Android Proguard：发布构建强制关闭

Question

我通过启用 minifyEnabled 属性生成了发布版本，当我尝试运行发布版本时，它强制关闭并显示以下日志。请帮我调试一下

java.lang.NullPointerException
        at MYPACKAGENAME.MainActivity.onCreateOptionsMenu(Unknown Source)
        at android.app.Activity.onCreatePanelMenu(Activity.java:2538)
        at android.support.v4.app.i.onCreatePanelMenu(Unknown Source)

这是我的 onCreateOptionsMenu 方法代码

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    //Set up ShareActionProvider's default share intent
    MenuItem shareItem = menu.findItem(R.id.action_share_main);
    mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(shareItem);
    mShareActionProvider.setShareIntent(getDefaultIntent());

    return super.onCreateOptionsMenu(menu);
}

Answer 1

问题是 ShareActionProvider 正在 stripped/obfuscated，但支持库需要它保持原样。

将此行添加到您的混淆器配置中，您应该设置为：

-keep class android.support.v7.widget.ShareActionProvider { *; }
