example a layout or a drawable was displayed instead of another. 例如，显示的是布局或可绘制对象，而不是其他。 Application was crashing when accessing to a missing reference/id in a layout (the reference was not present because the wrong layout was loaded). 访问布局中缺少的引用/ ID时，应用程序崩溃（该引用不存在，因为加载了错误的布局）。
